Basic docker networking?

@PunkiBas@lemmy.world · 8 months ago

That all seems correct, the way to expose services with a docker-compose is by using the:

ports:
  - 2283:3001

That means that you expose whatever is at port 3001 in the cointainer (in this case the Immich server inside the docker container, which is exposed by default to 3001) to port 2283 of the host machine (in this case, your LXC container). So it should work if everything else is set up correctly.

The 172.x.x.x networks are normal internal networks for docker to use, normally you needn’t care about them because you just expose whichever port you need via the ports command above.

Are you following this step by step to set it all up? is your .env file properly set up? did you check the containers logs?

Thanks…I did follow their guide, step by step. The only thing that I customized was the immich uploads folder, which I want it to go to my NAS. I have it set up on an NFS mount handled by proxmox, and then it’s just a transparent bind mount in the LXC. The user in the lxc container has read/write access to this location, and docker runs on this same user. But I reckon I’m addressing this in docker in a horribly messed way, as I’ve never used it before. Checking the docker logs immich_server, I’m getting this:

[Nest] 7  - 04/08/2024, 9:53:08 AM     LOG [SystemConfigService] LogLevel=log (set via system config)
node:fs:1380
  const result = binding.mkdir(
                         ^

Error: EACCES: permission denied, mkdir 'upload/library'

  errno: -13,
  code: 'EACCES',
  syscall: 'mkdir',
  path: 'upload/library'

Let’s see… So let’s say my LXC container has a /mnt/NAS-immich-folder path, already mounted and with rw permissions. Then I edited my docker-compose.yml volumes line as follows:

    volumes:
      - /mnt/NAS-immich-folder:/mnt/immich
      - ${UPLOAD_LOCATION}:/mnt/immich
      - /etc/localtime:/etc/localtime:ro

And my .env path looks like:

# The location where your uploaded files are stored
UPLOAD_LOCATION=/media/immich

…I’m sure I’m doing something horribly wrong besides the no-no of docker over LXC…Is there anything messed in these paths? What am I doing wrong? Thanks so much!

Ah! now I see the problem

permission denied, mkdir ‘upload/library’

It’s clearly having permission problems with the image library directory.

Also:

volumes:
 - /mnt/NAS-immich-folder:/mnt/immich
 - ${UPLOAD_LOCATION}:/mnt/immich

with this command you are trying to mount this directory from your LXC machine:

/mnt/NAS-immich-folder

into this directory inside the immich container:

/mnt/immich

And then you also try to mount a second directory there in the next line. But immich doesn’t use /mnt/immich for its library, it uses this:

/usr/src/app/upload

You should NOT edit the default docker-compose.yml file. Instead you should only edit the .env file like so:

UPLOAD_LOCATION=/mnt/NAS-immich-folder

I can also see that there’s a specific tutorial on how to set it up with portainer. In that case you might have to edit the docker compose file to replace .env with stack.env and place the contents of the env file in the advanced-> environment variables of portainer.

Try these things and ask here again if you can’t get it running.

Wow thanks! Let me take a look, I missed the portainer part! Sigh…I followed through the instructions. I deleted the previous stack, and created a new one, this time all the way from portainer. This time I ONLY modified the .env file, well and according to the instructions the .yaml referring to the .env as stack.env now. Made it deploy…and nothing. Still getting the same mkdir error :(

@PunkiBas@lemmy.world · 8 months ago

Might be some NFS permissions problem, can you try some other temp directory with say 777 permissions to see if it’s that?

@iturnedintoanewt@lemm.ee · 8 months ago

Thanks! Seems more about how to properly map a local host path/mount on docker. For which I’m completely noob…I think this is where I’m failing right now.
