A living collection of copy-paste installation guides (and scripts) for common DevOps tools on Ubuntu, CentOS, and Red Hat. I update this repo frequently—each guide is short, repeatable, and works on a clean VM.
- Connect_Remote_Machine — SSH setup, firewall ports, key auth
- Docker_Ubuntu — Docker Engine + Compose on Ubuntu
- Docker_Redhat — Docker (or Podman notes) on RHEL
- Jenkins_Ubuntu_CentOS — Jenkins LTS, service setup, plugins
- Minikube_Ubuntu — Minikube + kubectl + drivers on Ubuntu
- Minikube_CentOS — Minikube + kubectl on CentOS
📁 Each item is a single file with steps and/or an executable script. Open it to view commands; if it’s a script, you can run it directly (see below).
| Guide | Ubuntu | CentOS | Red Hat |
|---|---|---|---|
| Connect_Remote_Machine | ✅ | ✅ | ✅ |
| Docker_Ubuntu | ✅ | ❌ | ❌ |
| Docker_Redhat | ❌ | ❌ | ✅ |
| Jenkins_Ubuntu_CentOS | ✅ | ✅ | ❌ |
| Minikube_Ubuntu | ✅ | ❌ | ❌ |
| Minikube_CentOS | ❌ | ✅ | ❌ |
- Pick a file for your OS/tool (e.g.,
Docker_Ubuntu). - Open it and follow the commands line-by-line — or run the script if executable:
chmod +x Docker_Ubuntu
sudo ./Docker_Ubuntu- Reboot if the guide says so (e.g., after kernel/driver installs).
- Fresh VM or snapshot
sudoprivileges- Internet access + open firewall ports (SSH: 22, Jenkins: 8080, Docker registries, etc.)
Docker
docker --version && docker run --rm hello-worldJenkins
# Visit http://<host>:8080
# Unlock with the initial admin password:
cat /var/lib/jenkins/secrets/initialAdminPasswordMinikube
minikube start && kubectl get nodes- I update these guides regularly as package sources and best practices change.
- See something to improve? Issues/PRs are welcome.
- Keep steps idempotent and tested on a clean VM.
- Note OS version(s) verified (e.g., Ubuntu 22.04, CentOS 7/8, RHEL 9).
These scripts/steps are provided as-is. Run them on disposable VMs or after taking a snapshot. Always review commands before execution in production environments.
