create minimal environment for microservices 🍻

[tokuchar]

with Jenkinsfile and docker-compose create:

• ELK stack
• harbor
• jeager (this one maybe should be running with ELK on the same elastic)
• rabbitMQ

++stage to test if each part of the env responds correctly ;)

to run docker from jenkins (on the same docker host) whe must create DID (docker in docker) https://shisho.dev/blog/posts/docker-in-docker/

follow the instruction for debian, but you must install only docker-ce: https://docs.docker.com/engine/install/debian/ and inside root user in docker we must:

chmod 777 /var/run/docker.sock

logstash:
    container_name: logstash
    image: logstash:7.16.3
    ports:
      - '5002:5000'
      - '9600:9600'
    volumes:
      - type: bind
        source: /home/opc/jenkins_data

/home/opc/jenkins_data must be mapped in jenkins container and OCI and ports.conf must be moved by jenkins to this dir
