The xyz.sh wrapper adds no telemetry and does not perform hidden actions. You can read the full source on the page or with curl -fsSL xyz.sh/ .sh before running it. Piping a remote script to bash is still a risk — review the source first. The step that follows is Docker's official convenience script. Docker itself does not recommend relying on it in production; see https://docs.docker.com/engine/install/.

Which operating systems are supported?

Declared support: Debian, Ubuntu, CentOS, Rocky Linux, and AlmaLinux. The script detects the distribution and asks before continuing on an unrecognized OS. Syntax was checked with bash -n and ShellCheck; installer scripts have not been end-to-end verified on every listed distribution.

Yes. Run it as root or via sudo bash. The script exits with a message if it is not root.

How do I uninstall it?

This wrapper has no uninstall command. Follow Docker's official docs, remove packages such as docker-ce with your package manager, and handle the repository yourself.

Will it add my user to the docker group?

Not automatically. If you ran it with sudo and SUDO_USER is not root, the script asks whether to add that user to the docker group. A new login is required for the group to take effect.

Install Docker Tutorial (Official Script on Debian, Ubuntu, CentOS)

This tutorial shows how to install Docker Engine on a Linux VPS with xyz.sh/docker. The install is performed by the official get.docker.com script; xyz.sh only previews and confirms it.

Prerequisites

You need a VPS running Debian, Ubuntu, CentOS, Rocky, or AlmaLinux, and root access.

Docker does not recommend relying on the convenience script in production. For a manual, distro-specific install, see https://docs.docker.com/engine/install/.

Steps

Optional: review the source with curl -fsSL xyz.sh/docker.sh, or open the script page in a browser.

As root, run: curl -fsSL xyz.sh/docker | bash

The wrapper downloads the official installer, prints the first 20 lines and a SHA256, then runs it only after confirmation. Use bash -s -- --dry-run to preview official steps, or --mirror Aliyun for a mirror the official script supports.

If you used sudo, you are asked whether to add SUDO_USER to the docker group; it is not automatic. A new login is required afterwards.

How to verify

After install, run docker --version. Optionally run docker run --rm hello-world (this pulls Docker's official test image).

How to uninstall

This wrapper has no uninstall command. To remove Docker Engine, follow Docker's official documentation and use your distro's package manager to remove docker-ce and related packages. Decide separately whether to delete the repository the official script added.
