목표

GitLab에서 CI/CD를 하는 것

개발 환경

HOST

Mac OS X

SERVER

Ubuntu 20.04 LTS
GitLab Version : v14.5.0
Docker version 20.10.17, build 100c701

Gitlab Runner 설치

<aside> 💡 Gitlab 버전과 Gitlab-Runner의 버전을 꼭 일치시켜주세요!

</aside>

Docker로 설치하기

docker run -d --name gitlab-runner-v14.5.0 \\
--restart always \\
--volume /srv/gitlab-runner/config:/etc/gitlab-runner: \\
--volume /var/run/docker.sock:/var/run/docker.sock \\
gitlab/gitlab-runner:v14.5.0

~~docker-compose (잘안됨)~~

#docker-compose.gitlab 파일 작성
sudo vi /opt/gopath/src/gitlab/docker-compose.gitlab.runner.yml

gitlab-runner:
 container_name: gitlab-runner
 image: 'gitlab/gitlab-runner:v14.5.0'
 restart: always
 volumes:
  - '/srv/gitlab-runner/config:/etc/gitlab-runner'
  - '/var/run/docker.sock:/var/run/docker.sock'

#docker-compose로 컨테이너 실행
docker-compose -f /opt/gopath/src/gitlab/docker-compose.gitlab.runner.yml up -d

GitLab-runner 연동하기

Gitlab project Settings -> CI/CD -> Runners

도커 접속

$ docker container exec -it gitlab-runner bash

shell이용해서 scp를 한다면 executor를 shell로 설정해준다.

Runner 등록

두 가지 방법이 존재한다.

1. 비대화식 등록

gitlab-runner register -n \
--url http://<IP> \
--registration-token <TOKEN> \
--description gitlab-runner \
--executor docker \
--docker-image docker:latest \
--docker-volumes /var/run/docker.sock:/var/run/docker.sock

옵션 설명

--url	GitLab 인스턴스 URL
--registration-token	Project 의 token
--description	설명
--executor	빌드를 실행하는 데 사용할 수 있는 여러 실행 프로그램
--docker-image	Docker를 실행 프로그램으로 선택한 경우 사용할 이미지
--docker-volumes	Docker를 실행 프로그램으로 선택한 경우 사용할 볼륨

2. 대화식 등록

gitlab-runner register
# URL
# TOKEN
# runner 이름
# 특정 Tag로 커밋시 동작
# 실행프로그램

root@207d1b9b0beb:/# gitlab-runner register
Runtime platform                                    arch=amd64 os=linux pid=30 revision=f0a95a76 version=14.5.0
Running in system-mode.

Enter the GitLab instance URL (for example, https://gitlab.com/):
https://gitlab.example.com/
Enter the registration token:
katSLz2sjkHZ21nkazYs-_6cb
Enter a description for the runner:
[207d1b9b0beb]: gitlab-runner-140
Enter tags for the runner (comma-separated):
deploy
Registering runner... succeeded                     runner=ktSLz2jk
Enter an executor: parallels, kubernetes, custom, docker, ssh, virtualbox, docker+machine, docker-ssh+machine, docker-ssh, shell:
docker
Enter the default Docker image (for example, ruby:2.6):
openjdk:11.0-jdk-oracle
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!

3. 등록 확인

초록불이 들어오면 정상적으로 된것이다!
