In this final unit we’ll learn how to use Docker command line to pull the image for the latest FMR version, start a running container and begin working with FMR.
Using Docker command line, execute the following commands:
Pull the latest FMR image from Docker Hub:
docker pull metadatatechnology/fmr-mysql:latest
This could take a few minutes while layers that make up the image are downloaded from Docker Hub.
Create a container called ‘fmr’:
docker container create --name fmr --publish 8080:8080 metadatatechnology/fmr-mysql:latest
--publish 8080:8080 tells Docker to export the container’s internal port 8080 to the host machine using the same port number. When we later come to work with the running FMR, we’ll see that the URL references port 8080.
Start the container:
docker start fmr
The container will take between one and two minutes to start.
Using a web browser, navigate to: http://localhost:8080/
The FMR web user interface will appear when start-up is complete
The container can be stopped using the following command:
docker stop fmr
In the standard Docker image, FMR is configured with a single superuser account called ‘root’.
Logging-in as this account allows the user to:
The default credentials are:
It’s good practice to change the default root password to something more secure inless the container is being used for personal or non-critical testing. Do this from the Security menu choosing ‘Root User Account’.
Any metadata added to the registry will be persisted in the container.
Thus FMR containers can be stopped and restarted as required without loosing any work.
Deleting a container will also delete any structural metadata held in its registry.
FMR can additionally use an external Microsoft Active Directory or Open LDAP directory service for user authentication allowing other user accounts in addition to the default ‘root’ account.
The procedure for is outside of the scope of this module.
