KIND development workflow

1. Create your kind cluster (suit yourself https://kind.sigs.k8s.io/docs/user/configuration/)

cat <<EOF | kind create cluster --config=-
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane

Networking scenarios [Linux Only]

KIND runs Kubernetes cluster in Docker, and leverages Docker networking for all the network features: port mapping, IPv6, containers connectivity, etc.

Docker Networking

KIND uses a docker user defined network.

It creates a bridge named kind

Gem Install Dockerfile Hack

If you're hacking on your Gemfile and using Docker, you know the pain of having the bundle install command run after you've added or removed a gem. Using docker-compose you could mount a volume and stage your gems there, but this adds additional complexity and doesn't always really solve the problem.

Enter this imperfect solution:

What if we installed every gem into it's own Docker layer which would be happily cached for us?

gem-inject-docker does just that. It takes the list of gems used by your app via bundle list and transforms it into a list of RUN gem install <your gem> -v <gem version> statements and injects them into the Dockerfile at a point of your choosing.

Perform Keycloak Export and Import on Kubernetes

• Setup Keycloak in non-HA mode (replica 1)
• Disable UserFederation
• You might have to increase the resource limits to avoid that pod beeing killed by memory or CPU limits

See Keycloak Documentation for more details.
