Environment variables#
Semaphore uses environment variables for configuration. In practice, these variables are typically set as Helm values and 1Password/Vault secrets that are injected into the container as environment variables. See the Phalanx documentation for Semaphore for more information on the Phalanx-specific configurations.
- SAFIR_NAME#
(string, default: “semaphore”) The name of the application. This is used in the metadata endpoint and the application’s URL path prefix.
- SAFIR_PROFILE#
(string enum: “production” [default], “development”) The application run profile. Use production to enable JSON structured logging.
- SAFIR_LOG_LEVEL#
(string enum: “debug”, “info” [default], “warning”, “error”, “critical”) The application log level.
- SEMAPHORE_ENABLE_GITHUB_APP#
(boolean, default: “true”) Whether to enable the Semaphore GitHub App. If true, the app will be enabled and the
SEMAPHORE_GITHUB_*variables must be set. See Configuring the GitHub App for more information.
- SEMAPHORE_GITHUB_APP_ID#
(secret string) The GitHub App ID for the Semaphore GitHub App. Can be an empty string if the app is not configured. See Create the app and secrets for more information.
- SEMAPHORE_GITHUB_APP_PRIVATE_KEY#
(secret string) The GitHub App private key for the Semaphore GitHub App. Can be an empty string if the app is not configured. See Create the app and secrets for more information.
- SEMAPHORE_GITHUB_WEBHOOK_SECRET#
(secret string) The GitHub webhook secret for the Semaphore GitHub App. Can be an empty string if the app is not configured. See Create the app and secrets for more information.
- SEMAPHORE_PHALANX_ENV#
(string) The name of Phalanx environment this Semaphore installation is running in (e.g.
idfprod). This configuration aids in determining which broadcast messages from a shared GitHub repository to index, based on theenvYAML/markdown front-matter keyword. For a list of environments, see https://phalanx.lsst.io/environments/index.html.
