Install

Clone this project and create a customized deploy.env file using the deploy.env.sample file as sample:

$ git clone https://github.com/fccn/docker-educast-base.git
$ cd educast_base
$ cp deploy.env.sample deploy.env

Use your preferred editor to open the newly created deploy.env file. The following variables can be modified:

• APP_NAME - Change the image name to whatever you want (currently is set to educast_base).
• DOCKER_REPO - Define the docker repository to store the generated image.

After customizing the build you can either build the image to use it locally

make build

or create a release by building and publishing the {version} and latest tagged containers to the configured {docker_repo}.

make release

Usage

To use this image as the base for an Educast application just start the application's Dockerfile like this (if APP_NAME is not changed on deploy.env):

FROM {docker_repo}/educast_base:latest
...
