DevOps Tools & Technologies

The order to learn these in

Roughly one to three weeks per step, depending on how much time you get. Resist skipping ahead; each step is a prerequisite for the next in a way that only becomes obvious when you have skipped it.

1. 1.Linux — everything else runs on it. Files and permissions, processes, logs, networking basics, enough shell to automate a repetitive task. This is the single highest-return thing on the list and the most commonly rushed.
2. 2.Git — branching, merging, and resolving a conflict without panicking. Every pipeline you build later is triggered by a Git event, so a shaky mental model here creates confusion everywhere downstream.
3. 3.Docker — images, containers, volumes, networks, Compose. Comfortable here means Kubernetes later will make sense rather than feel arbitrary.
4. 4.CI/CD — now you can automate building and shipping the container you just learned to make. Jenkins or GitHub Actions; the concepts carry across either.
5. 5.Infrastructure as code, then Terraform — the concept before the tool. Understanding state and idempotency is what stops Terraform from feeling like magic that occasionally destroys a database.
6. 6.Kubernetes — only now. With Linux, containers and pipelines behind you, pods and deployments read as sensible solutions to problems you have personally hit.
7. 7.Monitoring and logging — last in the sequence, first in importance once you are employed. Prometheus, Grafana and log aggregation are how you find out something broke before a customer tells you.

If you want the same sequence with timelines and projects attached, the beginner DevOps roadmap lays it out week by week.
