Get https://registry.access.redhat.com/v1/_ping: proxyconnect tcp: x509: cannot validate certificate for xx.xx.xx.xx because it doesn't contain any IP SANs
We are running docker in RHEL7 VM in IBM cloud. The VM is sitting behind a proxy server. We have configured docker with proper HTTP & HTTPS proxy. But while trying to pull a docker image docker pull hello-world, it is throwing the below error.
Get https://registry.access.redhat.com/v1/_ping: proxyconnect tcp: x509: cannot validate certificate for xx.xx.xx.xx because it doesn't contain any IP SANs
Any possible resolution? Is there a way to disable certificate checks in docker?
The connection to docker registry via proxy will fail if https is used. Maybe answer in the thread https://stackoverflow.com/a/51073963/3437439 may help copy the ca.crt(but I have not verified). However, adding the docker registry to insecure registries solved this error for me.
