我正在尝试将DinD(Docker中的Docker)与我的Gitlab-CI构建脚本一起使用,无论我进行什么更改,我始终会遇到相同的错误。我在做什么错了?

对于任何回来看看这个的人来说,这就是我如何使其工作的。在提交回购协议之前,我正在本地计算机上运行gitlab-runner进行测试。
运行命令时:
gitlab-runner exec docker django_build
无论出于何种原因,它都不使用我的配置文件。我找到了此链接:https://gitlab.com/gitlab-org/gitlab-runner/issues/1791指出您必须在命令中-docker特权。
运行后:
gitlab-runner exec docker --docker-privileged django_build
一切正常。
答案 0 :(得分:0)
仔细检查GitLab runner parameters when running docker。
尤其要确保将gitlab-runner
用户添加到docker组:
sudo usermod -aG docker gitlab-runner
从那里开始,sudo -u gitlab-runner -H docker info
应该起作用。
如果不是,请检查/etc/hosts
is mounted as a volume, as in this bug。
官方gitlab-runner documentation声明,对于DiD执行者,使用
创建一个config.toml。[[runners]]
url = "https://gitlab.com/"
token = TOKEN
executor = "docker"
[runners.docker]
tls_verify = false
image = "docker:stable"
privileged = true
但是OP发现privileged = true
没有被使用。
除非config.tml是由sudo gitlab-runner register -n... --docker-privileged
命令创建的。
如果没有,则需要gitlab-runner exec docker --docker-privileged
。
