The Ultimate DevOps Sandbox .
“Tired of juggling multiple VMs for your DevOps stack? Get it all in one place with the ultimate DevOps VM—just one command, zero hassle.”
Intro
This idea’s been chilling in my mind for ages while I was playing around with Vagrant. I’ve lost count of the number of cool builds I’ve tried out from GitHub across different stacks. But, you know the deal—too many VMs, and suddenly your laptop sounds like a jet taking off. The kicker? A lot of these VMs are pretty much the same, with just slight differences in configurations.The Idea Behind the Bundle
One day, it hit me: Why not just use one VM and throw everything into it? One box, all the tools. No more hogging resources, and you still get to have all your DevOps toys in one place. That’s how the All-In-One DevOps VM idea was born—“A single VM to rule them all“, loaded with everything you need for your DevOps shenanigans.
Just run a single “vagrant up" command, and you’re good to go!
GitHub Repository
Check out the first release on my GitHub repo. Feedback & contributions are welcome, Let’s see how it grows with your help!What’s in the pack
Here’s what you’ll find packed into this VM:- KVM + kcli (virtualization CLI wrapper)
- Ansible AWX (will soon be replace by OLAM)
- HashiCorp Squad:
- Docker
- Kubernetes (single-node 1.28)
- Helm + Kubernetes Dashboard
- k9s for managing your K8s like a boss
- kubectl autocompletion
- kubescape
- And more…
- Compliance as Code:
- Jenkins
- Cloud Shell CLI for OCI, AWS, Azure, and GCP
- Other handy tools like
tmate,bind-utils, and a bunch more!
Get Started
Pre-Reqs
Resources: Recommended range is:- RAM: 4–8GB
- vCPU: 2–4 cores
vb.memory and vb.cpus settings to match your machine’s capacity.
How to Roll:
- Clone or Download the Repo:
$ git clone https://github.com/brokedba/Devops_all_in_one_vm.git - Hop into the Directory and fire up the VM:
$ cd /path/to/Devops_all_in_one_vm/OL7 $ vagrant up
Explore The Box
KVM
- Display current setup
[root@localhost ~]# kcli list pool +---------+------------------+ | Pool | Path | +---------+-------------------+ | default | /u01/guest_images | +---------+-------------------+ [root@localhost ~]# kcli list network Listing Networks... +---------+--------+------------------+------+---------+------+ | Network | Type | Cidr | Dhcp | Domain | Mode | +---------+--------+------------------+------+---------+------+ | default | routed | 192.168.122.0/24 | True | default | nat | +---------+--------+------------------+------+---------+------+
TERRAFORM (KVM)
In this example we will be using libvirt terraform provider to launch a KVM VM inside our vm (nested virtualization)
- Download the provider
[root@localhost]# wget https://github.com/dmacvicar/terraform-provider-libvirt/releases/download/v0.6.2/terraform-provider-libvirt-0.6.2+git.1585292411.8cbe9ad0.Fedora_28.x86_64.tar.gz [root@localhost]# tar xvf terraform-provider-libvirt-**.tar.gz
- Add the plugin in a local registry and install the provider
[root@localhost]# mkdir –p ~/.local/share/terraform/plugins/registry.terraform.io/dmacvicar/libvirt/0.6.2/linux_amd64
[root@localhost]# mv terraform-provider-libvirt ~/.local/share/terraform/plugins/registry.terraform.io/dmacvicar/libvirt/0.6.2/linux_amd6- Add the below code block to the main.tf file to map libvirt references with the actual provider
[root@localhost projects]# cd /root/projects/terraform [root@localhost]# vi libvirt.tf ... terraform { required_version = ">= 0.13" required_providers { libvirt = { source = "dmacvicar/libvirt" version = "0.6.2" } } } ... REST of the ConfigRun :
terraform init & terraform plan
