Configuring your stack

Programs and packages use configuration variables for easy per-stack customization.

The pulumi config family of commands manage a stack’s configuration.

Each configuration setting inside of a stack has a key and a value. We will interact with settings using the keys. These keys include the package name and the variable name, as in aws:region which is the aws package’s region.

To set a variable, use the pulumi config set command with the key and value:

$ pulumi config set aws:region us-west-2

If the value is sensitive – like a password or token – pass --secret and it will be encrypted:

$ pulumi config set ahoy-pulumi:launchDarklyKey a76dFAKEg9321 --secret

To retrieve a variable’s current value, use the pulumi config get subcommand:

$ pulumi config get aws:region
us-west-2

To list all of a stack’s current settings, run pulumi config:

$ pulumi config
KEY                                        VALUE
aws:region                                 us-west-2
ahoy-pulumi:launchDarklyKey                [secret]

Finally, to remove a variable’s value altogether, use the pulumi config rm subcommand:

$ pulumi config rm aws:region

We’ve now covered the project-level machinery, so let’s dive further into core programming model concepts, beginning with the most critical program concept of all – resources.
