Configure

The configuration step in the DevOps toolchain will be covered. Also including any core infrastructure links in this page.

Kubernetes/Container

Kubernetes(k8s) is the best modern approach for deploying and maintaining code.

Infrastructure As Code

• CrossPlane: Infrastructure provider as k8s resources
  • Is Crossplane the Infrastructure LLVM?
• Terraform: A very popular IaC platform
  • tf-free: Provision free-tier resources across a variety of cloud providers.
  • Infracost: Terraform Infrastructure Cost estimation, which can be baked into a CD pipeline for better review of what infrastructure costs will be.
  • Terraservice: A model for services in Terraform
  • Terracognita: Generate IaC from existing code.
  • Terraformer: Produce terraform from existing resources.
  • Testing Terraform with pytest - an Interesting concept to directly test against the Terraform state file, versus something like Terratest that actually builds out infrastructure.
  • Moving Away From CDK - SST’s reasoning for moving away from AWS SDK/CloudFormation
• Cloud Instance Cost
  • AWS: Vantage Instance Cost: Used to be EC2Instances.info, but Vantage is now hosting. Source is still on Github
  • Azure: Azureprice.net Great info. Unfortunately source is not available.

Amazon Web Services (AWS)

• AWS NAT Gateway Alternative #1 - AlterNAT: Redundant, but self managed (although Terraform and Lambdas cover most use-cases)
• AWS NAT Gateway Alternative #2 - fck-nat: Simplier solution

System Build Tool

• Packer: Designed to quickly deploy test virtual machines in a specific configuration. Can pull in external configuration management such as Ansible if desired.
• ClusterAPI: Kubernetes focused provisioning.
• Tinkerbell: Provision and Manange Bare Metal Anywhere

Configuration Management

Configuration Management: Generally an anti-pattern. Much prefer leveraging Packer to build immutable images, and Terraform or Crossplane to deploy

• Ansible:
  • Ansible: Ansible core project
  • AnsiJet: Ansible playbook automation server. Provides a REST API and playbook results storage in MongoDB.
• Jenkins: Generally used for CI on code, could be integrated with the above to perform full integration testing on a stack

DNS

• IpIFY: Light-weight API to get your public IP address. Basic IP info is free to use. Can register to get GeoIP Information.
• ip-api.com. Provids IP, geo-location and ISP information at http://ip-api.com/json Free for non-commercial purposes.
• NoIP and XIP: Automatic DNS based on IP address
