从Docker官方教程创建MongoDB图像错误

Question

这里是the official tutorial创建mongoDB img。

我严格遵循教程，并生成以下Dockerfile

# https://docs.docker.com/engine/examples/mongodb/#creating-a-dockerfile-for-mongodb 
# Dockerizing MongoDB: Dockerfile for building MongoDB images 
# Based on ubuntu:latest, installs MongoDB following the instructions from: 
# http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/ 

# Format: FROM repository[:version] 
FROM  ubuntu:latest 

# Installation: 
# Import MongoDB public GPG key AND create a MongoDB list file 
RUN apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927 
RUN apt-get install -y --no-install-recommends software-properties-common 
RUN echo "deb http://repo.mongodb.org/apt/ubuntu $(cat /etc/lsb-release | grep DISTRIB_CODENAME | cut -d= -f2)/mongodb-org/3.2 multiverse" | tee /etc/apt/sources.list.d/mongodb-org-3.2.list 


# Update apt-get sources AND install MongoDB 
RUN apt-get update && apt-get install -y mongodb-org 

# MongoDB requires a data directory. Let’s create it as the final step of our installation instructions. 
# Create the MongoDB data directory 
RUN mkdir -p /data/db 

# Expose port 27017 from the container to the host 
EXPOSE 27017 

# Set usr/bin/mongod as the dockerized entry-point application 
ENTRYPOINT ["/usr/bin/mongod"] 

但是，当我执行

$ docker build --tag my/repo . 

我得到了以下错误：

这是怎么回事上？为什么失败？如何解决它？

编辑：

调整命令命令后，我最终的脚本是这样的：

# Format: FROM repository[:version] 
FROM  ubuntu:latest 


# Update apt-get sources AND install MongoDB 
RUN apt-get update 

# Installation: 
# Import MongoDB public GPG key AND create a MongoDB list file 
RUN apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927 
RUN apt-get install -y --no-install-recommends software-properties-common 
# RUN echo "deb http://repo.mongodb.org/apt/ubuntu $(cat /etc/lsb-release | grep DISTRIB_CODENAME | cut -d= -f2)/mongodb-org/3.2 multiverse" | tee /etc/apt/sources.list.d/mongodb-org-3.2.list 
RUN echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list 

RUN apt-get install -y mongodb-org 

# MongoDB requires a data directory. Let’s create it as the final step of our installation instructions. 
# Create the MongoDB data directory 
RUN mkdir -p /data/db 

# Expose port 27017 from the container to the host 
EXPOSE 27017 

# Set usr/bin/mongod as the dockerized entry-point application 
ENTRYPOINT ["/usr/bin/mongod"] 

然后我得到了以下错误：

下一步，然后我补充说：“RUN APT-得到安装sudo“，然后我得到以下错误：

3击倒，我不确定这整件事情会奏效。这是我最后的Dockerfile。

# https://docs.docker.com/engine/examples/mongodb/#creating-a-dockerfile-for-mongodb 
    # Dockerizing MongoDB: Dockerfile for building MongoDB images 
    # Based on ubuntu:latest, installs MongoDB following the instructions from: 
    # http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/ 

# Format: FROM repository[:version] 
FROM  ubuntu:latest 


# Update apt-get sources AND install MongoDB 
RUN apt-get update 

# Installation: 
# Import MongoDB public GPG key AND create a MongoDB list file 
RUN apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927 
RUN apt-get install -y --no-install-recommends software-properties-common 

RUN apt-get install sudo 

# RUN echo "deb http://repo.mongodb.org/apt/ubuntu $(cat /etc/lsb-release | grep DISTRIB_CODENAME | cut -d= -f2)/mongodb-org/3.2 multiverse" | tee /etc/apt/sources.list.d/mongodb-org-3.2.list 
RUN echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list 

RUN apt-get install -y mongodb-org 

# MongoDB requires a data directory. Let’s create it as the final step of our installation instructions. 
# Create the MongoDB data directory 
RUN mkdir -p /data/db 

# Expose port 27017 from the container to the host 
EXPOSE 27017 

# Set usr/bin/mongod as the dockerized entry-point application 
ENTRYPOINT ["/usr/bin/mongod"] 

如果你能使它工作，请粘贴你的Dockerfile，我很想知道我的脚本中有什么问题。我跟着教程，它不起作用。

快速谷歌搜索您发现的确切错误消息this。

这是apt的错误，表示无法在其存储库中找到software-properties-common软件包。当找到包更改时，通常意味着需要更新。

您正在运行apt-get update但您正在运行之后的更新行。

RUN apt-get install -y --no-install-recommends software-properties-common 
... 
RUN apt-get update && apt-get install -y mongodb-org 

相反，运行第一

RUN apt-get update 
RUN apt-get install -y --no-install-recommends software-properties-common 
... 
RUN apt-get install -y mongodb-org 

更新：您的更新安装说MongoDB的包，当你现在得到一个错误。这是因为您已经加载了一个deb程序包文件，并且需要再次更新apt以便它知道它。在这一点上，最简单的事情只是在任何apt-get命令的前面，它们抱怨没有找到包含update的包。

RUN apt-get update && apt-get install -y --no-install-recommends software-properties-common 
... 
RUN apt-get update && apt-get install -y mongodb-org
