Snapser CLI

Snapser has developed a CLI tool called snapctl that can be used on MaxOSX, Linux and Windows machines. Snapctl will be the best way for game studios to integrate Snapser into their build pipelines.

What's new in the latest version?

Breaking Changes

1. Renamed SDK type server to api-key to be consistent with the Snapser Web app.

Features

1. Added support for Bring your own Workstation commands. This enables local debugging for your BYOSnaps while clients continue to access your cloud Snapend APIs.

snapctl byows attach --snapend-id $snapend_id --byosnap-id $byosnap_id --http-port $http_port

snapctl byows reset --snapend-id $snapend_id

Requirements

Python 3.X and Pip

The Snapser CLI tool depends on Python 3.X and Pip. MacOS comes pre installed with Python. But please make sure you are running Python 3.X. On Windows, you can download Python 3.X from the Windows store.

Docker

Some of the commands also need docker. You can download the latest version of Docker from the Docker website.

IMPORTANT: Open up Docker desktop and settings. Make sure this setting is disabled Use containerd for pulling and storing images. This is because Snapser uses Docker to build and push images to the Snapser registry. Having this setting enabled will cause issues with the Snapser CLI tool.

Installation

Pip

Installing PIP on MacOS

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python3 get-pip.py

Installing PIP on Windows

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py

Pipx

Now a days, pipx is recommended for CLI tools. Once you have Python and Pip installed, lets install Pipx.

python3 -m pip install --user pipx
python3 -m pipx ensurepath

Install Snapctl

• If you chose to use Pip

pip install --user snapctl

If you also have Python 2.X on your machine, you may have to run the following command instead

pip3 install --user snapctl

• If using, Pipx

pipx install snapctl

IMPORTANT: After you install snapctl you may have to add the python bin folder to your path. For example, on MacOSX this is usually ~/Library/Python/3.9/bin. On Windows this is usually C:\Users\username\AppData\Roaming\Python\Python39\Scripts. For, Windows users, after running pipx ensurepath, you may need to restart your terminal (Command Prompt, PowerShell, or Windows Terminal) for the PATH changes to take effect.

Upgrade

Upgrade your snapctl version

• If using Pip

pip3 install --user snapctl --upgrade

• If using Pipx

pipx upgrade snapctl

Setup

Get your Snapser Access Key

Log in to your Snapser account. Click on your user icon on the top right and select, User Account. In the left navigation click on Developer which will bring up your Personal API Key widget. If you have not generated an API Key yet click on the Generate button to generate a new key. You can generate up to 3 API Keys per user account.

IMPORTANT: Please make sure you save your API key in a safe place. You will not be able to see it again.

Setup a local config

You have three ways to pass the API key to Snapctl

1. Pass it via a command line argument with every command
2. Pass it via an environment variable
3. Pass it via a config file (recommended)

Command line argument

Every Snapser command can take a command line argument --api-key <your_key>. This will take precedence over other methods.

Environment Variable

You can set an Environment variable SNAPSER_API_KEY=<your_key> and then run your snapctl commands. This will be evaluated after verifying if there is any command line argument.

Config file

Create a file named ~/.snapser/config. Open it using the editor of your choice and replace with your personal Snapser Access key. Save the file. Advantage of using this method is you can use the --profile argument with your snapctl command to use different API keys. NOTE: You may want to pass your own path instead on relying on the default one the CLI looks for. You can do so by setting an environment variable SNAPSER_CONFIG_PATH='<your_custom_path>'. Doing this will make sure that the CLI tool will look for the config file at that path.

[default]
SNAPSER_API_KEY=$your_api_key

Or you can run the following command

on MacOSX

# $your_api_key = Your Snapser developer key
echo -e "[default]\nSNAPSER_API_KEY=$your_api_key" > ~/.snapser/config

on Windows Powershell

# $your_api_key = Your Snapser developer key
echo "[default]
SNAPSER_API_KEY=$your_api_key" | Out-File -encoding utf8 ~\.snapser\config

Verify Snapctl installation

snapctl validate

Output will tell you if the Snapctl was able successfully validate your setup with the remote Snapser server or not.

Advanced Setup

Snapser by default supports access to multiple accounts. You can create multiple profiles in your Snapser config ~/.snapser/config.

[profile personal]
nSNAPSER_API_KEY=<key>

[profile professional]
nSNAPSER_API_KEY=<key>

You can then set an environment variable telling Snapser which profile you want to use.

# Mac
export SNAPSER_PROFILE="my_profile_name";

# Windows
setx SNAPSER_PROFILE="my_profile_name";

Or you can pass --profile professional with every command to tell Snapser to use a particular profile.

Command variable name nomenclature

All commands follow these rules with their input variables

1. A variable that is named *path = CLI tool expects a path to a folder
2. A variable that is named *filename = CLI tool expects the name of the file, without the path.
3. A variable that is named *path_filename = CLI tool expects the full path. The folder up to the name of the file.

Commands

Run the following to see the list of commands Snapser supports

snapctl --help

1. Snaps

Snapctl commands for snaps

1. snaps help

See all the supported commands.

# Help for the byosnap command
snapctl snaps --help

2. snaps enumerate

2. BYO Snap - Bring your own Snap

Snapctl commands for your custom code

1. byosnap help

See all the supported commands.

# Help for the byosnap command
snapctl byosnap --help

2. byosnap generate-profile

This command generates a base BYOSnap profile. You will have to update the values within this file and then you can use it in commands like publish and sync. It is recommended that you save this file at the root of your BYOSnap code and commit it to version control.

# Help for the byosnap command
snapctl byosnap generate-profile --help

# Generate your BYOSnap profile
# $output_path = Directory where you want the BYOSnap profile to be saved.
# $profile_filename = Name of the BYOSnap profile you want to give. Only .json, .yaml, .yml extensions
#   are allowed. If you do not pass `--profile-filename` then Snapser choses
#   `snapser-byosnap-profile.json` as the filename.
snapctl byosnap generate-profile --out-path $output_path --profile-filename $profile_filename
snapctl byosnap generate-profile --out-path /Users/DevName/Development/SnapserEngine/byosnap-python --profile-filename=my-byosnap-profile.json
snapctl byosnap generate-profile --out-path /Users/DevName/Development/SnapserEngine/byosnap-python --profile-filename=my-byosnap-profile.yaml

3. byosnap validate-profile

This command validates your BYOSnap profile.

# Help for the byosnap command
snapctl byosnap validate-profile --help

# Validate your BYOSnap profile
# $path = Directory Path to where your BYOSnap Profile is located. No need to add the file name.
# $resources_path = Optionally, you can place your BYOSnap profile at your resources path
# $profile_filename = Optional parameter. Name of your BYOSnap profile.
#   If you do not pass `--profile-filename` then
#   Snapser choses the default `snapser-byosnap-profile.json` as the filename to validate
snapctl byosnap validate-profile --path $path
snapctl byosnap validate-profile --resources-path $resources_path --profile-filename $profile_filename
snapctl byosnap validate-profile --path /Users/DevName/Development/SnapserEngine/byosnap-python
snapctl byosnap validate-profile --path /Users/DevName/Development/SnapserEngine/byosnap-python --profile-filename my-byosnap-profile.yaml

4. byosnap publish

This command allows you to create and publish your BYOSnap. Running this command will first create a BYOSnap namespace on Snapser if not present. Then it will build and publish your code to your own private ECR repo on Snapser. Finally it will assign a version to your BYOSnap so that you can deploy it.

Requirements:

• This command needs docker.
• This command needs a BYOSnap profile. BYOSnap profile, holds information about your BYOSnap like, name, description, etc and hardware requirements like CPU, Memory. We recommend you store this file at the root of your BYOSnap and also add it to version control. You can generate it using snapctl byosnap generate-profile --out-path $outputPath --profile-filename $profileName.

# Help for the byosnap command
snapctl byosnap publish --help

# Create and publish your BYOSnap
# $byosnap_id = Snap ID for your snap
# $version = Semantic version for your snap Eg: v0.0.1
# $code_root_path = Local code path where your Dockerfile is present
# $resources_path = Optional path to the resources directory in your Snap. This ensures, you are not forced to put the Dockerfile, snapser-byosnap-profile.json, swagger.json and README.md at the root directory of your Snap.
# $profile_filename = Optional parameter. Name of your BYOSnap profile.
#   If you do not pass `--profile-filename` then
#   Snapser choses the default `snapser-byosnap-profile.json` as the filename to validate
# $skip-build = true/false. Default is false. Pass this flag as true to skip the build and head straight to tag and push. Build step needs to run and tag using the --tag you pass to the publish-image command for this to work. Make sure the tag matches the version number you are passing.
# Example:
snapctl byosnap publish --byosnap-id byosnap-jinks-flask --version "v0.0.1" --path /Users/DevName/Development/SnapserEngine/byosnap-python --profile-filename $profile_filename
snapctl byosnap publish --byosnap-id $byosnap_id --version $version --path $code_root_path
byosnap publish --byosnap-id byosnap-python --version "v1.0.0" --path /Users/AJ/Development/byosnap-python --profile-filename my-byosnap-profile.yaml

5. byosnap sync

This command is for development purposes. It allows developers to rapidly build, update and push their BYOSnap to a dev Snapend. Simply, make changes to your code locally, and then run this command to deploy your BYOSnap straight to your development Snapend.

Requirements:

• This command needs docker.

IMPORTANT: This command will only work for Dev Snapends. Additionally if the version you are using in this command happens to be used by a staging or a production snapend then sync will not work. We do this to ensure that your staging and production BYOSnap images do not get impacted.

# Help for the byosnap command
snapctl byosnap sync --help

# Deploy local code straight to your Snapend
# $byosnap_id = Snap ID for your snap
# $code_root_path = Local code path where your Dockerfile is present
# $resources_path = Optional path to the resources directory in your Snap. This ensures, you are not forced to put the Dockerfile, swagger.json and README.md in the root directory of your Snap.
# $skip-build = true/false. Default is false. Pass this flag as true to skip the build and head straight to tag and push. Build step needs to run and tagged using the --tag you pass to the publish-image command for this to work.
# $tag = Semantic version for your snap Eg: v0.0.1
# $version =
# $snapend_id = Dev Snapend Id
# Example:
snapctl byosnap sync --byosnap-id byosnap-jinks-flask --path /Users/DevName/Development/SnapserEngine/byosnap-python --version "v0.0.11" --snapend-id "jxmmfryo"
snapctl byosnap sync --byosnap-id $byosnap_id --path $code_root_path --version $version --snapend-id $snapend_id

6. byosnap create

11. byosnap publish-version

Publish a new version for your Snap. Only after your Snap version is published, you will be able to use your snap in your Snapend. This command should be run after push or publish-image commands.

IMPORTANT: You need to have $byosnapProfile to run this command. BYOSnap profile is a JSON configuration of your BYOSnap for the development, staging and production environments. You can generate a base version of this file using the snapctl byosnap generate-profile --out-path $outputPath --profile-filename $profileName command.

# Help for the byosnap command
snapctl byosnap publish-version --help

# Publish a new image
# $byosnap_id = Snap ID for your snap
# $image_tag = An image tag for your snap
# $version = Semantic version for your snap Eg: v0.0.1
# $byosnap_profile_path = Path to the snapser-byosnap-profile.json BYOSnap profile to configure dev, stage and prod settings for this snap. You can generate a base version of this file using the `snapctl byosnap generate-profile --out-path $outputPath --profile-filename $profileName` command
# Example:
# snapctl byosnap publish-version --byosnap-id byosnap-jinks-flask --tag my-first-image --version v0.0.1 --path /Users/DevName/Development/SnapserEngine/byosnap-python
snapctl byosnap publish-version --byosnap-id $byosnap_id --tag $image_tag --version $version --path $byosnap_profile_path

3. BYO Workstation - Bring your own Workstation

Snapctl commands for bring your own workstation. This command allows you to attach your workstation to a Snapend. This is useful for testing and debugging your BYOSnap code.

1. byows help

See all the supported commands

# Help for the byows command
snapctl byows --help

2. byows attach

Attach your workstation to a Snapend. It should be noted, that this command outputs a file byows_env_setup.sh|ps1 at ~/.snapser/ directory. This file contains the environment variables that the BYOWS technology will need to route internal calls to the appropriate Snaps.

# Attach your workstation to a Snapend
# $snapend_id = Snapend Id
# $byosnap_id = BYOSnap Id
# $http_port = Port that your local server is running on
snapctl byows attach --snapend-id $snapend_id --byosnap-id $byosnap_id --http-port $http_port

Then run, the following command in a separate terminal window, to setup the BYOWS environment variables.

# MacOSX
source ~/.snapser/byows_env_setup.sh
# Windows
.\.snapser\byows_env_setup.ps1

Then start your BYOSnap local server in the same tab that has the environment variables set up. This will ensure that the BYOSnap code can access the internal SDK and other Snaps in your Snapend.

4. BYO Game Server - Bring your own Game Server

Snapctl commands for your custom game server

1. byogs help

See all the supported commands

# Help for the byogs command
snapctl byogs --help

2. byogs publish

Publish your custom game server image. This commend replaces the old way of creating, publishing image and then publishing the byogs. Now all you have to do is publish your image and create a fleet using the web portal.

IMPORTANT: Take note of the hardware architecture of machine and your Dockerfile commands. Commands in docker file may be hardware architecture specific. Snapser throws a warning if it detects a mismatch.

# Help for the byogs command
snapctl byogs publish --help

# Publish a new image
# $image_tag = An image tag for your snap
# $code_root_path = Local code path where your Dockerfile is present
# $resources_path = Optional path to the resources directory. This ensures, you are not forced to put the Dockerfile at the root directory of your Game Server code.
# $skip-build = Default is false. Pass this flag as true to skip the build and head straight to tag and push. Build step needs to run and tagged using the --tag you pass to the publish-image command for this to work.
# Example:
# snapctl byogs publish --tag my-first-image --path /Users/DevName/Development/SnapserEngine/game_server
snapctl byogs publish --tag $image_tag --path $code_root_path
snapctl byogs publish --tag $image_tag --path $code_root_path --resources-path $resources_path
snapctl byogs publish --tag $image_tag --skip-build

3. byogs sync

This command allows developers to rapidly build, update and push their BYOGs out to a Snapend fleet. Simply, make changes to your code locally, and then run this command to deploy your BYOGs straight to your Snapend fleet.

# Help for the byogs command
snapctl byogs sync --help

# Publish a new image
# $code_root_path = Local code path where your Dockerfile is present
# $resources_path = Optional path to the resources directory in your Snap. This ensures, you are not forced to put the Dockerfile, swagger.json and README.md in the root directory of your Snap.
# $skip-build = true/false. Default is false. Pass this flag as true to skip the build and head straight to tag and push. Build step needs to run and tagged using the --tag you pass to the publish-image command for this to work.
# $image_tag = An image tag for your snap. Note snapctl adds a timestamp, allowing you to use the same command.
# $snapend_id = Snapend Id
# $fleet_names = Comma separated fleet names
# Example:
snapctl byogs sync --path /Users/DevName/Development/SnapserEngine/game_server --tag my-first-image --snapend-id "jxmmfryo" --fleet-names "my-fleet,my-second-fleet"
snapctl byosnap sync --path $code_root_path --tag $image_tag --snapend-id $snapend_id --fleet-names $fleet_names

4. byogs build

Build your custom game server image.

# Help for the byogs command
snapctl byogs build --help

# Publish a new image
# $image_tag = An image tag for your snap
# $code_root_path = Local code path where your Dockerfile is present
# Example:
# snapctl byogs build byosnap-jinks-gs --tag my-first-image --path /Users/DevName/Development/SnapserEngine/game_server
snapctl byogs build --tag $image_tag --path $code_root_path

5. byogs push

Push your custom game server image.

# Help for the byogs command
snapctl byogs push --help

# Publish a new image
# $image_tag = An image tag for your snap
# Example:
# snapctl byogs push byosnap-jinks-gs --tag my-first-image
snapctl byogs push --tag $image_tag

5. Application

Snapctl commands for your application

See all the supported commands

# Help for the byogs command
snapctl application --help

2. application create

Create an application

snapctl application create --name $app_name

3. application enumerate

List all the applications

snapctl application enumerate

6. Snapend Manifest

Snapctl commands for the Snapend manifest. Manifest is the representation of your Snapser backend stored as a JSON or YAML. The manifest can then be used to create, update your backend.

1. snapend-manifest help

See all the supported commands

# Help for the byogs command
snapctl snapend-manifest --help

2. Snapend Manifest Create

Create a Snapend manifest. It should be noted that the latest versions of the snap at the time of running the command is what gets added to the manifest. For example, say the analytics snap has versions v1.0.0, v1.1.0 available on the web portal. If you run the create command with --snaps analytics the v1.1.0 which is the latest at that moment in time, gets added to your manifest.

The output manifest file can then be used with the snapend create or snapend clone commands.

# Create a Snapend manifest file
# $name = Name for your backend, which is stored in the outputted manifest
# $env = One of DEVELOPMENT, STAGING or PRODUCTION
# $output_path_filename = Path and file name to store the manifest. The filename should end with .json or .yaml
# $snaps = Comma separated list of snap ids you want to add.  You can get the snap ids from the
#     `snapctl snaps enumerate --out-path ./snaps.json` command
# $features = Pass `WEB_SOCKETS` if you want to enable web sockets for your backend.
# Note: One of snaps or features is required
# Example:
#   snapend-manifest create --name my-dev-snapend --env DEVELOPMENT --snaps auth,analytics --add-features WEB_SOCKETS --out-path ./snapend-manifest.json

snapctl snapend-manifest create --name $name --env $env --snaps $snaps --features $features --out-path-filename $output_path_filename

3. Snapend Manifest Sync

Sync with an existing Snapend manifest. This command is idempotent and destructive.

• It ensures the input manifest gets replaced with the values you pass in --snaps and --features. For example: If your input manifest has a snap but you do not pass the snap in the --snaps, it will be removed from the output. Same goes for --features.
• Additionally, if a snap is present in the manifest and you pass it in as part of --snaps it will not be touched. But if a snap is not part of the manifest and you pass it in as part of --snaps it will be added with the latest version of the snap. For example, say the analytics snap has versions v1.0.0, v1.1.0 available on the web portal. If you run the sync command with --snaps analytics and you had v1.0.0 in the manifest then it wont be touched. However, if you did not have it in the manifest then the v1.1.0 which is the latest at that moment in time, gets added to your manifest.

IMPORTANT: If you are looking for a command to purely add or remove snaps or features, consider using the update command instead.

# Sync a Snapend manifest file
# $input_manifest = Path and file name of the current manifest. The filename should end with .json or .yaml
# $output_path_filename = Path and file name to store the manifest. The filename should end with .json or .yaml
# $snaps = Comma separated list of snap ids you want to have at the end. You can get the snap ids from # the `snapctl snaps enumerate --out-path ./snaps.json` command.
#   IMPORTANT: If your manifest has a snap but your --snaps does not. It will be removed.
# $features = Pass `WEB_SOCKETS` if you want to enable web sockets for your backend.
#   IMPORTANT: If your manifest has a feature but your --features does not. It will be removed.
# Note: One of snaps, and features is required
# Example:
#   snapctl snapend-manifest sync --manifest-path-filename ./snapser-jn86b0dv-manifest.yaml --add-snaps game-server-fleets --remove-snaps analytics --remove-features WEB_SOCKETS --out-path ./snapend-updated-manifest.yaml

snapctl snapend-manifest sync --manifest-path-filename $input_manifest --snaps $snaps --features $features--out-path-filename $output_path_filename

4. Snapend Manifest Upgrade

Upgrade all snaps or a list of snaps to the latest version of the snap available at that moment in time. If you do not pass in --snaps then all the snaps in the manifest will be upgraded. If you do pass a list of snaps then all snap Ids are expected to be valid.

# Update a Snapend manifest file
# $input_manifest = Path and file name of the current manifest. The filename should end with .json or .yaml
# $output_path_filename = Path and file name to store the manifest. The filename should end with .json or .yaml
# $snaps = (Optional) Comma separated list of snap ids you want to upgrade. You can get the snap ids
#   from the `snapctl snaps enumerate --out-path ./snaps.json` command
#   IMPORTANT: If the --snaps parameter is not provided then all snaps in the manifest will be upgraded
# Example:
# snapctl snapend-manifest upgrade --manifest-path-filename ./snapser-jn86b0dv-manifest.yaml --snaps game-server-fleets --out-path ./snapend-updated-manifest.yaml
# snapctl snapend-manifest upgrade --manifest-path-filename ./snapser-jn86b0dv-manifest.yaml --out-path ./snapend-updated-manifest.yaml

snapctl snapend-manifest upgrade --manifest-path-filename $input_manifest --out-path-filename $output_path_filename

snapctl snapend-manifest upgrade --manifest-path-filename $input_manifest --snaps $snaps --out-path-filename $output_path_filename

5. Snapend Manifest Update

Update your manifest. This command is additive and subtractive. It allows you to add or remove, snaps and features from an existing manifest. Unlike sync, this will only add or remove entities from your manifest, keeping the remaining part of the manifest intact. If your manifest has a snap and you pass it with --add-snaps then it will be ignored. However if you do not have a snap and you pass it with --add-snaps then the latest version of the snap will be added. If you pass a snap with --remove-snaps that is already not in the manifest, then it will be skipped. This ensures idempotency after the initial update is made to the snapend manifest.

IMPORTANT:

• All additions are performed before removals.
• If you are looking to have strict relation between your input (snaps + features) and your output manifest, consider using the sync command.

# Update a Snapend manifest file
# $input_manifest = Path and file name of the current manifest. The filename should end with .json or .yaml
# $output_path_filename = Path and file name to store the manifest. The filename should end with .json or .yaml
# $addSnaps = Comma separated list of snap ids you want to add to your manifest. You can get the snap ids from # the `snapctl snaps enumerate --out-path ./snaps.json` command.
# $removeSnaps = Comma separated list of snap ids you want to remove from your manifest. You can get the snap ids from # the `snapctl snaps enumerate --out-path ./snaps.json` command.
# $addFeatures = Pass `WEB_SOCKETS` if you want to enable web sockets for your backend.
# $removeFeatures = Pass `WEB_SOCKETS` if you want to disable web sockets for your backend.
# Note: One of add-snaps, remove-snaps, add-features or remove-features is required
# Example:
#   snapctl snapend-manifest update --manifest-path-filename ./snapser-jn86b0dv-manifest.yaml --add-snaps game-server-fleets --remove-snaps analytics --remove-features WEB_SOCKETS --out-path ./snapend-updated-manifest.yaml

snapctl snapend-manifest update --manifest-path-filename $input_manifest --add-snaps $addSnaps --remove-snaps $removeSnaps --add-features $addFeatures --remove-features $removeFeatures --out-path-filename $output_path_filename

snapctl snapend download --snapend-id $snapend_id --category $category --format $format --type $type --http-lib $http_lib --out-path $out_path

3. snapend create

Create a Snapend from an existing manifest. Passing the blocking flag ensures your CLI command waits till the new Snapend is up.

# Help for the crete command
snapctl snapend create --help

# Create a Snapend
# $app_id = App Id
# $path_to_manifest = Path to the manifest file; should include the file name
# Optionally override name and environment by passing the --name and --environment overrides
# Example:
# snapctl snapend create --manifest-path-filename $path_to_manifest --app-id $app_id  --blocking
snapctl snapend create --manifest-path-filename $path_to_manifest --app-id $app_id
snapctl snapend create --manifest-path-filename $path_to_manifest --app-id $app_id --blocking
snapctl snapend create --name $name --env $env --manifest-path-filename $path_to_manifest --app-id $app_id --blocking

4. snapend clone

Clone a Snapend from an existing manifest. Passing the blocking flag ensures your CLI command waits till the new Snapend is up.

# Help for the clone command
snapctl snapend clone --help

# Clone your Snapend
# $app_id = App Id
# $snapend_name = Name of your new Snapend
# $env = One of development, staging
# $path_to_manifest = Path to the manifest file; should include the file name
# Example:
# snapctl snapend clone --app-id 2581d802-aca-496c-8a76-1953ad0db165 --name new-snapend --env development --manifest-path-filename "C:\Users\name\Downloads\snapser-ox1bcyim-manifest.json" --blocking
snapctl snapend clone --app-id $app_id --name $snapend_name --env $env --manifest-path-filename "$path_to_manifest"
snapctl snapend clone --app-id $app_id --name $snapend_name --env $env --manifest-path-filename "$path_to_manifest" --blocking

5. snapend apply

Apply changes to your Snapend from a manifest. You should have the latest manifest before applying changes. Basically, when you download a manifest, Snapser adds an applied_configuration section to your manifest, which stores the state of the Snapend during export. Now, if someone manually updates the Snapend or a configuration of a Snap, you are no longer going to have the latest Snapend representation in the applied_configuration. This is how Snapser prevents you from stomping over someone elses changes.

You can optionally pass a --force flag telling Snapser to ignore any diffs it may find in the current state of the Snapend and the one in the applied_configuration field of your manifest. Essentially, this flag allows you to stomp over any changes and tell Snapser to force apply.

Separately, you can pass a blocking flag to make your CLI wait for the Snapend update to complete.

# Help for the apply command
snapctl snapend apply --help

# Apply changes to a snapend via manifest
# $path_to_manifest = Path to the manifest file; should include the file name
# --force = Optional flag to tell Snapser that you do not want it to check the diff between the Snapend states and just force apply the changes
# Example:
# snapctl snapend apply --manifest-path-filename "C:\Users\name\Downloads\snapser-ox1bcyim-manifest.json" --force --blocking
snapctl snapend apply --manifest-path-filename "$path_to_manifest"
snapctl snapend apply --manifest-path-filename "$path_to_manifest" --blocking
snapctl snapend apply --manifest-path-filename "$path_to_manifest" --force --blocking

6. snapend update

Update your BYOSnap or BYOGs versions for the Snapend

# Help for the byogs command
snapctl snapend update --help

# Update your Snapend with new BYOSnaps and BYOGs
# $snapend_id = Cluster Id
# $byosnaps = Comma separated list of BYOSnap ids and version.
# $byogs = Comma separated list of BYOGs fleet name, id and version.
# --blocking = (Optional) This makes sure the CLI waits till your Snapend is live.
# Note at least one of the two needs to be present
# Example:
# snapctl snapend update --snapend-id gx5x6bc0 --byosnaps byosnap-service-1:v1.0.0,byosnap-service--2:v1.0.0 --byogs byogs-fleet-one:gs-1:v0.0.1,my-fleet-two:gs-2:v0.0.4
# snapctl snapend update --snapend-id gx5x6bc0 --byosnaps byosnap-service-1:v1.0.0,byosnap-service--2:v1.0.0 --byogs fleet-one:v0.0.1,fleet-two:v0.0.4 --blocking
snapctl snapend update --snapend-id $snapend_id --byosnaps $byosnaps --byogs $byogs --blocking

7. snapend state

Get the Snapend state

# Help for the byogs command
snapctl snapend state --help

# $snapend_id = Cluster Id
# Example:
# snapctl snapend state gx5x6bc0
snapctl snapend state $snapend_id
