How long does it take to become a DevOps engineer?
With a developer or sysadmin background, many people are ready for a junior DevOps role in about 6 to 12 months of focused hands-on work. Starting from zero usually takes longer, often 12 to 24 months, because Linux, networking and coding come first. The time depends less on courses and more on how many real systems you have set up and debugged.
Months 1 to 3 - Linux, networking and Git
Work in the Linux shell every day: files, permissions, processes, systemd services and logs. Learn ports, DNS and HTTP, and use curl and ss. Use Git for everything. Write small Bash scripts. Build: a web server with nginx, a systemd service for a small app, a script that checks if a service is up.
Months 4 to 6 - containers and CI/CD
Learn Docker: build images, write a good Dockerfile, use Compose for an app and a database. Build a CI pipeline in GitHub Actions that tests and builds the app. Learn one cloud provider (AWS is a common choice) - IAM, S3, EC2. Build: a production Dockerfile, a pipeline that pushes an image, a database backup to S3.
Months 7 to 12 - infrastructure as code and Kubernetes
Write Terraform for real cloud resources and learn plans and state. Deploy apps to Kubernetes with Deployments, Services and ConfigMaps. Add monitoring with Prometheus and Grafana. Build: Terraform for an S3 bucket and an EC2 instance, an app on Kubernetes, an alert that fires on a real problem. Start applying once you have 3 to 5 projects.
What makes it faster
Hands-on work on running systems moves faster than watching videos. Each problem you debug - a service that will not start, a port that is closed, a pipeline that fails - teaches you something that sticks. On HeyDevJob, the Free plan covers 5 Junior projects a month in live cloud workspaces, which fits the first stages of this plan.

Related questions
Can I become a DevOps engineer in 3 months?
Only if you already have strong Linux and coding skills, for example as a sysadmin or developer. From zero, 3 months is enough for the foundations, not for a job.
How many hours a week should I study?
Consistency matters more than total hours. 10 to 15 focused hours a week of hands-on work is a realistic pace for people with a job.
Should I start in another role and move to DevOps?
Many people do. Support, sysadmin and backend roles give you real experience with servers and deploys, which makes the move easier.
