This commit adds the necessary changes to allow an ingress gateway to
route traffic from a single defined port to multiple different upstream
services in the Consul mesh.
To do this, we now require all HTTP requests coming into the ingress
gateway to specify a Host header that matches "<service-name>.*" in
order to correctly route traffic to the correct service.
- Differentiate multiple listener's route names by port
- Adds a case in xds for allowing default discovery chains to create a
route configuration when on an ingress gateway. This allows default
services to easily use host header routing
- ingress-gateways have a single route config for each listener
that utilizes domain matching to route to different services.
This will emit warnings about the configs not doing anything but still allow them to be parsed.
This also added the warnings for enterprise fields that we already had in OSS but didn’t change their enforcement behavior. For example, attempting to use a network segment will cause a hard error in OSS.
This is a collection of refactors that make upcoming PRs easier to digest.
The main change is the introduction of the authmethod.Identity struct.
In the one and only current auth method (type=kubernetes) all of the
trusted identity attributes are both selectable and projectable, so they
were just passed around as a map[string]string.
When namespaces were added, this was slightly changed so that the
enterprise metadata can also come back from the login operation, so
login now returned two fields.
Now with some upcoming auth methods it won't be true that all identity
attributes will be both selectable and projectable, so rather than
update the login function to return 3 pieces of data it seemed worth it
to wrap those fields up and give them a proper name.
When using namespaces, the 'default' namespace is a little special in
that we wanted the option for all our URLs to stay the same when using
namespaces if you are using the default namespace, with the option of
also being able to explicitly specify `~default` as a namespace.
In other words both `ui/services/service-name` and
`ui/~default/services/service-name` show the same thing.
This means that if you switch between OSS and Enterprise, all of your
URLs stay the same, but you can still specifically link to the default
namespace itself.
Our routing configuration is duplicated in order to achieve this:
```
- :dc
- :service
- :kv
- :edit
- :nspace
- :dc
- :service
- :kv
- :edit
```
Secondly, ember routing resolves/matches routes in the order that you specify
them, unless, its seems, when using wildcard routes, like we do in the
KV area.
When not using the wildcard routes the above routing configuration
resolves/matches a `/dc-1/kv/service` to the `dc.kv.edit` route correctly
(dc:dc-1, kv:services), that route having been configured in a higher
priority than the nspace routes.
However when configured with wildcards (required in the KV area), note
the asterisk below:
```
- :dc
:service
- :kv
- *edit
- :nspace
- :dc
- :service
- :kv
- *edit
```
Given something like `/dc-1/kv/services` the router instead matches the
`nspace.dc.service` (nspace:dc-1, dc:kv, service:services) route first even
though the `dc.kv.edit` route should still match first.
Changing the `dc.kv.edit` route back to use a non-wildcard route
(:edit instead of *edit), returns the router to match the routes in the
correct order.
In order to work around this, we catch any incorrectly matched routes
(those being directed to the nspace Route but not having a `~`
character in the nspace parameter), and then recalculate the correct
route name and parameters. Lastly we use this recalculated route to
direct the user/app to the correct route.
This route recalcation requires walking up the route to gather up all of
the required route parameters, and although this feels like something
that could already exist in ember, it doesn't seem to. We had already
done a lot of this work a while ago when implementing our `href-mut`
helper. This commit therefore repurposes that work slighlty and externalizes
it outside of the helper itself into a more usable util so we can import
it where we need it. Tests have been added before refactoring it down
to make the code easier to follow.
Also ensure that WatchSets in tests are reset between calls to watchFired.
Any time a watch fires, subsequent calls to watchFired on the same WatchSet
will also return true even if there were no changes.
