DevOps is a critical methodology combining software development (Dev) and IT operations (Ops) to shorten the development lifecycle while delivering high-quality software. Sandip Das’ 60 Days of DevOps initiative is a structured learning path for mastering DevOps, Cloud, and Coding. Below is an extended guide with practical commands, tools, and steps to reinforce your DevOps journey.
You Should Know:
1. Essential DevOps Tools & Commands
Git (Version Control)
git clone <repository-url> Clone a repository git checkout -b <branch-name> Create and switch to a new branch git add . Stage all changes git commit -m "Commit message" Commit changes git push origin <branch-name> Push changes to remote
Docker (Containerization)
docker build -t <image-name> . Build a Docker image docker run -d -p 8080:80 <image-name> Run a container in detached mode docker ps List running containers docker logs <container-id> Check container logs
Kubernetes (Orchestration)
kubectl get pods List all pods kubectl apply -f deployment.yaml Deploy a configuration kubectl describe pod <pod-name> Inspect pod details kubectl logs <pod-name> Fetch pod logs
Terraform (Infrastructure as Code)
terraform init Initialize Terraform terraform plan Preview changes terraform apply Apply changes terraform destroy Tear down infrastructure
CI/CD with Jenkins
jenkins-job-build <job-name> Trigger a Jenkins job
2. Cloud (AWS) Commands
aws s3 ls List S3 buckets aws ec2 describe-instances Check EC2 instances aws lambda list-functions List Lambda functions
3. Linux SysAdmin Essentials
top Monitor system processes df -h Check disk space grep "error" /var/log/syslog Search logs for errors chmod 755 script.sh Change file permissions
4. Windows DevOps Commands
Get-Service List all services Test-NetConnection -ComputerName google.com -Port 80 Check connectivity
What Undercode Say
DevOps is not just about tools—it’s a culture of automation, collaboration, and continuous improvement. Mastering these commands and workflows will streamline deployments, enhance security, and optimize infrastructure. The 60 Days of DevOps challenge is a great way to build expertise systematically.
Prediction
As DevOps evolves, expect deeper AI/ML integration in CI/CD pipelines, more GitOps adoption, and increased focus on security (DevSecOps). Cloud-native tools like Kubernetes and serverless computing will dominate.
Expected Output:
- Faster deployment cycles
- Automated infrastructure management
- Improved collaboration between Dev & Ops teams
- Scalable, resilient cloud architectures
