无法从 Docker 集线器中提取 Docker 中的 Docker 图像

Question

I am using docker in Linux ol7. I have installed a docker successfully. But when I try to pull images from the docker hub I am getting the below error.

[root@xxxxx ~]# docker run hello-world

Unable to find image 'hello-world: latest' locally
docker: error during connect: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.39/images/create?fromImage=hello-world&tag=latest: EOF.
See 'docker run --help'.

Docker Version I am using - Docker version 18.09.1-ol, build e32a1bd

Answer 1

Try to pass to full docker registry offical URL, from the error it seems like it looking on host machine Docker socket docker.sock or somewhere else but not on offical registry.

docker run registry.hub.docker.com/library/hello-world

You can explore this and this to deal with registry url.
