As a user of NKG with a large cluster utilizing many subdomains
I want to select the hostnames for my HTTPRoute and Gateway Listener spec using wildcard characters
So that I can easily select a set of subdomains to forward traffic to.
Acceptance
- The Route and Listener Matching is implemented as referenced below.
- If a hostname is duplicated in HTTP Route, the controller should treat the duplicates as the same hostname
- Documentation is updated
- Wildcard hostname examples is added here
- Remove FIXME
Route and Listener Matching
Empty listener hostname
empty = not set in the listener
binding hostname = the hostname that the dataplane should match on
| # |
listener hostname |
route hostname |
binding hostname |
| 1.1 |
<empty> |
foo.example.com |
foo.example.com |
| 1.2 |
<empty> |
*.example.com |
*.example.com |
Regular listener hostname
| # |
listener hostname |
route hostname |
binding hostname |
| 2.1 |
foo.example.com |
foo.example.com |
foo.example.com |
| 2.2 |
foo.example.com |
foo.example.org |
none |
| 2.3 |
foo.example.com |
*.foo.example.com |
none |
| 2.4 |
foo.example.com |
*.example.com |
foo.example.com |
Wildcard listener hostname
| # |

route hostname |
binding hostname |
| 3.1 |
*.example.com |
*.example.com |
*.example.com |
| 3.2 |
*.example.com |
foo.example.com |
foo.example.com |

none |
| 3.4 |
*.example.com |
*.com |
*.example.com |
| 3.5 |
*.example.com |
*.foo.example.com |
*.foo.example.com |
Empty list of route hostnames
| # |
listener hostname |
route hostname |
binding hostname |
| 4.1 |
example.com |
empty list |
example.com |
| 4.2 |
*.example.com |
empty list |
*.example.com |
| 4.3 |
<empty> |
