In the unfortunate event that the container won't start, for example if connection to the remote sources failed, try the following fixes.
- Docker container won't start.
Rebuild the container and start again.
// delete the volume
docker-compose -f ./keycloak-docker-assembly/docker/docker-compose-dev.yml down -v
// rebuild and start the container
docker-compose -f ./keycloak-docker-assembly/docker/docker-compose-dev.yml up --build
