Introducing Docker Support

On-Premise Mailsac now comes with the Dockerfiles and docker-compose.yml to get up and running in seconds usingĀ Docker.

Each Mailsac microservice can be run independently with Docker. A convenient Makefile is included alongside the Dockerfile in each service, with a sample task for running in docker (make docker-run).

Frontend API+UI example:

$ cd frontend
$ make docker-run
docker build -t mailsac/frontend .

A sample docker-compose.yml file is also included. As a result you can have a fully running set of Mailsac services without even deploying it, in seconds. It should serve as a good starting point for understanding how the services talk to each other, and setting up your own deployment using pure Docker, Docker + Ansible, or an orchestrator like Kubernetes.

The original Ansible based server deployment scripts are still included. After a few requests for Docker, it was decided to make it easier for prem customers to run themselves. Both Docker and non-Docker Ansible deployments will be supported for the foreseeable future.
