Getting Started

1. Install Docker Engine

It works with Windows / macOS / Linux (Ubuntu preferred)..

Carl Boettiger suggests that Docker "could have promising implications for reproducible research in scientific communities" despite challenges like adoption by the scientific community. (arxiv).

2. Install Docker-Compose

NOTE: The previous step may have included the docker-compose binary depending on your operating system.

3. Clone this Repository

click to expand

git clone https://github.com/mfekadu/nimbus

4. Create the .env file with the following secrets

The .env file is read by docker-compose (from current working directory) to string-replace the variables in the docker-compose.yml file.

See the .env_sample

TODOs:

• make actions image a variable and put in .env_sample

4.5. Resources for Docker Desktop on (macOS / Windows)

Sorry that this system is resource intensive. There may be room for optimization!

5. Run all the services

The following command will download/cache/install/build -- do everything to set up the infrastructure and run the program.

Run the following command in the root of the directory for this codebase:

docker-compose up --detach

NOTE: run with sudo if need be on Linux/macOS

NOTE: Grab a coffee or some snacks. The various downloads will take some time, but docker will cache each stage of the build, so things will be faster next time.
