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 kube-up.sh script from the Kubernetes binary download at github.com/kubernetes/kubernetes/releases/download/v1.4.0/kubernetes.tar.gz 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 Kubernetes slack channel for helping me through the details!
Download kops and kubectl
- Download Kops latest release. This blog was tested with 1.4.1 on OSX.Complete set of commands for
kopscan be seen:
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
kubectlin yourPATH.
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.medomain. 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
Created zone looks like:
👁 kops-hosted-zone-created-1024x275
The values shown in the Value column are important as they’ll be used later for creating NS records.
- Create a S3 bucket using Amazon Console to store cluster configuration – this is called
state store.
- The domain
kubernetes.arungupta.meis 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-record-1024x588
For each value, add the record as shown:
👁 kops-godaddy-add-zone-record-1024x588
Completed set of records look
👁 kops-godaddy-add-ns-record-1024x980
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=awsis optional if cloud can be inferred from zones--yesis 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.
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. --associate-public-ip Specify --associate-public-ip=[true|false] to enable/disable association of public IP for master ASG and nodes. Default is 'true'. (default true) --channel string Channel for default versions and configuration to use (default "stable") --cloud string Cloud provider to use - gce, aws --dns-zone string DNS hosted zone to use (defaults to last two components of cluster name) --image string Image to use --kubernetes-version string Version of kubernetes to run (defaults to version in channel) --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 --out string Path to write any local output --project string Project to use (must be set on GCE) --ssh-public-key string SSH public key to use (default "~/.ssh/id_rsa.pub") --target string Target - direct, terraform (default "direct") --vpc string Set to use a shared VPC --yes Specify --yes to immediately create the cluster --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 --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
- 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:
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 at github.com/arun-gupta/kubernetes-java-sample/blob/master/maven/couchbase-service.yml.
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 at github.com/arun-gupta/kubernetes-java-sample/blob/master/maven/bootiful-couchbase.yml.
See 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
