Tectonic Installer

 Install a Kubernetes cluster the CoreOS Tectonic Way。


Tectonic is built on pure-upstream Kubernetes but has an opinion on the best way to install and run a Kubernetes cluster. This project helps you install a Kubernetes cluster the "Tectonic Way". It provides good defaults, enables install automation, and is customizable to meet your infrastructure needs.
Goals of the project:
  • Installation of Self-Hosted Kubernetes Cluster
  • Secure by default (use TLS, RBAC by default, OIDC AuthN, etcd)
  • Automatable install process for scripts and CI/CD
  • Deploy Tectonic on any infrastructure (Amazon, Azure, OpenStack, GCP, etc)
  • Runs Tectonic on any OS (Container Linux, RHEL, CentOS, etc)
  • Customizable and modular (change DNS providers, security settings, etc)
  • HA by default (deploy all Kubernetes components HA, use etcd Operator)
Checkout the ROADMAP for details on where the project is headed.

Getting Started

To use a tested release on an supported platform, follow the links below.
To hack or modify the templates or add a new platform, use the scripts in this repo to boot and tear down clusters.

Official releases

See the official Tectonic documentation:

Hacking

These instructions can be used for the official stable platforms listed above, and for the following alpha/beta platforms:
Go and Source
Install Go if not already installed.
Then get the Tectonic Installer source code:
go get github.com/coreos/tectonic-installer
cd $(go env GOPATH)/src/github.com/coreos/tectonic-installer
Terraform
The Tectonic Installer releases include a build of Terraform. See the Tectonic Installer release notes for information about which Terraform versions are compatible.
The latest Terraform binary may not always work as Tectonic Installer, which sometimes relies on bug fixes or features not yet available in the official Terraform release.
Yarn (optional)
The Yarn JavaScript package manager is required for building the frontend code. On OS X, install via Homebrew: brew install yarn.

Common Usage

Choose your platform
First, set the PLATFORM= environment variable. This example will use PLATFORM=azure.
Initiate the Cluster Configuration
Using make create a new directory build/<cluster-name> to hold all module references, Terraform state files, and custom variable files.
PLATFORM=azure CLUSTER=my-cluster make localconfig
Configure Cluster
Set variables in the build/<cluster-name>/terraform.tfvars file as needed. Available variables are found in the platforms/<PLATFORM>/config.tf and platforms/<PLATFORM>/variables.tf files.
Examples for each platform can be found in the examples directory.
Terraform Lifecycle
Plan, apply, and destroy are provided as make targets to ease the build directory and custom binary complexity.
PLATFORM=azure CLUSTER=my-cluster make plan
PLATFORM=azure CLUSTER=my-cluster make apply
PLATFORM=azure CLUSTER=my-cluster make destroy

Tests

Tests are run for all approved pull requests via Jenkins. See the Jenkinsfile for details.
Tests can be run locally by:
AWS
export PLATFORM="aws"
export AWS_REGION="us-east-1"
export {TF_VAR_tectonic_cluster_name,CLUSTER}=my-smoke-test
export TF_VAR_tectonic_license_path=/path/to/license.txt
export TF_VAR_tectonic_pull_secret_path=/path/to/pull-secret.json

make localconfig
ln -sf ../../test/aws.tfvars build/${TF_VAR_tectonic_cluster_name}/terraform.tfvars
make plan
make apply
make destroy

Welcome to the Tectonic tutorials!

Thank you for your interest in CoreOS Tectonic. We hope you’re excited to learn how Tectonic works and how this self-driving Kubernetes solution can improve your organization’s application infrastructure.
To help you get up and running with Tectonic, we have designed these step-by-step tutorials. In them, we will walk you through:
  1. Creating an AWS account
  2. Downloading and installing Tectonic on AWS
  3. Using Tectonic
For the purpose of these exercises, we will lead you through the set-up process for AWS.

Creating your Tectonic account

If you haven’t already done so, you can create your Tectonic account now, or do it as you move through the tutorials. Tectonic is free for use of up to 10 nodes.
We will continue adding to these tutorials. Be sure to return and check for updates.
Let's Get Started
