This is a repository for our publicly available Docker base images.
Images prefixed with circleci- are used to boot build and test jobs in our CircleCI 2.0 workflow.
Each image inherits from circleci-base, and provides an extra set of preloaded tools for building or testing our codebase.
The .circleci/config config defines a nightly workflow (as well as on each new commit) which rebuilds all 4 images to ensure they have the latest upstream patches from the Ubuntu repos and any pulled in PPAs.
circleci-base: this base image provides all the tools required to build our codebase.circleci-fullstack: this extends the base image to include tools likeredis,rabbitmqandmailcatcherthat are required by unit and integration tests (postgresqlis provided as an extra docker container from the upstream images).circleci-fullstack-cypress: this extends the fullstack image to also include the Cypress for running end-to-end browser tests.circleci-deploy: This image is not based oncircleci-baseand is instead based on Bitnami's minideb base image to provide the smallest possible yet capable container for deploying a successful build to Heroku (ships withheroku-toolbelt).
