You need Docker and Docker Compose.
1. Learn how to install Docker and Docker Compose.
Quick installation for most operation systems:
- Docker
curl -sSL https://get.docker.com/ | sh
- Docker-Compose
curl -L https://github.com/docker/compose/releases/download/$(curl -Ls https://www.servercow.de/docker-compose/latest.php)/docker-compose-$(uname -s)-$(uname -m) > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
Please use the latest Docker engine available and do not use the engine that ships with your distros repository.
2. Clone the master branch of the repository
git clone https://github.com/mailcow/mailcow-dockerized && cd mailcow-dockerized
3. Generate a configuration file. Use a FQDN (host.domain.tld) as hostname when asked.
./generate_config.sh
4. Change configuration if you want or need to.
nano mailcow.conf
If you plan to use a reverse proxy, you can, for example, bind HTTPS to 127.0.0.1 on port 8443 and HTTP to 127.0.0.1 on port 8080.
You may need to stop an existing pre-installed MTA which blocks port 25/tcp. See this chapter to learn how to reconfigure Postfix to run besides mailcow after a successful installation.
5. Pull the images and run the composer file. The parameter -d will start mailcow: dockerized detached:
docker-compose pull
docker-compose up -d
Done!
You can now access https://${MAILCOW_HOSTNAME} with the default credentials admin + password moohoo.
The database will be initialized right after a connection to MySQL can be established.
