Run the following command to remove a component:
devspace remove deployment [deployment-name]
Before actually removing the component, DevSpace CLI will ask you the following question:
? Do you want to delete all deployment resources deployed? [Use arrows to move, type to filter] > yes no
Deleting all resources deployed to Kubernetes before removing a component is very useful, so you do not end up with untracked resources which waste computing resources although they are not needed anymore.
