Objective: Create the smallest possible Docker image for Pharo for running headless, batch and server-side applications.
Approach:
-
Use Alpine Linux as base image for the Pharo VM Docker image. This requires building the Pharo VM to run on Alpine Linux. See
vm.buildfor the howto. -
Reduce the size of the Pharo VM for Alpine Linux, by removing irrelevant built-in and external plugins.
-
Reduce the size of the application Pharo image, by starting from the minimal Pharo image or making use of new bootstrapping techniques.
