The endpoints controller currently encodes the list of unique workload identities
referenced by all workload matched by a Service into a special data-bearing
status condition on that Service. This allows a downstream controller to avoid an
expensive watch on the ServiceEndpoints type just to get this data.
The current encoding does not lend itself well to machine parsing, which is what
the field is meant for, so this PR simplifies the encoding from:
"blah blah: " + strings.Join(ids, ",") + "."
to
strings.Join(ids, ",")
It also provides an exported utility function to easily extract this data.
The new controller caches are initialized before the DependencyMappers or the
Reconciler run, but importantly they are not populated. The expectation is that
when the WatchList call is made to the resource service it will send an initial
snapshot of all resources matching a single type, and then perpetually send
UPSERT/DELETE events afterward. This initial snapshot will cycle through the
caching layer and will catch it up to reflect the stored data.
Critically the dependency mappers and reconcilers will race against the restoration
of the caches on server startup or leader election. During this time it is possible a
mapper or reconciler will use the cache to lookup a specific relationship and
not find it. That very same reconciler may choose to then recompute some
persisted resource and in effect rewind it to a prior computed state.
Change
- Since we are updating the behavior of the WatchList RPC, it was aligned to
match that of pbsubscribe and pbpeerstream using a protobuf oneof instead of the enum+fields option.
- The WatchList rpc now has 3 alternating response events: Upsert, Delete,
EndOfSnapshot. When set the initial batch of "snapshot" Upserts sent on a new
watch, those operations will be followed by an EndOfSnapshot event before beginning
the never-ending sequence of Upsert/Delete events.
- Within the Controller startup code we will launch N+1 goroutines to execute WatchList
queries for the watched types. The UPSERTs will be applied to the nascent cache
only (no mappers will execute).
- Upon witnessing the END operation, those goroutines will terminate.
- When all cache priming routines complete, then the normal set of N+1 long lived
watch routines will launch to officially witness all events in the system using the
primed cached.
* Trigger the v1 compat exported-services controller when the v1 config entry is modified.
* Hook up exported-services config entries to the event publisher.
* Add tests to the v2 exported services shim.
* Use the local materializer trigger updates on the v1 compat exported services controller when exported-services config entries are modified.
* stop sleeping when context is cancelled
This fixes behavior introduced by hashicorp/consul#20232 where
a function was added to the iptables configuration struct. Since this
struct is actually marshalled into json by consul-k8s, we should not be
placing functions inside of it.

Update Vault/Nomad versions to ensure we're testing all the latest versions .
* Use a full EndpointRef on ComputedRoutes targets instead of just the ID
Today, the `ComputedRoutes` targets have the appropriate ID set for their `ServiceEndpoints` reference; however, the `MeshPort` and `RoutePort` are assumed to be that of the target when adding the endpoints reference in the sidecar's `ProxyStateTemplate`.
This is problematic when the target lives behind a `MeshGateway` and the `Mesh/RoutePort` used in the sidecar's `ProxyStateTemplate` should be that of the `MeshGateway` instead of the target.
Instead of assuming the `MeshPort` and `RoutePort` when building the `ProxyStateTemplate` for the sidecar, let's just add the full `EndpointRef` -- including the ID and the ports -- when hydrating the computed destinations.
* Make sure the UID from the existing ServiceEndpoints makes it onto ComputedRoutes
* Update test assertions
* Undo confusing whitespace change
* Remove one-line function wrapper
* Use plural name for endpoints ref
* Add constants for gateway name, kind and port names
NET-6653 Enabling container logs when initConsulServers fails and return an error (container logs during launch() failure)
On branch NET-6653
modified: testing/deployer/sprawl/boot.go
* Add Stop method to telemetry provider
Stop the main loop of the provider and set the config
to disabled.
* Add interface for telemetry provider
Added for easier testing. Also renamed Run to Start, which better
fits with Stop.
* Add Stop method to HCP manager
* Add manager interface, rename implementation
Add interface for easier testing, rename existing Manager to HCPManager.
* Stop HCP manager in link Finalizer
* Attempt to cleanup if resource has been deleted
The link should be cleaned up by the finalizer, but there's an edge
case in a multi-server setup where the link is fully deleted on one
server before the other server reconciles. This will cover the case
where the reconcile happens after the resource is deleted.
* Add a delete mananagement token function
Passes a function to the HCP manager that deletes the management token
that was initially created by the manager.
* Delete token as part of stopping the manager
* Lock around disabling config, remove descriptions
* Update nvmrc to use v18, next to v14 and npm to v9.6.7
* Update husky pre-commit hook to v9; updated Husky to v9; updated node version in website readme
* Updated @hashicorp/platform-cli
* Check for ACL write permissions on write
Link eventually will be creating a token, so require acl:write.
* Convert Run to Start, only allow to start once
* Always initialize HCP components at startup
* Support for updating config and client
* Pass HCP manager to controller
* Start HCP manager in link resource
Start as part of link creation rather than always starting. Update
the HCP manager with values from the link before starting as well.
* Fix metrics sink leaked goroutine
* Remove the hardcoded disabled hostname prefix
The HCP metrics sink will always be enabled, so the length of sinks will
always be greater than zero. This also means that we will also always
default to prefixing metrics with the hostname, which is what our
documentation states is the expected behavior anyway.
* Add changelog
* Check and set running status in one method
* Check for primary datacenter, add back test
* Clarify merge reasoning, fix timing issue in test
* Add comment about controller placement
* Expand on breaking change, fix typo in changelog
* Update ui server to include V2 Catalog flag
* Fix typo
* Add route and redirects for the unavailable warning
* Add qualtrics link
* Remove unneccessary check and redirect
[OG Author: michael.zalimeni@hashicorp.com, rebase needed a separate PR]
* v2: support virtual port in Service port references
In addition to Service target port references, allow users to specify a
port by stringified virtual port value. This is useful in environments
such as Kubernetes where typical configuration is written in terms of
Service virtual ports rather than workload (pod) target port names.
Retaining the option of referencing target ports by name supports VMs,
Nomad, and other use cases where virtual ports are not used by default.
To support both uses cases at once, we will strictly interpret port
references based on whether the value is numeric. See updated
`ServicePort` docs for more details.
* v2: update service ref docs for virtual port support
Update proto and generated .go files with docs reflecting virtual port
reference support.
* v2: add virtual port references to L7 topo test
Add coverage for mixed virtual and target port references to existing
test.
* update failover policy controller tests to work with computed failover policy and assert error conditions against FailoverPolicy and ComputedFailoverPolicy resources
* accumulate services; don't overwrite them in enterprise
