+# Magento Kubernetes components
+
+Install minikube. 
+
+Start minikube. And use docker env.
+
+```bash
+minikube start
+eval $(minikube docker-env)
+```
+
+Install helm (cluster should be run to set tiller). [Install guide](https://docs.helm.sh/using_helm/#installing-helm)
+
+
+## NFS server (optional)
+
+Configure your sources directory as export (/etc/exports) in the NFS server that runs on your host machine. This way containers can mount source code. This is a lot faster than a default VirtualBox shared folder mount. You only have to do this once, the NFS service will load /etc/exports at (re)boot.
+
+NOTE: The Minikube IP can be different after a minikube delete and minikube start command. Make sure that your NFS export contains the correct Minikube IP again.
+
+[More info](http://pietervogelaar.nl/minikube-nfs-mounts)
+
+### Mac OS X
+If you do not have python, install it using brew:
+```bash
+brew install python
+```
+echo "$(python -c 'import os,sys;print(os.path.realpath(".")')/sources -alldirs -mapall="$(id -u)":"$(id -g))" $(minikube ip)" | sudo tee -a /etc/exports && sudo nfsd restart
+Check if the entry is active by executing on your host machine:
+
+```bash
+showmount -e 127.0.0.1
+```
+
+This should output something like:
+
+```bash
+Exports list on 127.0.0.1:
+/Absolute/path/to/magento 192.168.99.100
+```
+
+There is also variable in values.yml which should be enabled
+
+## Run deployments
+
+Configuration values located in values.yaml
+
+To run all charts execute next command:
+
+```bash
+helm install --values values.yaml .
+```
+
+(temporary) Magento sources should be cloned to source path in current chart and in checkout subchart as well.
+
+DB password autogenerated in container, to check it list pods:
+```bash
+kubectl get pods
+```
+
+choose one of mysql pods end run bash in it:
+
+```bash
+kubectl exec -it release-1-some-mysql-pod bash
+```
+
+Observe env variables with prefix MYSQL_
+
+## Clean
+
+To delete releases run:
+```
+helm delete $(helm list -q)
+```
