Thank you for your contribution, @vanny96!

Since tyk-gateway is a component chart used by several other charts (tyk-stack, tyk-control-plane, tyk-data-plane, and tyk-oss), we need to ensure that the values.yaml files for each of these charts are updated with the latest configuration you've added related to extraContainers.

Would you mind updating the values.yaml files for the charts I mentioned? This will help maintain consistency across the charts. Feel free to tag me if you have any questions Thanks again!

Hey, sure thing, I'll get to it either later today or tomorrow!

hi @vanny96, I believe I expressed myself incorrectly. What I actually meant was that I wanted to add the newly introduced extraContainers configuration to the tyk-gateway section in the values.yaml file of each chart.

For example, at the moment, if we use tyk-stack, we can't configure extraContainers through values.yaml file explicitly unless I know the existence of such a configuration.
Can you please update values.yalm file of the charts (tyk-stack, tyk-control-plane, tyk-data-plane, and tyk-oss) so that values.yalm file of these (for instance, tyk-stack's file, here) include the changes you've added? Let me know if you have any questions. The PR looks great, and i'd like to proceed with merging.

Huh, I just interpreted it wrong, you were super clear, I'll get to it and at this point I might add it for everything 😅

@buraksekili I think now it should be good! Can you double check it?
