I installed ollama for using AI localy on my computer. And now i want to use OpenWebUI. That needs to be installed in docker, so i did that and it should host a page which is gui for openwebui. And its working but i have this problem: https://github.com/open-webui/open-webui/discussions/4376

So i pasted this command as they say:

docker run -d --network=host -v open-webui:/app/backend/data -e OLLAMA_BASE_URL=http://127.0.0.1:11434 --name open-webui --restart always ghcr.io/open-webui/open-webui:main

But after that it returned this error code: docker: Error response from daemon: Conflict. The container name "/open-webui" is already in use by container "1cbc8ac3b80f2a6921778964f94eff32541a4540ee6ab5d3335427a0fc8366a8". You have to remove (or rename) that container to be able to reuse that name. See 'docker run --help'.

Can anyone help me with this?

I'm experimenting with i2p and a librewolf container setup in Docker compose. However, the i2p web console front end (127.0.0.1:7657) becomes inaccessible if the container itself is restarted. This can be remedied by removing the directories that get created by the volume mappings in the compose file, but this obviously not ideal. Anyone have experience with this problem? I've seen hints from people online suggesting that the data in those directories getting somehow corrupted. I have not yet investigated that further.

I have a docker compose file with a bind volume. It basically mounts /media/user/drive/media to the container's /mnt.

It works as expected when /media/user/drive/ is mounted and its media folder has the files I want the container to see.

However, as it's a network drive, the container usually tries to start before it is mounted, so it would throw the error that /media/user/drive/media doesn't exist. So I created an empty folder in /media/user/drive called media while the drive was not mounted so that at least the container starts with the volume /mnt being empty until the network drive gets mounted and all the files appear at /media/user/drive/media.

To my surprise, when the drive gets mounted, even though if I do ls /media/user/drive/media it lists the drive contents correctly, the container still sees /mnt empty.

How would I go about getting the drive files inside the docker container when it automatically starts?

I am hoping that you awesome people can help me with something I've noticed in my Plex logs. Quick notes on my set up:

Mini PC running Ubuntu 22.04, portainer, Plex, arrs and calibre all running in docker. All of these except Plex are using a bridge network that I created in portainer. The PC is connected to the router by ethernet cable, and I have set up a static IP in the router settings. I have also added the static IP info into the network settings in Ubuntu.

The following text is repeated over and over in the Plex Media Server log, about 6 seconds apart. My playback is mostly fine, but I have been experiencing buffering. Regardless this can't be right!.

n.b. I did post elsewhere but I feel that this is not necessarily Plex related and you can likely help with this more technical question.

I have readarr and all other arrs working in Ubuntu with docker portainer. I followed the trash guides and LinuxServerio guides to get me this far. I want to expand my book library, and so I have added calibre.

After having calibre import my book library, I went to readarr to delete the root, and re-add it with the new path to the calibre library. I am having problems with the Calibre Settings on the Add Root page.

The calibre server is listening at 172.18.0.2, port 8081, HTTP. I have created a user account on the calibre "sharing over the net" page. In readarr, I have set the Calibre Host to 172.18.0.2 and the Calibre Port to 8081. When I click save, I get the error Unknown exception: Http request timed out.

Most of the guides I have found are 3 or 4 years old. On one guide the Calibre Host was set to: calibre. That doesn't work. Setting the Host to the IP of my server doesn't work either.

Can any one help? I don't know if I have a permissions or firewall problem, or if I am just doing something wrong. The calibre logs are not showing any issues. I have copied the .yaml files used below.

-services:

  • calibre:
  • image: lscr.io/linuxserver/calibre:latest
  • container_name: calibre
  • security_opt:

Hi everyone !

Intro

Was a long ride since 3 years ago I started my first docker container. Learned a lot from how to build my custom image with a Dockerfile, loading my own configurations files into the container, getting along with docker-compose, traefik and YAML syntax... and and and !

However while tinkering with vaultwarden's config and changing to postgresSQL there's something that's really bugging me...

Questions


  • How do you/devs choose which database to use for your/their application? Are there any specific things to take into account before choosing one over another?

  • Does consistency in database containers makes sense? I mean, changing all my containers to ONLY postgres (or mariaDB whatever)?

  • Does it make sense to update the database image regularly? Or is the application bound to a specific version and will break after any update?

  • Can I switch between one over another even if you/devs choose to use e.g. MariaDB ? Or is it baked/hardcoded into the application image and switching to another database requires extra programming skills?

Maybe not directly related to databases but that one is also bugging me for some time now:

  • What's redis role into all of this? I can't the hell of me understand what is does and how it's linked between the application and database. I know it's supposed to give faster access to resources, but If I remember correctly, while playing around with Nextcloud, the redis container logs were dead silent, It seemed very "useless" or not active from my perspective. I'm always wondering "Humm redis... what are you doing here?".

Thanks :)

Edit - marking as solved.

  • Remote path: /home/seedit4me
  • local path: /data

This is now working, I don't know why it wasn't before. ‐------------

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 am working on this django docker project template with this certbot setup, Dockerfile

FROM certbot/certbot:v1.27.0

COPY certify-init.sh /opt/
RUN chmod +x /opt/certify-init.sh

ENTRYPOINT ["/opt/certify-init.sh"]

entrypoint

#!/bin/sh

set -e

echo "Getting certificate..."

certbot certonly \
    --webroot \
    --webroot-path "/vol/www/" \
    -d "$DOMAIN" \
    --email $EMAIL \
    --rsa-key-size 4096 \
    --agree-tos \
    --noninteractive

if [ $? -ne 0 ]; then
    echo "Certbot encountered an error. Exiting."
    exit 1
fi

#for copying the certificate and configuration to the volume
if [ -f "/etc/letsencrypt/live/${DOMAIN}/fullchain.pem" ]; then
    echo "SSL cert exists, enabling HTTPS..."
    envsubst '${DOMAIN}' < /etc/nginx/nginx.prod.conf > /etc/nginx/conf.d/default.conf
    echo "Reloading Nginx configuration..."
    nginx -s reload
else
    echo "Certbot unable to get SSL cert,server HTTP only..."
fi


echo "Setting up auto-renewal..."
apk add --no-cache dcron
echo "0 12 * * * /usr/bin/certbot renew --quiet" | crontab -
crond -b

problem with this setup is,certbot exits after initial run of getting the certificate and when it's renew time it require manual intervention.

Now There are two choices

  1. set restart: unless-stopped in docker compose file so it keeps restarting the container and with cron job to renew the certificate when required.

  2. Set cron job in host machine to restart the container.

Are there any other/more option to tackle this situation.

I am running Fedora Server with Docker installed, and it has a folder that connects to my NAS via SMB. I will have all of my Docker files (and Compose configs) stored on my NAS, since it has a lot more storage. I am worried that Docker will glitch out and cause a mess, since my NAS starts ~2 minutes later than my server from a reboot. Is there something that I can do to make sure Docker is able to connect to the SMB share safely?

I have a NAS where I tested to see if some apps could run on it without a server. They overloaded the CPU, so I am now wanting to move them over to a more powerful workstation. I'm used to Compose files/configs, but it seems that my NAS uses plain Docker. Is there a way to extract the configs/long terminal setup commands? I have Portainer installed, if that makes it easier.

I built my first image locally and now I'm dancing around my desk to myself in satisfaction. I was anxious AF and so that meant I had a million extra questions along the way and everyone helped me. I'm truly grateful. Thanks for teaching me/holding my hand. I can't put into words my gratitude, but truly, thank you so so much.

There's a service that I want to use, however for reasons, it no longer has any builds available. Consequently, I am thinking of building it myself. How does one go about doing that and then afterwards, how do I get it up on Docker hub? Can I just create an account and upload?

If I have

version: "3.8"

services: 
  example1:
    image: example.com/example1:latest
  ports: 8000:80
volumes: 
  - shared_example:/data
services: 
  example2:
    image: example.com/example2:latest
  ports: 8080:80
volumes: 
  - shared_example:/data

volumes:
  shared_example: 
    driver_opts: 
      type: nfs
      o: "192.100.1.100, nolock,soft,rw"
      device: ":/local/shared"

Will that slow things down or is the proper solution to have

volumes:
  shared_example1: 
    driver_opts: 
      type: nfs
      o: "192.100.1.100, nolock,soft,rw"
      device: ":/local/shared"
  shared_example2:

      type: nfs
      o: "192.100.1.100, nolock,soft,rw"
      device: ":/local/shared"

Or even

volumes:
  shared_example1: 
  shared_example2: 
    driver_opts: 
      type: nfs
      o: "192.100.1.100, nolock,soft,rw"

I have my main compose file which has a bunch of services in and while it makes it easier to manage, it's also limiting when I wanna use postgres:// to access a database rather than exposing a port. I'm wondering if I can remedy this by moving it to a new network and(?) stack?

If so, is it just as simple as adding

networks
  - new network name
stacks
  - new stacks name

I'm still curious as to the answer, but it's not something I need.

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?
