🚀 Week 2 of My DevOps Journey: Virtual Machines & Automation
Mritunjay Tiwari
This week was all about virtualization and automation — diving into the world of Virtual Machines (VMs) and learning how to set them up manually and automatically using Chocolatey, Vagrant, VirtualBox, Git Bash, and SSH.
🔍 What I Learned This Week:
Understanding Virtual Machines and why they're crucial for DevOps.
Manual setup of VMs using VirtualBox:
- Installed CentOS Stream 9 and Ubuntu 24.04 LTS (Jellyfish Server).
Automation using:
Chocolatey – to install packages in Windows.
Vagrant – to create and configure VMs quickly.
Vagrant boxes – prepackaged development environments.
Git Bash – to manage, create, and delete VMs through the CLI.

🛠️ Tasks Completed:
✔️ Installed Chocolatey, Vagrant, and VirtualBox.
✔️ Manually created CentOS and Ubuntu VMs in VirtualBox.
✔️ Used Vagrant boxes to automatically spin up and provision VMs.
✔️ Managed VMs via Git Bash using SSH.
✔️ Practiced using commands like
vagrant init,vagrant up,vagrant halt,vagrant destroy.
⚠️ Common Errors & Solutions:
| ❌ Error | 💡 Solution |
vagrant: command not found | Run choco install vagrant, restart Git Bash, and ensure it's in your PATH. |
| Vagrant can't find VirtualBox | Ensure VirtualBox is properly installed and added to system environment variables. |
| SSH permission denied | Delete the .vagrant directory in your project and try vagrant up again. |
| VM not booting properly | Check RAM & storage allocation; use the right ISO file or Vagrant box. |
| Git Bash can't run Vagrant | Use Git Bash as Admin, and ensure Chocolatey, Vagrant, and VirtualBox are in the PATH. |
🎯 Biggest Takeaway:
DevOps isn't just about tools — it's about automating everything. Manual setup teaches the “how,” automation teaches the “why.”
