Hello,
I installed docker. And next I wanted to create and run a container by starting with a simple one:
bash-5.1# docker run hello-world
Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Get "http
s://registry-1.docker.io/v2/": dial tcp 3.94.224.37:443: connect: network is unreachable.
See 'docker run --help'
To me it looks like a registry issue. However, to my knowledge, those docker images like 'hello-world' are part of Docker Hub's public library.
I would appreciate any advice.
Thanks.
Internet access s ok since I am getting my 200 OK response
bash-5.1# curl -v https://hub.docker.com | head
