Dex configuration missing `serve`

Hi, I'm trying to follow the auth with dex path. After launching dex there are 0 replicas and sudo docker service logs dex_dex gives the following in the log

 | error: cannot lookup path for command serve: exec: "serve": executable file not found in $PATH

 | error: cannot lookup path for command serve: exec: "serve": executable file not found in $PATH

Ok, I htink I've managed to fix it 🤔

version: '3'

services:
  dex:
    image: dexidp/dex
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - /var/data/config/dex/config.yml:/config.yml:ro
    networks:
      - traefik_public
    # FIX
    command: ['dex', 'serve', '/config.yml']
    deploy:
      labels:
      - "traefik.enable=true"
      - "traefik.docker.network=traefik_public"
      - "traefik.http.routers.dex.rule=Host(`dex.frdr.cc`)"
      - "traefik.http.routers.dex.enrypoints=https"
      - "traefik.http.services.dex.loadbalancer.server.port=5556"

networks:
  traefik_public:
    external: true

version: '3'

services:
  dex:
    image: dexidp/dex
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - /var/data/config/dex/config.yml:/config.yml:ro
    networks:
      - traefik_public
    # FIX
    command: ['dex', 'serve', '/config.yml']
    deploy:
      labels:
      - "traefik.enable=true"
      - "traefik.docker.network=traefik_public"
      - "traefik.http.routers.dex.rule=Host(`dex.frdr.cc`)"
      - "traefik.http.routers.dex.enrypoints=https"
      - "traefik.http.services.dex.loadbalancer.server.port=5556"

networks:
  traefik_public:
    external: true

While this fixes the first problem there seems to be issues with sqlite permissions/setup as well

do we need the dex in front of the command? i.e., this (used to) work:

    command: ['serve','/config.yml']

    command: ['serve','/config.yml']

huh. you're right, they must have changed the image, this no longer works:

❯ docker run --rm -it dexidp/dex serve                                                  07:44:49

thanks for the PR 🙂 what's the permissions issue?

tomcheOP•11mo ago

Had 2 issues which were complaining about permissions/missing files. Essentially fixed with these

sudo touch /var/data/config/traefik-forward-auth/config.ini
sudo chmod 644 /var/data/config/traefik-forward-auth/config.ini
sudo mkdir /var/data/dex
sudo touch /var/data/dex/dex.db
sudo chmod 644 /var/data/dex/dex.db

sudo touch /var/data/config/traefik-forward-auth/config.ini
sudo chmod 644 /var/data/config/traefik-forward-auth/config.ini
sudo mkdir /var/data/dex
sudo touch /var/data/dex/dex.db
sudo chmod 644 /var/data/dex/dex.db

So sqlite db for dex and config.ini for forward auth. Dunno if it;s the best solution 😉 But it works on my machine ™️
