Base docker images for the OpenSAFELY framework. These provide a common, up to date base image to build on top of.
This repo produces two image: base-docker, and base-action.
This image is up-to-date Ubuntu 20.04 base along with common debugging tools.
(e.g. strace).
It includes a helpful script for installing apt packages in the most docker friendly space-efficient manner. Adding this and using it in this and dependent images saves over 100MB, typically.
It is rebuilt and publish weekly, so there's always a fresh base to build from.
This is built from base-docker but also include a base action entrypoint,
which supports the actions are used in OpenSAFELY's
project.yaml
This entrypoint supports invoking actions with both an explicit custom CMD or an
implicit one. i.e.
run: python:latest python myscript.py option1 option2
or run: python:latest myscript.py option1 option2
Images built from base-action can define ACTION_EXEC env var to customise the
default implicit executable used to execute.
