Not a Bug: How to find version & update locast2tuner for Docker

[sumocomputers]

I am trying to understand the best way to know the version of locast2tuner running in Docker on Mac.

I have gone into the Docker Container command prompt, which dumps me to /bin/sh, but when running locast2tuner -h for example, it just sayslocast2tuner not found

Also, what is the best way to update to the latest version of locast2tuner for Docker? I just wasn't sure if stopping and starting the Container will do the trick, since I don't know how to check the version :-)

@sumocomputers

To get the version from inside of the container, you can run /locast2tuner -V

roddie@plex ~/docker% docker exec -it locast2tuner /bin/sh
/ # /locast2tuner -V
locast2tuner 0.1.40

Or do it all in one command:

roddie@plex ~/docker% docker exec -it locast2tuner /locast2tuner -V
locast2tuner 0.1.40

To update a Docker container is a little bit annoying, but basically you're going to do this:

Pull the latest version of the locast2tuner container image:

docker pull ghcr.io/wouterdebie/locast2tuner:latest

Stop the existing container:

docker stop locast2tuner

Remove the existing container:

docker rm locast2tuner

Then issue the docker run command that you started with originally.

The better way is to run this from docker-compose - (there's a sample in the repo and I have a blog post about it).

Then you just have to do two commands.

Update all container images:

docker-compose pull

Restart all containers with new versions:

docker-compose up -d

Thanks for this great info.

I will check out your post on docker-compose, since that seems to be a much better method.

@eiddor FYI - read the article on docker-compose and now successfully using it to run locast2tuner with all my config options too. Very cool, so thanks for the great help!

@sumocomputers I got bored and figured I'd help you get started with docker-compose. Based on your docker run command from #51

docker run -p 6078:6077 -v ~/Downloads/Locast2Tuner/.locast2tuner/:/app/config --name locast2tuner -d ghcr.io/wouterdebie/locast2tuner:latest

Here's what your docker-compose.yml file should look like:

version: '3'

services:
  locast2tuner:
    image: ghcr.io/wouterdebie/locast2tuner:latest
    container_name: locast2tuner
    volumes:
      - ~/Downloads/Locast2Tuner/.locast2tuner/:/app/config
    ports:
      - 6078:6077
    restart: unless-stopped

[eiddor]

Hahaha man we posted those at the same time - I'm glad you got it going!

Now you'll make the docker-compose pull and docker-compose up -d as part of your routine :-)

[sumocomputers]

The only thing I changed was:

restart: always

And I already used the 2 commands to update to 0.1.41 and it worked awesome!

[eiddor]

That's great!

So, the only reason I use unless-stopped instead of always is because I might want to test with a different version (in a different docker-compose.yml file), without conflicts between reboots or sometimes I don't want a container to run for a while (ie. one that connects to my NAS).

[wouterdebie]

Maybe we should have section in the README about updating?

[eiddor]

Yep! I will work on something when I get home later this week.

@eiddor sweet! Thanks!
