Sometimes the specific mirror your container is hitting is down or the version of the OS is "End of Life" (EOL).
Error messages like "cannot download repomd.xml" usually mean your Docker container is struggling to reach external package repositories. This common hurdle occurs during the yum or dnf update process in Red Hat-based images like CentOS, Fedora, or Rocky Linux. 1. Check Network and DNS Settings
Add yum install -y ca-certificates before your update command.
Outdated certificates or incorrect system times can break the secure handshake required to download repomd.xml .
I can provide the you need to drop into your Dockerfile.
💡 Always combine yum clean all with your yum install in the same RUN layer to keep your image size small. To help you get this fixed quickly, let me know: Which base image are you using (CentOS, Rocky, etc.)? Are you on a corporate network with a firewall? Can you share the exact error log ?
If you are behind a corporate firewall, Docker needs to know how to route traffic through your proxy.
If the ping fails, specify a DNS server in your Docker run command: docker run --dns 8.8.8.8
