Initial Server Setup

Complete the initial server configuration steps to prepare your Ubuntu server for ORISO Platform v3.0.0 deployment on Kubernetes with Helm charts.
1

Connect to Server

Establish SSH connection to your Ubuntu server.
# Connect via SSH
ssh root@YOUR_SERVER_IP

# Or with specific user
ssh username@YOUR_SERVER_IP
Verify you can successfully SSH into the server before proceeding.
2

Update System

Update package lists and install essential tools required for the deployment.
# Update package lists
sudo apt update

# Upgrade all packages
sudo apt upgrade -y

# Install essential tools
sudo apt install -y \
    curl \
    wget \
    git \
    vim \
    nano \
    htop \
    net-tools \
    ca-certificates \
    gnupg \
    lsb-release \
    software-properties-common \
    apt-transport-https \
    jq

# Check system info
uname -a
lsb_release -a
Verify installation by checking versions: curl --version, git --version, jq --version
3

Create Non-Root User

Create a non-root user with sudo privileges for better security practices.
Only perform this step if you’re currently logged in as root.
# Create user (if you're root)
adduser caritas

# Add to sudo group
usermod -aG sudo caritas

# Switch to user
su - caritas

# Or logout and login as new user
Ensure you can still access the server after switching users, especially if SSH root login is disabled.
4

Configure Hostname

Set a descriptive hostname for your server to make identification easier.
# Set hostname
sudo hostnamectl set-hostname oriso-platform

# Verify
hostnamectl
The hostname should display as oriso-platform in the output.
5

Configure Timezone

Set the correct timezone for your server location.
# Set timezone (example: Europe/Berlin)
sudo timedatectl set-timezone Europe/Berlin

# Or use interactive selector
sudo dpkg-reconfigure tzdata

# Verify
timedatectl
Replace Europe/Berlin with your appropriate timezone. Use timedatectl list-timezones to see all available timezones.
6

Disable Swap

Disable swap memory as Kubernetes (k3s) requires swap to be disabled.
# Disable swap
sudo swapoff -a

# Remove swap from fstab (permanent)
sudo sed -i '/ swap / s/^\(.*\)$/#\1/g' /etc/fstab

# Verify
free -h
Swap should show 0 in the free -h output.
This permanently disables swap. Ensure your server has sufficient RAM for all services.

​
Verification

After completing all steps, verify your server is ready: 
# Check system information
hostnamectl
timedatectl
free -h

# Verify swap is disabled
free -h | grep Swap
# Should show: Swap:             0           0           0
