Kubernetes API server not accessible from external through IP address
on the node that api server is running, when I call curl localhost:8080/api, I see following
{
"kind": "APIVersions",
"versions": [
"v1"
],
"serverAddressByClientCIDRs": [
{
"clientCIDR": "0.0.0.0/0",
"serverAddress": "192.168.152.201:6443"
}
]
}
However, if I do curl 192.168.152.201:6443/api on same machine, I do not get anything back.
Can anyone explain why this is the case and how I can access api server externally?

It's related to routing and when you make a call 192.168.152.201 where your traffic is going to.
Could be one or multiple things, some things to check:
Does one of your physical interfaces have
192.168.152.201configured as its IP address? (ie, ensX, or ethX)What is your default route? What do you get if you type
ip route(Linux)If
192.168.152.201is not one of your physical interfaces, is it an outside service. How do you get from your default route to that?If
192.168.152.201is, in fact, one of your physical interfaces, do you have any iptables (firewall rules) preventing access to192.168.152.201:6443and not127.0.0.1:6443
