Updated configMap.yaml but it's not being applied to Kubernetes pods

I'm editing configMap.yaml in my Helm chart, but when I log in to one of my pods to check if it's being applied, it doesn't reflect my changes. I'm fairly new to Helm charts so any help is appreciated.

    After you edited cm, should restart you pod to reload new value.

    1. edit yaml file.
    2. kubectl apply -f cm.yaml
    3. kubectl delete po your-pod -n your-ns if controlled by a controller. If just pod, kubectl delete -f pod.yaml then kubectl create -f pod.yaml.

    For updating your ConfigMap you can also use kubectl patch command if you find it more fitting for you. Documentation regarding it can be found here.

    For applying the changes there is a very useful tool called Reloader. Reloader can watch changes in ConfigMap and Secret and do rolling upgrades on Pods with their associated DeploymentConfigs, Deployments, Daemonsets and Statefulsets.

    Please let me know if that helped.
