cli: `service info` command returns incorrect services in output #19542

Open jrasell opened 11 months ago

Nomad version

$ nomad version
Nomad v1.7.3-dev
BuildDate 2023-12-19T11:17:48Z
Revision b2f640346d7609057ab55a0037c23ad5f5edfb68

Issue

The service info command returns incorrect results when attempting to perform a simple service lookup within a particular namespace.

The list output correctly lists two services registered:

$ nomad service list
Service Name       Tags
grafana-server     []
prometheus-server  []

When I go to lookup the grafana-server service I get the following result:

$ nomad service info grafana-server
Job ID             Address               Tags  Node ID   Alloc ID
prometheus-server  192.168.108.13:24057  []    fc18ed18  04499ded

The API is returning the correct data, so this is a problem with the command.

$ nomad operator api /v1/service/grafana-server | jq
[
  {
    "Address": "192.168.108.13",
    "AllocID": "8fe15d39-cd9d-cbdb-ca31-d795b4f4ca78",
    "CreateIndex": 188,
    "Datacenter": "kent",
    "ID": "_nomad-task-8fe15d39-cd9d-cbdb-ca31-d795b4f4ca78-group-server-grafana-server-grafana",
    "JobID": "grafana-server",
    "ModifyIndex": 188,
    "Namespace": "default",
    "NodeID": "fc18ed18-d4ef-115c-17f5-43e4e48c37a8",
    "Port": 22138,
    "ServiceName": "grafana-server",
    "Tags": []
  }
]

It seems the bug was introduced within https://github.com/hashicorp/nomad/pull/18836

I can see this in 1.7.2 as well. The nomad templates are also quite messed up similar to https://github.com/hashicorp/nomad/issues/16616

jrasell commented 10 months ago

Hi @blmhemu; as far as this stated issue goes, it only affects the CLI and the linked issue is a separate, non-related bug.

blmhemu commented 10 months ago

I understand, but i could not repro #16616 on 1.6, only on 1.7.(2) (Let me know if I should raise another issue)

Also, I assumed templates use the data published by the API and if the API provides wrong info, may be the templates are rendedered with wrong info.

Seeing this with the 1.7.5 CLI too:

Still relevant^, had me wondering where did I go wrong. @jrasell are you working on this? otherwise I think I can pick this up?

msherman13 commented 6 months ago

+1 on this, it's a bad issue that seems to have been included in one of the recent releases. breaks our workflow...

dpogorzelski commented 4 months ago

Still present in 1.8.1, just ran into this
