Docker Image Example

The provided Dockerfile builds a Docker image for SciDB 15.12. The Dockerfile follows, step by step, the instructions provided in the official documentation, SciDB Community Edition Installation Guide. See Unleashing SciDB in a Docker Container for more details.

The image is space inefficient (its size is 6GB) and does not follow the Dockerfile best practices. This image is just an example. More efficient SciDB Docker images are available in the docker-library repository.

Building the Image

The image can be built locally using:

# docker build --tag scidb .

The image installs SciDB dependencies, downloads the SciDB source code, and builds and installs SciDB. The official location for SciDB source code is on Google Drive, but because Google Drive does not provide direct access to files (for example using wget), a non-official mirror of the SciDB source in Bintray is used.

Using the Image

The image contains an ENTRYPOINT script which starts the SSH, PostgeSQL and SciDB servers. Upon exit, the script stops the SciDB and PostgreSQL servers. A container can be started from this image using:

$ docker run --tty --interactive --name scidb scidb

 * Starting PostgreSQL 9.3 database server                               [ OK ]
