Config variables

Config variables are used to store secrets and pass environment-specific information to your applications running on AWS. They are managed via the CLI and passed into the application via environment variables.

Setting a config variable

apppack config set is used to set a config variable. For example, if you wanted to store a config variable named SECRET_KEY with the value this-is-a-secret for your app my-app, you would run:

Example

apppack -a my-app config set SECRET_KEY=this-is-a-secret

This command will store the value as an encrypted string in the AWS Parameter Store. It will also gracefully restart your application to add the environment variable immediately.

Note

The APPPACK_APPNAME configuration is already set for each app. If neither AWS_REGION nor AWS_DEFAULT_REGION are configured, they will be automatically set to the app's deployed region. If either one is set, the other will not be set automatically.

Modifying a config variable

Use the same process as above for setting a variable.

Removing a config variable

If you want to remove a config variable completely, you can run:

Example

apppack -a my-app config unset SECRET_KEY

This would remove the config variable SECRET_KEY from the app named my-app.

Listing config variables

You can list all the config variables for an app by running:

Example

apppack -a my-app config list
