使用docker在本地部署一個Gitlab+Jenkins
GitLab
localhost:helloworld jackzhang$ docker search gitlab
NAME DESCRIPTION STARS OFFICIAL AUTOMATED
gitlab/gitlab-ce GitLab Community Edition docker image based … 2989 [OK]
直接pull下來
localhost:helloworld jackzhang$ docker search gitlab/gitlab-ce
Pull下來之后如何運行呢闻牡？去docker hub上查一下文檔妄田，當然也可以度娘，安裝文檔一大堆
https://docs.gitlab.com/omnibus/docker/
寫個簡單的腳本驮捍，這樣就不用每次手動敲命令了
#!/bin/bash
export GITLAB_HOME=~/GITLAB_HOME/
echo $GITLAB_HOME
docker run -d --publish 443:443 --publish 80:80 --publish 22:22 \
--name gitlab \
--restart always \
--volume $GITLAB_HOME/config:/etc/gitlab:Z \
--volume $GITLAB_HOME/logs:/var/log/gitlab:Z \
--volume $GITLAB_HOME/data:/var/opt/gitlab:Z \
gitlab/gitlab-ce:latest
此處有坑疟呐，對于路徑的長度好像是有一個什么限制，原來指定volume的時候宿主機（Mac本地地址）路徑有點長东且，在啟動后循環(huán)輸出：
gitaly loop on error: socket could not be created in /var/opt/gitlab/gitaly/internal_sockets
去Google了一下启具，大概是因為路徑長度的原因，于是改回了一個較短的路徑珊泳，能夠正常啟動鲁冯。Google到的鏈接：https://gitlab.com/gitlab-org/gitaly/-/issues/2311
現(xiàn)在GitLab已經(jīng)起來了，需要改一些配置色查，可以通過gitlab運行的log中看到需要修改哪里的配置
localhost:gitlab jackzhang$ docker logs gitlab | more
Thank you for using GitLab Docker Image!
Current version: gitlab-ce=13.2.1-ce.0
Configure GitLab for your system by editing /etc/gitlab/gitlab.rb file
And restart this container to reload settings.
To do it use docker exec:
docker exec -it gitlab vim /etc/gitlab/gitlab.rb
docker restart gitlab
For a comprehensive list of configuration options please see the Omnibus GitLab readme
https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md
If this container fails to start due to permission problems try to fix it by executing:
docker exec -it gitlab update-permissions
cat: /var/opt/gitlab/gitlab-rails/VERSION: No such file or directory
docker restart gitlab
Cleaning stale PIDs & sockets
Installing gitlab.rb config...
Generating ssh_host_rsa_key...
Generating public/private rsa key pair.
按照上面的說明薯演，運行docker命令
docker exec -it gitlab vim /etc/gitlab/gitlab.rb
主要是需要修改訪問Gitlab的地址，http的和ssh的秧了，在配置文件中增加以下兩行即可
external_url 'http://192.168.1.8'
gitlab_rails['gitlab_ssh_host'] = '192.168.1.8'
此時可以通過瀏覽器訪問http://192.168.1.8加載GitLab跨扮。首次登陸需要修改root的密碼，輸入兩次密碼以更改root密碼验毡。也可以注冊新的用戶登陸后創(chuàng)建project衡创。
需要為新用戶創(chuàng)建SSH公鑰，產(chǎn)生后將其拷貝到Gitlab的設(shè)置中
localhost:gitlab jackzhang$ ssh-keygen -t rsa -C '<your email>'

Your public key has been saved in <your_rsa_file_name>.pub.

在Gitlab中點擊右上角用戶頭像的向下箭頭晶通，選擇setting璃氢，在user setting中選擇SSH keys，在右側(cè)按照提示輸入添加狮辽。
OK一也，到此我們的GitLab已經(jīng)設(shè)置完畢，project也創(chuàng)建成功隘竭，試試下載代碼吧塘秦。如果你還沒有Git的客戶端，請移步到Git的安裝步驟： https://git-scm.com/book/en/v2/Getting-Started-Installing-Git
在GitLab的project中選擇你要clone的project动看，在右上角的Clone里面選擇HTTP的下載方式尊剔，拷貝URL
#這里用localhost代替了上面的IP，因為DHCP的原因菱皆，本地IP經(jīng)常發(fā)生改變
localhost:GIT_REPO jackzhang$ git clone http://localhost/Zhang/helloworld.git
