Reduce log level for Docker (Kubernetes)

Hello everyone,

I need your help because I haven’t found the modification to make on my side.
We have installed Powershell Universal in Docker mode on a Kubernetes platform and we have a problem with the log level.
It’s in information. I’d like to set it to error but I haven’t found the option.

I’ve tried a few things in the settings.ps1 file.

LogLevel = “Error”
MicrosoftLogLevel = “Warning”
NotificationLevel = “Error”

Can you help me?

Thanks in advance

Product: PowerShell Universal
Version: 4.2.7

My understanding is that Kubernetes uses Podman not Docker. Can you confrim this is Docker or is it Podman.

Also, do you have a deployment script with environment variables. I suspect some code will need to be put in there to turn the logging level off.

Yes, you’re right, it is Pod.
I mentioned Docker because it’s the Powershell Universal image that’s used.


I set the following environment variable:

name = "SystemLogLevel
value = “Error”

The information is indeed present in /home/Universal/appsettings.linux.json

root@powershell-universal-5585456fdb-ftl2f:/home# cat Universal/appsettings.linux.json 
  "Kestrel": {
    "Endpoints": {
      "HTTP": {
        "Url": "http://*:5000"
    "RedirectToHttps": "false",
    "Hsts": {
      "MaxAgeDays": 365
  "Plugins": [
  "AllowedHosts": "*",
  "SystemLogPath": "%HOME%/PowerShellUniversal/systemLog.txt",
  "SystemLogLevel": "Information",

These environment varaibles should do the trick in your yml file:

      - SystemLogPath="%HOME%/PowerShellUniversal/systemLog.txt"
      - SystemLogLevel=Information


I added the following command to the dockerfile

# Replace SystemLogLevel in appsettings.linux.json
RUN sed -i 's/"SystemLogLevel": "Information"/"SystemLogLevel": "Error"/' /home/Universal/appsettings.linux.json
