This presentation will discuss how we use Docker to improve our development and deployment of WordPress sites. The presentation describes how themes and plugins can be developed locally and then packaged into a Docker container. A Jenkins pipeline is used with Git to automatically run a build and deploy the new WordPress container onto a test server where automated Selenium scripts are executed. Based on the results of the tests the container is tagged as a production candidate. A deployment pipeline is then used to execute a Blue-Green deployment on the latest update to production. Once the deployment is proven to work through automated testing the router is switched to the new deployment. The overall process helps reduce the risk of production updates to WordPress, themes, and plugins as well as reduce security concerns caused by randomly installing plugins by users. The presentation will also discuss strategies for running a WordPress database both outside and inside of a Docker container. It will discuss the pros and cons of each approach.
