From the swarm page, there is no way to delete nodes that have been removed from the swarm

From the swarm page, there is no way to delete nodes that have been removed from the swarm

Steps to reproduce the issue:

1. From a worker node, type docker swarm leave.
2. Refresh Swarm tab in portainer (1.15.2 in this case). Note that Status is Down.
3. Attempt to remove down node. I migrated some things, and wanted the node deleted.

Any other info e.g. Why do you consider this to be a bug? What did you expect to happen instead?

Technical details:

• Portainer version: 1.15.2
• Target Docker version (the host/cluster you manage): 17.09.0-ce
• Platform (windows/linux): Linux
• Command used to start Portainer (docker run -p 9000:9000 portainer/portainer):
• Target Swarm version (if applicable):
• Browser:

This of course is accomplished by docker node rm
If I do this manually, it is removed from portainer which I guess is an okay workaround.

The docker swarm leave command only exits the worker from the swarm, you also need run “docker node rm <node>” on a manager node to remove the old node from the list. https://docs.docker.com/engine/swarm/manage-nodes/#leave-the-swarm Rgds, Neil Cresswell On 20/12/2017, at 7:48 AM, Kirby Kuehl <notifications@github.com<mailto:notifications@github.com>> wrote: From the swarm page, there is no way to delete nodes that have been removed from the swarm Steps to reproduce the issue: 1.

From what I can see in the Docker API, only the LeaveSwarm operation exists: https://docs.docker.com/engine/api/v1.30/#operation/SwarmLeave

Not sure how the Docker CLI handles the docker node rm part, we should investigate this.

EDIT:

This should be done by using the LeaveSwarm and NodeDelete operations:

• https://docs.docker.com/engine/api/v1.30/#operation/SwarmLeave
• https://docs.docker.com/engine/api/v1.30/#operation/NodeDelete

AFAIK, portainer doesn't yet support swarm management
If swarm leave/rm is implemented, i think swarm init/join should be too, no ?

[deviantony]

@WTFKr0 yeap, as a part of another feature request probably.
