[[email protected] data-ci]# docker search gitlab-runner 
[[email protected] data-ci]# docker pull gitlab/gitlab-runner
[[email protected] data-ci]# docker run -d -v /data-ci/:/data-ci/ --restart=always --name gitlab-runner gitlab/gitlab-runner

然後註冊：

[[email protected] data-ci]# docker exec -it 80ac801e633b gitlab-runner register
Runtime platform                                    arch=amd64 os=linux pid=16 revision=cf91d5e1 version=11.4.2

這後就是gitlab報錯

然後就是發現使用者是--user=gitlab-runner

[[email protected] data-ci]# ps -ef | grep gitlab-runner
root     31028 30984  0 10:30 ?        00:00:00 /usr/bin/dumb-init /entrypoint run --user=gitlab-runner --working-directory=/home/gitlab-runner
root     31091 31028  0 10:30 ?        00:00:00 gitlab-runner run --user=gitlab-runner --working-directory=/home/gitlab-runner
root     31155 31017  0 10:30 pts/2    00:00:00 grep --color=auto gitlab-runner
 

為了解決這個問題
進入容器

[[email protected] data-ci]# docker exec -it 80ac801e633b /bin/bash
[email protected]:/# su gitlab-runner
[email protected]:/$ ssh-keygen

把密複製到遠端主機上。光這個還不行，還要在容器裡測試一下

[email protected]:/$ scp -r /data-ci/eatjoys-front.sh  [email protected]://data-ci/eatjoys-front.sh
The authenticity of host '47.99.89.247 (47.99.89.247)' can't be established.

Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '47.99.89.247' (ECDSA) to the list of known hosts.
eatjoys-front.sh

第一次，一定要輸入一下yes 才會通過， 然後看gitlab上

通過了，這樣就可以繼續下一步 寫指令碼咯~！
