Haraka is an open source SMTP server written in Node.js which provides extremely high performance coupled with a flexible plugin system allowing Javascript programmers full access to change the behaviour of the server.
To run Haraka mail server just start the container:
docker run -d -p 25:25 instrumentisto/harakaBy default, image uses default configuration files in /etc/haraka/config/ directory. To use a custom configuration file you should mount it:
docker run -d -p 25:25 \
-v /path/to/my/smtp.ini:/etc/haraka/config/smtp.ini:ro \
instrumentisto/harakaNote! Once you've installed Haraka plugins, do not forget to enable them in /etc/haraka/config/plugins file.
NPM packaged plugins can be easily installed via HARAKA_INSTALL_PLUGINS environment variable. Specify it as comma-separated NPM packages, and the container will run npm install on its startup:
docker run -d -p 25:25 \
-v /path/to/my/plugins:/etc/haraka/config/plugins:ro \
-e HARAKA_INSTALL_PLUGINS=haraka-plugin-rcpt-postgresql,haraka-plugin-auth-enc-file@1.0 \
instrumentisto/harakaLegacy custom plugin files may be mounted directly into /etc/haraka/plugins directory:
docker run -d -p 25:25 \
-v /path/to/my-awesome-plugin.js:/etc/haraka/plugins/my-awesome-plugin.js:ro \
-v /path/to/my/plugins:/etc/haraka/config/plugins:ro \
instrumentisto/harakaAlpine packages
Some plugins (like tls) may require additional system libraries being installed. Use APK_INSTALL_PACKAGES environment variable to pre-install them on container startup:
docker run -d -p 25:25 \
-v /path/to/my/plugins:/etc/haraka/config/plugins:ro \
-e APK_INSTALL_PACKAGES=openssl \
instrumentisto/harakaThis image is based on the popular Alpine Linux project, available in the alpine official image. Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.
This variant is highly recommended when final image size being as small as possible is desired. The main caveat to note is that it does use musl libc instead of glibc and friends, so certain software might run into issues depending on the depth of their libc requirements. However, most software doesn't have an issue with this, so this variant is usually a very safe choice. See this Hacker News comment thread for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.
