Configuration Detail

Run all docker container:

cd microservice-demo/
docker-compose -f deploy/docker-compose/docker-compose.yml up -d

Stop all docker container:

cd microservice-demo/
docker-compose -f deploy/docker-compose/docker-compose.yml down

Custom built local docker images:

catalogue: docker-compose build

user: docker-compose build

carts: GROUP=weaveworksdemos COMMIT=test ./scripts/build.sh

queue-master: GROUP=weaveworksdemos COMMIT=test ./scripts/build.sh

shipping: GROUP=weaveworksdemos COMMIT=test ./scripts/build.sh

orders: GROUP=weaveworksdemos COMMIT=test ./scripts/build.sh

payment: docker-compose build

load-test: docker build -t load-test .

front-end: make test-image

wishlists: GROUP=weaveworksdemos COMMIT=test ./scripts/build.sh

Configure custom built images to the whole application

// Stop all running containers
cd microservice-demo/
vi deploy/docker-compose/docker-compose.yml
// Change value "image" in the existing images to your custom image name
// Start all containers again

Useful docker command:

Add your account into docker group so that you don't need sudo for every docker command. Log back in after running it to effect:

sudo gpasswd -a $USER docker

View all running docker containers:

docker ps

View all images:

docker images

Remove images to prevent caching:

docker rmi -f <docker_image_id>

Tag docker image to custom name so that it is ready to push to docker hub:

docker tag <docker_image_id> <username>/<custom_image_name>

Push docker image to docker hub:

docker login (First time only)
docker push

Inspect docker images or containers:

docker inspect <docker_id>

View real time docker container memory and cpu usage:

docker stats <docker_container_name>

Change memory usage:

sudo docker update --memory <Memory_amount> <docker_container_name>
Example: sudo docker update --memory 15M dockercompose_payment_1

Change CPU usage:

sudo docker update --cpuset-cpus=<assigned_core> <docker_container_name>
Example: sudo docker update --cpuset-cpus="3-3" dockercompose_payment_1
