Platform Engineering

Move away from SSHing into a server and typing commands, and learn to declare the state you want in code and let the tooling converge on it. You work by hand through ten courses: Ansible and OpenTofu, Kubernetes operations, Helm, CRDs and operators, Istio, GitOps, and policy engines. By the end you can turn an infrastructure change into reviewable work that records who changed what, when, and why.

코스

• Ansible Fundamentals — Stop SSHing into servers by hand.
• Ansible in Practice — Fold your copy-pasted playbooks into roles.
• Terraform/OpenTofu Fundamentals — Declare it, manage it as state, read the plan.
• Terraform in Practice — Handle modules, state and drift by hand.
• Kubernetes Operations — Only the things that page you at 3am.
• Kubernetes Distributions — Build Them Yourself — Stand up k3s and k0s, then restore etcd
• Authoring and Shipping Helm Charts — Write a chart yourself and roll back by revision.
• CRDs and Operators — Add your own type to the Kubernetes API.
• Istio Service Mesh — Take traffic and security out of your code.
• GitOps and Argo CD — Finish a deployment with one commit.
• Policy as Code — Carve the rules into the cluster, not into a document.
• GPU Operator and Time-Slicing — Starts from the incident that made four GPUs unusable at once.
