In addition to exposing compilation over the API cleaned up the structures that would be exchanged to be cleaner and easier to support and understand.
Also removed ability to configure the envoy OverprovisioningFactor.
This should make them better for sending over RPC or the API.
Instead of a chain implemented explicitly like a linked list (nodes
holding pointers to other nodes) instead switch to a flat map of named
nodes with nodes linking other other nodes by name. The shipped
structure is just a map and a string to indicate which key to start
from.
Other changes:
* inline the compiler option InferDefaults as true
* introduce compiled target config to avoid needing to send back
additional maps of Resolvers; future target-specific compiled state
can go here
* move compiled MeshGateway out of the Resolver and into the
TargetConfig where it makes more sense.
* connect: reconcile how upstream configuration works with discovery chains
The following upstream config fields for connect sidecars sanely
integrate into discovery chain resolution:
- Destination Namespace/Datacenter: Compilation occurs locally but using
different default values for namespaces and datacenters. The xDS
clusters that are created are named as they normally would be.
- Mesh Gateway Mode (single upstream): If set this value overrides any
value computed for any resolver for the entire discovery chain. The xDS
clusters that are created may be named differently (see below).
- Mesh Gateway Mode (whole sidecar): If set this value overrides any
value computed for any resolver for the entire discovery chain. If this
is specifically overridden for a single upstream this value is ignored
in that case. The xDS clusters that are created may be named differently
(see below).
- Protocol (in opaque config): If set this value overrides the value
computed when evaluating the entire discovery chain. If the normal chain
would be TCP or if this override is set to TCP then the result is that
we explicitly disable L7 Routing and Splitting. The xDS clusters that
are created may be named differently (see below).
- Connect Timeout (in opaque config): If set this value overrides the
value for any resolver in the entire discovery chain. The xDS clusters
that are created may be named differently (see below).
If any of the above overrides affect the actual result of compiling the
discovery chain (i.e. "tcp" becomes "grpc" instead of being a no-op
override to "tcp") then the relevant parameters are hashed and provided
to the xDS layer as a prefix for use in naming the Clusters. This is to
ensure that if one Upstream discovery chain has no overrides and
tangentially needs a cluster named "api.default.XXX", and another
Upstream does have overrides for "api.default.XXX" that they won't
cross-pollinate against the operator's wishes.
Fixes#6159
* Add integration test for central config; fix central config WIP
* Add integration test for central config; fix central config WIP
* Set proxy protocol correctly and begin adding upstream support
* Add upstreams to service config cache key and start new notify watcher if they change.
This doesn't update the tests to pass though.
* Fix some merging logic get things working manually with a hack (TODO fix properly)
* Simplification to not allow enabling sidecars centrally - it makes no sense without upstreams anyway
* Test compile again and obvious ones pass. Lots of failures locally not debugged yet but may be flakes. Pushing up to see what CI does
* Fix up service manageer and API test failures
* Remove the enable command since it no longer makes much sense without being able to turn on sidecar proxies centrally
* Remove version.go hack - will make integration test fail until release
* Remove unused code from commands and upstream merge
* Re-bump version to 1.5.0
* Add HTTP endpoints for config entry management
* Finish implementing decoding in the HTTP Config entry apply endpoint
* Add CAS operation to the config entry apply endpoint
Also use this for the bootstrapping and move the config entry decoding function into the structs package.
* First pass at the API client for the config entries
* Fixup some of the ConfigEntry APIs
Return a singular response object instead of a list for the ConfigEntry.Get RPC. This gets plumbed through the HTTP API as well.
Dont return QueryMeta in the JSON response for the config entry listing HTTP API. Instead just return a list of config entries.
* Minor API client fixes
* Attempt at some ConfigEntry api client tests
These don’t currently work due to weak typing in JSON
* Get some of the api client tests passing
* Implement reflectwalk magic to correct JSON encoding a ProxyConfigEntry
Also added a test for the HTTP endpoint that exposes the problem. However, since the test doesn’t actually do the JSON encode/decode its still failing.
* Move MapWalk magic into a binary marshaller instead of JSON.
* Add a MapWalk test
* Get rid of unused func
* Get rid of unused imports
* Fixup some tests now that the decoding from msgpack coerces things into json compat types
* Stub out most of the central config cli
Fully implement the config read command.
* Basic config delete command implementation
* Implement config write command
* Implement config list subcommand
Not entirely sure about the output here. Its basically the read output indented with a line specifying the kind/name of each type which is also duplicated in the indented output.
* Update command usage
* Update some help usage formatting
* Add the connect enable helper cli command
* Update list command output
* Rename the config entry API client methods.
* Use renamed apis
* Implement config write tests
Stub the others with the noTabs tests.
* Change list output format
Now just simply output 1 line per named config
* Add config read tests
* Add invalid args write test.
* Add config delete tests
* Add config list tests
* Add connect enable tests
* Update some CLI commands to use CAS ops
This also modifies the HTTP API for a write op to return a boolean indicating whether the value was written or not.
* Fix up the HTTP API CAS tests as I realized they weren’t testing what they should.
* Update config entry rpc tests to properly test CAS
* Fix up a few more tests
* Fix some tests that using ConfigEntries.Apply
* Update config_write_test.go
* Get rid of unused import
