Question

当我运行 docker-compose up 时，Docker 将运行以下四个容器。它们运行完全成功。

[+] Running 4/4
 ⠿ Container redis_1     Started                                                                             5.6s
 ⠿ Container postgres_1  Started                                                                             4.6s
 ⠿ Container celery_1    Started                                                                             8.2s
 ⠿ Container flask_1     Started                                                                            12.3s

但是，因为 flask_1 依赖于其他三个容器，所以它最后启动那个容器。

这样做的问题是在 flask_1 启动之前出现的前三个容器的初始控制台输出没有出现。

我看到的输出是

但是如果我手动检查其他容器之一的日志，例如 postgres_1。有很多输出没有显示。

如何让 docker 显示它正在跳过的初始输出？

Answer 1

我想我知道你想要什么。如果您想在控制台上看到更多输出，请使用 docker-compose --verbose up 但这不是查看 docker-compose 日志的最佳方式。因为如果会话结束，docker-compose 项目将关闭。使用 docker-compose --verbose up -d 在后台启动您的 docker-compose 项目，然后使用以下命令监控所有 docker-compose 项目：

docker-compose logs -f

希望能帮到你
