The ACL token decoding was not correctly handling time duration
syntax such as "1h" which forced people to use the nanosecond
representation via the HTTP API.
The change adds an unmarshal function which allows this syntax to
be used, along with other styles correctly.
Prior to 2409f72 the code compared the modification index of a job to itself. Afterwards, the code compared the creation index of the job to itself. In either case there should never be a case of re-parenting of allocs causing the evaluation to trivially always result in false, which leads to unreclaimable memory.
Prior to this change allocations and evaluations for batch jobs were never garbage collected until the batch job was explicitly stopped. The new `batch_eval_gc_threshold` server configuration controls how often they are collected. The default threshold is `24h`.
* docker: set force=true on remove image to handle images referenced by multiple tags
This PR changes our call of docker client RemoveImage() to RemoveImageExtended with
the Force=true option set. This fixes a bug where an image referenced by more than
one tag could never be garbage collected by Nomad. The Force option only applies to
stopped containers; it does not affect running workloads.
* docker: add note about image_delay and multiple tags
While you can use any string value for a variable Item's key name
using characters that are outside of the set [unicode.Letter,
unicode.Number,`_`] will require the `index` function for direct
access.
* Ensure infra_image gets proper label used for reconciliation
Currently infra containers are not cleaned up as part of the dangling container
cleanup routine. The reason is that Nomad checks if a container is a Nomad owned
container by verifying the existence of the: `com.hashicorp.nomad.alloc_id` label.
Ensure we set this label on the infra container as well.
* fix unit test
* changelog: add entry

When registering a job with a service and 'consul.allow_unauthenticated=false',
we scan the given Consul token for an acceptable policy or role with an
acceptable policy, but did not scan for an acceptable service identity (which
is backed by an acceptable virtual policy). This PR updates our consul token
validation to also accept a matching service identity when registering a service
into Consul.
Fixes#15902
The getting started Tutorial has a post-installation steps section that includes
installing CNI plugins. Many users will want to use `bridge` networking right
out of the gate, so adding these same post-install instructions to the main docs
will be a better Day 0 experience for them.
* client: run alloc pre-kill hooks on last pass despite no live tasks
This PR fixes a bug where alloc pre-kill hooks were not run in the
edge case where there are no live tasks remaining, but it is also
the final update to process for the (terminal) allocation. We need
to run cleanup hooks here, otherwise they will not run until the
allocation gets garbage collected (i.e. via Destroy()), possibly
at a distant time in the future.
Fixes#15477
* client: do not run ar cleanup hooks if client is shutting down
When the template hook Update() method is called it may recreate the
template manager if the Nomad or Vault token has been updated.
This caused the new template manager did not have a driver handler
because this was only being set on the Poststart hook, which is not
called for inplace updates.
Also tightens up authentication for these endpoints by enforcing the server
certificate name is valid. We protect these endpoints currently by mTLS and
can't use an auth token because these endpoints are (uniquely) called by the
leader and followers for a given node won't have the leader's ephemeral ACL
token. Add a certificate name check that requests come from a server and not a
client, because no client should ever send these RPCs directly.
Scope the `footer` tag SCSS rule for the New Variable form to prevent it
from affecting other `<footer>` elements, such as the gutter menu Nomad
version section.
This PR adjusts the artifact sandbox on Linux to enable reading from known
system-wide git or mercurial configuration, if they exist.
Folks doing something odd like specifying custom paths for global config will
need to use the standard locations, or disable artifact filesystem isolation.
* nsd: block on removal of services
This PR uses a WaitGroup to ensure workload removals are complete
before returning from ServiceRegistrationHandler.RemoveWorkload of
the nomad service provider. The de-registration of individual services
still occurs asynchrously, but we must block on the parent removal
call so that we do not race with further operations on the same set
of services - e.g. in the case of a task restart where we de-register
and then re-register the services in quick succession.
Fixes#15032
* nsd: add e2e test for initial failing check and restart
Disallowing per_alloc for host volumes in some cases makes life of a nomad user much harder.
When we rely on the NOMAD_ALLOC_INDEX for any configuration that needs to be re-used across
restarts we need to make sure allocation placement is consistent. With CSI volumes we can
use the `per_alloc` feature but for some reason this is explicitly disabled for host volumes.
Ensure host volumes understand the concept of per_alloc
