This PR updates the version of redis used in our examples from 3.2 to 7.
The old version is very not supported anymore, and we should be setting
a good example by using a supported version.
The long-form example job is now fixed so that the service stanza uses
nomad as the service discovery provider, and so now the job runs without
a requirement of having Consul running and configured.
After a more detailed analysis of this feature, the approach taken in
PR #12449 was found to be not ideal due to poor UX (users are
responsible for setting the entity alias they would like to use) and
issues around jobs potentially masquerading itself as another Vault
entity.
This PR introduces the `address` field in the `service` block so that Nomad
or Consul services can be registered with a custom `.Address.` to advertise.
The address can be an IP address or domain name. If the `address` field is
set, the `service.address_mode` must be set in `auto` mode.

We expect every Nomad API client to use a single connection to any
given agent, so take advantage of keep-alive by switching the default
transport to `DefaultPooledClient`. Provide a facility to close idle
connections for testing purposes.
Restores the previously reverted #12409

The only difference is DefaultTransport sets DisableKeepAlives
This doesn't make much sense to me - every http connection from the
nomad client goes to the same NOMAD_ADDR so it's a great case for keep
alive. Except round robin DNS and anycast perhaps.
Consul does this already

Move some common Vault API data struct decoding out of the Vault client
so it can be reused in other situations.
Make Vault job validation its own function so it's easier to expand it.
Rename the `Job.VaultPolicies` method to just `Job.Vault` since it
returns the full Vault block, not just their policies.
Set `ChangeMode` on `Vault.Canonicalize`.
Add some missing tests.
Allows specifying an entity alias that will be used by Nomad when
deriving the task Vault token.
An entity alias assigns an indentity to a token, allowing better control
and management of Vault clients since all tokens with the same indentity
alias will now be considered the same client. This helps track Nomad
activity in Vault's audit logs and better control over Vault billing.
Add support for a new Nomad server configuration to define a default
entity alias to be used when deriving Vault tokens. This default value
will be used if the task doesn't have an entity alias defined.
Pass-through the `-secret` and `-parameter` flags to allow setting
parameters for the snapshot and overriding the secrets we've stored on
the CSI volume in the state store.
The service registration client name was used to provide a
distinction between the service block and the service client. This
however creates new wording to understand and does not match the
CLI, therefore this change fixes that so we have a Services
client.
Consul specific objects within the service file have been moved to
the consul location to create a clearer separation.
The `related` query param is used to indicate that the request should
return a list of related (next, previous, and blocked) evaluations.

This is a followup to running tests in serial in CI.
Since the API package cannot import anything outside of api/,
copy the ci.Parallel function into api/internal/testutil, and
have api tests use that.
When we set the headers for CSI secrets in the `WriteOptions`, it
turns out that we're not always passing a non-nil object. In that
case, instanstiate it on demand in the API.
The paginator logic was built when go-memdb iterators would return items
ordered lexicographically by their ID prefixes, but #12054 added the
option for some tables to return results ordered by their `CreateIndex`
instead, which invalidated the previous paginator assumption.
The iterator used for pagination must still return results in some order
so that the paginator can properly handle requests where the next_token
value is not present in the results anymore (e.g., the eval was GC'ed).
In these situations, the paginator will start the returned page in the
first element right after where the requested token should've been.
This commit moves the logic to generate pagination tokens from the
elements being paginated to the iterator itself so that callers can have
more control over the token format to make sure they are properly
ordered and stable.
It also allows configuring the paginator as being ordered in ascending
or descending order, which is relevant when looking for a token that may
not be present anymore.
Detection of the full set of plugin capabilities was added in Nomad
1.1 for the volume creation workflow, but these were not added to the
API response for plugins.
These API endpoints now return results in chronological order. They
can return results in reverse chronological order by setting the
query parameter ascending=true.
- Eval.List
- Deployment.List
This PR replaces use of time.After with a safe helper function
that creates a time.Timer to use instead. The new function returns
both a time.Timer and a Stop function that the caller must handle.
Unlike time.NewTimer, the helper function does not panic if the duration
set is <= 0.
This PR sets the minimum Go version for the `api` submodule to Go 1.17.
It also upgrades
- gorilla/websocket 1.4.1 -> 1.4.2
- mitchelh/mapstructure 1.4.2 -> 1.4.3
- stretchr/testify 1.5.1 -> 1.7.0
Closes#11518#11602#11528
After swapping gzip handler to use the gorilla library, we
must account for a quirk in how zero/minimal length response
bodies are delivered.
The previous gzip handler was configured to compress all responses
regardless of size - even if the data was zero length or below the
network MTU. This behavior changed in [v1.1.0](c551b6c3b4 (diff-de723e6602cc2f16f7a9d85fd89d69954edc12a49134dab8901b10ee06d1879d))
which is why we could not upgrade.
The Nomad HTTP Client mutates the http.Response.Body object, making
a strong assumption that if the Content-Encoding header is set to "gzip",
the response will be readable via gzip decoder. This is no longer true
for the nytimes gzip handler, and is also not true for the gorilla gzip
handler.
It seems in practice this only makes a difference on the /v1/operator/license
endpoint which returns an empty response in OSS Nomad.
The fix here is to simply not wrap the response body reader if we
encounter an io.EOF while creating the gzip reader - indicating there
is no data to decode.
