Microservices

How it works#

We introduced such a concept as a service group. A service group is an agent set of microservice applications. To combine agents into a service group, you need to add only one more parameter to start the agent - groupId.

After that, your application looks like a monolith for testing with Drill4J and you need to use groupId instead of agentId for autotests here.

Chrome browser extension detects service groups automatically.

Docker-compose file for your application may look like this:

version: '2'

services:

  some-non-jvm-service:
    image: repo/some-non-jvm-service:3.1.0
    ports:
      - 8082:8082

  some-jvm-service-one:
    image: repo/some-jvm-service-two:0.1.0
    ports:
      - 8080:8080
    volumes:
      - ./distr:/data
    environment:
      - JAVA_OPTS=-agentpath:/data/libdrill_agent.so=drillInstallationDir=/data,adminAddress=host.docker.internal:8090,agentId=service-one,groupId=app,buildVersion=0.1.0,logLevel=INFO

  some-jvm-service-two:
    image: repo/some-jvm-service-one:0.2.1
    ports:
      - 8081:8081
    volumes:
      - ./distr:/data
    environment:
      - JAVA_OPTS=-agentpath:/data/libdrill_agent.so=drillInstallationDir=/data,adminAddress=host.docker.internal:8090,agentId=service-two,groupId=app,buildVersion=0.2.1,logLevel=INFO

After launching the application you can see your Microservice app in Drill Admin:
