To fix failing integration tests. The latest version (`1.7.4.0-r0`)
appears to not be catting all the bytes, so the expected metrics are
missing in the output.
This PR updates the tags that we generate for Envoy stats.
Several of these come with breaking changes, since we can't keep two stats prefixes for a filter.
This has the biggest impact on enterprise test cases that use namespaced
registrations, which prior to this change sometimes failed the initial
registration because the namespace was not yet created.
Added a new option `ui_config.metrics_proxy.path_allowlist`. This defaults to `["/api/v1/query", "/api/v1/query_range"]` when the metrics provider is set to `prometheus`.
Requests that do not use one of the allow-listed paths (via exact match) get a 403 Forbidden response instead.
The key thing here is to use `curl --no-keepalive` so that envoy
pre-1.15 tests will reliably use the latest listener every time.
Extra:
- Switched away from editing line-item intentions the legacy way.
- Removed some teardown scripts, as we don't share anything between cases anyway
- Removed unnecessary use of `run` in some places.
There is a delay between an intentions change being made, and it being
reflected in the Envoy runtime configuration. Now that the enforcement
happens inside of Envoy instead of over in the agent, our tests need to
explicitly wait until the xDS reconfiguration is complete before
attempting to assert intentions worked.
Also remove a few double retry loops.
This speeds up individual envoy integration test runs from ~23m to ~14m.
It's also a pre-req for possibly switching to doing the tests entirely within Go (no shell-outs).
Extend Consul’s intentions model to allow for request-based access control enforcement for HTTP-like protocols in addition to the existing connection-based enforcement for unspecified protocols (e.g. tcp).
Related changes:
- hard-fail the xDS connection attempt if the envoy version is known to be too old to be supported
- remove the RouterMatchSafeRegex proxy feature since all supported envoy versions have it
- stop using --max-obj-name-len (due to: envoyproxy/envoy#11740)
A port can be sent in the Host header as defined in the HTTP RFC, so we
take any hosts that we want to match traffic to and also add another
host with the listener port added.
Also fix an issue with envoy integration tests not running the
case-ingress-gateway-tls test.
Previously, we did not require the 'service-name.*' host header value
when on a single http service was exposed. However, this allows a user
to get into a situation where, if they add another service to the
listener, suddenly the previous service's traffic might not be routed
correctly. Thus, we always require the Host header, even if there is
only 1 service.
Also, we add the make the default domain matching more restrictive by
matching "service-name.ingress.*" by default. This lines up better with
the namespace case and more accurately matches the Consul DNS value we
expect people to use in this case.
The DNS resolution will be handled by Envoy and defaults to LOGICAL_DNS. This discovery type can be overridden on a per-gateway basis with the envoy_dns_discovery_type Gateway Option.
If a service contains an instance with a hostname as an address we set the Envoy cluster to use DNS as the discovery type rather than EDS. Since both mesh gateways and terminating gateways route to clusters using SNI, whenever there is a mix of hostnames and IP addresses associated with a service we use the hostname + CDS rather than the IPs + EDS.
Note that we detect hostnames by attempting to parse the service instance's address as an IP. If it is not a valid IP we assume it is a hostname.
The previous change, which moved test running to Go, appears to have
broken log capturing. I am not entirely sure why, but the run_tests
function seems to exit on the first error.
This change moves test teardown and log capturing out of run_test, and
has the go test runner call them when necessary.
* test/integration: only run against 1 envoy version
These tests are slow enough that it seems unlikely that anyone is
running multiple versions locally. If someone wants to, a for loop
outside of run_test.sh should do the right thing.
Remove unused vars.
* Remove logic to iterate over test cases, run a single case
* Add a golang runner for integration tests
* Use build tags for envoy integration tests
And add junit-xml report
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
- 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.
* Implements a simple, tcp ingress gateway workflow
This adds a new type of gateway for allowing Ingress traffic into Connect from external services.
