Hi, can you tell me how to check particular port is listening inside the container by getting inside the container.

Trung Tran:

docker inspect CONTAINER_ID | grep ExposedPorts -A2
            "ExposedPorts": {
                "80/tcp": {}
            },

Trung Tran:
You should be able to find all necessary information of a docker container with docker inspect command!

#4

Sajitha:
thank you @Trung Tran. have logged inside the container and started an agent in background. so now checking through netstat -tnlp getting the output.

#5

Sajitha:
another server has to communicate to this agent. so do i need to create a service for this as well . agent is running in port 8820.

#6

Trung Tran:
Can you describe your system in high-level?

#7

Trung Tran:
You can use pod to pod communication, but the recommended way is to use service!

#8

Trung Tran:
And apply netpol on that!
