Move all the gossip keyring and key generation commands under
`operator gossip keyring` subcommands to align with the new `operator
secure-variables keyring` subcommands. Deprecate the `operator keyring`
and `operator keygen` commands.
Split the flag options for the `secure-variables keyring` into their
own subcommands. The gossip keyring CLI will be similarly refactored
and the old version will be deprecated.
* core: allow pause/un-pause of eval broker on region leader.
* agent: add ability to pause eval broker via scheduler config.
* cli: add operator scheduler commands to interact with config.
* api: add ability to pause eval broker via scheduler config
* e2e: add operator scheduler test for eval broker pause.
* docs: include new opertor scheduler CLI and pause eval API info.
The `nomad operator raft` and `nomad operator snapshot state`
subcommands for inspecting on-disk raft state were hidden and
undocumented. Expose and document these so that advanced operators
have support for these tools.
Use the new filtering and pagination capabilities of the `Eval.List`
RPC to provide filtering and pagination at the command line.
Also includes note that `nomad eval status -json` is deprecated and
will be replaced with a single evaluation view in a future version of
Nomad.
Add new commands for creating, deleting, and listing external storage
volumes. Includes HCL decoding update for volume spec so that we can humanize
capacity bytes input values.
Create a convenience command for generating example CSI volume specifications,
similar to the existing `nomad job init` or `nomad quota init` commands.
* Remove Managed Sinks from Nomad
Managed Sinks were a beta feature in Nomad 1.0-beta2. During the beta
period it was determined that this was not a scalable approach to
support community and third party sinks.
* update comment
* changelog
The soundness guarantees of the CSI specification leave a little to be desired
in our ability to provide a 100% reliable automated solution for managing
volumes. This changeset provides a new command to bridge this gap by providing
the operator the ability to intervene.
The command doesn't take an allocation ID so that the operator doesn't have to
keep track of alloc IDs that may have been GC'd. Handle this case in the
unpublish RPC by sending the client RPC for all the terminal/nil allocs on the
selected node.

The system command includes gc and reconcile-summaries subcommands
which covers all currently available system API calls. The help
information is largely pulled from the current Nomad website API
documentation.
Adds nomad monitor command. Like consul monitor, this command allows you
to stream logs from a nomad agent in real time with a a specified log
level
add endpoint tests
Upgrade go-hclog to latest version
The current version of go-hclog pads log prefixes to equal lengths
so info becomes [INFO ] and debug becomes [DEBUG]. This breaks
hashicorp/logutils/level.go Check function. Upgrading to the latest
version removes this padding and fixes log filtering that uses logutils
Check
Currently, nomad "plugin" processes (e.g. executor, logmon, docker_logger) are started as CLI
commands to be handled by command CLI framework. Plugin launchers use
`discover.NomadBinary()` to identify the binary and start it.
This has few downsides: The trivial one is that when running tests, one
must re-compile the nomad binary as the tests need to invoke the nomad
executable to start plugin. This is frequently overlooked, resulting in
puzzlement.
The more significant issue with `executor` in particular is in relation
to external driver:
* Plugin must identify the path of invoking nomad binary, which is not
trivial; `discvoer.NomadBinary()` now returns the path to the plugin
rather than to nomad, preventing external drivers from launching
executors.
* The external driver may get a different version of executor than it
expects (specially if we make a binary incompatible change in future).
This commit addresses both downside by having the plugin invocation
handling through an `init()` call, similar to how libcontainer init
handler is done in [1] and recommened by libcontainer [2]. `init()`
will be invoked and handled properly in tests and external drivers.
For external drivers, this change will cause external drivers to launch
the executor that's compiled against.
There a are a couple of downsides to this approach:
* These specific packages (i.e executor, logmon, and dockerlog) need to
be careful in use of `init()`, package initializers. Must avoid having
command execution rely on any other init in the package. I prefixed
files with `z_` (golang processes files in lexical order), but ensured
we don't depend on order.
* The command handling is spread in multiple packages making it a bit
less obvious how plugin starts are handled.

This command will be used to send a signal to either a single task within an
allocation, or all of the tasks if <task-name> is omitted. If the sent signal
terminates the allocation, it will be treated as if the allocation has crashed,
rather than as if it was operator-terminated.
Signal validation is currently handled by the driver itself and nomad
does not attempt to restrict or validate them.
