Question

我正在尝试使用docker文件挂载文件夹，而不是在构建时复制它。我们使用git进行开发，并且我不希望每次更改测试时都重建映像。

我的docker文件现在就是这样

#set base image
FROM centos:centos7.2.1511

MAINTAINER Alex <alex@app.com>

#install yum dependencies
RUN yum -y update \\
&&  yum -y install yum-plugin-ovl \
&&  yum -y install epel-release \
&&  yum -y install net-tools \
&&  yum -y install gcc \
&&  yum -y install python-devel \
&&  yum -y install git \
&&  yum -y install python-pip \
&&  yum -y install openldap-devel \
&&  yum -y install gcc gcc-c++ kernel-devel \
&&  yum -y install libxslt-devel libffi-devel openssl-devel \
&&  yum -y install libevent-devel \
&&  yum -y install openldap-devel \
&&  yum -y install net-snmp-devel \
&&  yum -y install mysql-devel \
&&  yum -y install python-dateutil \
&&  yum -y install python-pip \
&&  pip install --upgrade pip

# Create the DIR
#RUN mkdir -p /var/www/itapp

# Set the working directory 
#WORKDIR /var/www/itapp

# Copy the app directory contents into the container 
#ADD . /var/www/itapp

# Install any needed packages specified in requirements.txt
#RUN pip install -r requirements.txt

# Make port available to the world outside this container
EXPOSE 8000

# Define environment variable
ENV NAME itapp

# Run server when the container launches
CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"]

我已经注释掉了itapp Django文件的创建和复制，因为我想安装它们，（我需要先重建它吗？）

然后我的安装命令是

docker run -it -v /Users/alex/itapp:/var/www/itapp itapp bash

我现在收到错误：

bash: warning: setlocale: LC_CTYPE: cannot change locale (en_US.UTF-8): No such file or directory
bash: warning: setlocale: LC_COLLATE: cannot change locale (en_US.UTF-8): No such file or directory
bash: warning: setlocale: LC_MESSAGES: cannot change locale (en_US.UTF-8): No such file or directory
bash: warning: setlocale: LC_NUMERIC: cannot change locale (en_US.UTF-8): No such file or directory
bash: warning: setlocale: LC_TIME: cannot change locale (en_US.UTF-8): No such file or directory

并且dev实例不会运行。

我如何将工作目录设置为我在运行时挂载的卷？

Answer 1

尝试此命令。 -w WORKDIR中的docker run选项设置容器内的工作目录。

docker run -d -v /Users/alex/itapp:/var/www/itapp -w /var/www/itapp itapp

此外，您还可以将容器端口映射到主机端口，以便能够访问，例如，从浏览器访问您的应用。

为此，请使用以下命令。

docker run -d -p 8000:8000 -v /Users/alex/itapp:/var/www/itapp -w /var/www/itapp itapp

在此之后，您的应用应该在localhost:8000

中运行
