Question

作为Docker run cannot find executable "uwsgi"的后续问题：

我已使用Dockerfile成功执行docker run和FROM python:2-onbuild # Set the working directory to /app WORKDIR /app # Copy the current directory contents into the container at /app ADD . /app # RUN pip install -r ./requirements.txt RUN pip install uwsgi EXPOSE 8000 CMD ["/usr/local/bin/uwsgi", "--http", " :8000" , "--wsgi-file", "falconapp.wsgi"]：

我知道自从我在终端上看到此输出后它正在运行：

dacao@Das-MacBook-Pro:~/Documents/bitbucket_2/heatmap_api$ docker ps 
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES

我确定Docker镜像正在运行：

http://127.0.0.1:8000/healthcheck 
http://localhost:8000/healthcheck 
http://host-ip:8000/healthcheck

接下来，我想检查一下我的应用是否真的在运行。我在我的safari浏览器上尝试了以下网址：

docker-machine ip

但都没有奏效。所有人都打不开页面＆＃39;错误。
如何访问我的应用程序？

对不起，我是新手，对船坞人来说真是个新手

更新：

我尝试了Error: No machine name(s) specified and no "default" machine exists并提供了docker ps。我不明白，因为我确定图片正在运行 - 我查看了docker-machine ls并查看了容器ID图片等。

我还尝试了NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS，它提供了空列表：docker-machine start

我应该在docker-machine create default Docker run ...之前按select user.id from user inner join computer on user.id=computer.user_id and computer.name='Macintosh' inner join component on computer.id=component.computer_id and component.componentName='ram' and component.componentValue = '16GB'或select user.id from user inner join computer on user.id=computer.user_id and computer.name='Macintosh' and computer.id not ( select component.computer_id from component where component.componentName='ram' and component.componentValue <> '16GB')创建一个泊坞机吗？

Answer 1

容器中的HTTP服务器正在端口8000上运行，因此如果要在主机上看到它，则必须使用以下模式发布端口：

docker run -p <host-port>:<container-port> smaller_runner

因此，如果要在端口8000上访问主机上的容器，则必须运行此命令：

docker run -p 8000:8000 smaller_runner

然后你可以查看其中一个网址：

http://127.0.0.1:8000/healthcheck
http://localhost:8000/healthcheck
http://host-ip:8000/healthcheck

如果你想在后台使用-dit运行容器：

docker run -dit --name test -p 8000:8000 smaller_runner

Answer 2

在查看启动日志时，看起来问题出在 uWSGI 配置上。

服务器似乎仅从127.0.0.1侦听，HOST是docker容器内的localhost。您是否尝试过在 uWSGI 配置中将0.0.0.0设置为{{1}}？并且不要忘记将端口绑定到主机。

如何在docker build和docker运行后访问我的falcon应用程序？
