switch to overlay driver by default on newer docker versions #41

Closed jared-mackey closed 8 years ago

jared-mackey commented 8 years ago

Using the overlay driver increases build speed dramatically. My 3 minute cached docker build went to a 10 second cached docker build. Using the environment variable DOCKER_DRIVER='overlay' enables it. I know it is supported on the current Ubuntu image. I am not sure about the alpine version.

Thanks for the report. We kind of cover this in the Readme:

docker run -it \
  -e BUILDKITE_AGENT_TOKEN=xxx \
  --privileged \
  -e DIND=true \
  -e DOCKER_DAEMON_ARGS="-s overlay" \
  buildkite/agent

We'll most probably be deleting Docker from these images (#38), and provide a separate image based on it that gives you Docker inside the agent image itself… and for that we can default to overlay driver.

I'll close this for now, given we cover it in the readme.
