How to install Docker on Ubuntu 22.04?

Question

Installing Docker on a fresh Ubuntu 22.04 server comes down to two routes: the convenience script at get.docker.com, or adding Docker's apt repository by hand.

They differ in what they pin and what they leave you to maintain afterwards. Either way there are post-installation steps that decide whether the daemon is usable without sudo.

**For a development machine, Docker's convenience script is quickest (Docker does not recommend it for production):**

```bash
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh
```

Then, to avoid sudo, add your user to the docker group. Docker warns that this group grants root-level privileges to the user; rootless mode avoids that:

```bash
sudo usermod -aG docker $USER
newgrp docker
```

Verify with `docker --version` and `docker run hello-world`.

For a production server, use the apt repository method instead: by default the convenience script installs the latest release, which can bring unexpected major-version upgrades. Check our [Docker Guide](/guides/docker) for the full walkthrough.
