alpine ping image repository should be present in values

[vtmocanu]

alpine ping image from here:

https://github.com/cloudnative-pg/charts/blob/main/charts/cluster/templates/tests/ping.yaml#L19

should be present in values so we can override the repository (& imagepull secret)

Thank you for this awesome product (CNPG)!

We can just replace it with the same image as the database as it also has psql and that's all it needs.

Hi, @WladyX. I'm Dosu, and I'm helping the charts team manage their backlog. I'm marking this issue as stale.

Issue Summary

• You suggested adding the Alpine ping image to the values file for better deployment customization.
• @itay-grudev proposed using the existing database image with psql instead, which could simplify the solution.
• The issue remains unresolved as of now.

Next Steps

• Please let us know if this issue is still relevant to the latest version of the charts repository. If so, you can keep the discussion open by commenting on the issue.
• Otherwise, the issue will be automatically closed in 7 days.

Thank you for your understanding and contribution!

This is causing us to have an SBOM fail. We must be able to override the repository in an air-gapped env. We do not even use this but it is flagged and causing issues.
