启动 docker 撰写时出现错误"maximum recursion depth exceeded"

Question

我正在尝试为airflow v2旋转官方docker compose堆栈。

我唯一的改变是

a( 由于我使用RDS ，我已删除postgres服务

b( 已经相应地调整了CCD_ 2/CCD_。

这是文件

然而，当我试图运行任何docker-compose命令时，我会遇到这个非常神秘的错误，这是非常没有帮助的

$ docker-compose ps

我尝试过使用带引号和不带引号的rds连接字符串。

有人知道发生了什么事吗？

Answer 1

我在这里遇到了同样的错误，问题是缺少services密钥声明，在我的情况下，我意外地删除了它。只需将其添加回：

...
condition: service_healthy
services:
redis:
image: redis:latest
...
