Docker images

These images describe a pre-set-up environment for building Please in as well as various auxiliary images as well. Currently we only have one build image for Ubuntu which is the canonical build environment on Linux; in future it'd be nice to add more (e.g. Alpine) once we can support them.

Note that various dependencies can be seen as more or less optional (for example there are three Python engines, of which any one is needed for Please to work). The aspiration is to build all features in each image, but some may be harder than others if certain packages aren't available.

Updating images

Once you have made your changes, there are 4 steps to publish them:

• Ensure your docker daemon is running and you're logged into docker hub
• Run docker build . in the directory of the image you want to build. Docker will print out the image ID at the end: Successfully built ac1817b4fc9e
• Run docker tag ac1817b4fc9e thoughtmachine/please_ubuntu:20210720 replacing the image ID with yours, and the tag with todays date in YYYYMMDD format. NB. replace please_ubuntu based on the image you're building.
• Run docker push thoughtmachine/please_ubuntu:2021072020 to push to the remote repo, replacing your image and tag to match the above command. Make sure you've done a docker login to the docker hub registry.
