Microservice Application Skeleton

Yii2 console application used to write our processors of methods to responsible to client calling.

This application a template for microservice application and implement four methods of jafaripur/php-microservice. Another library created for using this microservice methods jafaripur/php-microservice-user-service.

For consuming and receiving data:

php yii_dev user-service/listen

For sending tests messages, By using this client library (jafaripur/php-microservice-user-service):

php yii_dev user-service/send-test

Create project

composer create-project "jafaripur/php-microservice-application-yii2 dev-master" micro3

Configuration

Three env file exist:

.env        => For production
.env_dev    => For development
.env_test   => For test with codeception

Three entrypoint:

yii        => For production
yii_dev    => For development
yii_test   => For test with codeception

Production Build

This application can be run with roadrunner service plugin in production with Dockerfile docker/Dockerfile.prod, Production build with docker:

export DOCKER_BUILDKIT=1 && docker build -f "./docker/Dockerfile.prod" -t "micro3-prod:latest" .

After building, we can create a container or docker swarm service. The production docker image runs with RoadRunner. In this example we use this configuration for RoadRunner, config exist in .rr.yaml file.

version: "2.7"

service:
  topics:
    command: "php yii user-service/listen first-consumer"
    process_num: 10
    exec_timeout: 0
    remain_after_exit: true
    restart_sec: 5

  emits:
    command: "php yii user-service/listen second-consumer"
    process_num: 2
    exec_timeout: 0
    remain_after_exit: true
    restart_sec: 5

logs:
  mode: production
  encoding: console

With this RoadRunner service plugin we can run several consumer with several instance.

For creating docker container from builded image:

docker run -d --init \
    --name micro3-container \
    --restart unless-stopped \
    micro3-prod:latest

And for swarm service:

docker service create --name "micro3-service" \
    --replicas 2 \
    --update-delay 10s \
    micro3-prod:latest

Test

# Run test
docker-compose up --build micro

# Stop and remove created containers
docker-compose down
