Synopsis

The code is for setting up a devops enviroment using latest Sonarqube, Nexus (or artifactory) and Jenkins on a small kubernetes cluster

YOu can either run the script to install Sonarqube, Nexus and Jenkins or pick and choose which one you want

Steps

Install Juju

https://jujucharms.com/docs/2.3/reference-install

Setup Juju (only if you never used it before)

$ juju clouds
# Pick your cloud providers and add credentials
$ juju add-credential aws
$ juju bootstrap aws YOUR_CREDENTIAL_NAME

Install Kubernetes with Juju

$ juju add-model mydevops YOUR_AWS_REGION
$ juju deploy kubernetes-core --constraints 'instance-type=t2.medium'

You can adapt to the instances of your choice

$ watch -c juju status --color - wait that everything is green
$ mkdir -p ~/.kube
$ juju scp kubernetes-master/0:config ~/.kube/config

# Query the cluster.
$ kubectl cluster-info

Accessing the Kubernetes Dashboard

The Kubernetes dashboard addon is installed by default, along with Heapster, Grafana and InfluxDB for cluster monitoring. The dashboard addons can be enabled or disabled by setting the enable-dashboard-addons config on the kubernetes-master application:

$ juju config kubernetes-master enable-dashboard-addons=true

To access the dashboard, you may establish a secure tunnel to your cluster with the following command:

$ kubectl proxy

By default, this establishes a proxy running on your local machine and the kubernetes-master unit. To reach the Kubernetes dashboard, visit http://localhost:8001/ui

Option 1 - Install SonarQube+Jenkins+Nexus

$ ./kubernetes-devops.sh
# Verify that the pods is up
$ kubectl get pods
# To get your Jenkins admin password
$ kubectl logs JENKINS_POD

Option 2 - Install each component one by one

Install Jenkins

# Create Jenkins deployment
$ kubectl create -f jenkins-deployment.yml
# Verify that the pod is up
$ kubectl get pods | grep jenkins
# Create Jenkins service
$ kubectl create -f jenkins-service.yml
# Check service is up
$ kubectl get svc jenkins
$ kubectl describe  svc jenkins | grep NodePort
# To get your Jenkins admin password
$ kubectl logs JENKINS_POD_NAME  | grep -B2 AdminPassword

Open the NodePort in the security group

Install SonarQube

# Create SonarQube deployment
$ kubectl create -f sonar-deployment.yml
# Verify that the pod is up
$ kubectl get pods | grep sonar
# Create SonarQube service
$ kubectl create -f sonar-service.yml
$ kubectl get svc sonar
$ kubectl describe  svc sonar | grep NodePort

Open the NodePort in the security group

Install Nexus Repository Manager 3

# Create Nexus 3 deployment
$ kubectl create -f nexus3-deployment.yml
# Verify that the pod is up
$ kubectl get pods | grep nexus3
# Create Nexus 3 service
$ kubectl create -f nexus3-service.yml
$ kubectl get svc sonar
$ kubectl describe  svc nexus3 | grep NodePort

Open the NodePort in the security group

Install Artifactory

The following describes the steps to do the actual deployment of the Artifactory and its services to Kubernetes.

Preparing Resources

Need to create some resources that will be used by Nginx as SSL and Artifactory reverse proxy configuration

Docker registry secret (optional)

In case you built your own Artifactory image and pushed it to your private registry, you might need to define a docker-registry secret to be used by Kubernetes to pull images

$ kubectl create secret docker-registry docker-reg-secret --docker-server=${YOUR_DOCKER_REGISTRY} --docker-username=${USER} --docker-password=${PASSWORD} [email protected]

SSL secret

Create the SSL secret that will be used by the Nginx pod

$ kubectl create secret tls art-tls --cert=${PATH_TO_CERT}/myssl.pem --key=${PATH_TO_CERT}/myssl.key

Database (using PostgreSQL)

# Create an EBS in the availability zone of your choice (note the volumeid)
$ aws ec2 create-volume --availability-zone ap-northeast-1a --size 6 --volume-type gp2
# Update postgresql-pv.yml with  your volumeid
$ kubectl apply -f postgresql-pv.yml
$ kubectl apply -f postgresql-storage.yml
$ kubectl apply -f postgresql-service.yml

Artifactory

# Create an EBS in the availability zone of your choice (note the volumeid)
$ aws ec2 create-volume --availability-zone ap-northeast-1a --size 6 --volume-type gp2
# Update artifactory-pv.yml with  your volumeid
$ kubectl apply -f artifactory-pv.yml
$ kubectl apply -f artifactory-storage.yml
$ kubectl apply -f artifactory-service.yml

Nginx

# Configuration
$ kubectl create configmap nginx-artifactory-conf --from-file=artifactory.conf
# Create an EBS in the availability zone of your choice (note the volumeid)
$ aws ec2 create-volume --availability-zone ap-northeast-1a --size 2 --volume-type gp2
# Update nginx-pv.yml with  your volumeid
$ kubectl apply -f nginx-pv.yml
$ kubectl apply -f nginx-storage.yml
$ kubectl apply -f nginx-deployment.yml
# Nginx service
$ kubectl apply -f nginx-service.yml

Final Check

# Get pods and their status
$ kubectl get pods
# Get services
$ kubectl get services
