Having Trouble Detecting an Agent

[drinksomewhiskey]

Hi all,

First of all thank you Amir for making such a great tool.

I am having a bit of trouble setting up an agent and having the host detect it. I was wondering if someone could review my docker compose files and let me know if I have something wrong.

The agent docker compose yaml is:

version: "3.8"

services:
  dozzle-agent:
    image: amir20/dozzle:latest
    container_name: dozzle_agent
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      - DOZZLE_MODE=agent
      - DOZZLE_HOSTNAME=LittleSurver
    ports:
      - 7007:7007
    restart: unless-stopped

The host docker compose yaml is:

version: "3.8"

services:
  dozzle:
    image: ghcr.io/amir20/dozzle:latest
    container_name: dozzle
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      - DOZZLE_HOSTNAME=BigSurver
      - DOZZLE_REMOTE_AGENT=192.168.1.58:7007
    ports:
      - 8080:8080
    restart: unless-stopped

Both machines are on the same subnet/VLAN on the network and are able to ping one another. This should not be a networking issue.

Both containers are able to build and run. However, the host is not able to connect to the agent. It shows up but is labeled offline.

I feel like I am missing a label or environment variable. I have read the Wiki, but may not fully understand as I am trying to build my own yamls from the docker run commands listed on the Wiki. As a side note, both machines are a Synolgy NAS.

Any ideas? Thank you in advance!

@drinksomewhiskey you should check your UI logs. The error would be there. You can also use the helper

$ docker run amir20/dozzle:latest agent-test [ip]:7007

You most likely have a firewall or something blocking it.

Ah. I didn't see that before. You need to pass a sub command. It's documented at https://dozzle.dev/guide/agent#how-to-create-an-agent

I tried this. The container does not build using command: agent. The log states error: invalid subcommand: agent. This is why I was trying to use DOZZLE_MODE=agent and DOZZLE_AGENT_MODE=true environment variables instead. This is the exact compose for with the agent command that I am running, which does not build:

version: "3.8"

services:
  dozzle-agent:
    image: amir20/dozzle:latest
    container_name: dozzle_agent
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
    command: agent
    environment:
      - DOZZLE_HOSTNAME=LittleSurver
    ports:
      - 7007:7007
    restart: unless-stopped

Sounds like you are pulling an older version.

This would be more helpful if you post the complete logs.

This was it. amir20/dozzle:latest was not working, but /ghcr.io/amir20/dozzle:latest worked.

I appreciate your quick replies and thank you again for building something so cool.
