Problem with password to webGui

[tomuszom]

After each uprade (release new version) of pihole (docker-compose pull / docker-compose up -d) my password not working. env is set in file

pi@raspberrypi:~/IOTstack $ cat services/pihole/pihole.env TZ=Europe/Warsaw WEBPASSWORD=HbH9lFE4

only way to login is to set new password by "pihole -a -p"

Does your Pi-hole service definition in your docker-compose.yml look like this (from old-menu branch)?

  pihole:
    container_name: pihole
    image: pihole/pihole:latest
    ports:
      - "53:53/tcp"
      - "53:53/udp"
      - "67:67/udp"
      - "8089:80/tcp"
    env_file:
      - ./services/pihole/pihole.env
    volumes:
      - ./volumes/pihole/etc-pihole:/etc/pihole
      - ./volumes/pihole/etc-dnsmasq.d:/etc/dnsmasq.d
    dns:
      - 127.0.0.1
      - 1.1.1.1
    cap_add:
      - NET_ADMIN
    restart: unless-stopped

or this (from master branch):

  pihole:
    container_name: pihole
    image: pihole/pihole:latest
    ports:
      - "8089:80/tcp"
      - "53:53/tcp"
      - "53:53/udp"
      - "67:67/udp"
    environment:
      - TZ=${TZ:-Etc/UTC}
      - WEBPASSWORD=
      # see https://sensorsiot.github.io/IOTstack/Containers/Pi-hole/#adminPassword
      - INTERFACE=eth0
      - FTLCONF_MAXDBDAYS=365
      - PIHOLE_DNS_=8.8.8.8;8.8.4.4
      # see https://github.com/pi-hole/docker-pi-hole#environment-variables
    volumes:
      - ./volumes/pihole/etc-pihole:/etc/pihole
      - ./volumes/pihole/etc-dnsmasq.d:/etc/dnsmasq.d
    dns:
      - 127.0.0.1
      - 1.1.1.1
    cap_add:
      - NET_ADMIN
    restart: unless-stopped

It might not look like it's either but I'm really interested in these lines:

• from old-menu branch

      env_file:
        - ./services/pihole/pihole.env

• from master branch

      environment:
        - TZ=${TZ:-Etc/UTC}
        - WEBPASSWORD=

If your service definition contains the env_file: clause then what you are doing should be working.

However, if your service definition contains the environment: clause then docker-compose is not reading your services/pihole/pihole.env. I'm going to assume this is the most likely problem.

What I recommend you do is start by making your service definition look like the one from "master branch".

Next, do this:

$ cd ~/IOTstack
$ cat .env

If you get an error, or if you get output that doesn't contain:

Europe/Warsaw

then fix it with:

$ echo "TZ=Europe/Warsaw" >>.env

We have been working through the service definitions to try to make sure they all use - TZ=${TZ:-Etc/UTC}. That syntax means you only have to set the TZ once in the ~/IOTstack/.env file so this is as good a time as any to set it up properly.

If you have any other environment variables in your services/pihole/pihole.env that you haven't shown in your question then bring those over too.

Now, as for the password, the current service definitions have WEBPASSWORD= so it's a null string. That means PiHole won't have any password at all (that's how I run it myself).

If you want a password then add it:

- WEBPASSWORD=HbH9lFE4

Each time you "up" the container, the value of WEBPASSWORD is enforced. It's exactly like the old -a -p command.

Hope this helps. If you keep having problems then post your service definition here and I'll take another look.

Thanks, found issue. There was WEBPASSWORD in docker-compose.yml that was different that I always used. Changed and it's fine right now.
