k3s - Read-only file system

[Schwitzd]

Hello,

I would like to run mktxp-exporter in k3s, I created the secret with the command:

kubectl create secret generic mktxp-credentials --from-file mktxp-secrets.yaml -n monitoring

and then create the deployment on the same namespace. The pod is failing to start with this error:

Traceback (most recent call last):
  File "/usr/local/bin/mktxp", line 8, in <module>
    sys.exit(main())
             ^^^^^^

Many thx Schwitzd

it's what it says, an attempt to write into a read-only file. There's a tip on that in the doc, basically for this kind of environments just have the configs to contain all the latest setting.
