Specify No/Minimum Plugin Version

[davmillar]

Is your feature request related to a problem? Please describe

We routinely run into problems where we want to use the Helm charts to update Jenkins, but the configuration for plugins contains conflicts and we need to debug it on the fly. For example, our latest update attempt yielded errors like this:

Plugin git:5.7.0 depends on credentials:1405.vb_cda_74a_f8974, but there is an older version defined on the top level - credentials:1393.v6017143c1763,

I'm not sure if I missed this feature and it already exists, but it would be nice if we could specify that we want to install a certain minimum version -- e.g. credentials no less than 1393.v6017143c1763, but allow the deployment to install the required version needed for other plugins to run.

Describe the solution you'd like

Maybe something like credentials:>=1393.v6017143c1763 or credentials:^1393.v6017143c1763.

Describe alternatives you've considered

In the meantime I've removed credentials from our config so it uses whichever is suitable for the plugins depending on it.

Additional context

I've inherited this process/system with little documentation to work from, so I am also open to advice on why this should not be a feature and what I should be doing instead. :)

Its recommended to build your own image and not rely on the base versions built-in to the helm chart:

https://github.com/jenkinsci/helm-charts/tree/main/charts/jenkins#consider-using-a-custom-image

Then you can use something like renovate or jenkins-plugin-cli to send pull requests to update your plugin versions
