We have to set https_proxy & http_proxy for internet access from our cluster instances.
https_proxy & http_proxy environment variables should be exported to all pods so that application can access external sites.
We are using helm charts so is there common place we can set these environment variables so all pods can access internet.
you should be using PodPreset obejct to pass common environment variables and other params to all the matching pods.
The below PodPreset object would inject HTTPS_PROXY and HTTP_PROXY environment variable to all pods that match label 'setproxy:true'
apiVersion: settings.k8s.io/v1alpha1
kind: PodPreset
metadata:
name: inject-proxy-var
spec:
selector:
matchLabels:
setproxy: true
env:
- name: HTTPS_PROXY
value: "https_proxy"
- name: HTTP_PROXY
value: "http_proxy"Follow the link for more help --> https://kubernetes.io/docs/tasks/inject-data-application/podpreset/

If i understood it correctly, you want to set env variable to container. If this is correct understanding, You can use below configuration for container to set env variables
env:
- name: HTTPS_PROXY
value: "Value"
- name: HTTP_PROXY
value: "Value"You can check more details at :https://kubernetes.io/docs/tasks/inject-data-application/define-environment-variable-container/#define-an-environment-variable-for-a-container
