Snapser CLI Tool

Snapser CLI Tool

Dependencies

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. Some of the commands also need docker.

Installation

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

Once you have Python and Pip installed

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

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**.

Upgrade

Upgrade your snapctl version

pip install --user snapctl --upgrade

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.

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

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_access_key = <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 --version

You should see the latest snapctl version in the output

Advanced Setup

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

[profile personal]
snapser_access_key = <key>

[profile professional]
snapser_access_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 my_profile_name with every command to tell Snapser to use a particular profile.

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

snapctl snapend clone --help

# Clone your Snapend
# $gameId = Game Id
# $snapendName = Name of your new Snapend
# $env = One of development, staging

# Example:
# snapctl snapend clone --game-id 2581d802-aca-496c-8a76-1953ad0db165 --name new-snapend --env development --manifest-path "C:\Users\name\Downloads\snapser-ox1bcyim-manifest.json" --blocking
snapctl snapend clone --game-id $gameId --name $snapendName --env $env --manifest-path "$pathToManifest"
snapctl snapend clone --game-id $gameId --name $snapendName --env $env --manifest-path "$pathToManifest" --blocking

4. Apply Snapend Changes

Apply changes to your Snapend from a manifest. You should have the latest manifest before applying changes. This is to prevent a user stomping over someone elses changes. Passing the blocking flag ensures your CLI command waits till the update is complete.

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

# Apply changes to a snapend via manifest
# $pathToManifest = Path to the manifest file; should include the file name
# Example:
# snapctl snapend apply --manifest-path "C:\Users\name\Downloads\snapser-ox1bcyim-manifest.json" --blocking
snapctl snapend apply --manifest-path "$pathToManifest"
snapctl snapend apply --manifest-path "$pathToManifest" --blocking

5. Update Snapend BYOSnap or BYOGs versions

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

6. Get the Snapend state

Get the Snapend state

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