config.yml

# This CircleCI configuration executes 3 different jobs:
#   * build: Install dependencies and build static assets
#   * test: Run all unit and functional tests
#   * deploy: Push artifact code to a remote git repository.
#
# In this configuration, deployment happens regardless of testing outcome.
# Assuming you wait until tests pass before merging any PRs or deploying from dev
# to prod, this enables much faster local -> multidev deployment cycles without
# increasing risk.
#
# This configuration depends on the following environment variables being exported from
# the UI:
#
#   * TERMINUS_MACHINE_TOKEN
#
# It also depends on the following environment variables declared in docker/drupal.env:
#
#   * TERMINUS_SITE
#   * TERMINUS_SOURCE_ENVIRONMENT
#
