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.

[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.
