By default, the image runs the Buildkite Agent, however one 12# can also just start the image with a shell to debug CI failures. 13# 14# To start a Buildkite Agent, run it as: 15# $ docker run --env-file <secrets> -it $(docker build -q libcxx/utils/ci) 16# 17# The environment variables in `<secrets>` should be the ones necessary 18# to run a BuildKite agent. 19# 20# If you're only looking to run the Docker image locally for debugging a 21# build bot, see the `run-buildbot-container` script located in this directory. 22# 23# A pre-built version of this image is maintained on DockerHub as ldionne/libcxx-builder. 24# To update the image, rebuild it and push it to ldionne/libcxx-builder (which 25# will obviously only work if you have permission to do so). 26# 27# $ docker build -t ldionne/libcxx-builder libcxx/utils/ci 28# $ docker push ldionne/libcxx-builder 29# 30 31FROM ubuntu:jammy 32 33# Make sure apt-get doesn't try to prompt for stuff like our time zone, etc. 34ENV DEBIAN_FRONTEND=noninteractive 35 36# This dummy command is meant to be edited from time to time, which causes the 37# CI builders to rebuild their copy of the Docker image.
