Socket proxy fails

[truthsword]

Ask a Question!

I'm using the following docker compose file to launch Portainer using a socket-proxy:

services:
  portainer:
    image: portainer/portainer-ee:latest
    container_name: portainer
    pull_policy: always
    command: -H tcp://socket-proxy:2375
    networks:
      - socket_proxy
    security_opt:
      - no-new-privileges:true
    restart: always
    ports:
      - 9000:9000
    volumes:
      # - /var/run/docker.sock:/var/run/docker.sock #not required with socket_proxy
      - portainer_data:/data

networks:
  socket_proxy:
    external: true

volumes:
  portainer_data:
    name: portainer_data
    external: true

Yet this fails

When I log in, I see this:

instead of socket-proxy.

What am I missing?

(I replaced container name below to match yours)

There should be a new environment there, which uses "API" as the connection type and "tcp://socket-proxy:2375" for the Docker API URL.

I do have this in my compose file:

  environment:
     - DOCKER_HOST=tcp://socket-proxy:2375

But it has been a while since I set it up and I forgot if just including this environment variable does the trick (if it does not, what I actually forgot was if I added the new environment manually, switched to it and removed the default one you still see).

I manually entered the environment before seeing your post. But it's possible the enviromental variable would have done that. Thanks!

Even though I added socket-proxy to my environment, and also deleted the default environment, I still get log error.

I get that log message also. No impact in Portainer's functionality that I could notice.
