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.
The bulk of this commit is moving the LeaderRoutineManager from the agent/consul package into its own package: lib/gort. It also got a renaming and its Start method now requires a context. Requiring that context required updating a whole bunch of other places in the code.
No config entry needs a Kind field. It is only used to determine the Go type to
target. As we introduce new config entries (like this one) we can remove the kind field
and have the GetKind method return the single supported value.
In this case (similar to proxy-defaults) the Name field is also unnecessary. We always
use the same value. So we can omit the name field entirely.
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.
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.

Some TLS servers require SNI, but the Golang HTTP client doesn't
include it in the ClientHello when connecting to an IP address. This
change adds a new TLSServerName field to health check definitions to
optionally set it. This fixes#9473.
Replace the large table of tests with individual calls to run(). By using
runCase, failure messages will include the line number for the test case, as
well as a line number from the test functions.
Example:
=== FAIL: agent/config TestLoad_IntegrationWithFlags/failing_case (0.01s)
runtime_test.go:4721: case: failing case
runtime_test.go:4864: error "data_dir cannot be empty" does not contain "I expected this error"
Previous:
runtime_test.go:4864: error "data_dir cannot be empty" does not contain "I expected this error"
Without the line number to the testCase data, debugging these tests is
difficult. It is impossible to jump directly to the test case, and
difficult to find the location because of many similarly named cases.
AEInterval is overridden by NonUserSource, so there is no way for a user
to set this value. These two cases represented impossible real world
scenarios.
Instead the test is replaced with one that shows that the AEInterval can
not be set by config.
This change allows us to remove the hcltail and jsontail fields from
testCase
This commit makes a number of changes that should make
TestLoad_FullConfig easier to work with, and make the test more like
real world scenarios.
* use separate files in testdata/ dir to store the config source.
Separate files are much easier to edit because editors can syntax
highlight json/hcl, and it makes strings easier to find. Previously
trying to find strings would match strings used in other tests.
* use the exported config.Load interface instead of internal NewBuilder
and BuildAndValidate.
* remove the tail config overrides, which are only necessary with
nonZero works.
This commit reduces the interface to Load() a bit, in preparation for
unexporting NewBuilder and having everything call Load.
The three arguments are reduced to a single argument by moving the other
two into the options struct.
The three return values are reduced to two by moving the RuntimeConfig
and Warnings into a LoadResult struct.
This change allows us to re-use these functions in other places without the Builder, and makes it
more explicit about which functions can warn/error and which can not.
A golden file makes the expected value easier to work with. This change also
removes a number of shims for enterprise and replaces them with a single one
for the golden filename.
* Display a warning when rpc.enable_streaming = true is set on a client
This option has no effect when running as an agent
* Added warning when server starts with use_streaming_backend but without rpc.enable_streaming
* Added unit test
It is no safe to assumes that the mapstructure keys will contain all the keys because some config can be specified
with command line flags or literals.
This change allows us to remove the json marshal/unmarshal cycle for command line flags, which will allow
us to remove all of the hcl/json struct tags on config fields.
