Google Kubernetes + OpenContrail SDN

Quickly bringup a Kubernetes cluster with OpenContrail SDN on different clouds (AWS/Azure/GCP/OpenStack)

AWS CloudFormation

AWS CloudFormation provides a common language for you to describe and provision all the infrastructure resources in your cloud environment. CloudFormation allows you to use a simple text file to model and provision, in an automated and secure manner, all the resources needed for your applications across all regions and accounts. This file serves as the single source of truth for your cloud environment.

• Red Hat OpenShift with OpenContrail SDN

  

HashiCorp Terraform

HashiCorp Terraform enables you to safely and predictably create, change, and improve infrastructure. It is an open source tool that codifies APIs into declarative configuration files that can be shared amongst team members, treated as code, edited, reviewed, and versioned.

  Download Terraform

      (host)# ssh-keygen -b 2048 -t rsa -f .ssh/terraform
      (host)# git clone https://github.com/savithruml/cloud-ops
      (host)# cd cloud-ops/aws/terraform/k8s
      (host)# vi terraform.tfvars
  
           ...
                # AWS access key
                aws_access_key            = "<access-key>"
  
                # AWS secret key
                aws_secret_key            = "<secret-key>"
           ...
  
      (host)# terraform apply
  

Red Hat Ansible

Red Hat® Ansible makes it easy to scale automation, manage complex deployments and speed productivity. Extend the power of Ansible with workflows to streamline jobs and simple tools to share solutions with your team.

  1. Bring your ansible node. This node can either sit indide the AWS environment or outside

      (ansible-node)# apt-get update -y && apt-get install python python-pip -y
      (ansible-node)# pip install -U ansible boto boto3
     
      (ansible-node)# cd /root
      (ansible-node)# git clone https://github.com/savithruml/ansible-labs
     

  2. Populate /root/ansible-labs/aws/playbooks/group_vars/all file with AWS creds & cluster info

      (ansible-node)# cat /root/ansible-labs/aws/playbooks/group_vars/all
      
            aws_access_key: <key-here> 
            aws_secret_key: <secret-key-here>
            key_name: <key>
            aws_region: <region>
            vpc_id: <vpc>
            vpc_subnet_id: <subnet>
            ami_id: <image>
            instance_type: <flavor>
            count: 2
            ec2_tag: contrail-k8s
           
      (ansible-node)# cd /root/ansible-labs/aws       
      (ansible-node)# ansible-playbook -i inventory/hosts playbooks/deploy-vms.yml
     

     This should bring up 2 instances in AWS with root password set to "c0ntrail123"

  3. Prepare nodes for deployment

  4. Run these commands on all nodes. This will enable root access with password

      (all-nodes)# sudo su
      (all-nodes)# sed -i -e 's/#PermitRootLogin yes/PermitRootLogin yes/g' -e 's/PasswordAuthentication no/PasswordAuthentication yes/g' /etc/ssh/sshd_config 
      (all-nodes)# service sshd restart
     

  5. Logout & login as root user

      (ansible-node)# ssh-keygen –t rsa
      (ansible-node)# ssh-copy-id root@<k8s-master>
      (ansible-node)# ssh-copy-id root@<k8s-node>
     

  6. Populate /root/ansible-labs/k8s/hosts with k8s-master & k8s-node info

      (ansible-node)# cat /root/ansible-labs/k8s/hosts
     
         [masters]
         10.10.10.1
     
         [nodes]
         10.10.10.2
     

  7. Run the play

      (ansible-node)# cd /root/ansible-labs/k8s
      (ansible-node)# ansible-playbook -i hosts site.yml
     

OpenStack Heat

OpenStack Heat is a service in OpenStack to orchestrate composite cloud applications using a declarative template format through an OpenStack-native REST API.

        (openstack-controller)# git clone https://github.com/savithruml/cloud-ops
        (openstack-controller)# cd cloud-ops/openstack/nested-k8s/provisioning/heat
        (openstack-controller)# vi /root/nested-mode-contrail-networking/provisioning/heat/deploy-nested.env
                       
              ...
                 parameters:
  
                 # FQDN of the public network
                 public_network_fqdn: "default-domain:admin:public"
  
                 # Name of the master instance
                 master_instance_name: "nested-master"
  
                 # IP address of the master instance
                 master_ip: "<master-instance-IPv4-address>"
              ...
        
        (openstack-controller)# heat stack-create nested -f deploy-nested.yaml -e deploy-nested.env
