properly wire up durable event count
move newline responsibility
moves newline creation from NDJson to the http handler, json stream only encodes and sends now
ignore snapshot restore if broker is disabled
enable dev mode to access event steam without acl
use mapping instead of switch
use pointers for config sizes, remove unused ttl, simplify closed conn logic
Fixes#9017
The ?resources=true query parameter includes resources in the object
stub listings. Specifically:
- For `/v1/nodes?resources=true` both the `NodeResources` and
`ReservedResources` field are included.
- For `/v1/allocations?resources=true` the `AllocatedResources` field is
included.
The ?task_states=false query parameter removes TaskStates from
/v1/allocations responses. (By default TaskStates are included.)
* Node Drain events and Node Events (#8980)
Deployment status updates

* consolidate down to node event + type
* fix UpdateDeploymentAllocHealth test invocations
* fix test
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.
When deregistering a service, consul also deregisters the associated
checks. The current state keeps track of all services and all checks
separately and deregisters them in sequence, which leads, whether during
syncs or shutdowns, to check deregistrations happening twice and failing
the second time (generating errors in logs)
This fix includes:
- a fix to the sync logic that just pulls the checks *after* the
services have been synced
- a fix to the shutdown mechanism that gets an updated list of checks
after deregistering the services, so that we get a cleaner check
deregistration process.
The key generated from this command is used for gossip encrpytion, which utilizes AES GCM encryption. Using a key size of 16-bytes enables AES-128 while a key size of 32 bytes enables AES-256.
The underlying memberlist library supports the larger key size, and is ultimatley preferable from a security standpoint. Consul also uses 32 bytes by default: 1a14b94441
Since CPU resources are usually a soft limit it is desirable to allow
setting it as low as possible to allow tasks to run only in "idle" time.
Setting it to 0 is still not allowed to avoid potential unintentional
side effects with allowing a zero value. While there may not be any side
effects this commit attempts to minimize risk by avoiding the issue.
This does *not* change the defaults.
