freddygv 739490df12 handle error scenario of empty local DC 2021-11-09 16:42:42 -07:00
freddygv b9b41625b9 Restrict DC for partition-exports writes
There are two restrictions:
- Writes from the primary DC which explicitly target a secondary DC.
- Writes to a secondary DC that do not explicitly target the primary DC.

The first restriction is because the config entry is not supported in
secondary datacenters.

The second restriction is to prevent the scenario where a user writes
the config entry to a secondary DC, the write gets forwarded to the
primary, but then the config entry does not apply in the secondary.
This makes the scope more explicit.

Daniel Nephin 047abdd73c acl: remove ACLDatacenter
This field has been unnecessary for a while now. It was always set to the same value
as PrimaryDatacenter. So we can remove the duplicate field and use PrimaryDatacenter
directly.

This change was made by GoLand refactor, which did most of the work for me.

server: ensure that central service config flattening properly resets the state each time (#10239)
The prior solution to call reply.Reset() aged poorly since newer fields
were added to the reply, but not added to Reset() leading serial
blocking query loops on the server to blend replies.

This could manifest as a service-defaults protocol change from
default=>http not reverting back to default after the config entry
reponsible was deleted.

connect: update centralized upstreams representation in service-defaults (#10015) 2021-04-15 14:21:44 -05:00
freddygv eeccba945d Replace TransparentProxy bool with ProxyMode
This PR replaces the original boolean used to configure transparent
proxy mode. It was replaced with a string mode that can be set to:

- "": Empty string is the default for when the setting should be
defaulted from other configuration like config entries.
- "direct": Direct mode is how applications originally opted into the
mesh. Proxy listeners need to be dialed directly.
- "transparent": Transparent mode enables configuring Envoy as a
transparent proxy. Traffic must be captured and redirected to the
inbound and outbound listeners.

This PR also adds a struct for transparent proxy specific configuration.
Initially this is not stored as a pointer. Will revisit that decision
before GA.

freddygv a1fd3b0271 Pass down upstream defaults to client proxies
This is needed in case the client proxy is in TransparentProxy mode.
Typically they won't have explicit configuration for every upstream, so
this ensures the settings can be applied to all of them when generating
xDS config.

freddygv 04fbc104cd Pass MeshGateway config in service config request
ResolveServiceConfig is called by service manager before the proxy
registration is in the catalog. Therefore we should pass proxy
registration flags in the request rather than trying to fetch
them from the state store (where they may not exist yet).

connect: intentions are now managed as a new config entry kind "service-intentions" (#8834)
- Upgrade the ConfigEntry.ListAll RPC to be kind-aware so that older
copies of consul will not see new config entries it doesn't understand
replicate down.

- Add shim conversion code so that the old API/CLI method of interacting
with intentions will continue to work so long as none of these are
edited via config entry endpoints. Almost all of the read-only APIs will
continue to function indefinitely.

- Add new APIs that operate on individual intentions without IDs so that
the UI doesn't need to implement CAS operations.

- Add a new serf feature flag indicating support for
intentions-as-config-entries.

- The old line-item intentions way of interacting with the state store
will transparently flip between the legacy memdb table and the config
entry representations so that readers will never see a hiccup during
migration where the results are incomplete. It uses a piece of system
metadata to control the flip.

- The primary datacenter will begin migrating intentions into config
entries on startup once all servers in the datacenter are on a version
of Consul with the intentions-as-config-entries feature flag. When it is
complete the old state store representations will be cleared. We also
record a piece of system metadata indicating this has occurred. We use
this metadata to skip ALL of this code the next time the leader starts
up.

- The secondary datacenters continue to run the old intentions
replicator until all servers in the secondary DC and primary DC support
intentions-as-config-entries (via serf flag). Once this condition it met
the old intentions replicator ceases.

- The secondary datacenters replicate the new config entries as they are
migrated in the primary. When they detect that the primary has zeroed
it's old state store table it waits until all config entries up to that
point are replicated and then zeroes its own copy of the old state store
table. We also record a piece of system metadata indicating this has
occurred. We use this metadata to skip ALL of this code the next time
the leader starts up.

Freddy 5eace88ce2
Expose HTTP-based paths through Connect proxy (#6446)
Fixes: #5396

This PR adds a proxy configuration stanza called expose. These flags register
listeners in Connect sidecar proxies to allow requests to specific HTTP paths from outside of the node. This allows services to protect themselves by only
listening on the loopback interface, while still accepting traffic from non
Connect-enabled services.

Under expose there is a boolean checks flag that would automatically expose all
registered HTTP and gRPC check paths.

This stanza also accepts a paths list to expose individual paths. The primary
use case for this functionality would be to expose paths for third parties like
Prometheus or the kubelet.

Listeners for requests to exposed paths are be configured dynamically at run
time. Any time a proxy, or check can be registered, a listener can also be
created.

In this initial implementation requests to these paths are not
authenticated/encrypted.

connect: updating a service-defaults config entry should leave an unset protocol alone (#6342)
If the entry is updated for reasons other than protocol it is surprising
that the value is explicitly persisted as 'tcp' rather than leaving it
empty and letting it fall back dynamically on the proxy-defaults value.

* 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

Matt Keeler ea6cbf01a5 Centralized Config CLI (#5731)
* 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
