Hi guys! I’m going at my first docker attempt…and I’m going in Proxmox. I created an LXC container, from which I installed docker, and portainer. Portainer seems happy to work, and shows its admin page on port 9443 correctly. I tried next running the image of immich, following the steps detailed in their own guide. This…doesn’t seem to open the admin website on port 2283. But then again, it seems to run in its own docker internal network (172.16.0.x). How should I reach immich admin page from another computer in the same network? I’m new to Docker, so I’m not sure how are images supposed to communicate within the normal computer network…Thanks!

    I have Immich working fine inside an LXC with docker, You just gotta make sure that Keyctl and Nesting are activated in the LXC container’s options in Proxmox and make sure to use the Immich recommended docker-compose file.

    If you still have problems try to take a look at the containers logs with the “docker logs” command to see if there’s an error message somewhere.

      Thanks! When I type my LXC’s IP:2283, I get unable to connect. I checked the docker-compose.yml and the port seems to be 2283:3001, but no luck at either. Is there anything that needs to be done on docker’s network in order to…“publish” a container to the local network so it can be seen? Or any docker running with a port can be reached via the host’s IP with no further config? Checking the portainer’s networks section, I can see an ‘immich-default’ network using bridge on 172.18.0.0/16, while the system’s bridge seems to be running at 172.17.0.0/16. Is this the correct defaults? Should I change anything?

      Thanks!

        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'

            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 :(

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

                  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.

    Did you say you’re running docker in LXC? So container in a container? If yes, that’s generally an anti pattern.

    I’ve been using proxmox mainly with lxc containers for years. I gave an lxc running docker and portainer, for a few services I have running in docker.

    I wouldn’t do it with anything critical it anything that needs mich performance or resources. But honestly most things don’t need that.

    So is you like me just need a few docker containers and you already have everything else running - this can be a fine way to do it. Go for it :)

    I routinely run my homelab services as a single Docker inside an LXC - they are quicker, and it makes backups and moving them around trivial. However, while you’re learning, a VM (with something conventional like Debian or Ubuntu) is probably advised - it’s a more common experience so you’ll get more helpful advice when you ask a question like this.

    Docker networking is fun :) (IMO).

    Without having a look at your container and how you configured it, if you have correctly mapped your ports and didn’t change anything fancy and don’t use a reverse proxy

    Your container should be accessible on your host’s IP mapped with you Immich docker port:

    HostIP:2283

    Edit: Also, don’t run a docker container in… Another container (LXC).

        Can you reach other services on that vm? If you don’t know that then test this first. ( May be run a python http service to test this?)
