Introduction
In this article we will learn how to to setup wordpress in kubernetes cluster using helm
Helm: Helm is a tool for managing Kubernetes charts. Charts are packages of pre-configured Kubernetes resources.
- Let’s Begin deploying wordpress using helm in kubernetes , if you are new to helm then download and initialize helm as follows
root@kube-master:# helm init root@kube-master:# kubectl create serviceaccount --namespace kube-system tiller root@kube-master:# kubectl create clusterrolebinding tiller-cluster-rule \ --clusterrole=cluster-admin --serviceaccount=kube-system:tiller root@kube-master:# kubectl patch deploy --namespace kube-system tiller-deploy \ -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'
- Make sure the title-deploy pod is up and running
root@kube-master:/home/ansible# kubectl get pods -n kube-system NAME READY STATUS RESTARTS AGE coredns-78fcdf6894-jvmlb 1/1 Running 0 1h coredns-78fcdf6894-xstbn 1/1 Running 0 1h etcd-kube-master 1/1 Running 0 1h kube-apiserver-kube-master 1/1 Running 0 1h kube-controller-manager-kube-master 1/1 Running 0 1h kube-flannel-ds-5gzn9 1/1 Running 0 1h kube-flannel-ds-tlc8j 1/1 Running 0 1h kube-proxy-kl4fg 1/1 Running 0 1h kube-proxy-krt6n 1/1 Running 0 1h kube-scheduler-kube-master 1/1 Running 0 1h <mark>tiller-deploy-85744d9bfb-wh98g 1/1 Running 0 1h </mark>
- Once titler pod is up and running, deploying wordpress uses bitnami docker images, for this we need to go and create PersistentVolume and PersistentVolumeClaim
- Define the PersistentVolume for mariadb-pv where the mariadb data to be stored. The hostPath tells the mysql directory is in /bitnami/mariadb location
