config: add agent config flag for enterprise clients to indicate they wish to join a particular partition (#10572) 2021-07-08 10:03:38 -05:00
Kyle Nusbaum 4ad13c37db command/agent: change io.Discard to ioutil.Discard 2021-06-23 11:45:40 -05:00
Daniel Nephin b93d63b8d2 cmd: remove unnecessary GatedUi
The intent of this struct was to prevent non-json output to stdout. With
the previous cleanup, this can now be done by simply changing the stdout
stream to io.Discard.

This is just one example of why passing around io.Writers for the
streams is better than the UI interface.

Daniel Nephin e207a5de05 cmd: move agent running message to logs
Previously this line was mixed up with logging, which made the output
quite ugly. Use the logger to output this message, instead of printing
directly to stdout.

This has the advantage that the message will be visible when json logs
are enabled.

Daniel Nephin 63c737017d agent: fix agent logging
Remove the leading whitespace on every log line. This was causing problems for
a customer because their logging system was interpretting the logs as a single
multi-line log.

Daniel Nephin 9f83bc97d6 cmd: remove unnecessary args to agent.New
The version args are static and passed in from the caller. Instead read
the static values in New.

The shutdownCh was never closed, so did nothing. Remove it as a field
and an arg.

Daniel Nephin fc88c28bb9 config: make config.TestLoad_FullConfig use config.Load
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.

Daniel Nephin bd545963cc config: improve the interface of Load
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.

Daniel Nephin 84642486b9 agent: extract dependency creation from New
With this change, Agent.New() accepts many of the dependencies instead
of creating them in New. Accepting fully constructed dependencies from
a constructor makes the type easier to test, and easier to change.

There are still a number of dependencies created in Start() which can
be addressed in a follow up.

Implement Client Agent Auto Config
There are a couple of things in here.

First, just like auto encrypt, any Cluster.AutoConfig RPC will implicitly use the less secure RPC mechanism.

This drastically modifies how the Consul Agent starts up and moves most of the responsibilities (other than signal handling) from the cli command and into the Agent.

Daniel Nephin b7b652e8c9 config: rename Flags to BuilderOpts
Flags is an overloaded term in this context. It generally is used to
refer to command line flags. This struct, however, is a data object
used as input to the construction.

It happens to be partially populated by command line flags, but
otherwise has very little to do with them.

Renaming this struct should make the actual responsibility of this struct
more obvious, and remove the possibility that it is confused with
command line flags.

This change is in preparation for adding additional fields to
BuilderOpts.

Daniel Nephin 5ac012dddf config: remove Args field from Flags
This field was populated for one reason, to test that it was empty.
Of all the callers, only a single one used this functionality. The rest
constructed a `Flags{}` struct which did not set Args.

I think this shows that the logic was in the wrong place. Only the agent
command needs to care about validating the args.

This commit removes the field, and moves the logic to the one caller
that cares.

Also fix some comments.

* TestLogFile is now uses t.Parallel()

* Removed unnecessary int64Val function

* Updated docs to reflect default log name for log-file

* No longer writes to data-dir and adds .log if the filename has no extension

James Nugent e96b2b8d09 Only call signal.Notify once during agent startup
Calling twice appears to have no adverse effects, however serves to

was probably introduced while resolving conflicts during the merge of
the fix for #2404.

config: return error on extra command line arguments (#3397)
The `consul agent` command was ignoring extra command line arguments
which can lead to confusion when the user has for example forgotten to
add a dash in front of an argument or is not using an `=` when setting
boolean flags to `true`. `-bootstrap true` is not the same as
`-bootstrap=true`, for example.

Since all command line flags are known and we don't expect unparsed
arguments we can return an error. However, this may make it slightly
more difficult in the future if we ever wanted to have these kinds of
arguments.

Fixes #3397
