Manage PKS on AWS

Automate Load balancer configuration & PKS cluster access on AWS.

Demo

What these scripts are not meant for (YET) !

  • Automate PKS deployment on AWS
  • Configure AWS cli

Before you begin

Assumption: Infrastructure paving was done using terraforming-pks.

PKS tile plan configuration

If you want to use Pod Security Policy with your PKS clusters, Enable PodSecuritypolicy Admission plugin in your PKS plan. Not a hard requirement for manage-pks scripts

Pod security policy is required, if using /utils/istio script in this project to install Istio.

Instructions

  1. Start by configuring PKS API access, please find detailed docs here.
pks login -a PKS-API --client-name CLIENT-NAME --client-secret CLIENT-SECRET -k
  1. Configure AWS cli to use your account
$ aws configure
AWS Access Key ID [None]: **************
AWS Secret Access Key [None]: ***************
Default region name [None]: ap-southeast1 (same as opsmanager region)
Default output format [None]:
  1. Configure
export ENV_NAME=my-env (Same as terraforming-pks terraform.tfvars)

export ROUTE_53_ZONE_ID=id (Zone Id which was used for PKS API)
  1. Start by provisioning a new cluster, this step will invoke command to create new cluster .
./manage-cluster provision

and follow instructions. This step will:

  • Fetch the domain address from Route53 HostedZone
  • Create a cluster with hostname as cluster_name-k8s.your_domain

  1. It will take some time to provision cluster, check status with pks cluster cluster-name before proceeding to next step.

  2. Once cluster provision status is succeeded, enable access using

./manage-cluster access

and follow instructions. This step will:

  • Fetch the master instances Ids
  • Configure Security Group
  • Create load-balancer
  • Add master nodes to load-balancer
  • Configure the A record in hosted zone
  • Get credentials using PKS cli & set kubectl context
  1. If you want to clean up AWS resources, Load balancer, security-group, A record in Hosted Zone
./manage-cluster cleanup

Above cleanup doesn't deletes the cluster itself, use pks delete-cluster cluster_name.
