🐳 How to Completely Remove Docker from Your System

Whether you're troubleshooting, switching container engines, or simply freeing up space, uninstalling Docker from your system requires more than just a basic remove command. Here's a step-by-step guide to ensure Docker is completely removed from your system — along with all its components and data.

🔍 Why Remove Docker?

You might want to uninstall Docker if:

You're switching to another container platform (like Podman or containerd).
You're encountering persistent errors and want a clean slate.
You're no longer using containers and want to reclaim system space.

🧹 How to Remove Docker (Step-by-Step)

✅ For Ubuntu / Debian-based Systems

bashCopyEditsudo apt-get purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
sudo apt-get autoremove --purge -y
sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd

💡 This removes the Docker engine, CLI tools, plugins, and all container images, containers, volumes, and configuration files.

✅ For CentOS / RHEL-based Systems

bashCopyEditsudo yum remove docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd

🛠️ You might also want to clean up leftover config files in /etc/docker/.

✅ For Windows Users

Go to Settings → Apps → Installed Apps.
Search for Docker Desktop and click Uninstall.
Manually delete any leftover folders:
- C:\ProgramData\Docker
- C:\Users\<YourUsername>\.docker

✅ For macOS Users

Open Finder → Applications → Docker.app and drag it to the trash.
Open Terminal and run:

bashCopyEditrm -rf ~/.docker
sudo rm -rf /Library/Containers/com.docker.docker
sudo rm -rf /Library/Application\ Support/Docker\ Desktop
