Docker – Start-Process : A parameter cannot be found that matches parameter name ‘Command’

Are you ssh'ing in as the same user as typical?

Are you ssh'ing into the same machine you or on or to a remote one?

What OS are you running? Assuming *Nix...

Run whoami, groups and echo $PATH (individually of course).

If the binaries are not in the PATH variable it is clear why they are not being found.

You need to install the tools for them to be in the container, (if that is what you want). ADD and COPY can work but you need to make sure you install Everything needed. If you need specific tools and are build an image with a Dockerfile then one option is installing them into the image there. You can also set a USER parameter in the Dockerfile, you can also mount volumes.

The issue you're having with a duplicated node with the same name but different ID is explained here, probably a node that left the swarm and rejoined it, a manager restart...

If you want to remove the duplicated node and get rid of that ambigous warning, you may use the hash ID and not the name:

docker node rm 2keku0oj8zhsy6uyvyl4gd4d7

If you want to remove the other node named elk12, it seems that the node is a manager so you should proceed with caution as you may run into troubles if there are not enough managers to reach a consensus. If you feel it's safe to remove that manager node because you have enough nodes running as managers in your swarm, you should perform the following:

1. Demote the manager node (docker node demote). So that node is no longer a manager node and runs as a worker node.
2. Drain the worker node (docker node drain). The containers running in the elk2 would be moved to other worker nodes in the cluster.
3. Make the worker node leave the Swarm (docker swarm leave inside the elk2 node)
4. Remove the node (docker node rm ...)
