Configure rhacs github oidc auth
Create github actions pipeline

Red Hat Advanced Cluster Security can be easily integrated into an existing GitHub actions pipeline through the existing Stackrox suite of open source actions. The roxctl cli can be used to scan images for vulnerabilities or common misconfigurations.

Configure rhacs github oidc auth

Red Hat Advanced Cluster Security for Kubernetes (RHACS) provides the ability to configure short-lived access to the user interface and API calls.

You can configure this by exchanging OpenID Connect (OIDC) identity tokens for a RHACS-issued token.

We recommend this especially for Continuous Integration (CI) usage, where short-lived access is preferable over long-lived API tokens.

Create github actions pipeline

An example pipeline is included below and in this repository.
