Arango Pod Uses Incorrect Image Hash

Problem

A cluster health-check returns a RED status with the following arango pod error:

Cause

Sometimes after a Kubernetes failure, the arango-operator assigns an incorrect wrong image tag or wrong image hash to the arango pods.

Use the describe command to determine the image hash that does not exist in the registry.

Verify that the registry does not have that particular image hash. The following output displays the image hash that exists in the registry.

Solution

Perform the following steps:

1. Restart the arango-operator.

2. Restart the pods that are stuck.
