查看特定的 Docker Compose 服务日志
使用 docker-compose up 时，我们可以在 YAML 文件中看到所有容器的日志； 然而，如果我们指定一个特定的容器服务，输出将不会在日志中显示任何服务依赖性。 因此，本文将探讨如何正确导出输出Docker Compose服务日志。
查看特定的 Docker Compose 服务日志
您可以以分离模式启动 Docker Compose，稍后将自己附加到所有容器的日志中。 然后，如果您完成了对日志跟踪的观察，您可以在不关闭服务的情况下从日志输出中分离出来。
请按照以下步骤完成此操作：
-
使用
docker-compose up -d使用 -d 选项以分离模式启动所有服务。 -
使用
docker-compose logs -t -f将自己附加到所有正在运行的服务的日志中。 -t 选项为我们提供时间戳，而 -f 参数表示我们在服务运行时跟踪日志输出。 - 使用 Ctrl+Z 或 Ctrl+C 将自己从日志输出中分离出来，而无需关闭正在运行的容器。
-
如果我们需要指定单个容器的日志，可以使用下面的命令：
$ docker-compose logs -t -f <service name> -
要将输出保存到文件中，我们可以使用
>>运算符将其添加到命令的末尾。$ docker-compose logs -t -f >> sample.log
使用 Docker Compose V2
从 Docker Compose 版本 2 开始，我们现在可以使用不带破折号 (-) 的 docker-compose。 我们还可以使用大多数 docker-compose 命令，也可以类似地调用它们而无需破折号：
$ docker compose logs -t -f --tail 3 sample-service test-service >> sample.log
