Alloc exec only works when task is passed as a flag and not an arg.
Alloc logs currently accepts either, but alloc signal and restart only
accept task as an arg. This adds -task as a flag to the other alloc
commands to make the cli UX consistent. If task is passed as a flag and
an arg, it ignores the arg.
This PR makes it so the Consul sync logic will ignore operations that
do not specify an action to take (i.e. [de-]register [services|checks]).
Ideally such noops would be discarded at the callsites (i.e. users
of [Create|Update|Remove]Workload], but we can also be defensive
at the commit point.
Also adds 2 trace logging statements which are helpful for diagnosing
sync operations with Consul - when they happen and why.
Fixes#10797
When the `-verbose` flag is passed to the `nomad volume status` command, we
hit a code path where the rows of text to be formatted were not initialized
correctly, resulting in a panic in the CLI.
This PR fixes a bug where modifying the upstreams of a Connect sidecar proxy
would not result Consul applying the changes, unless an additional change to
the job would trigger a task replacement (thus replacing the service definition).
The fix is to check if upstreams have been modified between Nomad's view of the
sidecar service definition, and the service definition for the sidecar that is
actually registered in Consul.
Fixes#8754
This PR fixes some job submission plumbing to make sure the Consul Check parameters
- failure_before_critical
- success_before_passing
work with group-level services. They already work with task-level services.
System and batch jobs don't create deployments, which means nomad tries
to monitor a non-existent deployment when it runs a job and outputs an
error message. This adds a check to make sure a deployment exists before
monitoring. Also fixes some formatting.

Glint pulled in an updated version of mitchellh/go-testing-interface
which broke some existing tests because the update added a Parallel()
method to testing.T. This switches to the standard library testing.TB
which doesn't have a Parallel() method.
Adding '-verbose' will print out the allocation information for the
deployment. This also changes the job run command so that it now blocks
until deployment is complete and adds timestamps to the output so that
it's more in line with the output of node drain.
This uses glint to print in place in running in a tty. Because glint
doesn't yet support cmd/powershell, Windows workflows use a different
library to print in place, which results in slightly different
formatting: 1) different margins, and 2) no spinner indicating
deployment in progress.

This PR moves a lot of Consul ACL token validation tests into ent files,
so that we can verify correct behavior difference between OSS and ENT
Nomad versions.
This PR fixes the Nomad Object Namespace <-> Consul ACL Token relationship
check when using Consul OSS (or Consul ENT without namespace support).
Nomad v1.1.0 introduced a regression where Nomad would fail the validation
when submitting Connect jobs and allow_unauthenticated set to true, with
Consul OSS - because it would do the namespace check against the Consul ACL
token assuming the "default" namespace, which does not work because Consul OSS
does not have namespaces.
Instead of making the bad assumption, expand the namespace check to handle
each special case explicitly.
Fixes#10718
This PR changes Nomad's wrapper around the Consul NamespaceAPI so that
it will detect if the Consul Namespaces feature is enabled before making
a request to the Namespaces API. Namespaces are not enabled in Consul OSS,
and require a suitable license to be used with Consul ENT.
Previously Nomad would check for a 404 status code when makeing a request
to the Namespaces API to "detect" if Consul OSS was being used. This does
not work for Consul ENT with Namespaces disabled, which returns a 500.
Now we avoid requesting the namespace API altogether if Consul is detected
to be the OSS sku, or if the Namespaces feature is not licensed. Since
Consul can be upgraded from OSS to ENT, or a new license applied, we cache
the value for 1 minute, refreshing on demand if expired.
Fixes https://github.com/hashicorp/nomad-enterprise/issues/575
Note that the ticket originally describes using attributes from https://github.com/hashicorp/nomad/issues/10688.
This turns out not to be possible due to a chicken-egg situation between
bootstrapping the agent and setting up the consul client. Also fun: the
Consul fingerprinter creates its own Consul client, because there is no
[currently] no way to pass the agent's client through the fingerprint factory.
This PR implements first-class support for Nomad running Consul
Connect Mesh Gateways. Mesh gateways enable services in the Connect
mesh to make cross-DC connections via gateways, where each datacenter
may not have full node interconnectivity.
Consul docs with more information:
https://www.consul.io/docs/connect/gateways/mesh-gateway
The following group level service block can be used to establish
a Connect mesh gateway.
service {
connect {
gateway {
mesh {
// no configuration
}
}
}
}
Services can make use of a mesh gateway by configuring so in their
upstream blocks, e.g.
service {
connect {
sidecar_service {
proxy {
upstreams {
destination_name = "<service>"
local_bind_port = <port>
datacenter = "<datacenter>"
mesh_gateway {
mode = "<mode>"
}
}
}
}
}
}
Typical use of a mesh gateway is to create a bridge between datacenters.
A mesh gateway should then be configured with a service port that is
mapped from a host_network configured on a WAN interface in Nomad agent
config, e.g.
client {
host_network "public" {
interface = "eth1"
}
}
Create a port mapping in the group.network block for use by the mesh
gateway service from the public host_network, e.g.
network {
mode = "bridge"
port "mesh_wan" {
host_network = "public"
}
}
Use this port label for the service.port of the mesh gateway, e.g.
service {
name = "mesh-gateway"
port = "mesh_wan"
connect {
gateway {
mesh {}
}
}
}
Currently Envoy is the only supported gateway implementation in Consul.
By default Nomad client will run the latest official Envoy docker image
supported by the local Consul agent. The Envoy task can be customized
by setting `meta.connect.gateway_image` in agent config or by setting
the `connect.sidecar_task` block.
Gateways require Consul 1.8.0+, enforced by the Nomad scheduler.
Closes#9446
In this loop, we ought to close the websocket connection gracefully when
the StreamErrWrapper reaches EOF.
Previously, it's possible that that we drop the last few events or skip sending
the websocket closure. If `handler(handlerPipe)` returns and `cancel` is called,
before the loop here completes processing streaming events, the loop exits
prematurely without propagating the last few events.
Instead here, the loop continues until we hit `httpPipe` EOF (through
`decoder.Decode`), to ensure we process the events to completion.
When a wildcard namespace is used for `nomad job` commands that support prefix
matching, avoid asking the user for input if a prefix is an unambiguous exact
match so that the behavior is similar to the commands using a specific or
unset namespace.
The websocket interface used for `alloc exec` has to silently drop client send
errors because otherwise those errors would interleave with the streamed
output. But we may be able to surface errors that cause terminated websockets
a little better in the HTTP server logs.
The `Terminates At` field can't be removed from the struct for backwards
compatibility reasons, but there's no purpose to it anymore so we shouldn't be
showing it to end users of the command.
This PR adds e2e tests for Consul Namespaces for Nomad Enterprise
with Consul ACLs enabled.
Needed to add support for Consul ACL tokens with `namespace` and
`namespace_prefix` blocks, which Nomad parses and validates before
tossing the token. These bits will need to be picked back to OSS.
ParentID is an internal field that Nomad sets for dispatched or parameterized jobs. Job submitters should not be able to set it directly, as that messes up children tracking.
Fixes#10422 . It specifically stops the scheduler from honoring the ParentID. The reason failure and why the scheduler didn't schedule that job once it was created is very interesting and requires follow up with a more technical issue.

- Group level script checks were not getting Namespace set
Those changes will need to be copied back to Nomad OSS.

This PR introduces the /v1/search/fuzzy API endpoint, used for fuzzy
searching objects in Nomad. The fuzzy search endpoint routes requests
to the Nomad Server leader, which implements the Search.FuzzySearch RPC
method.
Requests to the fuzzy search API are based on the api.FuzzySearchRequest
object, e.g.
{
"Text": "ed",
"Context": "all"
}
Responses from the fuzzy search API are based on the api.FuzzySearchResponse
object, e.g.
{
"Index": 27,
"KnownLeader": true,
"LastContact": 0,
"Matches": {
"tasks": [
{
"ID": "redis",
"Scope": [
"default",
"example",
"cache"
]
}
],
"evals": [],
"deployment": [],
"volumes": [],
"scaling_policy": [],
"images": [
{
"ID": "redis:3.2",
"Scope": [
"default",
"example",
"cache",
"redis"
]
}
]
},
"Truncations": {
"volumes": false,
"scaling_policy": false,
"evals": false,
"deployment": false
}
}
The API is tunable using the new server.search stanza, e.g.
server {
search {
fuzzy_enabled = true
limit_query = 200
limit_results = 1000
min_term_length = 5
}
}
These values can be increased or decreased, so as to provide more
search results or to reduce load on the Nomad Server. The fuzzy search
API can be disabled entirely by setting `fuzzy_enabled` to `false`.
on Linux systems this is derived from the configure cpuset cgroup parent (defaults to /nomad)
for non Linux systems and Linux systems where cgroups are not enabled, the client defaults to using all cores
Consul allows specifying the HTTP body to send in a health check. Nomad
uses Consul for health checking so this just plumbs the value through to
where the Consul API is called.
There is no validation that `body` is not used with an incompatible
check method like GET.
The AWS EBS CSI plugin was observed to return a EOF when we get to the end of
the paging for `ListSnapshots`, counter to specification. Handle this case
gracefully, including for `ListVolumes` (which EBS doesn't support but has
similar semantics).
Also fixes a timestamp formatting bug on `ListSnapshots`
Our API client `delete` method doesn't include a request body, but accepts an
interface for the response. We were accidentally putting the request body into
the response, which doesn't get picked up in unit tests because we're not
reading the (always empty) response body anyways.
The HTTP router did not correctly route `/v1/volumes/external` without being
explicitly added to the top-level router. Break this out into its own request
handler.
If a plugin returns an error, we should continue at the outer scope to query
the next plugin, otherwise we just retry the plugin we got an error
on (potentially infinitely if it's an invalid request like an unsupported
plugin).
Add new `access_mode`/`attachment_mode` fields. Make it more clear which set
of fields belong to create vs register. Update the example spec that's
generated by `volume init`.
Registration of Nomad volumes previously allowed for a single volume
capability (access mode + attachment mode pair). The recent `volume create`
command requires that we pass a list of requested capabilities, but the
existing workflow for claiming volumes and attaching them on the client
assumed that the volume's single capability was correct and unchanging.
Add `AccessMode` and `AttachmentMode` to `CSIVolumeClaim`, use these fields to
set the initial claim value, and add backwards compatibility logic to handle
the existing volumes that already have claims without these fields.
This PR adds the common OSS changes for adding support for Consul Namespaces,
which is going to be a Nomad Enterprise feature. There is no new functionality
provided by this changeset and hopefully no new bugs.
When a volume is registered via `nomad volume register` and not via the
creation workflow, it may not have any of the capacity fields set (as they're
not used for registration). Handle this case without error, and let the
downstream RPCs handle the error case for `nomad volume create`.
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.
The HTTP test to create CSI volumes depends on having a controller plugin to
talk to, but the test was using a node-only plugin, which allows it to
silently ignore the missing controller.
This commit includes a new test client that allows overriding the RPC
protocols. Only the RPCs that are passed in are registered, which lets you
implement a mock RPC in the server tests. This commit includes an example of
this for the ClientCSI RPC server.
This commit updates the API to pass the MemoryMaxMB field, and the CLI to show
the max set for the task.
Also, start parsing the MemoryMaxMB in hcl2, as it's set by tags.

Add a `PerAlloc` field to volume requests that directs the scheduler to test
feasibility for volumes with a source ID that includes the allocation index
suffix (ex. `[0]`), rather than the exact source ID.
Read the `PerAlloc` field when making the volume claim at the client to
determine if the allocation index suffix (ex. `[0]`) should be added to the
volume source ID.
Callers of `CSIVolumeByID` are generally assuming they should receive a single
volume. This potentially results in feasibility checking being performed
against the wrong volume if a volume's ID is a prefix substring of other
volume (for example: "test" and "testing").
Removing the incorrect prefix matching from `CSIVolumeByID` breaks prefix
matching in the command line client. Add the required elements for prefix
matching to the commands and API.
Create a convenience command for generating example CSI volume specifications,
similar to the existing `nomad job init` or `nomad quota init` commands.

Volume IDs are not UUIDs, so truncating them to the short ID isn't really
necessary and makes for especially awkward UX when per-alloc volumes are in
use.
If the user has disabled Prometheus metrics and a request is
sent to the metrics endpoint requesting Prometheus formatted
metrics, then the request should fail.
This PR fixes a bug where sidecar services would be re-registered into Consul every ~30
seconds, caused by the parent service having its tags field set and the sidecar_service
tags unset. Nomad would directly compare the tags between its copy of the sidecar service
definition and the tags of the sidecar service reported by Consul. This does not work,
because Consul will under-the-hood set the sidecar service tags to inherit the parent
service tags if the sidecar service tags are unset. The comparison then done by Nomad
would not match, if the parent sidecar tags are set.
Fixes#10025
Allow for readiness type checks by configuring nomad to ignore warnings
or errors reported by a service check. This allows the deployment to
progress and while Consul handles introducing the sercive into a
resource pool once the check passes.
This PR adds default_pid_mode and default_ipc_mode options to the exec and java
task drivers. By default these will default to "private" mode, enabling PID and
IPC isolation for tasks. Setting them to "host" mode disables isolation. Doing
so is not recommended, but may be necessary to support legacy job configurations.
Closes#9969
This PR implements Nomad built-in support for running Consul Connect
terminating gateways. Such a gateway can be used by services running
inside the service mesh to access "legacy" services running outside
the service mesh while still making use of Consul's service identity
based networking and ACL policies.
https://www.consul.io/docs/connect/gateways/terminating-gateway
These gateways are declared as part of a task group level service
definition within the connect stanza.
service {
connect {
gateway {
proxy {
// envoy proxy configuration
}
terminating {
// terminating-gateway configuration entry
}
}
}
}
Currently Envoy is the only supported gateway implementation in
Consul. The gateay task can be customized by configuring the
connect.sidecar_task block.
When the gateway.terminating field is set, Nomad will write/update
the Configuration Entry into Consul on job submission. Because CEs
are global in scope and there may be more than one Nomad cluster
communicating with Consul, there is an assumption that any terminating
gateway defined in Nomad for a particular service will be the same
among Nomad clusters.
Gateways require Consul 1.8.0+, checked by a node constraint.

* Prevent Job Statuses from being calculated twice
https://github.com/hashicorp/nomad/pull/8435 introduced atomic eval
insertion iwth job (de-)registration. This change removes a now obsolete
guard which checked if the index was equal to the job.CreateIndex, which
would empty the status. Now that the job regisration eval insetion is
atomic with the registration this check is no longer necessary to set
the job statuses correctly.

This removes modification of ops in methods that UpdateWorkload calls, keeping
them local to UpdateWorkload. It also includes some rewrites of checkRegs for
clarity.
Submitting a job with an ingress gateway in host networking mode
with an absent gateway.proxy block would cause the Nomad client
to panic on NPE.
The consul registration bits would assume the proxy stanza was
not nil, but it could be if the user does not supply any manually
configured envoy proxy settings.
Check the proxy field is not nil before using it.
Fixes#9669
https://github.com/hashicorp/nomad/pull/9608 introduced the use of the
built-in HTTP 429 response handler provided by go-connlimit. There is
concern though around plausible DOS attacks that need to be addressed,
so this PR reverts that functionality.
It keeps a fix in the tests around the use of an HTTPS enabled client
for when the server is listening on HTTPS. Previously, the tests would
fail deterministically with io.EOF because that's how the TLS server
terminates invalid connections.
Now, the result is much less deterministic. The state of the client
connection and the server socket depends on when the connection is
closed and how far along the handshake was.
In a few places Nomad was using flag implementations directly
from Consul, lending to Nomad's need to import consul. Replace
those uses with helpers already in Nomad, and copy over the bare
minimum needed to make the autopilot flags behave as they have.
This is essentially a port of Consul's similar fix

Before, upstreams could only be defined using the default datacenter.
Now, the `datacenter` field can be set in a connect upstream definition,

in the specified datacenter. The field is optional and continues to
default to the local datacenter.
Closes#8964
The API is missing values for `ReadAllocs` and `WriteAllocs` fields, resulting
in allocation claims not being populated in the web UI. These fields mirror
the fields in `nomad/structs.CSIVolume`. Returning a separate list of stubs
for read and write would be ideal, but this can't be done without either
bloating the API response with repeated full `Allocation` data, or causing a
panic in previous versions of the CLI.
The `nomad/structs` fields are persisted with nil values and are populated
during RPC, so we'll do the same in the HTTP API and populate the `ReadAllocs`
and `WriteAllocs` fields with a map of allocation IDs, but with null
values. The web UI will then create its `ReadAllocations` and
`WriteAllocations` fields by mapping from those IDs to the values in
`Allocations`, instead of flattening the map into a list.

The `nomad alloc logs` command does not remove terminal escape sequences for
color from the log outputs of a task. Clarify that the standard `-no-color`
flag, which does apply to Nomad's error responses from `nomad alloc logs`,
does not apply to the log output.
The `nomad alloc status -verbose` command returns a 404 from CSI volumes
because the volume mount block in the task points back to the
`job.group.volume` block. So using the `Name` field to query is the "name" as
seen in the jobspec, and not the name of the volume that we need for querying.
Show both the job-specific name and the volume ID in the resulting output,
which clarifies the difference between the two fields and is more consistent
with the web UI.
This PR adds the ability to set HTTP headers when downloading
an artifact from an `http` or `https` resource.
The implementation in `go-getter` is such that a new `HTTPGetter`
must be created for each artifact that sets headers (as opposed
to conveniently setting headers per-request). This PR maintains
the memoization of the default Getter objects, creating new ones
only for artifacts where headers are set.

Previously, connect sidecars would be re-registered with consul every cycle
of Nomad's reconciliation loop around Consul service registrations. This is
because part of the comparison used `reflect.DeepEqual` on []string objects,
which returns false when one object is `[]string{}` and the other is `[]string{}(nil)`.
Unforunately, this was always the case, and every Connect sidecar service
would be re-registered on every iteration, which happens every 30 seconds.
The unpublish workflow requires that we know the mode (RW vs RO) if we want to
unpublish the node. Update the hook and the Unpublish RPC so that we mark the
claim for release in a new state but leave the mode alone. This fixes a bug
where RO claims were failing node unpublish.
The core job GC doesn't know the mode, but we don't need it for that workflow,
so add a mode specifically for GC; the volumewatcher uses this as a sentinel
to check whether claims (with their specific RW vs RO modes) need to be claimed.
The only user of monitor(evalID, true) was command/eval_status, and
eval_status had a duplicate of the prefix-handling code inside it, so in
all cases the complete evalID was being passed to monitor.
Given that, we can remove the prefix code from command/monitor, and
remove the boolean arg.

This Commit adds an /v1/events/stream endpoint to stream events from.
The stream framer has been updated to include a SendFull method which
does not fragment the data between multiple frames. This essentially
treats the stream framer as a envelope to adhere to the stream framer
interface in the UI.
If the `encode` query parameter is omitted events will be streamed as
newline delimted JSON.
As newer versions of Consul are released, the minimum version of Envoy
it supports as a sidecar proxy also gets bumped. Starting with the upcoming
Consul v1.9.X series, Envoy v1.11.X will no longer be supported. Current
versions of Nomad hardcode a version of Envoy v1.11.2 to be used as the
default implementation of Connect sidecar proxy.
This PR introduces a change such that each Nomad Client will query its
local Consul for a list of Envoy proxies that it supports (https://github.com/hashicorp/consul/pull/8545)
and then launch the Connect sidecar proxy task using the latest supported version
of Envoy. If the `SupportedProxies` API component is not available from
Consul, Nomad will fallback to the old version of Envoy supported by old
versions of Consul.
Setting the meta configuration option `meta.connect.sidecar_image` or
setting the `connect.sidecar_task` stanza will take precedence as is
the current behavior for sidecar proxies.
Setting the meta configuration option `meta.connect.gateway_image`
will take precedence as is the current behavior for connect gateways.
`meta.connect.sidecar_image` and `meta.connect.gateway_image` may make
use of the special `${NOMAD_envoy_version}` variable interpolation, which
resolves to the newest version of Envoy supported by the Consul agent.
Addresses #8585#7665
When we try to prefix match the `nomad volume detach` node ID argument, the
node may have been already GC'd. The volume unpublish workflow gracefully
handles this case so that we can free the claim. So make a best effort to find
a node ID among the volume's claimed allocations, or otherwise just use the
node ID we've been given by the user as-is.
Fixes a bug where the `nomad volume detach` command would not accept a node ID
prefix instead of a full node ID. The volume ID is already prefix matched
server-side.
