Guía básica de Docker

docker stop portainer

docker rm portainer

docker image ls | grep portainer

Make sure the containter is stopped and removed, then take that ID from above, and:

docker image rm xxxxxxxxxxxx

Do that for each image listed for portainer. DO NOT DELETE portainer_data volume unless you want to TOTALLY start over. You will LOSE your configuration data if you do that.

Now do a:

docker pull portainer/portainer

Then create and start the replacement container using your old data:

docker run -d -p 8000:8000 -p 9000:9000 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer
