Multimaster Kubernetes Cluster on Amazon Using Kops

DZone's Guide to

Multimaster Kubernetes Cluster on Amazon Using Kops

Check out how to use Kops — short for Kubernetes Operations — to help get your Kubernetes clusters up and running on Amazon.

Insight into the right steps to take for migrating workloads to public cloud and successfully reducing cost as a result. Read the Guide.

Getting Started with Kubernetes 1.4 using Spring Boot and Couchbase explains how to get started with Kubernetes  1.4 on Amazon Web Services. A Couchbase service is created in the cluster and a Spring Boot application stores a JSON document in the database. It uses a kube-up.sh script from the Kubernetes binary download at to start the cluster. This script is capable of creating a Kubernetes cluster with single master only. This is a fundamental flaw of distributed applications where the master becomes a Single Point of Failure.

Meet kops – short for Kubernetes Operations.

This is the easiest way to get a highly-available Kubernetes cluster up and running. The kubectl script is the CLI for running commands against running clusters. Think of kops as kubectl for cluster.

This blog will show how to create a highly-available Kubernetes cluster on Amazon using kops. And once the cluster is created, then it’ll create a Couchbase service on it and run a Spring Boot application to store JSON document in the database.

Many thanks to justinsb, sarahz, razic, jaygorrell, shrugs, bkpandey, and others at the Kubernetes slack channel for helping me through the details!

Download Kops and Kubectl

  • Download the latest Kops release. This blog was tested with 1.4.1 on OSX. The complete set of commands for kops can be seen:
kops-darwin-amd64 --help
kops is kubernetes ops.
It allows you to create, destroy, upgrade and maintain clusters.

Usage:
  kops [command]

Available Commands:
  create         create resources
  delete         delete clusters
  describe       describe objects
  edit           edit items
  export         export clusters/kubecfg
  get            list or get objects
  import         import clusters
  rolling-update rolling update clusters
  secrets        Manage secrets & keys
  toolbox        Misc infrequently used commands
  update         update clusters
  upgrade        upgrade clusters
  version        Print the client version information

Flags:
      --alsologtostderr                  log to standard error as well as files
      --config string                    config file (default is $HOME/.kops.yaml)
      --log_backtrace_at traceLocation   when logging hits line file:N, emit a stack trace (default :0)
      --log_dir string                   If non-empty, write log files in this directory
      --logtostderr                      log to standard error instead of files (default false)
      --name string                      Name of cluster
      --state string                     Location of state storage
      --stderrthreshold severity         logs at or above this threshold go to stderr (default 2)
  -v, --v Level                          log level for V logs
      --vmodule moduleSpec               comma-separated list of pattern=N settings for file-filtered logging

Use "kops [command] --help" for more information about a command.

  • Download kubectl:
curl -Lo kubectl http://storage.googleapis.com/kubernetes-release/release/v1.4.1/bin/darwin/amd64/kubectl && chmod +x kubectl

  •  Include kubectl in your PATH.

Create Bucket and NS Records on Amazon

There is a bit of setup involved at this time, and hopefully this will get cleaned up over next releases. Bringing up a cluster on AWS provide detailed steps and more background. Here is what the blog followed:

  • Pick a domain where Kubernetes cluster will be hosted. This blog uses kubernetes.arungupta.me domain. You can pick a top level domain or a sub-domain.
  • Amazon Route 53 is a highly available and scalable DNS service. Login to Amazon Console and created a hosted zone for this domain using Route 53 service.kops-hosted-zoneCreated zone looks like:kops-hosted-zone-createdThe values shown in the Value column are important as they’ll be used later for creating NS records.
  • Create an S3 bucket using Amazon Console to store cluster configuration – this is called state store.kops-s3-bucket
  • The domain kubernetes.arungupta.me is hosted on GoDaddy. For each value shown in the Value column of Route53 hosted zone, create a NS record using GoDaddy Domain Control Center for this domain.Select the type of record:kops-godaddy-add-zone-recordFor each value, add the record as shown:kops-godaddy-add-ns-recordCompleted set of records look like:kops-godaddy-ns-records

Start Kubernetes Multimaster Cluster

Let’s understand a bit about Amazon regions and zones:

Amazon EC2 is hosted in multiple locations world-wide. These locations are composed of regions and Availability Zones. Each region is a separate geographic area. Each region has multiple, isolated locations known as Availability Zones.

A highly-available Kubernetes cluster can be created across zones but not across regions.

  • Find out availability zones within a region:
aws ec2 describe-availability-zones --region us-west-2
{
    "AvailabilityZones": [
        {
            "State": "available", 
            "RegionName": "us-west-2", 
            "Messages": [], 
            "ZoneName": "us-west-2a"
        }, 
        {
            "State": "available", 
            "RegionName": "us-west-2", 
            "Messages": [], 
            "ZoneName": "us-west-2b"
        }, 
        {
            "State": "available", 
            "RegionName": "us-west-2", 
            "Messages": [], 
            "ZoneName": "us-west-2c"
        }
    ]
}


  • Create a multi-master cluster:
kops-darwin-amd64 create cluster --name=kubernetes.arungupta.me --cloud=aws --zones=us-west-2a,us-west-2b,us-west-2c --master-size=m4.large --node-count=3 --node-size=m4.2xlarge --master-zones=us-west-2a,us-west-2b,us-west-2c --state=s3://kops-couchbase --yes

    Most of the switches are self-explanatory. Some switches need a bit of explanation:
    • Specifying multiple zones using --master-zones (must be odd number) create multiple masters across AZ.
    • --cloud=aws is optional if cloud can be inferred from zones.
    • --yes is used to specify the immediate creation of cluster. Otherwise only the state is stored in the bucket, and the cluster needs to be created separately.
    The complete set of CLI switches can be seen: 
./kops-darwin-amd64 create cluster --help
Creates a k8s cluster.

Usage:
  kops create cluster [flags]

Flags:
      --admin-access string         Restrict access to admin endpoints (SSH, HTTPS) to this CIDR.  If not set, access will not be restricted by IP.

      --master-size string          Set instance size for masters
      --master-zones string         Zones in which to run masters (must be an odd number)
      --model string                Models to apply (separate multiple models with commas) (default "config,proto,cloudup")
      --network-cidr string         Set to override the default network CIDR
      --networking string           Networking mode to use.  kubenet (default), classic, external. (default "kubenet")
      --node-count int              Set the number of nodes
      --node-size string            Set instance size for nodes

      --zones string                Zones in which to run the cluster

Global Flags:
      --alsologtostderr                  log to standard error as well as files
      --config string                    config file (default is $HOME/.kops.yaml)
      --log_backtrace_at traceLocation   when logging hits line file:N, emit a stack trace (default :0)
      --log_dir string                   If non-empty, write log files in this directory
      --logtostderr                      log to standard error instead of files (default false)
      --name string                      Name of cluster

      --vmodule moduleSpec               comma-separated list of pattern=N settings for file-filtered logging


    Once the cluster is created, get more details about the cluster:

kubectl cluster-info
Kubernetes master is running at https://api.kubernetes.arungupta.me
KubeDNS is running at https://api.kubernetes.arungupta.me/api/v1/proxy/namespaces/kube-system/services/kube-dns

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.


Check cluster client and server version:

kubectl version
Client Version: version.Info{Major:"1", Minor:"4", GitVersion:"v1.4.1", GitCommit:"33cf7b9acbb2cb7c9c72a10d6636321fb180b159", GitTreeState:"clean", BuildDate:"2016-10-10T18:19:49Z", GoVersion:"go1.7.1", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"4", GitVersion:"v1.4.3", GitCommit:"4957b090e9a4f6a68b4a40375408fdc74a212260", GitTreeState:"clean", BuildDate:"2016-10-16T06:20:04Z", GoVersion:"go1.6.3", Compiler:"gc", Platform:"linux/amd64"}

  • Check all nodes in the cluster:
kubectl get nodes 
NAME                                           STATUS    AGE
ip-172-20-111-151.us-west-2.compute.internal   Ready     1h
ip-172-20-116-40.us-west-2.compute.internal    Ready     1h
ip-172-20-48-41.us-west-2.compute.internal     Ready     1h
ip-172-20-49-105.us-west-2.compute.internal    Ready     1h
ip-172-20-80-233.us-west-2.compute.internal    Ready     1h
ip-172-20-82-93.us-west-2.compute.internal     Ready     1h


Or find out only the master nodes:

kubectl get nodes -l kubernetes.io/role=master
NAME                                           STATUS    AGE
ip-172-20-111-151.us-west-2.compute.internal   Ready     1h
ip-172-20-48-41.us-west-2.compute.internal     Ready     1h
ip-172-20-82-93.us-west-2.compute.internal     Ready     1h

  • Check all the clusters:
kops-darwin-amd64 get clusters --state=s3://kops-couchbase
NAME            CLOUD    ZONES
kubernetes.arungupta.me    aws    us-west-2a,us-west-2b,us-west-2c

Kubernetes Dashboard Addon

By default, a cluster created using kops does not have the UI dashboard. But this can be added as an add-on:

kubectl create -f https://raw.githubusercontent.com/kubernetes/kops/master/addons/kubernetes-dashboard/v1.4.0.yaml
deployment "kubernetes-dashboard-v1.4.0" created
service "kubernetes-dashboard" created


Now complete details about the cluster can be seen:

kubectl cluster-info
Kubernetes master is running at https://api.kubernetes.arungupta.me
KubeDNS is running at https://api.kubernetes.arungupta.me/api/v1/proxy/namespaces/kube-system/services/kube-dns
kubernetes-dashboard is running at https://api.kubernetes.arungupta.me/api/v1/proxy/namespaces/kube-system/services/kubernetes-dashboard

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.


And the Kubernetes UI dashboard is at the shown URL. In our case, this is https://api.kubernetes.arungupta.me/ui and looks like:

kops-kubernetes-ui

Credentials for accessing this dashboard can be obtained using the kubectl config view command. The values are shown like:

- name: kubernetes.arungupta.me-basic-auth
  user:
    password: PASSWORD
    username: admin


Deploy Couchbase Service

As explained in Getting Started with Kubernetes 1.4 using Spring Boot and Couchbase, let’s run a Couchbase service:

kubectl create -f ~/workspaces/kubernetes-java-sample/maven/couchbase-service.yml 
service "couchbase-service" created
replicationcontroller "couchbase-rc" created


This configuration file is here.

Get the list of services:

kubectl get svc
NAME                CLUSTER-IP     EXTERNAL-IP   PORT(S)                                AGE
couchbase-service   100.65.4.139   <none>        8091/TCP,8092/TCP,8093/TCP,11210/TCP   27s
kubernetes          100.64.0.1     <none>        443/TCP                                2h


Describe the service:

kubectl describe svc/couchbase-service
Name:            couchbase-service
Namespace:        default
Labels:            <none>
Selector:        app=couchbase-rc-pod
Type:            ClusterIP
IP:            100.65.4.139
Port:            admin    8091/TCP
Endpoints:        100.96.5.2:8091
Port:            views    8092/TCP
Endpoints:        100.96.5.2:8092
Port:            query    8093/TCP
Endpoints:        100.96.5.2:8093
Port:            memcached    11210/TCP
Endpoints:        100.96.5.2:11210
Session Affinity:    None


Get the pods:

kubectl get pods
NAME                 READY     STATUS    RESTARTS   AGE
couchbase-rc-e35v5   1/1       Running   0          1m


Run Spring Boot Application

The Spring Boot application runs against the Couchbase service and stores a JSON document in it.

Start the Spring Boot application:

kubectl create -f ~/workspaces/kubernetes-java-sample/maven/bootiful-couchbase.yml 
job "bootiful-couchbase" created


This configuration file is here.

See a list of all the pods:

kubectl get pods --show-all
NAME                       READY     STATUS      RESTARTS   AGE
bootiful-couchbase-ainv8   0/1       Completed   0          1m
couchbase-rc-e35v5         1/1       Running     0          3m


Check logs of the complete pod:

kubectl logs bootiful-couchbase-ainv8
