The existing docs on required capabilities are a little sparse and have been the
subject of a lots of questions. Expand on this information and provide a pointer
to the ongoing design discussion around rootless Nomad.
* client: ensure minimal cgroup controllers enabled
This PR fixes a bug where Nomad could not operate properly on operating
systems that set the root cgroup.subtree_control to a set of controllers that
do not include the minimal set of controllers needed by Nomad.
Nomad needs these controllers enabled to operate:
- cpuset
- cpu
- io
- memory
- pids
Now, Nomad will ensure these controllers are enabled during Client initialization,
adding them to cgroup.subtree_control as necessary. This should be particularly
helpful on the RHEL/CentOS/Fedora family of system. Ubuntu systems should be
unaffected as they enable all controllers by default.
Fixes: https://github.com/hashicorp/nomad/issues/14494
* docs: cleanup doc string
* client: cleanup controller writes, enhance log messages
The configuration knobs for root keyring garbage collection are present in the
consumer and present in the user-facing config, but we missed the spot where we
copy from one to the other. Fix this so that users can set their own thresholds.
The root key is automatically rotated every ~30d, but the function that does
both rotation and key GC was wired up such that `nomad system gc` caused an
unexpected key rotation. Split this into two functions so that `nomad system gc`
cleans up old keys without forcing a rotation, which will be done periodially
or by the `nomad operator root keyring rotate` command.
* keyring: don't unblock early if rate limit burst exceeded
The rate limiter returns an error and unblocks early if its burst limit is
exceeded (unless the burst limit is Inf). Ensure we're not unblocking early,
otherwise we'll only slow down the cases where we're already pausing to make
external RPC requests.
* keyring: set MinQueryIndex on stale queries
When keyring replication makes a stale query to non-leader peers to find a key
the leader doesn't have, we need to make sure the peer we're querying has had a
chance to catch up to the most current index for that key. Otherwise it's
possible for newly-added servers to query another newly-added server and get a
non-error nil response for that key ID.
Ensure that we're setting the correct reply index in the blocking query.
Note that the "not found" case does not return an error, just an empty key. So
as a belt-and-suspenders, update the handling of empty responses so that we
don't break the loop early if we hit a server that doesn't have the key.
* test for adding new servers to keyring
* leader: initialize keyring after we have consistent reads
Wait until we're sure the FSM is current before we try to initialize the
keyring.
Also, if a key is rotated immediately following a leader election, plans that
are in-flight may get signed before the new leader has the key. Allow for a
short timeout-and-retry to avoid rejecting plans
Originally this test relied on Job 1 blocking Job 2 until Job 1 had a
terminal *ClientStatus.* Job 2 ensured it would get blocked using 2
mechanisms:
1. A constraint requiring it is placed on the same node as Job 1.
2. Job 2 would require all unreserved CPU on the node to ensure it would
be blocked until Job 1's resources were free.
That 2nd assertion breaks if *any previous job is still running on the
target node!* That seems very likely to happen in the flaky world of our
e2e tests. In fact there may be some jobs we intentionally want running
throughout; in hindsight it was never safe to assume my test would be
the only thing scheduled when it ran.
*Ports to the rescue!* Reserving a static port means that both Job 2
will now block on Job 1 being terminal. It will only conflict with other
tests if those tests use that port *on every node.* I ensured no
existing tests were using the port I chose.
Other changes:
- Gave job a bit more breathing room resource-wise.
- Tightened timings a bit since previous failure ran into the `go test`
time limit.
- Cleaned up the DumpEvals output. It's quite nice and handy now!
ACL tokens are granted permissions either by direct policy links
or via ACL role links. Callers should therefore be able to read
policies directly assigned to the caller token or indirectly by
ACL role links.

This changes adds ACL role creation and deletion to the event
stream. It is exposed as a single topic with two types; the filter
is primarily the role ID but also includes the role name.
While conducting this work it was also discovered that the events
stream has its own ACL resolution logic. This did not account for
ACL tokens which included role links, or tokens with expiry times.
ACL role links are now resolved to their policies and tokens are
checked for expiry correctly.
The client ACL cache was not accounting for tokens which included
ACL role links. This change modifies the behaviour to resolve role
links to policies. It will also now store ACL roles within the
cache for quick lookup. The cache TTL is configurable in the same
manner as policies or tokens.
Another small fix is included that takes into account the ACL
token expiry time. This was not included, which meant tokens with
expiry could be used past the expiry time, until they were GC'd.
Rename `Internals` section to `Concepts` to match core docs structure
and expand on how policies are evaluated.
Also include missing documentation for check grouping and fix examples
to use the new feature.
* Adds searching and filtering for nodes on topology view
* Lintfix and changelog
* Acceptance tests for topology search and filter
* Search terms also apply to class and dc on topo page
* Initialize queryparam values so as to not break history state
Move the Autoscaler agent configuration `source` to the `policy` page
since they are very closely related.
Also update all headers in this section so they follow the proper `h1 >
h2 > h3 > ...` hierarchy.
* consul: register checks along with service on initial registration
This PR updates Nomad's Consul service client to include checks in
an initial service registration, so that the checks associated with
the service are registered "atomically" with the service. Before, we
would only register the checks after the service registration, which
causes problems where the service is deemed healthy, even if one or
more checks are unhealthy - especially problematic in the case where
SuccessBeforePassing is configured.
Fixes#3935
* cr: followup to fix cause of extra consul logging
* cr: fix another bug
* cr: fixup changelog
My make knowledge is very very limited, so if there's a better way to do
this please let me know! This seems to work and lets me cut one off
builds easily.
This PR updates Nomad's Consul service client to do map comparisons
using maps.Equal instead of reflect.DeepEqual. The bug fix is in how
DeepEqual treats nil slices different from empty slices, when actually
they should be treated the same.
* One-time tokens are not replicated between regions, so we don't want to enforce
that the version check across all of serf, just members in the same region.
* Scheduler: Disconnected clients handling is specific to a single region, so we
don't want to enforce that the version check across all of serf, just members in
the same region.
* Variables: enforce version check in Apply RPC
* Cleans up a bunch of legacy checks.
This changeset is specific to 1.4.x and the changes for previous versions of
Nomad will be manually backported in a separate PR.
In #14821 we fixed a panic that can happen if a leadership election happens in
the middle of an upgrade. That fix checks that all servers are at the minimum
version before initializing the keyring (which blocks evaluation processing
during trhe upgrade). But the check we implemented is over the serf membership,
which includes servers in any federated regions, which don't necessarily have
the same upgrade cycle.
Filter the version check by the leader's region.
Also bump up log levels of major keyring operations
