MariaDB operator

This operator is based on shell-operator. Goal of this operator is easily setup databases and users by using declaritive yaml configuration files.

How to install on kubernetes

• helm install mariadb deploy/mariadb

How to contribute

The development environment installs k0s on vagrant and exports a kubeconfig file so that access to the kubernetes cluster from host machine is possible.

Please check the Makefile for further details.

Prerequisite

• vagrant
• vagrant-libvirt plugin
• vagrant-sshfs plugin

How to setup the environment

1. Modify your Vagrantfile so that it fits to your need (e.x. cpu, memory)
2. Kickoff a virtual machine with vagrant up
3. Set environment variable for kubectl with export KUBECONFIG=kubeconf.conf

Either run vagrant ssh -- make -C /vagrant build test-latest to get a container without dev-tools running or follow the next section to access the dev container.

Working within the dev container

• Build dev container by running make -C hack build deploy.
• Insert on top of ~/.ssh/config the following line Include path-to-your-repo/hack/ssh_config.
• Sync with rsync make -C hack rsync-push or make -C hack rsync-pull.
• Open vs code via ssh make -C hack open-vscode
• Run operator manually kubectl exec -ti deployments/mariadb -- bash -c '/shell-operator 2>&1 | jq -r .msg'

Helper commands to troubleshoot issues

• kubectl exec -ti deployments/mariadb -- bash -c 'mysql -h 127.0.0.1 -u root --password=$MARIADB_ROOT_PASSWORD -e "SELECT Host, User, Password FROM mysql.user;"'
• kubectl exec -ti deployments/mariadb -- bash -c 'mysql -h 127.0.0.1 -u root --password=$MARIADB_ROOT_PASSWORD -e "SHOW DATABASES"'

Enjoy!
