Attempting to install in docker container but keep running into "bash: /usr/local/bin/docker-compose: cannot execute binary file: Exec format error"

[Inkertus]

I appear to be doing everything according to the videos I have seen thus far, but keep running into that pesky exec format error on my Pi 4B. There does appear to be a version coded for ARM but I'm lost at this point.
Any help?

[alexjustesen]

Are you using 32bit or 64bit version of PI OS (or something else) on your 4B?

[Inkertus]

I must not know enough what I'm doing because I'm trying to follow the Docker Compose bit and it keeps throwing errors. Times like this make me wish for basic, easy-to-use "double-click to run" stuff.

[Inkertus]

and yes I do have docker compose installed

[alexjustesen]

Can you share the composer script you're using or are you copying it from the docs as is?

[Inkertus]

This, or a script 99% like it, is the one I've been trying to use. I have been known to be blind occasionally but I don't believe this to be the case here.

[alexdelprete]

the exec format error you were having is due to the fact you are running docker-compose instead of docker compose.

you have probably an old installation of docker/docker-compose on the system.

run docker version and docker compose version to check what versions you have installed.

[alexdelprete]

are you really using /path/to/directory in the compose file?

That has to be a real directory...it was just an example in the docs to tell the user to configure the appropriate path.

[Inkertus]

I barely know what I am doing here, I fully admit that. I know enough to follow a guide and do basic troubleshooting for command line and scripting projects and usually wander my way thru. I have edited the file to

and also tried
volumes:
- '/home/pi-serv-user/docker/speedtest-tracker/docker-compose.yml:/config'

with the same error.

[Inkertus]

...in accordance with the tutorial I tried following.

[alexdelprete]

@Inkertus if you use docker, you have to know the MINIMUM stuff, the basics, otherwise you will always have issues.

/home/pi-serv-user/docker/speedtest-tracker/docker-compose.yml:/config

you are mapping a file to a folder, I don't know what guide you are following, but you are not reading the docs.

I'll help you, but please read something about docker and docker-compose in the future.

I assume the folder ~/docker/speedtest-tracker in which you have the docker-compose file is a specific folder for speedtest-tracker you created. If so, create two subfolders in there config and certs:

This is the folder that contains docker-compose.yml file:

• ~/docker/speedtest-tracker/docker-compose.yml

These are the subfolders that need to be present:

• ~/docker/speedtest-tracker/config
• ~/docker/speedtest-tracker/certs

Then modify ~/docker/speedtest-tracker/docker-compose.yml like this:

version: '3.3'
services:
  speedtest-tracker:
    image: ghcr.io/alexjustesen/speedtest-tracker:latest
    container_name: speedtest-tracker
    restart: unless-stopped
    ports:
      - 8080:80
      - 8443:443
    environment:
      - PUID=1000
      - PGID=1000
      - SSL_MODE=mixed
    volumes:
      - $PWD/config:/config
      - $PWD/certs:/etc/ssl/web

$PWD will be expanded to the folder where the docker-compose is (~/docker/speedtest-tracker)

After you updated the docker-compose file, run this to recreate the container:

docker compose up -d --force-recreate --remove-orphans

[Inkertus]

Thank you for your help so far. I have modified as instructed, with and without the last line in the document. The IDs are 1000 for both.

[Inkertus]

I got rid of the SSL_MODE=mixed and ran again. Now it seems to be running

[alexdelprete]

One more thing:

PUID and PGID have to be mapped to the user owning the config and certs subfolders. You are using 1000, but you need to verify what is the ID of the user you are running (pi-serv-user).

So run this command: id pi-serv-user

You will have something like this (my user is alexdelprete):

❯ id alexdelprete
uid=1000(alexdelprete) gid=1000(alexdelprete)

The numbers you will see (in my case it's 1000 and 1000) are the ones you need to use in the docker-compose file as PUID and PGID, ok?

[alexdelprete]

Please don't post screenshots, copy&paste the output of the shell in the future, using <> symbol in the editing bar to format the text as code.

There was an error, my bad, I updated the environment section in the docker-compose file, like this:

    environment:
      - PUID=1000
      - PGID=1000
      - SSL_MODE=mixed

Update docker-compose.yml and run: docker compose up -d --force-recreate --remove-orphans

[Inkertus]

Again, thank you very much. I'm headed out for now but I did get it running and a non-default user configured. I do need to get the documentation up and read so I can at least get an idea of what I'm doing and be less of (I figure) a bother.
Thanks again for both the help and the project.

[alexdelprete]

No problem @Inkertus, no bother. Just my recommendation to all users to have a minimum understanding of what they're using so they can troubleshoot and maintain the services they're using. It's not setup & install like on windows. :)

Enjoy ST.
