Implementing full automation for provisioning multi-cloud OpenShift clusters

Managing large clusters with significant gaps in automation.
Réalisation
Implementing a software engineering approach to infrastructure.
A critical component of this initiative was the implementation of Tekton pipelines for deploying and managing full OpenShift clusters (up to 50 nodes per cluster) on AWS and Azure. These pipelines run nightly to continuously verify the integrity of the clusters. The entire infrastructure was provisioned and managed through Terraform manifests, utilizing a layered architecture.
Another key aspect of the project was the development of a custom Terraform provider in Go, designed to manage an internal tool crucial for cluster management. Furthermore, tools were developed with Ansible to enable the team to easily manage their OpenShift resources, ensuring simplified and automated infrastructure management.
