Override default configuration

A number of values can be set in the SUSE Observability Helm chart. For example, it’s possible to customize the tolerations and nodeSelectors for each of the components. You can also add customized configuration and include environment variables

Custom configuration for SUSE Observability api

For the SUSE Observability api service, custom configuration can be dropped directly into the Helm chart. This is the advised way to override the default configuration that SUSE Observability ships with and is especially convenient for customizing authentication. Configuration set in this way will be available to the SUSE Observability configuration file in HOCON format.

For example, you can set a custom "forgot password link" for the SUSE Observability login page:

  • values.yaml

stackstate:
  components:
    api:
      config: |
        stackstate.api.authentication.forgotPasswordLink =
        "https://www.stackstate.com/forgotPassword.html"

Note that custom configuration set here will be overridden by environment variables.

Environment variables

The configuration for all of the SUSE Observability services (receiver, k2es-*, correlation and api) can be customized using environment variables. Environment variables are specified in the values.yaml file and can be either secret (such as passwords) or open (for normal values). To convert a configuration item to an environment variable name, replace . with and add the prefix CONFIG_FORCE.

# configuration item
stackstate.api.authentication.forgotPasswordLink

# environment variable name
CONFIG_FORCE_stackstate_api_authentication_forgotPasswordLink

For example, you can set a custom "forgot password link" for the SUSE Observability login page:

  • values.yaml

stackstate:
  components:
    api:
      extraEnv:
        # The value for open env vars is defined on the deployment
        open:
          CONFIG_FORCE_stackstate_api_authentication_forgotPasswordLink: "https://www.stackstate.com/forgotPassword.html"
        # The value for secret env vars is defined in a secret and referenced from the deployment
        secret:
          CONFIG_FORCE_stackstate_authentication_adminPassword: "d8e8fca2dc0f896fd7cb4cb0031ba249"

For the SUSE Observability api service, environment variables will override custom configuration set using config.
