8000. Through this port, the Edge Agent can poll the Portainer instance, connect to Portainer, see when it is required, then initiate a tunnel or receive configuration updates. Without port
8000exposed on the Portainer Server instance, you cannot access the Edge endpoint. If you already deployed Portainer without this port open, you will need to redeploy with port
8000exposed alongside the port used to access Portainer. Using the CLI flag
--tunnel-portyou can set a different port if
8000is already in use. For more information see CLI options.
