Docker-Install

A polished one-command Docker installer for fresh Ubuntu/Debian servers.

It installs:

• Docker Engine
• Docker CLI
• containerd
• Docker Buildx plugin
• Docker Compose plugin

It can also optionally add a chosen Linux user to the docker group so Docker commands can be run without sudo after the user logs out/in.

One-command install

Install Docker only:

curl -fsSL https://gitea.wheelytho.com/Wheelz/Docker-Install/raw/branch/main/install-docker.sh | bash

Install Docker and add the current SSH/login user to the docker group:

curl -fsSL https://gitea.wheelytho.com/Wheelz/Docker-Install/raw/branch/main/install-docker.sh | bash -s -- --current-user

Install Docker and add a specific user to the docker group:

curl -fsSL https://gitea.wheelytho.com/Wheelz/Docker-Install/raw/branch/main/install-docker.sh | bash -s -- --user obin

Non-interactive install without adding a docker user:

curl -fsSL https://gitea.wheelytho.com/Wheelz/Docker-Install/raw/branch/main/install-docker.sh | bash -s -- --yes

Local usage

git clone https://gitea.wheelytho.com/Wheelz/Docker-Install.git
cd Docker-Install
chmod +x install-docker.sh
./install-docker.sh --current-user

The old Docker-Install.sh filename still exists as a compatibility wrapper.

Options

--user USER        Add USER to the docker group after install.
--current-user     Add the invoking SSH/login user to the docker group.
--no-docker-user   Do not add anyone to the docker group.
-y, --yes          Non-interactive defaults. Skips docker group unless --user/--current-user is supplied.
-h, --help         Show help.

After adding a user to the docker group

Group membership does not apply to already-open shells. Log out and back in, or run:

newgrp docker

Then verify Docker works without sudo:

docker run --rm hello-world

Supported systems

• Ubuntu
• Debian

The installer uses Docker's official apt repository for the detected OS and codename.
