Magnum (Container Infrastructure Management service)

Magnum is an OpenStack API service developed by the OpenStack Containers Team making container orchestration engines such as Docker Swarm, Kubernetes, and Apache Mesos available as first class resources in OpenStack. Magnum uses Heat to orchestrate an OS image which contains Docker and Kubernetes and runs that image in either virtual machines or bare metal in a cluster configuration.

NOTE: The os used here is an instance of org.openstack4j.api.OSClient.OSClientV3.

Baymodel

Baymodel acts as a template that defines options such as the container orchestration engine, keypair and image for use when Magnum is creating Bay using the given Baymodel.

List baymodels

List<? extends Baymodel> res = os.magnum().listBaymodels();

Creating a baymodel

Baymodel res = os.magnum().createBaymodel(baymodel);

Delete a baymodel

Baymodel res = os.magnum().deleteBaymodel(baymodelId);

Show a baymodel

Baymodel res = os.magnum().showBaymodel(baymodelId);

Update a baymodel

Baymodel res = os.magnum().updateBaymodel(baymodelId, ops);

Bay

List bays

List<? extends Bay> res = os.magnum().listBays();

Create a bay

Bay res = os.magnum().createBay(bay);

Delete a bay

ActionResponse res = os.magnum().deleteBay(bayId);

Show a bay

Bay res = os.magnum().showBay(baymodelId);

Container

List containers

List<? extends Container> res = os.magnum().showBay(baymodelId);

Create a container

Container res = os.magnum().createContainer(container);

Delete a container

ActionResponse res = os.magnum().deleteContainer(uuid);

Get logs of a container

String res = os.magnum().getContainerLogs(id);

Start a container

Container res = os.magnum().startContainer(id);

Stop a container

Container res = os.magnum().stopContainer(id);

Reboot a container

Container res = os.magnum().rebootContainer(id);

Pause a container

Container res = os.magnum().pauseContainer(id);

Unpause a container

Container res = os.magnum().unpauseContainer(id);

Execute a command in a container

String res = os.magnum().execCmdInContainer(id, cmd);

Show a container

Container res = os.magnum().showContainer(id);
