Wordpress OKD / Openshift implementation

This project is trying to implement an easy and secure way for Wordpress on Openshift / OKD

The goals were:

  • Use reliable base images (UBI8 & CentOS)
  • make upgrades easy
  • make it easy to understand (it's also part of an Openshift Workshop)
  • make it customizable in wordpress: plug-ins, themes, ...
  • updates of the core wordpress should require a container rebuild
  • container builds via openshift docker builds

Implement a secure clean wordpress installation

Always inspect all the yaml files first:

  • look for object names
  • ConfigMap and Secret values
  • play special attention to the image paths!

make wordpress container

First install the bitbucket pull secret for the BRZ repo: oc apply -f Secret_bitbucket-pull-ssh.yaml

  • download wordpress curl -L -o wordpress-container/wordpress.tar.gz https://wordpress.org/latest.tar.gz
  • run a docker build in the ./wordpress-container/ dir or
  • oc apply -f wordpress-container/ImageStream_wordpress-container.yaml
  • oc apply -f wordpress-container/BuildConfig_wordpress-container.yaml

get a suitable mariadb container

  • The easy way: oc import-image quay.io/centos7/mariadb-103-centos7:latest --confirm

  • The complete way:

      ```shell
  podman pull quay.io/centos7/mariadb-103-centos7:latest
  oc create imagestream mariadb-103-centos7
  podman tag quay.io/centos7/mariadb-103-centos7:latest default-route-openshift-image-registry.apps.fangorn.pfpk.pro/brz-ws-paas/mariadb-103-centos7:latest
  podman login -u $(oc whoami) -p $(oc whoami -t) default-route-openshift-image-registry.apps.fangorn.pfpk.pro 
  ```

create Openshift / OKD objects

oc apply -f openshift/

Enter your install

  • Look to the Route element
  • Go for http first, https and Wordpress is not so easy ;-)

Kustomize

If you want to deliver the container with ArgoCD, simply copy the directory kustomize to your delivery repo. Now you can deliver and deploy with ArgoCD.
