Support imagePullPolicy via label.

[mikesimos]

Would kompose.image-pull-policy be a good candidate name for this label?

[jvitor83]

The only change i make was the label name, that i use: kompose.service.image-pull-policy

Hi @jvitor83 ! Sorry just saw that. I was waiting for some confirmation/ guidelines for this issue from the project maintainers following contributing guidelines here. I already have some work for own use on this here awaiting to be PRed. Would you mind rebasing your contribution on top of this? Thanks!
The naming of the label is indeed a concern, but since imagePullPolicy isn't a docker-compose service directive, I wouldn't use the kompose.service prefix. I was rather inclined towards something like kubernetes. prefix for kubernetes specific customizations. This feature focuses on very specific use cases were imagePullPolicy Never needs to be specified (ie. industrial air-gapped environments, etc). Not sure if this (check imagePullPolicy) is helpful for you.

@cdrage @hangyan, I m creating a PR for comments/guidelines? Thanks!

[jvitor83]

@mikesimos closing my PR since your appear to do the same (only with different label).
