Using Kubernetes for development?
Using Kubernetes for development?
I'd love to hear some stories about how you or your organization is using Kubernetes for development! My team is experimenting with using it because our "platform" is getting into the territory of too large to run or manage on a single developer machine. We've previously used Docker Compose to enable starting things up locally, but that started getting complicated.
The approach we're trying now is to have a Helm chart to deploy the entire platform to a k8s namespace unique to each developer and then using Telepresence to connect a developer's laptop to the cluster and allow them to run specific services they're working on locally.
This seems to be working well, but now I'm finding myself concerned with resource utilization in the cluster as devs don't remember to uninstall or scale down their workloads when they're not active any more, leading to inflation of the cluster size.
Would love to hear some stories from others!

I have found with individual dev environments that they cause many issues with outdated service versions. If you are going this route, I would use ScheduledScaler to shut down dev resources after hours.
I have found much more success with PR deployments - every PR gets deployed and wired up to a PR environment which has a full copy of dev and a copy of each PR which runs for 8 hours after the PR is built (I switch out the deploy for a job). Not every service maps well to this model, but it's a good 95% solution in my experience.
Yeah I agree, but for us this would mean like 30 containers. We've tried several times to have some kind of flexible setup where devs could choose which parts to run, but that got complicated with all the various permutations of the containers and devs needing different setups in different situations.
It just became a lot to try and manage/support
