### Running the image
### Requirements
```
docker 20.10+
```
To run this image, we have to do the following:
```
docker build -t mariadb-galera:latest .
docker-compose up
```
At this time only connections from localhost are allowed.
To connect to the container from another host/network, we have to do the following:
```
docker exec -it mariadb-galera-docker_mariadb-galera_1 /bin/bash
mysql --user root --socket /opt/canonical/mariadb-galera/mariadb/tmp/mysql.sock
CREATE USER 'root'@'%';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
```
### Using the image in a Microk8s cluster
```
$ microk8s enable registry
$ docker images
-> Find the tag for the mariadb-galera image, built in the previous step
$ docker tag {image_id} localhost:32000/mariadb-galera:latest
$ docker push localhost:32000/mariadb-galera:latest
```
Useful commands, when using the MicroK8S local registry:
- Get the list of images pushed to the registry
http://localhost:32000/v2/_catalog?n=10
- Get a list of versions for the mariadb galera image
http://localhost:32000/v2/mariadb-galera/tags/list?n=10
