Previous and next is not working under logs

[johnr84]

Installation method: Kubernetes version: 1.21.1 Dashboard version: 2.3.1 Operating system: Ubuntu 20.04.2

Steps to reproduce Deploy Deployment with colored logs:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: color
spec:
  selector:
    matchLabels:
      app: color
  template:
    metadata:
      labels:
        app: color
    spec:
      containers:
      - image: ubuntu
        name: color
        command: ["/bin/bash", "-c", 'while true; do echo -e "Meet the \e[92mcucumber!"; sleep 1; done']

Go to pod logs. Click "<" or ">" button. It will show error as "The selected container has not logged any messages yet".

Observed result

Expected result Both the next and previous buttons shows the respective logs

I have tested it using provided deployment yaml and haven't encountered this issue. Are you sure you didn't check Show previous logs option?

[johnr84]

@floreks

No I didn't choose the "Show previous logs" option. I just tested the same on a kind cluster on my MAC and there it works as expected(In chrome). I am facing this problem in chrome browser on windows, I am not sure what is the reason. As mentioned, it works fine in the old dashboard version - 2.0.1 on our k8s 1.18.3 cluster.

Are there any unusual logs in the dev console? Can you also check API calls?

[dano0b]

dev console is empty, no errors or warnings.

Every second click is creating a different query:

:method: GET
:path: /api/v1/log/default/color-55bdd5665b-jpjmb/color?logFilePosition=&referenceTimestamp=2021-07-02T13:24:08.961448936+02:00&referenceLineNum=-1&offsetFrom=2500&offsetTo=2600&previous=false

:method: GET
:path: /api/v1/log/default/color-55bdd5665b-jpjmb/color?logFilePosition=&referenceTimestamp=&referenceLineNum=0&offsetFrom=0&offsetTo=100&previous=false

[floreks]

And the response of this call is what you see in the log viewer?

[dano0b]

every second is more or less empty:

{
 "info": {
  "podName": "color-55bdd5665b-jpjmb",
  "containerName": "color",
  "initContainerName": "",
  "fromDate": "",
  "toDate": "",
  "truncated": false
 },
 "selection": {
  "referencePoint": {
   "timestamp": "",
   "lineNum": 0
  },
  "offsetFrom": 0,
  "offsetTo": 0,
  "logFilePosition": ""
 },
 "logs": []
}

the healthy one:

{
 "info": {
  "podName": "color-55bdd5665b-jpjmb",
  "containerName": "color",
  "initContainerName": "",
  "fromDate": "2021-07-02T14:46:37.200487993+02:00",
  "toDate": "2021-07-02T14:48:16.360482711+02:00",
  "truncated": false
 },
 "selection": {
  "referencePoint": {
   "timestamp": "2021-07-02T14:06:33.223579256+02:00",
   "lineNum": -1
  },
  "offsetFrom": 2400,
  "offsetTo": 2500,
  "logFilePosition": ""
 },
 "logs": [
  {
   "timestamp": "2021-07-02T14:46:37.200487993+02:00",
   "content": "Meet the \u001b[92mcucumber!"
  },
...
}

Interesting. The parameters are missing. We have to find a way to reproduce this.
