Prepare a VM for demo application

It could be Amazon EC2 instance based on the image "Amazon Linux 2 AMI (HVM), SSD Volume Type - ami-0e8c04af2729ff1bb (64-bit x86)" Ssh to the VM.

Update packages, install git and download demo application

sudo yum update -y
sudo yum install -y git
git clone https://github.com/progmaticlab/skynet

If needed enable data SlackBot Application

export SLACK_CHANNEL=skynet
export SHADOWCAT_BOT_TOKEN="xoxb-******"

Slack Bot App is to be created in advance, the app is to be added into the Slack channel and granted requried permisions. Permissions required for the app: calls:read, calls:write, chat:write, files:write. For backward notifications by buttons it is needed to manually set Request URL for the app on Slack site: http://54.214.233.135:8080/slack/proxy/ It is because there is no way to do it dynamically.

For the first run you will be asked to provide your Amazon access key and secret key as the applicaion needs to control Amazon EKS. Your IAM account needs to have rights to control Amazon EKS.

# provide name of cluster and context
export CLUSTER_NAME='istio-demo-cluster'
export CONTEXT_NAME='istio-demo'
./skynet/deploy_eks_sandbox.sh

Run demo application

./skynet/demo_inside_eks_sandbox.sh
