docker 部署Django遇到了问题。。

Question

我使用conda管理python开发环境
按照这里的教程：https://www.qcloud.com/commun...
各种错误，请问用conda管理的Django程序怎么部署到docker的？

详细信息如下：
分为三个镜像，mysql,nginx,web(uwsgi+Django).

目录结构：

mysql->start.sh 内容如下:

#!/bin/bash 
#

echo "---------------start mysql image-------------------"
docker run --name mysql \
-v $(pwd)/conf.d:/etc/mysql/conf.d \
-v $(pwd)/data:/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=123456 \
-p 3307:3306 \
-d daocloud.io/mysql:5.6.30 \
--character-set-server=utf8 --collation-server=utf8_unicode_ci
sleep 15

nginx->nginx-conf->backend_nginx.conf 内容如下:

user www-data;
worker_processes auto;
pid /run/nginx.pid;

nginx->Dockerfile 内容如下:

FROM daocloud.io/nginx

RUN rm /etc/nginx/conf.d/default.conf
ADD nginx-conf/ /etc/nginx/conf.d/

nginx->start.sh 内容如下:

docker run --name nginx-server \
--link django:web \
-v /www/static \
--volumes-from django \
-p 8888:80 \

sleep 15

web->Dockerfile 内容如下:

# 基础镜像

RUN apt-get update && apt-get install -y curl vim wget 

RUN pip install uwsgi -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com

ADD backend_uwsgi.ini /usr/src/backend/

RUN echo 'export PATH=/opt/conda/bin:$PATH' > /etc/profile.d/conda.sh && \
    wget --quiet http://repo.continuum.io/miniconda/Miniconda-latest-Linux-x86_64.sh && \

    rm ./Miniconda-latest-Linux-x86_64.sh

ENV PATH /opt/conda/bin:$PATH

ADD environment.yml /usr/src/backend/environment.yml

RUN conda env create -f /usr/src/backend/environment.yml

RUN source activate webback

web->start.sh 内容如下：

#!/bin/bash 
#
docker exec -d mysql mysql -uroot -p123456 -e "create database blog;"

运行 docker ps -a 查看结果是:

各种失败，怎么都不通，请大家帮帮我，顺便说，我是使用conda管理开发环境的，怎么把conda加到镜像里我始终都搞不通。

docker什么版本？先试试 docker service restart 再不行就升级docker
