在节点上,成功:

但是当在外部机器上尝试相同的命令时,使用节点EXTERNAL_IP
(来自gcloud compute instances list
),我得到:
$ curl -Lvso /dev/null http://x.x.x.x:30000 &> result.txt &
$ cat result.txt
* Rebuilt URL to: http://x.x.x.x:30000/

* connect to x.x.x.x port 30000 failed: Connection timed out
* Failed to connect to x.x.x.x port 30000: Connection timed out
* Closing connection 0
我可以ping
成功EXTERNAL_IP
:
ping -c 2 x.x.x.x

我可以在这里做什么来暴露nodePort
外部?
