root@staging:~# sudo systemctl unmask docker
Removed /etc/systemd/system/docker.service.
root@staging:~# sudo systemctl start docker
Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xe" for details.
我需要運行它來解決 Docker 問題。在我運行 docker-compose up 1-2 小時後，Docker 不斷崩潰。所以我嘗試按照此處提供的步驟進行操作。
https://stackoverflow.com/questions/64163450/unable-to-docker-compose-up-any-project
當我運行這個時，我得到：
root@staging:~# start docker
Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xe" for details.
然後，透過執行 systemctl status docker.service 進行日誌記錄時：
