Todo URL appears incorrect #6

Closed petermcd closed 1 year ago

When installing the todo project the Ansible script outputs the following message:

ok: [host01] => {
    "msg": "Once your Kubernetes cluster is up, you can access the todo application at http://localhost:4808                                                                                                                                 0/todo"
}

Attempting to connect to this url results in:

peter@Elk:~$ wget http://127.0.0.1:48080/todo

However adding a trailing slash makes it work:

Just realised this was caused by me using 127.0.0.1 but it was also caused by me trying the same url but replacing with my devices internal network IP in a browser. Adding the trailing slash worked in eaxh case.
