Easy way to update the container image name about kustomize HOT 13 CLOSED

Maybe this could mostly be accomplished by allowing the name field to be a regular expression?

The idea in #122 can help this. If kustomize provides to way to declare a user defined transformation and use that, this transformation can will be applied during kustomize build. To patch multiple objects with one patch, you only need to provide a proper transformer.

I love this idea/feature as well. I work on mono-repo project where we manage kubernetes spec for 30 microservice. We have templated everything in spec so that adding new service is a breeze. Templating logic is so complicated we have decided to move away from that approach and start evaluating tools like Kompose. Kompose doesn't fit for the project structure as the selector for deployment works by metadata->name and I will end up overlays for each service and lots of duplication

Does seem to make sense to be able to target resources with something other than name, label perhaps.

The README relates kustomize to sed it's like sed, in that it emits editted text., which is a great comparison, and is how i want it to work, but unless i'm missing something I can't use arbitrary values to target things for overlays? Name, label, or even just type would be great. I'd like to be as generic as possible.

Regardless of the patches or transformation. The original request is to ask an easy way to update the container image name wherever it is used.

@Liujingfang1 actually, I was concerned about transforming/sharing multiple pod values, not just the container name.

@bickfordb What pod values you need to update? Can you give an example?

I think there are 2 issues here:

• Write patches that can match label / names
• Support a simple way to update images without a patch

This can be solved by #122

Support a simple way to update images without a patch

This is supported by imageTags. See the imageTags demo

@Liujingfang1 are you particularly opposed to allowing patches to match on a label based selector?

@bickfordb This issue was closed because of it's name and the introduction of set imageTag command.

The notion of applying patches guided by a label based selection could certainly be opened as a new issue.

As could the If you have time, please look at the conversation in #300 (less so the one in #169) and feel free to comment. It's closely related so some of what you mentioned above w/r (outside the scope of changing only the image tag).
