``pw_env_setup`` reliably initializes a working environment for Pigweed, but
|
|
can take awhile to run. It intelligently caches where it can, but that caching
|
|
is designed around a particular execution environment. That environment
|
|
assumption is poor when running tests with docker. To help out teams using
|
|
docker for automated testing, the Pigweed team has a publicly-available docker
|
|
image with a cache of some of the Pigweed environment. The current tag of this
|
|
image is in ``docker/tag`` under the Pigweed checkout.
|
|
|
|
To build your own docker image, start with ``docker/Dockerfile.cache`` and
|
|
run ``docker build --file docker/Dockerfile.cache .`` from the root of your
|
|
Pigweed checkout.
|
|
|
|
To use the publicly-available docker image, run
|
|
``docker build --file docker/Dockerfile.run --build-arg from=$(cat docker/tag) .``
|
|
from the root of your Pigweed checkout. You still need to run
|
|
``. ./bootstrap.sh`` within the docker image, but it should complete much
|
|
faster than on a vanilla docker image.

We're still trying to improve this process, so if you have any ideas for

improvements please `send us a note`_.
