[SOLVED] Kubernetes init container sysctl changes affecting containers under the POD

Issue

I made a change to sysctl net.ipv4.tcp_keepalive_time via init container. But i can see the changes to container under POD.How does this changes in initcontainer[BusyBox] affects container of a differenent image [Linux]?

Expectation is how Kubernetes init container sysctl changes affecting containers under the POD

Solution

The value net.ipv4.tcp_keepalive_time will be same between the init container and main container inside pod as it will share network namespace. For more details please refer documentation on network namespace perspective
