Error "Bad Gateway" Following is my docker setup

    restart: unless-stopped
    networks: 
      - traefik_gateway
    labels:

    command: pgweb --host postgres.abc.com --user abc --pass abc --db abc --ssl disable

Lemme know if you have further questions

Thx

You need to bind to 0.0.0.0, pgweb is listening on localhost only by default.

Didn't work for me, but I am considering something weird might be with my reverse proxy; I am gonna stash this for later on my todo list to figure I out.

I will post here once I do, anyways thx for suggestion @sosedoff

[sosedoff]

@jas99 btw was that a traefik config or docker compose or something else? i was replying from email after looking at your sample config, which didnt really ring a bell.

[JasCodes]

@sosedoff Yup those are docker compose files, the traefik configuration is actually done with command in compose file itself.

    command: traefik --docker 
--docker.domain=docker.localhost 
--logLevel=INFO 
--docker.watch 
--acme 
--acme.onhostrule 
--acme.httpchallenge.entrypoint=http 
--acme.storage=/etc/traefik/acme/acme.json 
--acme.email=dev@jas.bio 
--acme.entryPoint=https 
--entryPoints='Name:http Address::80 Redirect.EntryPoint:https' 
--entryPoints='Name:https Address::443 TLS' 
--defaultentrypoints=http,https

[sosedoff]

@jas99 i was able to start both services with a modified config:

version: "3.2"

services:
  traefik:
    container_name: traefik
    restart: unless-stopped
    image: traefik:1.6.4
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"
      - "/Users/sosedoff/docker/traefik:/etc/traefik/"
    #command: traefik --docker --docker.domain=docker.localhost --logLevel=INFO --docker.watch --acme --acme.onhostrule --acme.httpchallenge.entrypoint=http --acme.storage=/etc/traefik/acme/acme.json --acme.email=dev@jas.bio --acme.entryPoint=https --entryPoints='Name:http Address::80 Redirect.EntryPoint:https' --entryPoints='Name:https Address::443 TLS' --defaultentrypoints=http,https
    command: traefik --web --docker --docker.domain=docker.localhost --loglevel=INFO
    networks: 
      - gateway

  pgweb:
    container_name: pgweb
    image: sosedoff/pgweb
    restart: unless-stopped
    networks: 
      - gateway
    labels:
      - "traefik.enable=true"
      - "traefik.frontend.rule=Host:db.abc.com"
      - "traefik.acme.domains=db.abc.com"
      - "traefik.port=8081"
    command: pgweb --bind=0.0.0.0

networks:
  gateway:
    driver: bridge

Had to modify my /etc/hosts file with 127.0.0.1 db.abc.com.

I think main reason why you got 502 error is because pgweb did not start correctly due to invalid credentials / etc.

[sosedoff]

Im closing this issue since it has nothing to do with pgweb itself. To reiterate the issue: pgweb does work just fine with docker compose / kubernetes / swarm or any other container scheduler so if something does not work correctly make sure to double check the start arguments and network configuration. Also, feel free to ask any questions in this tread just in case.
