查看当前运行使用的 Docker

如果您在无根模式下使用 * * Docker * * ，那么正确的套接字通常位于您的用户目录中，而不是 “/var/run/Docker.sock”。让我们检查和修复您的设置。

1. Ensure Rootless Docker Is Running

Check if the rootless Docker daemon is running:

systemctl --user status docker

If it's not running, start it:

systemctl --user start docker

Enable it to start on boot:

systemctl --user enable docker

---

2. Use the Correct Socket for Rootless Docker

In rootless mode, Docker usually runs under:

$XDG_RUNTIME_DIR/docker.sock

Try:

docker -H unix://$XDG_RUNTIME_DIR/docker.sock version

If that works, permanently set it:

export DOCKER_HOST=unix://$XDG_RUNTIME_DIR/docker.sock

Or add this line to your ~/.bashrc or ~/.zshrc:

echo 'export DOCKER_HOST=unix://$XDG_RUNTIME_DIR/docker.sock' >> ~/.bashrc
source ~/.bashrc

---

3. Verify Your Docker Context

Run:

docker context ls

If it's set to the wrong socket, reset it:

docker context use rootless

Or manually create one:

docker context create rootless --docker "host=unix://$XDG_RUNTIME_DIR/docker.sock"
docker context use rootless

---

4. Restart Everything

systemctl --user restart docker

Then test:

docker version
docker info

---

5. If Issues Persist: Reinstall Rootless Docker

If you still get errors, reinstall the rootless Docker setup:

dockerd-rootless-setuptool.sh uninstall
dockerd-rootless-setuptool.sh install

Then restart and test again.

---

Summary

Start rootless Docker:

systemctl --user start docker

Use the correct socket:

export DOCKER_HOST=unix://$XDG_RUNTIME_DIR/docker.sock

Set the correct Docker context:

docker context use rootless
