使用ubuntu的火鸟:最新的码头形象
使用ubuntu的火鸟:最新的码头形象
提问于 2020-08-01 14:20:31
我试图在Ubuntu中设置一个Gunicorn服务器:最新的Docker映像。
在Docker上启动时，我有以下输出
[2020-08-01 14:12:38 +0000] [6] [INFO] Starting gunicorn 20.0.4
[2020-08-01 14:12:38 +0000] [6] [DEBUG] Arbiter booted
[2020-08-01 14:12:38 +0000] [6] [INFO] Listening at: http://0.0.0.0:5000 (6)
[2020-08-01 14:12:38 +0000] [6] [INFO] Using worker: sync
[2020-08-01 14:12:38 +0000] [8] [INFO] Booting worker with pid: 8
[2020-08-01 14:12:38 +0000] [6] [DEBUG] 1 workers在那之后，我看不到终端上的任何输出。我用电脑上打开的sudo netstat -tunlp检查了端口，Gunicorn没有运行。
如果我在虚拟主机中使用相同的gunicorn --bind 0.0.0.0:5000 app:app --log-level debug设置，它会很好.我错过了什么吗？

我设法使它在本地开发上工作。下面的Dockerfile包含所有修改，我对命令进行了注释，以使其正常工作。

从曝露指令的坞文档中：
公开指令实际上并不发布端口。它作为构建映像的人和运行容器的人之间的一种文档类型，而这些港口将被发布。要在运行容器时实际发布端口，请在运行的码头上使用-p标志发布和映射一个或多个端口，或者使用-P标志发布所有公开的端口，并将它们映射到高级端口。
因此，由于gunicorn正在监听端口500，所以您需要这样运行您的容器：
docker run -p 5000:5000 your_image传递您在运行容器时已经传递的任何其他选项。
