* docs: Removal of Consul vs ZooKeeper
Although Consul does have a KV, we are not positioning Consul as a first class KV store versus other alternatives such as etcd or Zookeeper. Will remove this since this has not been updated with further analysis since this content was created.

CatalogDestinationsOnly is a passthrough that would enable dialing
addresses outside of Consul's catalog. However, when this flag is set to
true only _connect_ endpoints for services can be dialed.
This flag is being renamed to signal that non-Connect endpoints can't be
dialed by transparent proxies when the value is set to true.
Previously if you were to follow these docs and register two external
services, you would set the Address field on the node. The second
registered service would change the address of the node for the first
service.
Now the docs explain the address key and how to register more than one
external service.
* updating hero with ecs info
* updates to hero
* Include back the Basic Hero styles
The basic hero is still used on the use case pages
* Revert the tsconfig changes
Nothing in the scope of this PR requires these changes!
* Remove the old Carousel CSS file
This is no longer needed as we're using the @hashicorp/react-hero
which comes with all the styling required for this carousel to work.
* Rename ConsulHero -> HomepageHero imports/exports
This will help prevent any confusion for future devs here -- this is a
convention we have that helps us from having to trace every import,
which helps us find the source of the component without actually having
to look at the import.
* Pin the deps
These were previously pinned to the exact version; including ^ will
allow minor & patch updates to sneak in, which normally shouldn't cause
an issue but we tend to be more conservative on dep upgrades.
* Revert unneeded changes to the document file
* Revert changes to app.js file
Not needed in the scope of this PR!
* Hard pin react-alert
* Remove unneeded css

* debug: remove the CLI check for debug_enabled
The API allows collecting profiles even debug_enabled=false as long as
ACLs are enabled. Remove this check from the CLI so that users do not
need to set debug_enabled=true for no reason.
Also:
- fix the API client to return errors on non-200 status codes for debug
endpoints
- improve the failure messages when pprof data can not be collected

* Docs for Unix Domain Sockets
There are a number of cases where a user might wish to either 1)
expose a service through a Unix Domain Socket in the filesystem
('downstream') or 2) connect to an upstream service by a local unix
domain socket (upstream).
As of Consul (1.10-beta2) we've added new syntax and support to configure
the Envoy proxy to support this
To connect to a service via local Unix Domain Socket instead of a
port, add local_bind_socket_path and optionally local_bind_socket_mode
to the upstream config for a service:
upstreams = [
{
destination_name = "service-1"
local_bind_socket_path = "/tmp/socket_service_1"
local_bind_socket_mode = "0700"
...
}
...
]
This will cause Envoy to create a socket with the path and mode
provided, and connect that to service-1
The mode field is optional, and if omitted will use the default mode
for Envoy. This is not applicable for abstract sockets. See
https://www.envoyproxy.io/docs/envoy/latest/api-v3/config/core/v3/address.proto#envoy-v3-api-msg-config-core-v3-pipe
for details
NOTE: These options conflict the local_bind_socket_port and
local_bind_socket_address options. We can bind to an port or we can
bind to a socket, but not both.
To expose a service listening on a Unix Domain socket to the service
mesh use either the 'socket_path' field in the service definition or the
'local_service_socket_path' field in the proxy definition. These
fields are analogous to the 'port' and 'service_port' fields in their
respective locations.
services {
name = "service-2"
socket_path = "/tmp/socket_service_2"
...
}
OR
proxy {
local_service_socket_path = "/tmp/socket_service_2"
...
}
There is no mode field since the service is expected to create the
socket it is listening on, not the Envoy proxy.
Again, the socket_path and local_service_socket_path fields conflict
with address/port and local_service_address/local_service_port
configuration entries.
Set up a simple service mesh with dummy services:
socat -d UNIX-LISTEN:/tmp/downstream.sock,fork UNIX-CONNECT:/tmp/upstream.sock
socat -v tcp-l:4444,fork exec:/bin/cat
services {
name = "sock_forwarder"
id = "sock_forwarder.1"
socket_path = "/tmp/downstream.sock"
connect {
sidecar_service {
proxy {
upstreams = [
{
destination_name = "echo-service"
local_bind_socket_path = "/tmp/upstream.sock"
config {
passive_health_check {
interval = "10s"
max_failures = 42
}
}
}
]
}
}
}
}
services {
name = "echo-service"
port = 4444
connect = { sidecar_service {} }
Kind = "ingress-gateway"
Name = "ingress-service"
Listeners = [
{
Port = 8080
Protocol = "tcp"
Services = [
{
Name = "sock_forwarder"
}
]
}
]

This PR adds cluster members to the metrics API. The number of members per
segment are reported as well as the total number of members.
Tested by running a multi-node cluster locally and ensuring the numbers were
correct. Also added unit test coverage to add the new expected gauges to
existing test cases.
Adds more clear indicators that the collections on the learn.hashicorp.com sites have specific instructions for single node deployments.

* Update glossary.mdx
1. Update header to the first section to "Consul Vocabulary" since these are the terms used in the context of Consul conversations.
2. Kept the header "Consul Glossary" since these are the terms useful for practitioners in the consul space.
3. Removed interlinking to terms on the same page.

Initially we were loading every potential upstream address into Envoy
and then routing traffic to the logical upstream service. The downside
of this behavior is that traffic meant to go to a specific instance
would be load balanced across ALL instances.
Traffic to specific instance IPs should be forwarded to the original
destination and if it's a destination in the mesh then we should ensure
the appropriate certificates are used.
This PR makes transparent proxying a Kubernetes-only feature for now
since support for other environments requires generating virtual IPs,
and Consul does not do that at the moment.
The only thing that needed fixing up pertained to this section of the 1.18.x release notes:
> grpc_stats: the default value for stats_for_all_methods is switched from true to false, in order to avoid possible memory exhaustion due to an untrusted downstream sending a large number of unique method names. The previous default value was deprecated in version 1.14.0. This only changes the behavior when the value is not set. The previous behavior can be used by setting the value to true. This behavior change by be overridden by setting runtime feature envoy.deprecated_features.grpc_stats_filter_enable_stats_for_all_methods_by_default.
For now to maintain status-quo I'm explicitly setting `stats_for_all_methods=true` in all versions to avoid relying upon the default.
Additionally the naming of the emitted metrics for these gRPC requests changed slightly so the integration test assertions for `case-grpc` needed adjusting.

* Use proxy outbound port from TransparentProxyConfig if provided
* If -proxy-id is provided to the redirect-traffic command, exclude any listener ports
from inbound traffic redirection. This includes envoy_prometheus_bind_addr,
envoy_stats_bind_addr, and the ListenerPort from the Expose configuration.
* Allow users to provide additional inbound and outbound ports, outbound CIDRs
and additional user IDs to be excluded from traffic redirection.
This affects both the traffic-redirect command and the iptables SDK package.
This config entry is being renamed primarily because in k8s the name
cluster could be confusing given that the config entry applies across
federated datacenters.
Additionally, this config entry will only apply to Consul as a service
mesh, so the more generic "cluster" name is not needed.
