# CI Overview
# -----------
#
# Each night:
#
#   A build image is created (ci_image) from `docker/Dockerfile.ci` and is
#   pushed to `quay.io/influxdb/rust:ci`. This build image is then used to run
#   the CI tasks for the day.
#
# Every commit:
#
# The CI for every PR and merge to main runs tests, fmt, lints and compiles debug binaries
#
# On main if all these checks pass it will then additionally compile in "release" mode and
# publish a docker image to quay.io/influxdb/iox:$COMMIT_SHA
#
# Manual CI Image:
#
# It is possible to manually trigger a rebuild of the image used in CI. To do this, navigate to
# https://app.circleci.com/pipelines/github/influxdata/influxdb_iox?branch=main (overriding the
# branch name if desired). Then:
# - Click "Run Pipeline" in the top-right
# - Expand "Add Parameters"
# - Add a "boolean" parameter called "ci_image" with the value true
# - Click "Run Pipeline"
#
# If you refresh the page you should see a newly running ci_image workflow
