Hey @dimberman @kaxil @turbaszek -> I have almost working change where Kind Kubernetes cluster is created on the host side and it can be used to run the tests with Kubernetes. I nicely integrated it with breeze so that you can run:

breeze kind-cluster start -> will start the kind cluster

breeze kind-cluster deploy --force-build -> will deploy airflow to the cluster

and then you should be able to run tests. I just wanted to share it with you so that you can take a look. This can be very easily reused for the helm chart deployments (@dimbermann) and I think it's a better way of handling Kind Setup than relying in Github Action specific configuration from #8222 - because it can be run for local testing as well and it can be run on any CI (Travis/GA/Cloud Build. ....) . I updated the documentation including explanation how I imagine running the tests locally with breeze.

I am planning to complete it tomorrow - but please take a look in the meantime :).

It is based on the #8261 so only look at the latest commit.

@potiuk is there a reason we're still defaulting to such an old k8s? We should set it to at least 1.17 (unless that should be a separate PR).

@dimberman Old release? Version 1.14 is the latest version of the stable release channel on GKE. Version 1.15 is the latest version of the regular release channel. I don't think we need to use the latest possible version, but the most popular version.

The following Kubernetes versions are currently available for new clusters in Amazon EKS:

1.15.11
1.14.9
1.13.12
1.12.10

https://docs.aws.amazon.com/eks/latest/userguide/kubernetes-versions.html

You can use the newer version if you use GKE on AWS. However, this is a new service that was released yesterday.

No reason whatsoever. Just carried from the past. Right now it's as easy as modifying a few constants :)

@mik-laj - for now the deployment we have is kinda "abomination" - we will replace it with helm charts shortly - for now I know the Deployments we have won't work for higher versions of Kubernetes but I do not want to lose time trying to fix them since we are going to swap them with the helm charts.

Oh did not read that @jhtimmins - same for me.

Tests requiring Kubernetes Cluster are now moved out of the regular CI tests and moved to "kubernetes_tests" folder so that they can be run entirely on host without having the CI image built at all. They use production image to run the tests on KinD cluster and we add tooling to start/stop/deploy the application to the KinD cluster automatically - for both CI testing and local development. This is a pre-requisite to convert the tests to convert the tests to use the official Helm Chart and Docker images or Apache Airflow. It closes #8782 (cherry picked from commit ff5dccc)

)

We upgraded to v2 in apache#8265 for other places in `.github/workflows/ci.yml`. This was left, so fixing it.
