Slack App 을 등록하고, 알림을 전송할 수 있는 프로젝트
Slack App 을 등록하는 방법 참고


Eureka 등록

현재 Eureka 가 띄워진 곳은 gcloud(239, 240)
서로 사설 IP로 통신하기 위해 각각 사설 IP를 알고 있어야 함.

yml 설정 파일

eureka:
  instance:
    prefer-ip-address: true
    ip-address: [HOST_IP]
  client:
    register-with-eureka: true
    fetch-registry: true
    service-url:
      defaultZone: http://[GCLOUD_239_사설_IP]:8761/eureka, http://GCLOUD_240_사설_IP:8761/eureka
  • eureka.instance.ip-address: Slack-Service 가 Eureka 에 등록할(Endpoint) IP 작성
  • eureka.client.service-url.defaultZone: Eureka 가 띄워져 있는 IP 작성

.gitlab-ci.yml 추가 설정

Slack instance 를 띄우고자하는 gcloud 서버마다 gitlab runner 등록
본 서비스는 gcloud(238, 239, 240) 서버에 띄우고자 하며, 3개 등록 되어있음

.gitlab-ci.yml 파일 설정

g238_deploy:
  stage: deploy
  tags:
    - g238
  script:
    - docker pull $DOCKER_HUB_ID/$IMAGE_NAME
    - "{ docker stop $CONTAINER_NAME; docker rm $CONTAINER_NAME; } || true"
    - "docker run -d -p $SLACK_SERVICE_PORT:$SLACK_SERVICE_PORT \
    --name $CONTAINER_NAME \
    -e HOST_IP=$HOST_238_IP \
    -e CONFIG_SERVER_URL=$CONFIG_SERVER_URL \
    $DOCKER_HUB_ID/$IMAGE_NAME"

g239_deploy:
  stage: deploy
  tags:
    - g239
  script:
    - docker pull $DOCKER_HUB_ID/$IMAGE_NAME
    - "{ docker stop $CONTAINER_NAME; docker rm $CONTAINER_NAME; } || true"
    - "docker run -d -p $SLACK_SERVICE_PORT:$SLACK_SERVICE_PORT \

g240_deploy:
  stage: deploy
  tags:
    - g240
  script:
    - docker pull $DOCKER_HUB_ID/$IMAGE_NAME

    -e HOST_IP=$HOST_240_IP \
    -e CONFIG_SERVER_URL=$CONFIG_SERVER_URL \
    $DOCKER_HUB_ID/$IMAGE_NAME"
  • 사전에 gcloud (238, 239, 240) 서버에 gitlab runner 를 등록 할 때, tag 를 입력하고 runner 를 생성해야 함
  • $HOST_238_IP, $HOST_239_IP, $HOST_240_IP 정보를 gitlab runner secret variable 로 주입 받음

Gitlab runner tag Docs

$ gitlab-runner register -n \
      --url https://gitlab.gabia.com/ \
      --registration-token [TOKEN] \
      --executor docker \
      --description "gitlab-runner on 240" \
      --tag-list "g240" \
      --docker-image "docker:19.03.12" \
      --docker-volumes /var/run/docker.sock:/var/run/docker.sock
  • --tag-list 옵션을 사용해서 tag 를 붙임
