You may need to open the firewall for port 8080 using the [console][cloud-console] or the `gcutil` tool. The following command will allow traffic from any source to instances tagged `kubernetes-minion`:
|
||||
|
||||
```shell
|
||||
$ gcutil addfirewall --allowed=tcp:8080 --target_tags=kubernetes-minion kubernetes-minion-8080
|
||||
```
|
||||
For details about limiting traffic to specific sources, see the [gcutil documentation][https://developers.google.com/compute/docs/gcutil/reference/firewall#addfirewall]
