./with_dockerfile --verbose make lint
mkdir -p ./tmp/with_dockerfile_exmaple
echo "FROM busybox" > ./tmp/with_dockerfile_exmaple/Dockerfile

./with_dockerfile --verbose --build-path ./tmp/with_dockerfile_exmaple ls -lh

Run command on container and copy artifacts from docker volume to host directory.

mkdir -p ./tmp/with_dockerfile_exmaple
echo "FROM busybox" > ./tmp/with_dockerfile_exmaple/Dockerfile

./with_dockerfile --verbose --build-path ./tmp/with_dockerfile_exmaple \
  --task-id 'ls' --artifact out.txt sh -c 'ls -lh > out.txt'

cat ./artifacts/ls/out.txt

Use docker volume as cache.

mkdir -p ./tmp/with_dockerfile_exmaple
echo "FROM node:current-alpine" > ./tmp/with_dockerfile_exmaple/Dockerfile

./with_dockerfile --verbose --build-path ./tmp/with_dockerfile_exmaple \
  --task-id 'node-example' --run-opts '-v npm-user-cache:/root/.npm' \
  sh -c 'npm install ramda; ls -lh ./node_modules'

Git

Run command when branch is pushed.

cat > ./tmp/hooks.ltsv << 'HOOKS'
