Host OS: CentOS Linux release 7.6.1810 (Core)
CNI and version: 0.2.0
CRI and version:
I get problem that a new container can’t connect ldap container in the same compute node server.
The both container are on the same submit (10.130.2.0/23), both container can ping gateway 10.130.2.1, and at the compute node server, I can search both MAC address in the tun0 interface.
I am quite sure the ldap container working fine as other application container server can connect to the ldap container, but the new container.
As the container I have no root password and no tools for troubleshooting, e.g. ip, netstat, tcpdump, ifconfig, etc.
How can I troubleshooting this issue? both container are in same network, same compute node, same interface on the node server (tun0), how come the new container can’t ping the ldap container with “No reply”.
