You'd better check the connectivity of the debug agent address:port, which supplies 172.168.45.169:10027 above.

@fralychen @thetruechar What's the output of kubectl debug --version? It should have created the debug agent automatically on launch in after v1.0.1
@aylei @thetruechar It's fine for:
kubectl-debug --agentless --port-forward myapp -n default
brew install 7 days ago.
❯ kubectl debug --version
debug version v0.0.0-master+$Format:%h$
brew install aylei/tap/kubectl-debug
Updating Homebrew...
^CWarning: aylei/tap/kubectl-debug 0.1.1 is already installed and up-to-date
[root@localhost ~]# kubectl-debug --version debug version v0.0.0-master+$Format:%h$
@fralychen @thetruechar
It turns out that v0.1.1 does have --agentless and --port-forward by default, so you must command --agentless explicitly if the agent is not installed in advance and command --port-forward explicitly if the 10027 port of the target node is not directly accessible.
An alternative is to configure the default value of these options in a local configuration file https://github.com/aylei/kubectl-debug#configuration, or you can upgrade to v0.2.0-rc via brew upgrade aylei/tap/kubectl-debug.
