Configuring kubernetes on AWS

Microservices have become a popular architectural style for building cloud-native applications that are self-contained, independently deployable, resilient and quickly evolve.

Additionally, Istio makes it easy to create a network of deployed services with load balancing, service-to-service authentication, monitoring.

Therefore, you may use this sample code as a starting point for your development environment.

Best Approaches to have a K8S Cluster

Select one of the approach to start with;

• EKSCTL
• Kops
• Kubeadm
• Kubespray
• Kubernetes - the hard way

```shell script
export TF_VAR_AWS_ACCESS_KEY=”accesskey”
export TF_VAR_AWS_SECRET_KEY=”secretkey”
export TF_VAR_AWS_REGION=”eu-west-2”
export TF_VAR_trusted_ip_range=”$(curl http://ifconfig.co)/32“ # Or give your trusted IP range
export TF_VAR_PATH_TO_PUBLIC_KEY=”$HOME/.ssh/automation.pub”
export TF_VAR_PATH_TO_PRIVATE_KEY=”$HOME/.ssh/automation”
… and so on… ( Check vars.tf )
…export ansible vars…

* In order to ssh to nodes, you may use ssh-config as below;
```shell script
# Change bastion public ip in the config
$ ssh master-1 -F ./config

Test

• TODO: MoP will be prepared and many more will be added with automated tests…
  ```shell script
  $ terraform validate
  $ terraform fmt -check -diff
  $ chronic test.sh
  $ ansible-playbook -i inventory/inventory.static test.yaml
  $ ansible-playbook -i inventory/inventory.static test.yaml
  $ python ./inventory/ec2.py —list
  $ ansible -m ping “eu-west-2” -i inventory/ec2.py

```

Todos

• Write MORE Tests
• Deploy istio
• Creating a sample service mash.
