如何使用 gitlab-runner exec docker 正確

Question

我正在嘗試在本地運行 gitlab 管道作業以進行測試和調試。 這是我所做的

1. 在我的本地機器上安裝了 gitlab-runner。
2. sudo gitlab-runner exec docker --docker-privileged --builds-dir /tmp/builds --docker-volumes /home/fox/Work/docker/core-application:/core-application Rspec

這給

Runtime platform arch=amd64 os=linux pid=632331 revision=8fa89735 version=13.6.0

然后我嘗試用本地機器上的 gitlab-runner 鏡像來做。

docker run --name=runner --privileged -t --rm -v /var/run/docker.sock:/var/run/docker.sock -v /tmp/.gitlab-runner/:/etc/gitlab-runner -v ${PWD}:${PWD} --workdir $PWD gitlab/gitlab-runner exec docker --builds-dir /tmp/builds/ Rspec

我明白了

Runtime platform arch=amd64 os=linux pid=7 revision=8fa89735 version=13.6.0
fatal: not a git repository: /home/fox/Work/docker/core-application/../.git/modules/core-application

這是 gitlab 文檔所說的內容。

如果您想將 docker 執行器與 exec 命令一起使用，請在 docker-machine shell 或 boot2docker shell 的上下文中使用它。 這是正確地將您的本地目錄 map 到 Docker 容器內的目錄所必需的。

沒有例子，我用谷歌搜索了它，但在 docker+machine 和 gitlab-runner 周圍沒有任何結果。

有人可以告訴我如何正確地做到這一點嗎？ 任何樣品？

謝謝。

您必須從 git 存儲庫/項目的根文件夾執行命令：

 $ ls -a
 ./
 ../
 .git/
 .gitignore
 .gitlab-ci.yml
 Makefile

 $ gitlab-runner exec docker <job_name>

您正在使用 docker 命令，因為 gitlab-runner 已經在后台使用了這些命令。 有關該命令的更多信息，請參閱$ gitlab-runner exec docker --help 。
