Datomic Pro Docker Template

This Dockerfile provides a template to build a Docker image for Datomic Pro. It defines the necessary automation steps for running Datomic, while deferring all privileged, user-specific configuration to a derived image via ONBUILD instructions.

This approach makes it trivial to customize your own Dockerfile to run any supported Datomic configuration. To do so, you need only to follow these steps:

1. Create a Dockerfile that is based FROM this image
2. Create a .version file with the Datomic Pro version that should be installed.
3. Create a .credentials file containing your http user and password for downloading from my.datomic.com in the form user:pass
4. Create a config folder where your Dockerfile resides and place your Datomic transactor.properties config file(s) within it
5. Add a CMD instruction in your Dockerfile with the relative path to that file e.g. config/transactor.properties

Example Folder Structure

.
├── .credentials
├── .version
├── Dockerfile
└── config
    └── transactor.properties

Example Dockerfile

FROM simplevalue/datomic-pro-template:0.1.0
CMD ["config/transactor.properties"]

Example dev-datomic

This example shows how to start a Datomic transactor for your local development machine. It runs with Datomic's dev protocol, meaning all data will be stored on disk. Therefore you will keep the database state even when you restart your Clojure REPL (in comparison to Datomic's in-memory protocol). It also starts in a Docker container and uses the same network as your development machine, therefore you can access Datomic without defining a docker port mapping.

To make it work, copy the dev-datomic folder into your project and fill in those gaps:

• dev-datomic/config/transactor.properties enter your Datomic license-key.

• dev-datomic/.credentials enter the username and password you use to log into https://my.datomic.com/

Miscellany

The Dockerfile EXPOSES port 4334. Datomic will reside in the folder /opt/datomic. If you use Datomic's dev protocol and you want to keep the data, then mount an appropriate volume into the container, example:

docker run -v $PWD/data:/opt/datomic/data ...
