【问题描述】：

我试图使用 docker-compose 来启动 Airflow，我已经在我有 `docker-compose.yaml 的目录中使用了它。我没有更改 docker-compose.yaml，只是使用了 Apache Airflow 的标准版本。顺便说一句，我之前安装过Docker，并且使用过。这是控制台中的输出：

(base) ruslanpilipyuk@MacBook-Pro-Ruslan airflow-local % docker-compose -f docker-compose.yaml up -d

【解决方案1】：

似乎缺少气流用户定义。

尝试运行以下（一次），然后运行 docker-compose

echo -e "AIRFLOW_UID=$(id -u)" > .env

另请参阅：https://airflow.apache.org/docs/apache-airflow/stable/start/docker.html（初始化环境）

【解决方案2】：

在我的 Redhat 7.9 VM 上尝试“docker-compose up”时，我遇到了完全相同的错误。我们的 Unix 管理员正在帮助我撤消最近的一个服务器补丁，我认为该补丁可能会导致问题。他要求运行'docker version'。我做到了。它喷出了结果。最后一行读到： ==>“无法连接到 unix:///var/run/docker.sock 的 Docker 守护进程。docker 守护进程是否正在运行？” 嗬！然后，他使用“systemctl start docker”以 root 身份启动 docker 守护进程。我再次运行“docker-compose up”。
Docker 已启动并运行。
