I am trying to profile a kubernetes pod using the BCC tools. The environment is:

• minikube v1.8.0
• installed linux kernel headers installed on the host by following the steps: https://minikube.sigs.k8s.io/docs/tutorials/ebpf_tools_in_minikube/
• Spin up zlim/bcc container inside the cluster, verified that execsnoop works.

When I run "profile" inside the container, I see the BCC is working to get profile output.

However, if I run "profile -p <container pid>" using a pid of a container, the profile output comes out empty.

There are 2 ways I get the pid of a container: 1. "docker ps" followed by "docker inspect <container_id> '{{ .State.Pid }}'" 2. Directly check "ps" on the minikube console.

Any help will be appreciated. Thanks.
