This is a project to get the Mailpiler running in a docker compose system in a simple and uncomplicated way.
You can find more information about the Piler project here.
https://www.mailpiler.org/ or https://github.com/jsuto/piler
The Piler image is built locally from build/Dockerfile when the containers are started
(docker compose up). The Dockerfile downloads the official Piler package from
https://github.com/jsuto/piler/releases and verifies its SHA256 checksum.
The image can also be built manually with bash build/build.sh.
Current versions:
| Component | Version |
|---|---|
| Piler | 1.4.9 |
| Base image | Ubuntu 26.04 (resolute), PHP 8.5 |
| MariaDB | 12.3.3 (LTS) |
| Manticore Search | 29.9.0 |
| Memcached | 1.6 |
| nginx-proxy / acme-companion (Let's Encrypt) | 1.11 / 2.8 |
- Install Docker and dependencies
apt install curl git -y
curl -sSL https://get.docker.com/ | CHANNEL=stable sh
systemctl enable --now docker
- Docker Compose
The Docker installation above already includes the Docker Compose plugin (docker compose).
Docker Compose v2 or higher is required.
- reboot your system
reboot now
- Clone repository
cd /opt
git clone https://github.com/simatec/piler-docker.git
cd /opt/piler-docker
- start the Install
bash install-piler.sh
Congratulations your Piler is installed...
If you have Let's Encrypt activated, you can reach the Piler at https://your-piler-domain
If Let's Encrypt is disabled, the Piler is at http://your-piler-domain or at http://your-local-IP
The Default Login is admin@local and the Password ist pilerrocks
After installation, any changes can be made in piler.conf at any time and the install script can then be run again.
- Mailcow
With USE_MAILCOW=true Piler uses its built-in Mailcow support: after the IMAP login it reads the aliases
and the name of the mailbox from the Mailcow API over HTTPS. A read-only API key is enough.
If your Mailcow uses a self-signed certificate, set MAILCOW_SSL_VERIFY=false in piler.conf and restart
Piler with docker compose up -d in the install directory.
You can execute the following commands to update the containers. Here the current yml files are downloaded from Github and the containers are updated if necessary.
cd /opt/piler-docker
bash install-piler.sh
You will get a selection menu with the following options:
1) Install-Piler
2) Update-Piler
The update files are downloaded from https://raw.githubusercontent.com/simatec/piler-docker/main.
Another source can be set with the environment variable REPO_RAW_URL.
During the update the Piler image is rebuilt locally. Configuration changes required by a new
Piler version (e.g. php-fpm socket in piler-nginx.conf, pid file location, database indexes)
are applied automatically when the Piler container starts.
- After a successful update, unused container images can be removed from the system with the following command:
docker system prune
For use on the command line, we first log into the container.
docker exec -it piler /bin/bash
Next we switch to the user "piler"
su piler
To get write permissions, we switch to the /var/tmp folder
cd /var/tmp
Here you can now execute the functions of the Piler on the command line. Here are some examples:
pilerimport -h
crontab -l
To leave the container on the console you have to execute 2x exit.
- (DSTech-IT) Update to Piler 1.4.9
- (DSTech-IT) Base image Ubuntu 26.04 (resolute) with PHP 8.5, pinned by digest
- (DSTech-IT) Update MariaDB to 12.3.3 (LTS), Manticore Search to 29.9.0, Memcached to 1.6
- (DSTech-IT) Let's Encrypt: nginxproxy/nginx-proxy 1.11 and nginxproxy/acme-companion 2.8
- (DSTech-IT) Piler image is built locally, package download with SHA256 check (amd64 and arm64)
- (DSTech-IT) Piler image: install all available Ubuntu updates during the build (apt-get upgrade)
- (DSTech-IT) Automatic migration of existing configs on container start (php-fpm socket, pid file, DB indexes)
- (DSTech-IT) Fixed compose project name (piler-docker), independent of the install directory
- (DSTech-IT) Support for Docker Compose v5 in install and update scripts
- (DSTech-IT) Fix update.sh: stop the containers before the old docker-compose.yml is removed
- (DSTech-IT) update.sh rebuilds the Piler image without cache and pulls new releases of the other images
- (DSTech-IT) Fix version check in patch.sh
- (DSTech-IT) Fix Mailcow login (HTTP 500): the built-in Mailcow lookup of Piler 1.4.9 uses
ENABLE_SSL_VERIFY, which piler's config.php does not define. The Piler container now always sets it in config-site.php - (DSTech-IT) Security:
MAILCOW_HOSTnow starts withhttps://, otherwise the built-in Mailcow lookup sends the Mailcow API key over plain HTTP - (DSTech-IT) Mailcow: use the built-in Mailcow support of Piler instead of
auth-mailcow.php(patschi/mailpiler-mailcow-integration), which no longer works with Piler 1.4.9. Existing installations are switched on container start - (DSTech-IT) New option
MAILCOW_SSL_VERIFYin piler.conf (defaulttrue), set it tofalsefor a self-signed Mailcow certificate - (DSTech-IT) CI checks, Dependabot and a weekly check for new Piler, MariaDB and image versions
