* Add function to get update channel for watching HCP Link
* Add MonitorHCPLink function
This function can be called in a goroutine to manage the lifecycle
of the HCP manager.
* Update HCP Manager config in link monitor before starting
This updates HCPMonitorLink so it updates the HCP manager
with an HCP client and management token when a Link is upserted.
* Let MonitorHCPManager handle lifecycle instead of link controller
* Remove cleanup from Link controller and move it to MonitorHCPLink
Previously, the Link Controller was responsible for cleaning up the
HCP-related files on the file system. This change makes it so
MonitorHCPLink handles this cleanup. As a result, we are able to remove
the PlacementEachServer placement strategy for the Link controller
because it no longer needs to do this per-node cleanup.
* Remove HCP Manager dependency from Link Controller
The Link controller does not need to have HCP Manager
as a dependency anymore, so this removes that dependency
in order to simplify the design.
* Add Linked prefix to Linked status variables
This is in preparation for adding a new status type to the
Link resource.
* Add new "validated" status type to link resource
The link resource controller will now set a "validated" status
in addition to the "linked" status. This is needed so that other
components (eg the HCP manager) know when the Link is ready to link
with HCP.
* Fix tests
* Handle new 'EndOfSnapshot' WatchList event
* Fix watch test
* Remove unnecessary config from TestAgent_scadaProvider
Since the Scada provider is now started on agent startup
regardless of whether a cloud config is provided, this removes
the cloud config override from the relevant test.
This change is not exactly related to the changes from this PR,
but rather is something small and sort of related that was noticed
while working on this PR.
* Simplify link watch test and remove sleep from link watch
This updates the link watch test so that it uses more mocks
and does not require setting up the infrastructure for the HCP Link
controller.
This also removes the time.Sleep delay in the link watcher loop in favor
of an error counter. When we receive 10 consecutive errors, we shut down
the link watcher loop.
* Add better logging for link validation. Remove EndOfSnapshot test.
* Refactor link monitor test into a table test
* Add some clarifying comments to link monitor
* Simplify link watch test
* Test a bunch more errors cases in link monitor test
* Use exponential backoff instead of errorCounter in LinkWatch
* Move link watch and link monitor into a single goroutine called from server.go
* Refactor HCP link watcher to use single go-routine.
Previously, if the WatchClient errored, we would've never recovered
because we never retry to create the stream. With this change,
we have a single goroutine that runs for the life of the server agent
and if the WatchClient stream ever errors, we retry the creation
of the stream with an exponential backoff.
* 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
* 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
* Move config-dependent methods to separate package
In order to reuse the fetching and file creation part of the
bootstrap package, move the code that would cause cyclical
dependencies to a different package.
* Export needed bootstrap methods and variables
Also add back validating persisted config and update tests.
* Add support to check for just management token
Add a new method that fetches the bootstrap configuration only if
there isn't a valid management token file instead of checking for
all the hcp-config files.
* Pass data dir as a dependency to link controller
The link controller needs to check the data directory for
the hcp-config files.
* Fetch bootstrap config for token in controller
Load the management token when reconciling a link resource, which will
fetch the agent boostrap configuration if the token is not already
persisted locally. Skip this step if the cluster is in read-only mode.
* Validate resource ID format in link creation
* Handle unauthorized and forbidden errors
Check for 401 and 403s when making GNM requests, exit bootstrap fetch
loop and return specific failure statuses for link.
* Move test function to a testing file
* Log load and status write errors
* Add Initializer to the controller
The Initializer adds support for running any required initialization
steps when the controller is first started.
* Implement HCP Link initializer
The link initializer will create a Link resource if the
cloud configuration has been set.
* Simplify retry logic and testing
* Remove internal retry, replace with logging logic
* Add HCCLink resource type
* Register HCCLink resource type with basic validation
* Add validation for required fields
* Add test for default ACLs
* Add no-op controller for HCCLink
* Add resource-apis semantic validation check in hcclink controller
* Add copyright headers
* Rename HCCLink to Link
* Add hcp_cluster_url to link proto
* Update 'disabled' reason with more detail
* Update link status name to consul.io/hcp/link
* Change link version from v1 to v2
* Use feature flag/experiment to enable v2 resources with HCP
