Add docker runtime arguments to helm chart

Question

I have a docker image that I run with specific runtime arguments. When I install a helm chart to deploy the kubernetes pod with this image, the output from the pod is different from when I use 'docker run.' I found that I should use command and args parameters in the values.yml file and the templates/deployment directory but I'm still not getting the desired output.

I've tried different variations from these links but no luck: How to pass docker run flags via kubernetes pod How to pass dynamic arguments to a helm chart that runs a job How to pass arguments to Docker container in Kubernetes or OpenShift through command line?

Here's the docker run command: docker run --it --rm --network=host --ulimit rtptrio=0 --cap-add=sys_nice --ipc=private --sysctl fs.msqueue.msg_max="10000" image_name:tag

Which chart you want to deploy? What helm version are you using? How looks your helm command, which parameter did you use in command and which changes you made in templates/deployment and valuses.yaml? — PjoterS

Please try something like that:

apiVersion: v1
kind: Pod
metadata:
  name: example
spec:
  hostNetwork: true
  securityContext:
    capabilities:
      add: ["SYS_NICE"]
  containers:
  - name: main
    image: image_name:tag
