运行Docker

标签: apache docker

这是我的Dockerfile:

# CentOs base image
FROM centos:centos6.8

# install python, pip, apache and other packages
RUN yum -y update; yum clean all
RUN yum -y install epel-release; yum clean all
RUN yum -y install centos-release-scl; yum clean all
RUN yum -y install python27; yum clean all
RUN yum -y install python-devel.x86_64; yum clean all
RUN yum -y install python-pip; yum clean all
RUN yum -y install gcc; yum clean all
RUN yum -y install httpd httpd-devel mod_ssl; yum clean all

# Make a non root user so I can run mod_wsgi without root
# USER adm

# install Python modules needed by the Python app
COPY requirements.txt /usr/src/app/
RUN pip install --no-cache-dir -r /usr/src/app/requirements.txt

# copy files required for the app to run
COPY . /usr/src/app/

# tell the port number the container should expose
EXPOSE 80

# run the application
# CMD ["mod_wsgi", "start-server run_apache_server.wsgi"]
# CMD ["cat", "/etc/passwd"]
# CMD ["cat", "/etc/group"]
# CMD ["find", "/"]
CMD ["/bin/sh", "-c", "/usr/bin/mod_wsgi-express start-server run_apache_server.wsgi --user adm --group apache"]

我可以运行该应用:

$ docker run -d -P --name myapp jacobirr/pleromatest

请参阅tcp端口80:

$ docker port myapp
80/tcp -> 0.0.0.0:32769

这是我的要求.txt:

Flask==0.10.1
Flask-Restless==0.13.1
Flask-SQLAlchemy==0.16
Jinja2==2.7
MarkupSafe==0.18
SQLAlchemy==0.8.2
Werkzeug==0.9.2
gunicorn==17.5
itsdangerous==0.22
mimerender==0.5.4
python-dateutil==2.1
python-mimeparse==0.1.4
requests==1.2.3
six==1.3.0
wsgiref==0.1.2
setuptools==5.4.2
mod_wsgi==4.5.15

为什么我无法在浏览器中访问localhost:32769?我怀疑这与:

有关

•运行apache的用户/组?

•我正在安装mod_wsgi这个事实,但它在码头工人身上没有任何地方"文件系统"所以我必须使用mod_wsgi-express

更新:

' 1' Netstat显示:

[root@9003b0d64916 app]# netstat -l

' 2' httpd似乎在我的容器中运行:

[root@9003b0d64916 mod_wsgi-localhost:8000:0]# ps aux | grep httpd

答案 0 :(得分:2)

从你的所有输出中,你的httpd / uwsgi进程肯定绑定到8000,这是你需要在容器上公开的端口。

netstat中的这一行显示8000的绑定,没有别的。

tcp        0      0 *:irdmi                     *:*                         LISTEN      

这里并不明显,但如果您使用--numeric-ports参数,则不会将8000转换为known port

在您的泊坞窗文件中,您应该再次

EXPOSE 8000

启动容器时,您还可以指定要在主机上使用的端口:

docker run -p 8080:8000 --name ...

在此之后,您应该可以使用浏览器点击

localhost:8080  ->  container:8000

将此添加到您的Dockerfile中,就在CMD之前:

WORKDIR  /usr/src/app/

假设您的start-apache-server文件位于该目录中。这将有助于wsgi找到所需的文件。
