Connect more Docker hosts (agent / endpoints)

The local Docker host is connected from the start. Add more hosts in Containly under Endpoints, Add endpoint; "Show instructions" walks you through each way. The free tier allows 2 hosts (the local one plus one more), Pro allows any number.

Which way fits?

• Agent: the easiest way for hosts behind NAT or without open ports. The small containly-agent container dials out to Containly over WSS. Containly shows a one-time token and a ready-to-paste docker run command or a docker-compose.yml; the token is shown only once.
• SSH: for hosts you reach over SSH. The user must be allowed to use Docker (docker group or root). Stack deployments need key authentication instead of a password.
• TCP with TLS: for a Docker daemon on port 2376 with client certificates. Never use port 2375 without TLS.

The agent stays on "Waiting for the agent to connect"

• Check the agent logs on the target host.
• The agent must be able to reach your Containly address. If Containly runs behind a reverse proxy, the proxy has to pass WebSocket connections.
• The one-time token works only once. If you used it already, add the endpoint again.

"Endpoint limit reached"

The free tier allows 2 endpoints, the local host included. A Pro licence removes the limit.
