I am trying to solve one question as below :
To install a network plugin, we will go with Flannel as the default choice. For inter-host communication, we will utilize the eth0 interface.
Please ensure that the Flannel manifest includes the appropriate options for this configuration.
Refer to the official documentation for the procedure.
I ran the below command now the : Network Plugin deployed? is working fine but issue with the Is Flannel using “eth0” interface for inter-host communication ?
Below is the result every thing is up only issue with Is Flannel using “eth0” interface for inter-host communication ?
