The `nomad fmt -check` command incorrectly writes to file because we didn't
return before writing the file on a diff. Fix this bug and update the command
internals to differentiate between the write-to-file and write-to-stdout code
paths, which are activated by different combinations of options and flags.
The docstring for the `-list` and `-write` flags is also unclear and can be
easily misread to be the opposite of the actual behavior. Clarify this and fix
up the docs to match.
This changeset also refactors the tests quite a bit so as to make the test
outputs clear when something is incorrect.
The panic bug for upgrades with older servers that shipped in 1.4.0 was fixed in
1.4.1, which makes the versions described in the warning in the upgrade guide
misleading. Clarify the upgrade guide.
* artifact: protect against unbounded artifact decompression
Starting with 1.5.0, set defaut values for artifact decompression limits.
artifact.decompression_size_limit (default "100GB") - the maximum amount of
data that will be decompressed before triggering an error and cancelling
the operation
artifact.decompression_file_count_limit (default 4096) - the maximum number
of files that will be decompressed before triggering an error and
cancelling the operation.
* artifact: assert limits cannot be nil in validation
* docs: add dynamic node metadata api docs
Also update all paths in the client API docs to explicitly state the
`/v1/` prefix. We're inconsistent about that, but I think it's better to
display the full path than to only show the fragment. If we ever do a
`/v2/` whether or not we explicitly state `/v1/` in our docs won't be
our greatest concern.
* docs: add task-api docs
In #13374 we updated the commented-out `license_path` in the packaged example
configuration file to match the existing documentation. Although this config
value was commented-out, it was reported that changing the value was
confusing. Update the commented-out line to the previous value and update the
documented examples to match that. This matches most of the examples for
Consul/Vault licensing as well. I've double-checked the tutorials and it looks
like it'd been left on the previous value there, so no additional work to be
done.
* Demoable state
* Demo mirage color
* Label as a block with foreground and background colours
* Test mock updates
* Go test updated
* Documentation update for label support
Service jobs should have unique allocation Names, derived from the
Job.ID. System jobs do not have unique allocation Names because the index is
intended to indicated the instance out of a desired count size. Because system
jobs do not have an explicit count but the results are based on the targeted
nodes, the index is less informative and this was intentionally omitted from the
original design.
Update docs to make it clear that NOMAD_ALLOC_INDEX is always zero for
system/sysbatch jobs
Validate that `volume.per_alloc` is incompatible with system/sysbatch jobs.
System and sysbatch jobs always have a `NOMAD_ALLOC_INDEX` of 0. So
interpolation via `per_alloc` will not work as soon as there's more than one
allocation placed. Validate against this on job submission.
* largely a doc-ification of this commit message:
d47678074b
this doesn't spell out all the possible failure modes,
but should be a good starting point for folks.
* connect: add doc link to envoy bootstrap error
* add Unwrap() to RecoverableError
mainly for easier testing
Add `identity` jobspec block to expose workload identity tokens to tasks.

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.
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.
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
This changeset fixes a long-standing point of confusion in metrics emitted by
the eval broker. The eval broker has a queue of "blocked" evals that are waiting
for an in-flight ("unacked") eval of the same job to be completed. But this
"blocked" state is not the same as the `blocked` status that we write to raft
and expose in the Nomad API to end users. There's a second metric
`nomad.blocked_eval.total_blocked` that refers to evaluations in that
state. This has caused ongoing confusion in major customer incidents and even in
our own documentation! (Fixed in this PR.)
There's little functional change in this PR aside from the name of the metric
emitted, but there's a bit refactoring to clean up the names in `eval_broker.go`
so that there aren't name collisions and multiple names for the same
state. Changes included are:
* Everything that was previously called "pending" referred to entities that were
associated witht he "ready" metric. These are all now called "ready" to match
the metric.
* Everything named "blocked" in `eval_broker.go` is now named "pending", except
for a couple of comments that actually refer to blocked RPCs.
* Added a note to the upgrade guide docs for 1.5.0.
* Fixed the scheduling performance metrics docs because the description for
`nomad.broker.total_blocked` was actually the description for
`nomad.blocked_eval.total_blocked`.
