docker - Docker Dind:无法连接到Docker守护程序

Question

在运行docker:dind时，我无法使用docker login命令和任何其他docker命令。

我的用例是我有一个Nexus Docker注册表，并且试图通过GitLab CI连接到此注册表。

docker run --rm -it docker:stable-dind docker login -u user -p password https://registry.mine.io

给:

Warning: failed to get default registry endpoint from daemon (Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?). Using system default: https://index.docker.io/v1/
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Answer 1

只需将--privileged添加到命令中即可。
docker run --rm -it --privileged docker:stable-dind docker login -u user -p password https://registry.mine.io
