OpenShift pod now fails with error when trying to write to secret volume

Solution Unverified - Updated -

Issue

  • Applications that write to secret, configMap, downwardAPI or projected volumes now fail with EROFS "Read-only filesystem"

  • Applications that mount a secret, configMap, downwardAPI or projected
    volume as /etc cannot start and receive an error like:

    "container init caused "rootfs_linux.go:54: mounting "/var/lib/docker/containers/some-id/resolv.conf"  to rootfs "/var/lib/docker/devicemapper/mnt/other-id/rootfs" at "/var/lib/docker-latest/devicemapper/mnt/other-id/rootfs/etc/resolv.conf" caused "open /var/lib/docker-latest/devicemapper/mnt/other-id/rootfs/etc/resolv.conf:  read-only file system"""'
