Create kops user

S3 Buckets

Kops needs dedicated S3 bucket to store artifacts.

We will create one for each environment now: DEV, UAT, PROD.

Naming convention: PROJECT-k8s-ENVIRONMENT

## List existing buckets
➜  etc git:(feature/kubernetes) aws s3api list-buckets
{
    "Buckets": [],
    "Owner": {
        "DisplayName": "twfulfillment.aws",
        "ID": "f4d3f1f61cb382de98ebf5b7d58306b66ad6108cdd1916cdd3cce94e88aeeb47"
    }
}
 
## For buckets not in us-east-1 we need location constraint
 
➜  etc git:(feature/kubernetes) aws s3api create-bucket --bucket twfulfillment-k8s-uat --region us-east-1
{
    "Location": "/twfulfillment-k8s-uat"
}
➜  etc git:(feature/kubernetes) aws s3api create-bucket --bucket twfulfillment-k8s-dev --region us-east-1
{
    "Location": "/twfulfillment-k8s-dev"
}
➜  etc git:(feature/kubernetes) aws s3api create-bucket --bucket twfulfillment-k8s-prod --region us-east-2  --create-bucket-configuration LocationConstraint=us-east-2
{
    "Location": "http://twfulfillment-k8s-prod.s3.amazonaws.com/"
}
 
➜  etc git:(feature/kubernetes) aws s3api list-buckets
{
    "Buckets": [
        {
            "Name": "twfulfillment-k8s-dev",
            "CreationDate": "2018-05-07T15:34:10.000Z"
        },
        {
            "Name": "twfulfillment-k8s-prod",
            "CreationDate": "2018-05-07T15:34:29.000Z"
        },
        {
            "Name": "twfulfillment-k8s-uat",
            "CreationDate": "2018-05-07T15:33:55.000Z"
        }

    }
}
 
## Enable versioning on all 3
➜  etc git:(feature/kubernetes) aws s3api put-bucket-versioning --bucket twfulfillment-k8s-prod  --versioning-configuration Status=Enabled
➜  etc git:(feature/kubernetes) aws s3api put-bucket-versioning --bucket twfulfillment-k8s-uat  --versioning-configuration Status=Enabled
➜  etc git:(feature/kubernetes) aws s3api put-bucket-versioning --bucket twfulfillment-k8s-dev  --versioning-configuration Status=Enabled
 
## ... and verify
➜  etc git:(feature/kubernetes) aws s3api get-bucket-versioning --bucket twfulfillment-k8s-dev
{
    "Status": "Enabled"
}
➜  etc git:(feature/kubernetes) aws s3api get-bucket-versioning --bucket twfulfillment-k8s-uat
{
    "Status": "Enabled"
}
➜  etc git:(feature/kubernetes) aws s3api get-bucket-versioning --bucket twfulfillment-k8s-prod
{
    "Status": "Enabled"
}

Set up cluster using kops

From now on, make SURE the AWS_xxx env variables are defined.

Generate key pairs

➜  etc git:(feature/kubernetes) cd k8s
➜  k8s git:(feature/kubernetes) ll
 
## Location of keys for DEV and UAT. See
➜  k8s git:(feature/kubernetes) pwd
/Users/miro/src/TWC/fragrm-integ/etc/k8s
 
##
ssh-keygen -t rsa -C twfulfillment-dev-ssh
ssh-keygen -t rsa -C twfulfillment-uat-ssh

ssh-keygen -t rsa -C twfulfillment-prod-ssh

## Check the keys 
➜  k8s git:(feature/kubernetes) ✗ ll

Creating the clusters

We will be creating 2 clusters in us-east-1

The instances used will be 3x t2.medium per cluster - 1x master + 2 worker nodes. We need t2.medium for Java processes and Kuberneters recommends the master to be at least t2.medium (or t2.large for larger number of worker nodes).

The command

kops create cluster --zones us-east-1a,us-east-1b --name twfulfillment-uat.k8s.local --ssh-public-key=./twfulfillment-uat-ssh.pub --state=s3://twfulfillment-k8s-uat --kubernetes-version 1.9.3 --node-count 2 --node-size t2.medium --master-size t2.medium

kops has set your kubectl context to twfulfillment-uat.k8s.local
 
Cluster is starting.  It should be ready in a few minutes.
 
Suggestions:
 * validate cluster: kops validate cluster
 * list nodes: kubectl get nodes --show-labels
 * ssh to the master: ssh -i ~/.ssh/id_rsa admin@api.twfulfillment-uat.k8s.local
 * the admin user is specific to Debian. If not using Debian please use the appropriate user based on your OS.
 * read about installing addons at: https://github.com/kubernetes/kops/blob/master/docs/addons.md.
