registry should go to hub.docker but here says

Error syncing pod, skipping: failed to "StartContainer" for "POD" with ErrImagePull: "image pull failed for registry.access.redhat.com/rhel7/pod-infrastructure:latest, this may be because there are no credentials on this request. details: (open /etc/docker/certs.d/registry.access.redhat.com/redhat-ca.crt: no such file or directory)"

Why ?

Please give me solution

I met the same issue on centos 7.

yum install rhsm is not working for me giving the following output:

Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: centos.ustc.edu.cn
* extras: mirrors.zju.edu.cn
* updates: centos.ustc.edu.cn
No package rhsm available.
Error: Nothing to do

But yum install subscription-manager works well for me.

For me the file /etc/rhsm/ca/redhat-uep.pem was missing. I had to uninstall and reinstall docker/kubernetes on the minion to get the file back and it worked again. What a pain.

My environment is on CentOS Linux release 7.4.1708

And these rpms.

kubernetes-master-1.5.2-0.7.git269f928.el7.x86_64
kubernetes-1.5.2-0.7.git269f928.el7.x86_64
kubernetes-node-1.5.2-0.7.git269f928.el7.x86_64
kubernetes-client-1.5.2-0.7.git269f928.el7.x86_64
docker-1.12.6-71.git3e8e77d.el7.centos.1.x86_64
docker-client-1.12.6-71.git3e8e77d.el7.centos.1.x86_64
docker-common-1.12.6-71.git3e8e77d.el7.centos.1.x86_64

There ins no rhsm in CentOS. This post hast the alternative to rhsm for CentOS.

I encounter the same problem, and i found that i not install rhsm related software on machine, you can execute command "yum install rhsm" to solve this problem.
