Docker Build

Note we are using DOCKER_BUILDKIT and BUILDKIT_INLINE_CACHE

# build
GO_MICRO_VERSION=v1.17.1
TYPE=service
TARGET=account
VERSION=0.0.5-SNAPSHOT
# DOCKER_REGISTRY=gcr.io
DOCKER_CONTEXT_PATH=xmlking
# docker build --force-rm=true --rm=true --no-cache \
DOCKER_BUILDKIT=1 docker build --rm \
--build-arg BUILDKIT_INLINE_CACHE=1 \
--build-arg VERSION=$VERSION \
--build-arg TYPE=${TYPE} \
--build-arg TARGET=${TARGET} \
--build-arg DOCKER_REGISTRY=${DOCKER_REGISTRY} \
--build-arg DOCKER_CONTEXT_PATH=${DOCKER_CONTEXT_PATH} \
--build-arg VCS_REF=$(git rev-parse --short HEAD) \
--build-arg BUILD_DATE=$(date -u +'%Y-%m-%dT%H:%M:%SZ') \
-t ${DOCKER_REGISTRY:+${DOCKER_REGISTRY}/}${DOCKER_CONTEXT_PATH}/${TARGET}-${TYPE}:${VERSION} .

IMANGE_NAME=${DOCKER_REGISTRY:+${DOCKER_REGISTRY}/}${DOCKER_CONTEXT_PATH}/${TARGET}-${TYPE}:${VERSION}

# push
docker push $IMANGE_NAME

# check
docker inspect  $IMANGE_NAME
# remove temp images after build
docker image prune -f
# Remove dangling images
docker rmi $(docker images -f "dangling=true" -q)
# Remove images tagged with vendor=sumo
docker rmi $(docker images -f "label=org.label-schema.vendor=sumo"  -q)
# Remove all <none> layers
docker rmi $(docker images -a|grep "<none>"|awk '$1=="<none>" {print $3}')
# list local images with digest
docker images --digests

Check if the image is using root

docker run consul:1.6.1 id consul
uid=100(consul) gid=1000(consul) groups=1000(consul),1000(consul)

Docker Run

run just for testing image...

docker run -it \
-e MICRO_SERVER_ADDRESS=0.0.0.0:8080 \
-e MICRO_BROKER_ADDRESS=0.0.0.0:10001 \
-e MICRO_REGISTRY=mdns \
-p 8080:8080 -p 10001:10001 $IMANGE_NAME

Docker Compose Run

Run complete app suite with docker-compose

docker-compose up consul
docker-compose up account-service
docker-compose up emailer-service
docker-compose up gateway
docker-compose up greeter-api

Kubernetes Run

run just for testing image in k8s...

# account-service
kubectl run --rm mytest --image=xmlking/account-service:latest \
--env="MICRO_REGISTRY=kubernetes" \
--env="MICRO_SELECTOR=static" \
--env="MICRO_SERVER_ADDRESS=0.0.0.0:8080" \
