Omnicore Networks - Public Tools

Scripts we use internally at Omnicore Networks. You're welcome to use them too.

Everything here is free to use, fork, and modify. Pull requests probably won't get merged unless you've talked to a maintainer first. Reach out to alex (GitHub: @squishylemon).

Requirements

• Ubuntu Server (scripts are written for that)
• sudo or root access where noted
• A network connection for package downloads

Scripts

scripts/docker/setup-ubuntu-server.sh

Installs Docker Engine on Ubuntu Server from Docker's official apt repo.

What it does, step by step:

1. Checks you're on Ubuntu and running as root (or via sudo).
2. Removes old docker.io / docker-engine packages if they're installed.
3. Installs curl, ca-certificates, and gnupg.
4. Adds Docker's GPG key and apt source (skips if already there).
5. Installs docker-ce, the CLI, containerd, Buildx, and the Compose plugin.
6. Enables and starts the docker service.
7. Adds your sudo user to the docker group so you can run Docker without sudo (after re-login).
8. Runs docker run hello-world to confirm it works.

Run it:

curl -fsSL https://raw.githubusercontent.com/OpiumNetworks/public-tools/main/scripts/docker/setup-ubuntu-server.sh -o setup-docker.sh
chmod +x setup-docker.sh
sudo ./setup-docker.sh

Or clone the repo and run the script from your checkout:

git clone https://github.com/OpiumNetworks/public-tools.git
cd public-tools
sudo bash scripts/docker/setup-ubuntu-server.sh

After install: log out and back in (or reboot) if you were added to the docker group. Then try:

docker ps
docker compose version

Tested on Ubuntu 22.04 and 24.04 LTS.
