You can create and manage your pods via the DC/OS CLI or via the /v2/pods/
endpoint of the Marathon API.
Using the Pods CLI
The following commands are available in the pods CLI:
dcos marathon pod add [<pod-resource>]
dcos marathon pod list [--json]
dcos marathon pod remove [--force] <pod-id>
dcos marathon pod show <pod-id>
dcos marathon pod update [--force] <pod-id>
Add a Pod
To add a pod, first create a JSON pod definition. Then, run the following command:
dcos marathon pod add <pod-json-file>
List Pods
List pods and the number of containers they have with the following command:
dcos marathon pod list
Remove a Pod
Remove a pod with the following command:
dcos marathon pod remove <pod-id>
If the pod is currently deploying, you will not be able to remove the pod. To remove the pod anyway, run the command with the --force
flag.
Show Pod JSON
To see the pod definition, run the following command:
dcos marathon pod show <pod-id>
You can use the show
command to read data about the pod programmatically.
Update Pod
To update a pod, first modify the JSON definition for the pod, then run the following command:
dcos marathon pod update <pod-id> < <new-pod-definition>
If the pod is currently deploying, you will not be able to update the pod. To update the pod anyway, run the command with the --force
flag.
