This is useful when updating an config entry with no services, and the
expected behavior is that envoy closes all listeners and clusters.
We also allow empty routes because ingress gateways name route
configurations based on the port of the listener, so it is important we
remove any stale routes. Then, if a new listener with an old port is
added, we will not have to deal with stale routes hanging around routing
to the wrong place.
Endpoints are associated with clusters, and thus by deleting the
clusters we don't have to care about sending empty endpoint responses.
We require any non-wildcard services to match the protocol defined in
the listener on write, so that we can maintain a consistent experience
through ingress gateways. This also helps guard against accidental
misconfiguration by a user.
- Update tests that require an updated protocol for ingress gateways
This now requires some type of protocol setting in ingress gateway tests
to ensure the services are not filtered out.
- small refactor to add a max(x, y) function
- Use internal configEntryTxn function and add MaxUint64 to lib
- Validate that this cannot be set on a 'tcp' listener nor on a wildcard
service.
- Add Hosts field to api and test in consul config write CLI
- xds: Configure envoy with user-provided hosts from ingress gateways
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.
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.
