Docker build

Use the latest docker image for use as cache Docker commands example:

npx cached-docker-build-push --image-name image-name --image-tag v1

Execute this docker commands:

docker pull image-name || exit 0
docker build --cache-from=image-name -t image-name -t image-name:v1
docker push image-name:v1
docker push image-name

Docker build with multi stage

With multi stage we need to save the builder stage for use as cache. Use the flag --cache-stage-target for define the builder stage

npx cached-docker-build-push --cache-stage-target=builder --image-name image-name --image-tag v1

Execute this docker commands:

docker pull image-name:cache-builder
docker build \
 --cache-from=image-name:cache-builder \
 --target builder \
 -t image-name:cache-builder \
 .

docker build \
 --cache-from=image-name:cache-builder \
 -t image-name \
 -t image-name:v1 \
 .

docker push image-name:cache-builder
docker push image-name:v1
docker push image-name
