How to customize a cluster image in GITA?

Customizing a cluster image in GITA allows you to choose the version of the probes used, use images from your own registry (private, internal, or with specific cluster permissions), and have full control over the configurations and versions used in your containers, ensuring compatibility and security according to your needs.

1. Access your Cluster Interface in Gita:

   Explanation about the displayed versions:

   For each cluster component, two version pieces of information are displayed:

   • Current Version: Indicates the image version currently in use in your cluster.
   • Latest Version: Indicates the latest version available for that component.

   If the current version is different from the latest, it will usually be highlighted in red, indicating that an update is available. Keeping images up to date is important to ensure access to bug fixes, security improvements, and new features.

5. To add a custom image, click on the Advanced tab:

10. For the image changes to be effectively applied to the cluster, you need to run, in the terminal, the commands shown on the screen, following the presented order. Use the copy button next to each command to make the process easier: copy, paste, and run each command in the terminal, one at a time, until you complete the indicated steps. After completing these steps, the new images will be applied to the cluster:
