Preperation

Every time I provision a new instance, there is always a checklist of things to prepare first, like running apt-get update and so on. This is especially true if the server needs Docker. I used to rely on AI to generate the installation script for me, since setting up Docker properly involves handling certificates rather than just a simple install command.

To save time, I finally wrote a basic setup script. It doesn't include server hardening, I prefer doing that manually. At its core, the script simply installs Docker, tree, and a few other essential tools I need. If a project requires more complex configurations like web servers or advanced security setups, I’d rather use Ansible instead of a bash script. So, this tool is specifically designed for standalone VMs, not orchestrated environments.

How to Run It

Before you run anything, here is a preview and the source code of my script. It is always wiser to check the code before executing it on your machine.

https://raw.githubusercontent.com/ilhamlii21/script-tools/main/basic-setup.sh 

#!/usr/bin/env bash
set -euo pipefail

# --- Cek root ---
if [[ $EUID -ne 0 ]]; then
  echo "Jalankan dengan sudo/root"; exit 1
fi

export DEBIAN_FRONTEND=noninteractive

echo "==> Update & upgrade sistem"
apt-get update -y
apt-get upgrade -y

echo "==> Install tools dasar"
apt-get install -y curl wget git vim htop net-tools unzip tree ca-certificates gnupg ufw

echo "==> Install Docker"
if ! command -v docker >/dev/null 2>&1; then
  curl -fsSL https://get.docker.com | sh
else
  echo "Docker sudah terpasang, dilewati"
fi

systemctl enable --now docker

# Tambahkan user yang menjalankan sudo ke grup docker
TARGET_USER="${SUDO_USER:-$USER}"
if [[ "$TARGET_USER" != "root" ]]; then
  usermod -aG docker "$TARGET_USER"
  echo "User $TARGET_USER ditambahkan ke grup docker (logout/login ulang)"
fi

echo "==> Selesai"
docker --version
docker compose version
tree --version

Execution Methods

1. Go Curl

curl -fsSL https://raw.githubusercontent.com/ilhamlii21/script-tools/main/basic-setup.sh | sudo bash

This command will run the basic-setup.sh script directly using sudo, so make sure your current user has root access.

2. Download first, then run

curl -fsSL https://raw.githubusercontent.com/ilhamlii21/script-tools/main/basic-setup.sh -o basic-setup.sh
less basic-setup.sh
sudo bash basic-setup.sh

This method downloads the script to your local storage first, allowing you to review its contents using the less command before executing it with root privileges (sudo). This is a much safer approach to ensure there are no suspicious commands hidden in the code before running it on your server.

This installation takes up approximately 800MB

before

ilham@vm:~$ df
Filesystem     1K-blocks    Used Available Use% Mounted on
/dev/root       29379712 1682988  27680340   6% /

after

ilham@vm:~$ df

/dev/root       29379712 2506104  26857224   9% /

Conclusion

Ultimately, this script is really just here to make my own life easier, haha I’m sure everyone has their own preferences and workflows when it comes to server setups.
