Docker

Docker files to ease working with PathKit and WASM.

emsdk-base

This image has an Emscripten SDK environment that can be used for compiling projects (e.g. Skia's PathKit) to WASM/asm.js.

This image is standalone and does not have any extra dependencies that make it Skia-exclusive.

It gets manually pushed anytime there's an update to the Dockerfile or relevant installed libraries.

docker build -t emsdk-base ./emsdk-base/
EMSDK_VERSION="1.38.6_jre"
docker tag emsdk-base gcr.io/skia-public/emsdk-release:$EMSDK_VERSION
docker push gcr.io/skia-public/emsdk-release:$EMSDK_VERSION

For testing the image locally, the following flow can be helpful:

docker build -t emsdk-base ./emsdk-base/
# Run bash in it to poke around and make sure things are properly installed
docker run -it emsdk-release /bin/bash
# Compile PathKit with the local image
docker run -v $SKIA_ROOT:/SRC -v $SKIA_ROOT/out/dockerpathkit:/OUT emsdk-base /SRC/infra/pathkit/docker/build_pathkit.sh

karma-chrome-tests

This image has Google Chrome and karma/jasmine installed on it, which can be used to run JS tests.

This image is standalone and does not have any extra dependencies that make it Skia-exclusive.

It gets manually pushed anytime there's an update to the Dockerfile or relevant installed libraries.

docker build -t karma-chrome-tests ./karma-chrome-tests/
# check the version of chrome with the following:
docker run karma-chrome-tests /usr/bin/google-chrome-stable --version
CHROME_VERSION="68.0.3440.106_v5"  # use v1, v2, etc for any re-spins of the container.
docker tag karma-chrome-tests gcr.io/skia-public/karma-chrome-tests:$CHROME_VERSION
docker push gcr.io/skia-public/karma-chrome-tests:$CHROME_VERSION

Of note, some versions (generally before Chrome 60) run out of space on /dev/shm when using the default Docker settings. To be safe, it is recommended to run the container with the flag --shm-size=2gb.

For testing the image locally, the following can be helpful:

docker build -t karma-chrome-tests ./karma-chrome-tests/
# Run bash in it to poke around and make sure things are properly installed
docker run -it --shm-size=2gb karma-chrome-tests /bin/bash
# Run the tests (but not capturing Gold output) with the local source repo
docker run --shm-size=2gb -v $SKIA_ROOT:/SRC karma-chrome-tests karma start /SRC/infra/pathkit/karma-docker.conf.js --single-run

gold-karma-chrome-tests

This image has Google Chrome and karma/jasmine installed on it, which can be used to run JS tests.

This image assumes the runner wants to collect the output images and JSON data specific to Skia Infra's Gold tool (image correctness).

It gets manually pushed anytime there's an update to the Dockerfile or the parent image (karma-chrome-tests).

# Run the following from $SKIA_ROOT/infra/pathkit
make gold-docker-image
# check the version of chrome with the following:
docker run gold-karma-chrome-tests /usr/bin/google-chrome-stable --version
CHROME_VERSION="68.0.3440.106_v4"  # use v1, v2, etc for any re-spins of the container.
docker tag gold-karma-chrome-tests gcr.io/skia-public/gold-karma-chrome-tests:$CHROME_VERSION
docker push gcr.io/skia-public/gold-karma-chrome-tests:$CHROME_VERSION

Of note, some versions (generally before Chrome 60) run out of space on /dev/shm when using the default Docker settings. To be safe, it is recommended to run the container with the flag --shm-size=2gb.

For testing the image locally, the following can be helpful:

# Run the following from $SKIA_ROOT/infra/pathkit
make gold-docker-image
# Run bash in it to poke around and make sure things are properly installed
docker run -it --shm-size=2gb gold-karma-chrome-tests /bin/bash
# Run the tests and collect Gold output with the local source repo
mkdir -p -m 0777 /tmp/dockergold
docker run --shm-size=2gb -v $SKIA_ROOT:/SRC -v /tmp/dockergold:/OUT gold-karma-chrome-tests /SRC/infra/pathkit/docker/test_pathkit.sh
