In current implementation of Consul, check alias cannot determine
if a service exists or not. Because a service without any check
is semantically considered as passing, so when no healthchecks
are found for an agent, the check was considered as passing.
But this make little sense as the current implementation does not
make any difference between:
* a non-existing service (passing)
* a service without any check (passing as well)
In order to make it work, we have to ensure that when a check did
not find any healthcheck, the service does indeed exists. If it
does not, lets consider the check as failing.
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 ACL.GetPolicy RPC endpoint was supposed to return the “parent” policy and not always the default policy. In the case of legacy management tokens the parent policy was supposed to be “manage”. The result of us not sending this properly was that operations that required specifically a management token such as saving a snapshot would not work in secondary DCs until they were upgraded.
Three of the checks are temporarily disabled to limit the size of the
diff, and allow us to enable all the other checks in CI.
In a follow up we can fix the issues reported by the other checks one
at a time, and enable them.
This hook replaces lib.TranslateKeys and has a number of advantages:
1. Primarily, aliases for fields are defined on the field itself, making
the aliases much easier to maintain, and more obvious to the reader.
2. TranslateKeys translation rules are not aware of structure. It could
very easily incorrectly translate a key on one struct that was intended
to be a translation rule for a completely different struct, leading
to very hard to debug errors. The hook removes the need for the
unexpected "translation rule is an empty string to indicate stop
traversal" special case.
3. TranslateKeys attempts to duplicate a bunch of tree traversal logic
that already exists in mapstructure. Using mapstructure for traversal
removes the need to traverse the entire structure multiple times, and
makes the behaviour more obvious to the reader.
This change is being made to enable a future change of replacing
PatchSliceOfMaps. TranslateKeys sits in between PatchSliceOfMaps and
mapstructure.Decode, so it must be converted to a hook first, before
PatchSliceOfMaps can be replaced by a decode hook.
Based on work done in https://github.com/hashicorp/memberlist/pull/196
this allows to restrict the IP ranges that can join a given Serf cluster
and be a member of the cluster.
Restrictions on IPs can be done separatly using 2 new differents flags
and config options to restrict IPs for LAN and WAN Serf.
The main fix here is to always union the `primary-gateways` list with
the list of mesh gateways in the primary returned from the replicated
federation states list. This will allow any replicated (incorrect) state
to be supplemented with user-configured (correct) state in the config
file. Eventually the game of random selection whack-a-mole will pick a
winning entry and re-replicate the latest federation states from the
primary. If the user-configured state is actually the incorrect one,
then the same eventual correct selection process will work in that case,
too.
The secondary fix is actually to finish making wanfed-via-mgws actually
work as originally designed. Once a secondary datacenter has replicated
federation states for the primary AND managed to stand up its own local
mesh gateways then all of the RPCs from a secondary to the primary
SHOULD go through two sets of mesh gateways to arrive in the consul
servers in the primary (one hop for the secondary datacenter's mesh
gateway, and one hop through the primary datacenter's mesh gateway).
This was neglected in the initial implementation. While everything
works, ideally we should treat communications that go around the mesh
gateways as just provided for bootstrapping purposes.
Now we heuristically use the success/failure history of the federation
state replicator goroutine loop to determine if our current mesh gateway
route is working as intended. If it is, we try using the local gateways,
and if those don't work we fall back on trying the primary via the union
of the replicated state and the go-discover configuration flags.
This can be improved slightly in the future by possibly initializing the
gateway choice to local on startup if we already have replicated state.
This PR does not address that improvement.
Fixes#7339
Currently checks of type gRPC will emit log messages such as,
2020/02/12 13:48:22 [INFO] parsed scheme: ""
2020/02/12 13:48:22 [INFO] scheme "" not registered, fallback to default scheme
Without adding full support for using custom gRPC schemes (maybe that's
right long-term path) we can just supply the default scheme as provided
by the grpc library.
Fixes https://github.com/hashicorp/consul/issues/7274
and https://github.com/hashicorp/nomad/issues/7415
* 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
* Standardize support for Tagged and BindAddresses in Ingress Gateways
This updates the TaggedAddresses and BindAddresses behavior for Ingress
to match Mesh/Terminating gateways. The `consul connect envoy` command
now also allows passing an address without a port for tagged/bind
addresses.

* ui: Tweak breadcrumb spacing for '/' separator
* Fix up the tests i.e. services per tab so we can call them all services
* ui: Misc discovery chain fixes (#7892)
1. Look for a default splitter before looking for a default resolver in

2. Delay adding svg listeners until afterRender (fixes split tooltip)
3. Make router id's consistent for highlighting default routers in when
clicking the graph
* ui: If an error occurs on the server, surface it in the notification (#7893)
* ui: Delete old unused CSS (#7909)
This commit deletes CSS that we no longer use and we definitely will not
ever use.
We also dedup all of our imports here as it turns out SASS doesn't
dedupe imports. Strangely this increases out CSS weight by ~1kb instead
of reducing but we'd rather keep things deduped as that was the
intention
* ui: Redesign - Exposed Paths (#7912)
* Add new exposed paths icons to codebase
* Redesign Exposed Paths and create copy-button hover on Composite Row
* Refactor FeedbackDialog and CopyButton
* Change this.element to use `{{ref }}` now we don't have an element
We changed this to a tagless component with an eye to moving this to a
glimmer component, without spotting that this would also remove the
`this.element` property.
This adds an equivalent using the ref modifier.

Originally we assumed all settings would be editable in the settings
page, but over time we've added thigns to localStorage that aren't user
settable settings. This means we shouldn't save all you localStorage
settings everything time only a single setting has been saved.
This change only changes the setting you've changed via the settings
page, meaning it will never update non-user-settable settings.
ACLsEnabled is always set to either true or false. .SSOEnabled is only set if you are running enterprise (the same as .NamespacesEnabled). Therefore .SSOEnabled and .NamespacesEnabled require conditionals to check their existence.
In order to avoid future confusion we moved all go-template variables to use the conditional form, and added a comment to that effect.
Tests have been added to reflect this, but they only test that the template outputs what we expect, true e2e testing here would be advantageous.
