Chapter 5 ■ Using the Tectonic Console
Overview
The Console can be used to deploy new applications, create rolling upgrades for deployments, and create
pods, replication controllers and services. We’ll explore the following topics:
Setting the environment
Downloading the pull secret and the Tectonic Console manifest
Installing the pull secret and the Tectonic Console
Accessing the Tectonic Console
Using the Tectonic Console
Removing the Tectonic Console
Setting the Environment
As a prerequisite, install a Kubernetes cluster. Installing Kubernetes on CoreOS on the AWS cloud provider
is discussed in Chapter 2. To reiterate briefly, first create an Amazon EC2 instance to launch an AWS
CloudFormation for a Kubernetes cluster. The EC2 instance AMI should be Amazon Linux, as Amazon Client
Interface (CLI) is preinstalled on an Amazon Linux AMI-based instance. Obtain the public IP address of the
EC2 instance and SSH log in to the instance. Create a CloudFormation for a Kubernetes cluster consisting of
one master and three worker nodes as shown in Figure 5-1.
Figure 5-1. CloudFormation EC2 instances for a Kubernetes cluster
Obtain the public IP address for the controller from the EC2 console and add an A record for the
IP address to the public DNS used to initialize the CloudFormation stack as shown in Figure 5-2.
