A Docker Container to run to deploy the MariaDB Operator
This project is designed to create a containerised Kubernetes infrastructure on DigitalOcean, and deploy the following using automation:
- MariaDB Kubernetes Operator
- Photo App test application
For this demonstration to work, you will require various third party accounts.
Nothing in this demonstration is designed to be used in production and this is not supplied, supported or endorsed by MariaDB.
Please note the free $200 credit is enough to run this demonstration, however, if you do not decommission your services, or you use more than the free credit you will be liable for the cost.
You require a certain level of technical knowledge to complete this, as you are required to install some tools to your computer.
The demonstration is designed to run within a Docker Environment.
You will require FREE accounts for:
Digital Ocean supports Single Sign On (SSO) using your GitHub account. SSO allows easy navigation between the services and allows you to link the accounts together.
It is important to create your Github account before creating the other accounts.
Hopefully you have already created the Third Party Accounts required.
You can now fork the required repositories.
Copy the .env.example file and add your API KEY from Digital Ocean.
Once you have forked the repositories, you need to build the dockerfile and run the created container.
docker compose build --no-cache
docker compose up -d
To make it easy, there is a make script to set up your kubernetes environment. Connect in to your Docker Container.
make init-demo
make plan-demo
make apply-demo
Once your Kubernetes Cluster is built you can run the following commands:
make initialise-helm
make prepare-operator
You need to wait about 30 seconds for the operator to become available and then you can:
make install-operator
After three minutes you can check the pods are available: kubectl get pods
You should now have a fully running Kubernetes Cluster with a MariaDB database environment. To install the application run:
make install-photo
After a few minutes you can get the services information and connect:
kubectl get svc
Find the maxscale-gui IP and connect to it via the IP address:8989 --> mariadb-operator / MaxScale11!
You will also find the service IP address for the Application.
The destroy command will delete the infrastructure. This is important, if you have finished using it, to stop getting charged. But please note, some resources such as Load Balancers and Storage will remain. Clearly, do not run this until you have finished.
make destroy-demo
If you are running the destroy command, it will ask you to confirm by typing yes at the prompt.
