Kubernetes custom resource definitions help the extend the capabilities of the k8s. There is a large amount of k8s CRDs published under Open Source licenses. This git repository list all available Open Source Kubernetes (k8s) CRDs. https://github.com/gnudeep/k8s-crd-repo/blob/master/README.md gnudeep/k8s-crd-repo Contribute to gnudeep/k8s-crd-repo development by creating an account on GitHub.github

This short note describes how to deploy Envoy proxy in K8s to proxy MySQL server. Take a checkout of the following git repo. https://github.com/gnudeep/k8s-envoy.git Build the Envoy proxy Docker image using the Docker file in the repo. This Docker image burns the static envoy configuration into the docker image. docker build -t deependra/envoymysql . docker push deependra/envoymysql After finishing the docker push, deploy k8s artifacts using kubectl command.
