This code block is a stage written in the syntax of a Jenkins pipeline. Here's a step-by-step breakdown of what it does:

1. Stage Name:
   The process is encapsulated in a stage named Update Config Repository.

2. Container Context:

   • The code appears to be using the Kubernetes plugin for Jenkins, where actions can be executed inside containers. The first container used is indicated with container('git').

3. configRepo Function:
   Inside this container:

   • A presumably custom-defined function configRepo(config) is invoked, which seems to handle actions for updating or verifying a configuration repository based on the config variable. The result of this function is assigned to the variable tf.

4. Logging:
   The result of the configRepo(config) function (tf) is printed to the pipeline's log using println.

5. Conditional Check and Fallback:

   • The if (!tf) condition checks whether the variable tf evaluates to false (indicating the repository update or verification probably failed).
   • If tf is false, the code performs additional steps.

6. Fallback Actions in Different Container:

   • The pipeline switches context to another container, namely container('ubi8').
   • Inside this container, it uses the withCredentials block to inject a secret credential. Specifically:
     • A credential identified by argocd-ocp4np-token is loaded as an environment variable named ARGO_TOKEN.

7. Fallback Action - argoRestart:

   • A presumably custom-defined function argoRestart(config) is invoked. This function is likely responsible for restarting or reconfiguring something using ArgoCD with the assistance of the previously loaded credentials.

Summary:

This stage attempts to update or verify a configuration repository by calling configRepo(config) in a git container. If this operation fails (determined by tf being false), it switches to a fallback strategy:

1. Executes actions in a ubi8 container.
2. Injects an ArgoCD token as credentials.
3. Runs the argoRestart(config) function, likely to perform ArgoCD-related operations, such as restarting or reconfiguring applications.

This code integrates continuous deployment/development tools, container context switching, and credential management in Jenkins pipelines.
