Env variables in ~/.kube/config are skipped except AWS_PROFILE

[cscetbon]

Description:

Env variables grabbed from user.exec.env are not used

serverless-kubeless/lib/helpers.js

Lines 130 to 135 in 0b62c54

	if (env) {
	const profile = _.find(env, e => e.name === 'AWS_PROFILE');
	if (profile) {
	envvars.AWS_PROFILE = profile.value;
	}
	}

As you can see, only the AWS_PROFILE is used.

I expect those variables to be added to the env used by the aws cli command. In my case I'm trying to unset those variables by using

- name: eks_data
  user:
    exec:
      apiVersion: client.authentication.k8s.io/v1alpha1
      env:
      - name: AWS_ACCESS_KEY_ID
      - name: AWS_SECRET_ACCESS_KEY
      command: aws
      args:
      - eks
      - get-token
      - --cluster-name
      - data
      - --role
      - arn:aws:iam::my_role

The reason is that my aws creds to deploy using Serverless are different from the creds used to authenticate with my k8s cluster. But I need to interact with AWS to grab some variables from CF stacks' outputs.

I also found that

serverless-kubeless/lib/helpers.js

Line 129 in 0b62c54

const envvars = Object.assign({}, process.env);

is incorrect cause it's used at

serverless-kubeless/lib/helpers.js

Line 138 in 0b62c54

output = proc.execSync(cmd, envvars);

.
it should be replaced by

const envvars = Object.assign({}, {env: process.env});

Cause it's what expects https://nodejs.org/api/child_process.html#child_process_child_process_execsync_command_options
Or instead variables could be added to process.env and envvars is useless
How to reproduce it (as minimally and precisely as possible):
Have a similar configuration file

- name: eks_data
  user:
    exec:
      apiVersion: client.authentication.k8s.io/v1alpha1
      env:
      - name: AWS_ACCESS_KEY_ID
         value: your_access_key_id
      - name: AWS_SECRET_ACCESS_KEY
         value: your_secret_access_key
      command: aws
      args:
      - eks
      - get-token
      - --cluster-name
      - data
      - --role
      - arn:aws:iam::your_role

Set dummy variables in your env and run an sls deploy. Your dummy variables should be overwritten by those found in your ~/.kube/config and your deployment work.
