Terraformed environments design and build (IaC)

[olivierlemee]

TASKS

Construire IaC terraform chaque cluster infrastructure (dev, test, perf, prod) instanciation en auto sur cloud (ovh) avec configuration des services/ressources allouées (par helm)

• Créer pipeline spinnaker de patching/reconstruction pour stratégie canary en cas d’évolution de composants d’infra, qui pilote terraform/helm pour actualiser une infra cible

TARGETED GOALS

K8S infrastructure as a code (terraform)
o Use Terraform (IaC Infrastructure as a Code, config mgt and provisioning) to create and manage Helm resources, and to create a kubernetes cluster (see Terraform vs. Helm for Kubernetes - DZone Cloud)
o Cluster structure is ready to be built
· Built K8S cluster and services provisioned (terraform)
o Deploy Helm charts (helm manifest regarding infrastructure stack) to a pre-provisioned Kubernetes (orchestration and scheduling) cluster with Terraform
o Cluster instance is running with active services
o Prod, Test, Pre-prod,… environnement is runnins as a K8S cluster on a Cloud (ex OVH)

Tools Description
Terraform (manage and automate infrastructure, platforms, and services. The tool helps build, change, and version infrastructure through code):

• Spin up virtual machines and containers.
• Set up servers.
• Create security schemes and controls.
• Add or remove users and set permissions.
• Manage cloud resources.
• Install and manage Docker containers.
  

Helm (Kubernetes package manager ideal for deploying repeatable apps and services to clusters ;, This tool allows users to manage apps via Helm Charts that simplify defining, installing, and upgrading K8s environments) :

• Deploy and manage K8s manifests in different environments.
• Package complex applications together.
• Rollback or upgrade multiple objects together.
• Quickly change setup parameters.
• Deploy to multiple environments with a single command.
