用docker-compose安裝gitlab及設定(於ubuntu上)

1.安裝docker-compose
sudo curl -L https://github.com/docker/compose/releases/download/1.21.2/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
或
sudo apt install docker-compose
git config –global http.sslverify “false" (遇到下載時憑證問題可使用此指令)

2.安裝gitlab
我主要是參考https://blog.toright.com/posts/5831/%E4%B8%89%E7%A7%92%E6%95%99%E4%BD%A0%E7%94%A8-docker-%E5%AE%89%E8%A3%9D-gitlab.html此篇文章
1)於ubuntu上建目錄, ex./home/ubuntu/gitlab
2)於1)目錄上建立docker-compose.yml，內容如下

version: '3.2'
services:
 
  gitlab:
    image: gitlab/gitlab-ce:latest
    hostname: gitlab.example.com
    container_name: gitlab
    restart: always
    volumes:
      - /gitlab/config:/etc/gitlab
      - /gitlab/logs:/var/log/gitlab
      - /gitlab/data:/var/opt/gitlab
    ports:
      - 443:443
      - 80:80
    networks:
      - devel-net
 
networks:
  devel-net:

3)啟動docker container
docker-compose up -d 或
docker-compose -f “docker-compose.yml" up -d

3.執行網頁
依網路上說http://localhost可用root密碼登入，
但我登不進去，最後就直接進入gitlab container改root密碼:
docker exec -it gitlab bash
進入container後
gitlab-rails console -e production
進入rail畫面
user = User.where(id: 1).first
user.password = ‘your secret’
user.password_confirmation = ‘your secret’
user.save
exit

註1: docker-compose出現未認證的解法-匯入網站憑證檔至系統
1) 取得憑證檔
openssl s_client -showcerts -connect [registry_address]:[registry_port] < /dev/null | sed -ne ‘/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p’ > ca.crt
2) 複製憑證檔至 /usr/local/share/ca-certificates/
sudo cp ca.crt /usr/local/share/ca-certificates/
3) 執行update-ca-certificates
sudo update-ca-certificates
4) 重啟docker服務
sudo service docker restart
