* multi-cloud compatibility
To do so, we'll need to implement [[Kubernetes]].
== Ansible with Kubernetes ==
We will almost certainly leverage [[Ansible]] as an orchestration tool. In a recent blog post on ansible.com, Jeff Geerling (@geerlingguy) answers the question: "[https://www.ansible.com/blog/how-useful-is-ansible-in-a-cloud-native-kubernetes-environment How Useful is Ansible in a Cloud-native Kubernetes Environment?] The short answer is that Ansible can be used for:
# Container Build ([[Ansible-bender]])
# Cluster Management ([[Kubespray]])
# Application Lifecycle (Use Ansible to build Operators with the Operator SDK to handle deployment, upgrades, backups, etc.)
Here's more information about [[Ansible with Kubernetes]]
== At WikiMedia Foundation ==
We also want to leverage the work being done at WMF. See [[Automated deployment of MediaWiki]]
== Twelve-Factor App ==
One of the challenges, especially since it involves potential changes to MediaWiki itself, is the notion of "[https://12factor.net/ The Twelve-Factor App]" and how MediaWiki currently does not meet the criteria in one way or another. There's an open issue: [https://phabricator.wikimedia.org/T173955 Allow DefaultSettings.php be overridden by environment variables] that would help with the config aspect of things. The guys at Roots.io created an alternate WordPress system starting back in 2013 "[https://roots.io/twelve-factor-wordpress/ Twelve-Factor WordPress App]", inspired by an even older post [http://www.darrenmothersele.com/blog/2013/05/29/twelve-factor-drupal/ The Twelve-Factor Drupal Web App]. A more recent presentation on [https://docs.google.com/presentation/d/1AZIq628GEquvljmjSDAqvP0KkgkBWATWHWM39rat66c/edit#slide=id.p Twelve-Factor Drupal] was made at Drupal Camp Colorado in 2019.
== High-level outline ==
## Create service account at GitHub - to prevent access to private repos through Docker Hub
## Add automated builds and automated testing
# Create a [[Kubernetes Operator]] for MediaWiki.
# Add metrics with the [https://github.com/helm/charts/tree/master/stable/prometheus-operator helm chart prometheus-operator]
== Container Runtime ==[[Docker ]] (default in kublet <ref>https://github.com/kubernetes/community/blob/master/contributors/devel/sig-node/container-runtime-interface.md</ref>) is just one of many the container runtimes that can be used with Kubernetes. The others include containerd and CRI-O.
