I installed Docker 1.12.5 on rhel-3 and deployed two containers and tried to ping to each container from the other but it hangs. Tried by creating a separate bridge network and by linking, still doesn’t work. I suspect something is wrong with selinux as I got some errors during installation like
“Re-declaration of boolean virt_sandbox_use_fusefs
Failed to create node
Bad boolean declaration at /etc/selinux/targeted/tmp/modules/100/virt/cil:159
libsemanage.semanage_direct_install_info: Overriding docker module at lower priority 100 with module at priority 400.”
has anyone else encountered this? is there a solution?
