latest | ✅ | Stable releases. |
develop | ✅ | Pre-releases only. |
Application Setup
To generate keys for SECRET_KEY_BASE
& OTP_SECRET
run docker run --rm -it -w /app/www --entrypoint rake dev.cat-enby.club/nikurasu/mastodon secret
once for each.
To generate keys for VAPID_PRIVATE_KEY
& VAPID_PUBLIC_KEY
run docker run --rm -it -w /app/www --entrypoint rake dev.cat-enby.club/nikurasu/mastodon mastodon:webpush:generate_vapid_key
To use tootctl
you can run something like docker exec -it -w /app/www mastodon bin/tootctl <command>
This container requires separate postgres and redis instances to run.
We support all of the official environment variables for configuration. In place of adding them all to your run/compose you can use an env file such as this example from the upstream project.
For more information check out the mastodon documentation.
Strict reverse proxies
This image automatically redirects to https with a self-signed certificate. If you are using a reverse proxy which validates certificates, you need to disable this check for the container.
Usage
Here are some example snippets to help you get started creating a container.

Parameters
Container images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal>
respectively. For example, -p 8080:80
would expose port 80
from inside the container to be accessible from the host's IP on port 8080
outside the container.

Environment variables from files (Docker secrets)
You can set any environment variable from a file by using a special prepend FILE__
.
As an example:
-e FILE__PASSWORD=/run/secrets/mysecretpassword
Will set the environment variable PASSWORD
based on the contents of the /run/secrets/mysecretpassword
file.
Umask for running applications
For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022
setting.
Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.
User / Group Identifiers
When using volumes (-v
flags) permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID
and group PGID
.
Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.
In this instance PUID=1000
and PGID=1000
, to find yours use id user
as below:
$ id username
uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)
Support Info
- Shell access whilst the container is running:
docker exec -it hometown /bin/bash
- To monitor the logs of the container in realtime:
docker logs -f hometown
- container version number
docker inspect -f '{{ index .Config.Labels "build_version" }}' hometown
- image version number
docker inspect -f '{{ index .Config.Labels "build_version" }}' dev.cat-enby.club/nikurasu/hometown:latest
Updating Info
Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (ie. nextcloud, plex), we do not recommend or support updating apps inside the container. Please consult the Application Setup section above to see if it is recommended for the image.
Below are the instructions for updating containers:
Via Docker Compose
- Update all images:
docker-compose pull
- or update a single image:
docker-compose pull hometown
- or update a single image:
- Let compose update all containers as necessary:
docker-compose up -d
- or update a single container:
docker-compose up -d hometown
- or update a single container:
- You can also remove the old dangling images:
docker image prune
Via Docker Run
- Update the image:
docker pull dev.cat-enby.club/nikurasu/hometown:latest
- Stop the running container:
docker stop hometown
- Delete the container:
docker rm hometown
- Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your
/config
folder and settings will be preserved) - You can also remove the old dangling images:
docker image prune
Via Watchtower auto-updater (only use if you don't remember the original parameters)
-
Pull the latest image at its tag and replace it with the same env variables in one run:
docker run --rm \ -v /var/run/docker.sock:/var/run/docker.sock \ containrrr/watchtower \ --run-once hometown
-
You can also remove the old dangling images:
docker image prune
Note: We do not endorse the use of Watchtower as a solution to automated updates of existing Docker containers. In fact we generally discourage automated updates. However, this is a useful tool for one-time manual updates of containers where you have forgotten the original parameters. In the long term, we highly recommend using Docker Compose.
Image Update Notifications - Diun (Docker Image Update Notifier)
- We recommend Diun for update notifications. Other tools that automatically update containers unattended are not recommended or supported.
Building locally
If you want to make local modifications to these images for development purposes or just to customize the logic:
git clone https://dev.cat-enby.club/nikurasu/docker-hometown.git
cd docker-hometown
docker build \
--no-cache \
--pull \
-t dev.cat-enby.club/nikurasu/hometown:latest .
The ARM variants can be built on x86_64 hardware using multiarch/qemu-user-static
docker run --rm --privileged multiarch/qemu-user-static:register --reset
Once registered you can define the dockerfile to use with -f Dockerfile.aarch64
.
