-Docker installation
-===================
-
-This section provides instructions for installing a chatmail relay
-using Docker Compose.
-
-.. note::
-
-    - Docker support is experimental, CI builds and tests the image automatically, but please report bugs.
-    - The image wraps the cmdeploy process detailed in the :doc:`getting_started` instructions in a Debian-systemd image with r/w access to `/sys/fs`
-    - Currently amd64-only (arm64 should work but is untested).
-
-
-Setup Preparation
-----------------
-
-We use ``chat.example.org`` as the chatmail domain in the following
-steps. Please substitute it with your own domain.
-
-1. Install docker and docker compose v2 (check with `docker compose version`), install, e.g., on
-    - Debian 12 through the `official install instructions <https://docs.docker.com/engine/install/debian/#install-using-the-repository>`_
-    - Debian 13+ with `apt install docker docker-compose`
-
-2. Setup the initial DNS records.
-   The following is an example in the familiar BIND zone file format with
-   a TTL of 1 hour (3600 seconds).
-   Please substitute your domain and IP addresses.
-
-   ::
-
-       chat.example.org. 3600 IN A 198.51.100.5
-       chat.example.org. 3600 IN AAAA 2001:db8::5
-       www.chat.example.org. 3600 IN CNAME chat.example.org.
-       mta-sts.chat.example.org. 3600 IN CNAME chat.example.org.
-
-3. Configure kernel parameters on the host, as these can not be set from the container::
-
-       echo "fs.inotify.max_user_instances=65536" | sudo tee -a /etc/sysctl.d/99-inotify.conf
-       echo "fs.inotify.max_user_watches=65536" | sudo tee -a /etc/sysctl.d/99-inotify.conf
-       sudo sysctl --system
-
-
-Docker Compose Setup
--------------------
-
-Pre-built images are available from GitHub Container Registry. The
-``main`` branch and tagged releases are pushed automatically by CI::
-
-    docker pull ghcr.io/chatmail/relay:main      # latest main branch
-    docker pull ghcr.io/chatmail/relay:1.2.3     # tagged release
-
-
-Create service directory
-^^^^^^^^^^^^^^^^^^^^^^^^
-
-Either:
-
- Create a service directory and download the compose files::
-
-    mkdir -p /srv/chatmail-relay && cd /srv/chatmail-relay
-    wget https://raw.githubusercontent.com/chatmail/relay/refs/heads/main/docker/docker-compose.yaml
-    wget https://raw.githubusercontent.com/chatmail/relay/refs/heads/main/docker/docker-compose.override.yaml.example -O docker-compose.override.yaml
-
- or clone the chatmail repo and enter the docker directory::
-
-   git clone https://github.com/chatmail/relay
-   cd relay/docker
-
-
-Customize and start
-^^^^^^^^^^^^^^^^^^^
-
-1. Set the fully qualified domain name of the relay::
-
-       echo 'MAIL_DOMAIN=chat.example.org' > .env
-
-   The container generates a ``chatmail.ini`` with defaults from
-   ``MAIL_DOMAIN`` on first start. To customize chatmail settings, mount
-   your own ``chatmail.ini`` instead (see `Custom chatmail.ini`_ below).
-
-2. All local customizations (data paths, extra volumes, config mounts) go in
-   ``docker-compose.override.yaml``, which Compose merges automatically with
-   the base file. By default, all data is stored in docker volumes, you will
-   likely want to at least create and configure the mail storage location, but
-   you might also want to configure external TLS certificates there.
-
-3. Start the container::
-
-       docker compose up -d
-       docker compose logs -f chatmail   # view logs, Ctrl+C to exit
-
-4. After installation is complete, open ``https://chat.example.org`` in
-   your browser.
-
-Finish install and test
-----------------------
-
-You can test the installation with::
-
-        pip install cmping chat.example.org # or
-        uvx cmping chat.example.org # if you use https://docs.astral.sh/uv/
-
-You should check and extend your DNS records for better interoperability::
-
-    # Show required DNS records
-    docker exec chatmail cmdeploy dns --ssh-host @local
-
-You can check server status with::
-
-    docker exec chatmail cmdeploy status --ssh-host @local
-
-You can run some benchmarks (can also run from any machine with cmdeploy installed)::
-
-    docker exec chatmail cmdeploy bench
-
-You can run the test suite with::
-
-    docker exec chatmail cmdeploy test --ssh-host localhost
-
-You can look at logs::
-
-    docker exec chatmail journalctl -fu postfix@-
-
-
-Customization
-------------
-
-Website
-^^^^^^^^^^^^^^
-
-You can customize the chatmail landing page by mounting a directory with
-your own website source files.
-
-1. Create a directory with your custom website source::
-
-       mkdir -p ./custom/www/src
-       nano ./custom/www/src/index.md
-
-2. Add the volume mount in ``docker-compose.override.yaml``::
-
-       services:
-         chatmail:
-           volumes:
-             - ./custom/www:/opt/chatmail-www
-
-3. Restart the service::
-
-       docker compose down
-       docker compose up -d
-
-
-Custom chatmail.ini
-^^^^^^^^^^^^^^^^^^^
-
-If you want to go beyond simply setting the ``MAIL_DOMAIN`` in ``.env``, you
-can use a regular `chatmail.ini` to give you full control.
-
-1. Extract the generated config from a running container::
-
-       docker cp chatmail:/etc/chatmail/chatmail.ini ./chatmail.ini
-
-2. Edit ``chatmail.ini`` as needed.
-
-3. Add the volume mount in ``docker-compose.override.yaml`` ::
-
-       services:
-         chatmail:
-           volumes:
-             - ./chatmail.ini:/etc/chatmail/chatmail.ini
-
-4. Restart the container, the container skips generating a new one: ::
-
-       docker compose down && docker compose up -d
-
-
-External TLS certificates
-^^^^^^^^^^^^^^^^^^^^^^^^^
-
-If TLS certificates are managed outside the container (e.g. by certbot,
-acmetool, or Traefik on the host), mount them into the container and set
-``TLS_EXTERNAL_CERT_AND_KEY`` in ``docker-compose.override.yaml``.
-Changed certificates are picked up automatically via inotify.
-See the examples in the example override and :ref:`external-tls` in the getting started guide for details.
-
-
-Migrating from a bare-metal install
------------------------------------
-
-If you have an existing bare-metal chatmail installation and want to
-switch to Docker:
-
-1. Stop all existing services::
-
-       systemctl stop postfix dovecot doveauth nginx opendkim unbound \
-         acmetool-redirector filtermail filtermail-incoming chatmail-turn \
-         iroh-relay chatmail-metadata lastlogin mtail
-       systemctl disable postfix dovecot doveauth nginx opendkim unbound \
-         acmetool-redirector filtermail filtermail-incoming chatmail-turn \
-         iroh-relay chatmail-metadata lastlogin mtail
-
-2. Copy your existing ``chatmail.ini`` and mount it into the container
-   (see `Custom chatmail.ini`_ above)::
-
-       cp /usr/local/lib/chatmaild/chatmail.ini ./chatmail.ini
-
-3. Copy persistent data into the ``./data/`` subdirectories (for example, as configured in `Customize and start`_) ::
-
-       mkdir -p data/dkim data/certs data/mail
-
-       # DKIM keys
-       cp -a /etc/dkimkeys/* data/dkim/
-
-       # TLS certificates
-       rsync -a /var/lib/acme/ data/certs/
-
-   Note that ownership of dkim and acme is adjusted on container start.
-
-   For the mail directory::
-
-       rsync -a /home/vmail/ data/mail/
-
-   Alternatively, mount ``/home/vmail`` directly by changing the volume
-   in ``docker-compose-override.yaml``::
-
-       - /home/vmail:/home/vmail
-
-   The three ``./data/`` subdirectories cover all persistent state.
-   Everything else is regenerated by the ``configure`` and ``activate``
-   stages on container start.
-
-Building the image
------------------
-
-Clone the repository and build the Docker image::
-
-    git clone https://github.com/chatmail/relay
-    cd relay
-    docker/build.sh
-
-The build bakes all binaries, Python packages, and the install stage
-into the image. After building, only the ``docker/`` directory and a ``.env``
-with ``MAIL_DOMAIN`` are needed to run the container. The `build.sh` passes the
-git hash onto the docker build so it can be determined if there has been a
-change that warrants a redeploy.
-
-You can transfer a locally built image to your server directly (pigz is parallel `gzip` which can be used instead as well) ::
-
-    docker save chatmail-relay:latest | pigz | ssh chat.example.org 'pigz -d | docker load'
-
-
-Forcing a full reinstall
------------------------
-
-On container start, only the ``configure`` and ``activate`` stages run by default.
-
-To force a full reinstall (e.g. after updating the source), either
-rebuild the image::
-
-    docker compose build chatmail
-    docker compose up -d
-
-Or override the stages at runtime without rebuilding::
-
-    CMDEPLOY_STAGES="install,configure,activate" docker compose up -d

Uses the same 3-step pattern as pyinfra's apt.deb: tolerant first dpkg -i, apt-get --fix-broken, then final dpkg -i to fail if there are still errors.	2026-03-21 16:17:37 +01:00
