• Automated bare metal installation with PXE boot or USB boot
• Automated Kubernetes installation and management with k3s
• Expose services to the Internet securely without static IP or port forwarding using Cloudflare Tunnel
• GitLab installation and many utilities
• Distributed block storage system with Longhorn
• Kubernetes cluster logging with Loki
• Registry as a pull through cache with Docker Registry
• Terraform HTTP backend and manage your environment on GitLab (see Terraform HTTP backend)
• Harbor installation for private Docker registry

Installation

curl https://raw.githubusercontent.com/qtvhao/picloud/main/pic -o pic && chmod +x pic

Or run with Docker (limited functions):

docker build -t pic https://github.com/qtvhao/picloud.git
docker run -it -v ~/.ssh/:/root/.ssh/ pic bash

docker run -it -v ~/.ssh/:/root/.ssh/ pic ./pic list-nodename $IDENTITY_FILE

Build then burn your ISO with FAI (Fully Automated Installation)

your_github_username="qtvhao" # this helps to get public key from your Github account, you can ssh to created machine without password
./pic fai "your_picloud" "$your_github_username"
./pic dd "$host_name" "/dev/sdc" # "disk dump" your ISO to USB device, or use PXE boot to install your machine (see below)

Automated bare metal installation with PXE boot

./pic pxe "8c:dc:d4:34:0c:f0" ./id_rsa "192.168.1.226"
# 
./pic auto-pxe $IDENTITY_FILE # this will automatically discover all machines in the same network and install them with created ISO above

Discover machines

PiCloud will automatically discover all machines which can be authenticated with given identity file. This is useful for managing a large number of machines.

./pic list-nodename ./id_rsa

List all machines in the same network and their IP addresses, includes product name and installed date.

Install/Reinstall Kubernetes cluster with k3s

The script will automatically install k3s-agent on the listed machines.

./pic reinstall-k3s "$IDENTITY_FILE"

Install recommended packages

Firstly, PiCloud will discover all machines with given identity file. Then, it will install k3s on all machines and setup a Kubernetes cluster. Finally, it will install all recommended packages on the master node. It also expose all services to the internet securely with Cloudflare Tunnel.

./pic recommended "$IDENTITY_FILE"
# This following steps will be executed/installed:
# - Install K3s
# - Redis
# - Gitlab
# - Grafana, Promtail and Loki
# - Longhorn storage

Setup Registry as a pull through cache (useful for air-gapped environment)

./pic Registry-as-a-pull-through-cache "$IDENTIFY_FILE" "$NODE_IP"
