AWS_Kubernetes Examples: Some suggested improvements in the docs and scripts

[jblakley]

I ran into several issues while getting the AWS_Kubernetes example to run. Not done yet but here are some so far. Mostly documentation and account specific stuff.

1. the example wants to run in a directory ~/capture but that directory doesn't seem to get created by default. Perhaps I missed it. I fixed this with:
   ln -s ~/git/scanner/examples/apps/aws_kubernetes ~/capture

2. By default, I had my aws output format set to text. The scripts expect it to be set to json.
   aws configure --output json

3. Aside from altering the <BUCKET_NAME> in scanner-config.yaml.template, I also had to change the region and endpoint to us-east-1. I also changed the clustername but not sure I should have or needed to.

4. The trickiest -- I had to create an EKS IAM role called eksServiceRole through the AWS console and add the EKS Permissions that it suggested. There's certainly a way to do this through CLI but I didn't try that.

5. Related to Add stencils/windows to evaluator interface #4. The create_eks_cluster.sh script has an account number hardcoded into the ROLE_ARN string definition. I had to edit to change to my account. Would be better if this were a command line parameter.

6. It would be nice if the create_eks_cluster.sh would give a short status message while waiting . E.g., echo Cluster Status is $COND.

7. helm wasn't installed by default --> pip install helm

Still working through an issue around NodeInstanceRole. Will add to this thread as I get further.

More progress.

8. Need to change in create_eks_cluster.sh. Need to find the right AMI for the region.
   ParameterKey=NodeImageId,ParameterValue=ami-dea4d5a1 \# us-east-1 ami name -- change if not in us-west-2 as the default
ParameterKey=KeyName,ParameterValue=<YOUR_SSH_KEY_NAME> \ # SSH Key Name

9. I'm getting a helm error. However, I think things might still be working OK.
