I have followed the docs and have the recommended folder structures for my Plex and arrs setup.

sonarr has a volume set as /data which gives it access to e.g. /data/usenet/downloads This is working fine with SABnzdb

I am using a seedbox for torrents. Looking at ruTorrent on the seedbox, I can see that the local download folder there is set to: /home/seedit4me/torrents/rtorrent

sonarr is reporting "No files found are eligible for import in:

• /home/seedit4me/torrents/rtorrent/Completed/tv-sonarr/filename.mkv

I have set a remote path in the download clients page in sonarr as follows:

• Host - ****.seedit4.me
• Remote path: /home/seedit4me
• local path: /data

I have ftp'd the mkv file to actual folder structure:

• /data/torrents/rtorrent/Completed/tv-sonaar/filename.mkv

The permissions on this file are:

• -rw-rw-r--

the folder permissions are:

• drwxrwxr-x 2 myacct myacct 4096 Aug 2 11:41 .
• drwxrwxr-x 3 myacct myacct

My uid=1000(my acct), same for gid I have set these as the PUID and PGID env variables in sonarr

The log file in sonarr is reporting: |Error|DownloadedEpisodesImportService|Import failed, path does not exist or is not accessible by Sonarr: /home/(removed)/torrents/rtorrent/Completed/tv-sonarr/filename.mkv

Seeing this, i tried mapping /home/(removed)/ to /data/ but that doesn't work either.

Can anyone guide me on what I am doing wrong? I feel like I've checked everything so I can't understand the issue at all.---

I have a Bluesky PDS running successfully. Now I'm trying to set up GoToSocial, an ActivityPub server that also uses sqlite. When I run

sudo docker compose up -d

I get the following error in the docker log for GoToSocial:

Error executing command: error creating dbservice: sqlite ping: Unable to open the database file (SQLITE_CANTOPEN)

Is this more likely to be a conflict between the two docker applications or something specific to GoToSocial? (I've gone through the sqlite issues I've been able to find in GoToSocial's GitHub.)

If something to do with running sqlite in two containers, do you have any tips to resolve the issue?

I've been thinking about writing a script that would alert me if there was an updated version of an image I was running.

DockerHub shows an image digest on the page for that tag:

And I can extract the digest for an image I am running with:

docker inspect --format='{{index .RepoDigests 0}}' jc21/nginx-proxy-manager:latest

This matches the one from the DockerHub screenshot. But I can't see a CLI way to get the image digest from a registry. It seems like:

docker manifest inspect jc21/nginx-proxy-manager:latest

should do it, but it pulls out the digest of each of the architecture builds for that tag instead of the one shown in dockerhub.

Is there a way to compare the current local image with one in a registry from the command line? Or perhaps there's a more sensible way to do this?

Suddenly, things aren't loading properly. For example Heimdall takes forever to load and Navidrome is timing out.

When I do docker-compose pull

It says says

Error response from daemon: Get "https://registry-1.docker.io/v2/" net/http: request cancelled while waiting for connection (Client.Timeout exceeded while awaiting headers)

Anyone know what's up or how to fix it?

I have found several docker containers that allow you to run a BOINC server as a container, but I haven’t seen any that give you access to the BOINC screensaver. My ideal would be if the screensaver itself was shown on a dedicated port so it could be used easily as a display without any controls popping up.

Sadly, I have no idea how to make this or how to get a custom container made. I guess I’m just throwing this idea out to the universe in hope that it happens someday.

I'm trying to create a postgres container, I have the following in my Docker Compose:

db:
  container_name: db
  image: postgres
  restart: always
  environment:
    #POSTGRES_USER="postgres"
    POSTGRES_PASSWORD: HDFnWzVZ5bGI
  ports:
    - 5432:5432
  volumes:
    - pgdata:/var/lib/postgresql/data
adminer:
  container_name: adminer
  image: adminer
  restart: always
  ports:
    - 8338:8080

And yet Docker keeps saying that the database is initialized and that the superuser is not specified. Where am I going wrong?

I've tried with and without equals, a hyphen, quotation marks. No matter what I try, it won't see it.

#Solution:

Find:

  volumes:
    - pgdata:/var/lib/postgresql/data

Replace:

  volumes:
    - /opt/postgres/data:/var/lib/postgresql/data

I am trying to come-up with a reusable template to quickly start new projects using my prefered tools and frameworks, and I'm happy with what I got. However, using Docker is quite new for me and I've probably done some weird or unconventional stuff in my docker-compose.yml or my Dockerfiles. I'd love to learn from people with more experience with Docker, so feel free to tell me everything that is wrong with my setup.

I'm more confident about the stuff I did with Python/Django and Nuxt, but all criticism is welcome. This also applies to the readme : I'd like to provide detailed instructions about working with this project template, so please report anything that is unclear or missing.

Thank you to anyone who takes the time to check it out and help me make this useful to as many people as possible.

Is it possible to create a volume that is a file, not a directory?

I am trying to make a simple structured nginx instance with docker. Using this command below to create the container...

docker container create -v ./nginx.conf:/etc/nginx/conf.d/nginx.conf -v .:/app/ -p 80:80 docker.io/nginx

And this is the file structure of it...

- www
-------------- public
---------------------------- index.html
- nginx.conf

And this is the nginx.conf

server {
    server_name localhost;
    listen 80;
    
    root /app/www/public;

    index index.html index.htm;
    autoindex on;
}

However the index.html will not work when I go to the localhost.

When I change the docker command to this it does work however, but this will also mirror all of the files and folder from my file structure into the containers /etc/nginx/conf.d/ directory

docker container create -v .:/etc/nginx/conf.d/ -v .:/app/ -p 80:80 docker.io/nginx

I am looking for something that can take a Dockerfile, like the following as an input:

FROM --platform=linux/amd64 debian:latest
ENV DEBIAN_FRONTEND=noninteractive

RUN apt update && apt install -y curl unzip libsecret-1-0 jq
COPY entrypoint.sh .
ENTRYPOINT [ "/entrypoint.sh" ]

And produce a a multi-stage Dockerfile where the last stage is built from scratch, with the dependencies for the script in the ENTRYPOINT (or CMD) copied over, like this:

FROM --platform=linux/amd64 debian:latest as builder
ENV DEBIAN_FRONTEND=noninteractive

RUN apt update && apt install -y curl unzip libsecret-1-0 jq

FROM --platform=linux/amd64 scratch as app
SHELL ["/bin/bash"]

# the binaries executed in entrypoint.sh
COPY --from=builder /bin/bash /bin/bash
COPY --from=builder /usr/bin/curl /usr/bin/curl
COPY --from=builder /usr/bin/jq /usr/bin/jq
COPY --from=builder /usr/bin/sleep /usr/bin/sleep

# shared libraries of the binaries
COPY --from=builder /lib/x86_64-linux-gnu/libjq.so.1 /lib/x86_64-linux-gnu/libjq.so.1
COPY --from=builder /lib/x86_64-linux-gnu/libcurl.so.4 /lib/x86_64-linux-gnu/libcurl.so.4
COPY --from=builder /lib/x86_64-linux-gnu/libz.so.1 /lib/x86_64-linux-gnu/libz.so.1
# ...a bunch of other shared libs...

# entrypoint
COPY entrypoint.sh /entrypoint.sh

ENTRYPOINT [ "/entrypoint.sh" ]

I've had pretty decent success creating images like this manually (using ldd to find the dependencies) based on this blog. To my knowledge, there's nothing out there that automates producing an image built from scratch, specifically. If something like this doesn't exist, I'm willing to build it myself.

I just installed Immich and while all my other containers have just required me to add to them to existing yaml, Immich requires its own yaml. That's fine I guess, but for the library, I wanna host it on my NAS and so I made the volume in my main Docker-Compose.yaml, the Immich yaml was all like, "what you talking about Willis?" because in my Immich environment I tried to point to something created in my main yaml. I thought I could work around this by adding an empty volume declaration, but now I can't find my uploads 😂 any idea on the correct methodology/workaround?

Whether you’re a Docker expert or new to the Docker community, you may be wondering about the best ways to optimize or get started quicker on Docker. Docker Captain Vladimir Mikhalev rounds up top Docker tips to help you supercharge developer productivity in 2024.

How did your journey begin? I feel like Docker has been getting mentioned for aeons and I've only just started using it now.

I know this seem like a typical "Your opinion man" post but honestly, is there anything really useful beyond hosting an adblocker? (read: complementary, not found elsewhere, that enhances own's personal needs and/or life as a whole). And yes, I'm aware of what can be hosted -- picture editors, video editors, webtops, dhcpcd, emulators, and so on.

But the question is -- why I'd need all that if these stuff can be found on any ordinary PC out there? Even phones. Hell, even on a smart tv. That is like "trying to reinvent the wheel" for no necessary purpose other than "to look cool". There's also "because its fun", but is it really fun doing pretty much the same thing over and over again? There isn't a "learning gap" between these hosting options -- all of em have (pretty much) the same procedure to get things running.

With that said... I've been trying really, REALLY hard to host more stuff but I can't go beyond hosting (only) an adblocker.
