Nodejs安装在Docker上

Question

我正在尝试在Docker上运行我的应用程序。我正在使用的库之一是https://www.npmjs.com/package/odbc。为了安装该lib，我需要满足ODBC读数中描述的要求：

• UnixODBC二进制文件和模块编译的开发库
  • 在Ubuntu/debian sudo apt-get安装unixodbc unixoDBC-dev
  • 在redhat/centos sudo yum安装unixodbc unixoDBC-Devel
• 目标数据库的ODBC驱动程序
• 正确配置了odbc.ini和odbcinst.ini。

根据Microsoft Doc，以安装SQL Server 13-for-sql-server？view = sql-server-2017＃ubuntu-1604-1我设法在Mac上安装了本地的所有内容，并在Azure上成功连接了SQL Server，但仍存在将它们安装在Docker上，然后在VST上运行的问题。我的dockerfile：

FROM ubuntu:16.04
USER root
RUN apt-get update
RUN apt-get install --yes curl
RUN curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
RUN apt-get install --yes nodejs
RUN apt-get install --yes build-essential
RUN apt-get install -y npm 
RUN curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add -
RUN curl https://packages.microsoft.com/config/ubuntu/16.04/prod.list > /etc/apt/sources.list.d/mssql-release.list
RUN apt-get install -y build-essential
RUN apt-get install -y make
RUN apt-get install apt-transport-https
RUN apt-get update && ACCEPT_EULA=Y apt-get install -y msodbcsql unixodbc-dev
ADD . /var/www/app
WORKDIR /var/www/app
RUN npm install && 
    npm cache clean --force
RUN npm run build 
EXPOSE 3000:80
CMD ["npm", "start"]

，但到目前为止，与

一致安装nodejs有问题

RUN curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -

错误：/bin/sh: 1: sudo: not found我试图仅安装驱动程序和安装nodejs，只使用一些现有的docker images：

FROM ubuntu:16.04
USER root
RUN apt-get update
RUN apt-get install --yes curl
RUN curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add -
RUN curl https://packages.microsoft.com/config/ubuntu/16.04/prod.list > /etc/apt/sources.list.d/mssql-release.list
RUN apt-get install -y build-essential
RUN apt-get install -y make
RUN apt-get install apt-transport-https
RUN apt-get update && ACCEPT_EULA=Y apt-get install -y msodbcsql unixodbc-dev
FROM node:9-alpine
ADD . /var/www/app
WORKDIR /var/www/app
RUN npm install && 
    npm cache clean --force
RUN npm run build 
EXPOSE 3000:80

但是该方法引发了一个错误：

Answer 1

您正在从ubuntu:16.04映像上进行工作，从本质上讲，Nodejs家伙已经完成了很多步法。

如果我是你，我会去看image node:10-stretch-slim。然后使用apt-get安装所需的驱动程序（如果有的话，否则脚本下载并安装在您的Dockerfile中）。

sudo命令通常不安装在Docker映像上，因为在容器会话中默认情况下用户为root。如果您看到有关sudo的任何错误，通常可以从引起问题的命令行中删除sudo。

可能的解决方案

在此处更新我的答案，并为您提供一个可能的解决方案。

此解决方案将根据Debian Stretch 9将您的应用程序放在节点10映像中。它将从Debian 9 Microsoft存储库中为您提供数据库驱动程序，并安装我从您的那里看到的所有包装问题。

我还在脚本的底部添加了ENTRYPOINT和CMD。但是这些行是猜测的，因为您的问题尚未指出您如何实际启动应用程序。（如果您添加了，那么我将更新我的答案）。

注意。请注意，我将--host 0.0.0.0传递给npm run start命令。这是为了避免将实时服务器绑定到Localhost，这将使容器外部无法访问。除非您使用--network="host"启动容器。

您可能有另一种启动应用程序比实时开发服务器更"生产等级"的方法。如果是这样，只需更换Dockerfile底部的线，或在此答案上问我。

Dockerfile

# from debian stretch 9.8, node 10
FROM node:10-stretch-slim
# get apt-transport-https, etc., so that we can install by https protocol
RUN apt-get update 
 && apt-get install -y 
      apt-transport-https 
      build-essential 
      make
# add and accept the microsoft signature
RUN curl -q https://packages.microsoft.com/keys/microsoft.asc | apt-key add -
# retrieve the microsoft packagelist for debian 9
RUN curl -q https://packages.microsoft.com/config/debian/9/prod.list > /etc/apt/sources.list.d/mssql-release.list
# install the ms odbc sql driver and unixodbc header stuff
RUN apt-get update 
 && ACCEPT_EULA=Y apt-get install -y 
      msodbcsql17 
      unixodbc-dev 
 && rm -rf /var/lib/apt/lists
# expose port 80 in containers of this image
EXPOSE 80
# copy working directory into the image and set as pwd
ADD . /var/www/app
WORKDIR /var/www/app
# install dependencies for the application
RUN npm install 
 && npm cache clean --force
# build the application
RUN npm run build
# i am just guessing how you want your app started here, npm?
ENTRYPOINT ["npm"]
# and then this, which makes "npm run start --host 0.0.0.0"
CMD ["run", "start", "--host", "0.0.0.0"]

用：

构建图像

docker build -t mynodeapp:0.1 .

使用：

运行应用程序图像

docker run -p 3000:80 --name mynodeapp mynodeapp:01

最终访问：http：//localhost：3000看到它工作。
