Configure environment variables

Environment variables can be configured in the radixconfig.yaml. Additionally Radix will add some environment variables prefixed with RADIX_ and RADIXOPERATOR_ - these prefixes should not be used for environment variables.

Environment variables can be overridden in the Radix Console, excluding those marked with the RADIX_ and RADIXOPERATOR_ prefix.

The value of an environment variable, changed to a new value in the Radix Console, will use this new value for all new deployments. To revert to the original value - edit it again, changing to its original value, specified in the radixconfig.yaml.

Overriding environment variables in the Radix Console

• Navigate to the application component or job page
• Click the Edit button
• Change one or more variables
• Click the Apply button

After a few seconds the value of the overridden environment variables will be shown in the table.

tip

Note that changes made in the Radix Console will not be applied to currently running replicas or jobs, meaning these will have to be restarted for the changes to take effect.

To apply changed environment variables:

• go to component replicas - restart the component
• go to jobs - start new jobs

In the Environment variables table, the column marked Original is used to show the original value of all modified variables.

Example

• Environment variables configured in radixconfig.yaml.

  variables:
    VAR1: "val1"
    VAR2: "val2"
    VAR3: "" # leaving a variable empty is a valid option

• Environment variables shown in the Radix Console. Variables VAR1 and VAR3 has been changed.
