This PR introduces the /v1/search/fuzzy API endpoint, used for fuzzy
searching objects in Nomad. The fuzzy search endpoint routes requests
to the Nomad Server leader, which implements the Search.FuzzySearch RPC
method.
Requests to the fuzzy search API are based on the api.FuzzySearchRequest
object, e.g.
{
"Text": "ed",
"Context": "all"
}
Responses from the fuzzy search API are based on the api.FuzzySearchResponse
object, e.g.
{
"Index": 27,
"KnownLeader": true,
"LastContact": 0,
"Matches": {
"tasks": [
{
"ID": "redis",
"Scope": [
"default",
"example",
"cache"
]
}
],
"evals": [],
"deployment": [],
"volumes": [],
"scaling_policy": [],
"images": [
{
"ID": "redis:3.2",
"Scope": [
"default",
"example",
"cache",
"redis"
]
}
]
},
"Truncations": {
"volumes": false,
"scaling_policy": false,
"evals": false,
"deployment": false
}
}
The API is tunable using the new server.search stanza, e.g.
server {
search {
fuzzy_enabled = true
limit_query = 200
limit_results = 1000
min_term_length = 5
}
}
These values can be increased or decreased, so as to provide more
search results or to reduce load on the Nomad Server. The fuzzy search
API can be disabled entirely by setting `fuzzy_enabled` to `false`.
This PR adds a set of tests to the Consul test suite for testing
Nomad OSS's behavior around setting Consul Namespace on groups,
which is to ignore the setting (as Consul Namespaces are currently
an Enterprise feature).
Tests are generally a reduced facsimile of existing tests, modified
to check behavior of when group.consul.namespace is set and not set.
Verification is oriented around what happens in Consul; the in-depth
functional correctness of these features is left to the original tests.
Nomad ENT will get its own version of these tests in `namespaces_ent.go`.
This reverts commit 12bb509242109770c8318ec8ca61e54f4fa2bd42.
This change is causing compatibility issues with Consul 1.9.X;
I suspect the change is only compatible with Consul 1.10 or higher
which is not released yet, and not something Nomad can require
for quite some time.
E.g. when registering an ingress gateway,
```
consul.sync: failed to update services in Consul: error="Unexpected response code: 400 (Request decode failed: json: unknown field "TransparentProxy")"
```
on Linux systems this is derived from the configure cpuset cgroup parent (defaults to /nomad)
for non Linux systems and Linux systems where cgroups are not enabled, the client defaults to using all cores
This followup to #10066 adds a step to clear the one-time token
from the URL after the application has loaded. The delay is
required for it to actually clear, but only when the OTT is present
to avoid slowing down the entire test suite.
