How to create docker image with nodejs 12, java, gcc, g++,python3, monocs

问题

  1. 我正在尝试将我的Node.js和Express API容器化。在我的API中，我使用了https://www.npmjs.com/package/compile-run 包来编译和运行C、Cpp、Java、JavaScript（Node.js环境）和Python语言。
  2. 这个包需要服务器上安装有这5种编译器（gcc、g++、nodejs、python3、javac）。如果缺少任何一个编译器，它都会抛出错误。
  4. 在我的本地环境（非容器化）中，在Windows和Ubuntu上都能正常工作（因为我在它们上面安装了编译器）。
  6. 我正试图在我的Docker镜像中复制同样的环境。但是我卡住了。
  8. 看看我的
  9. **Dockerfile**：
  11.     FROM node:12
  12.     WORKDIR /app
  13.     COPY package.json /app
  14.     RUN npm install
  15.     COPY . /app
  16.     CMD ["npm","start"]
  18. 我认为 node-12 镜像自带了 gcc、g++、python3 和 nodejs（当然）。
  19. 但问题在于 **Java**。我无法编译Java代码。
  21. 所以我尝试了这种方式：
  23.     FROM node:12
  24.     RUN apt-get -y install default-jre
  25.     # RUN java -version
  26.     RUN apt -y install default-jre
  27.     RUN apt install openjdk-11-jre-headless
  28.     RUN java -version
  29.     
  30.     WORKDIR /app
  31.     
  32.     COPY package.json /app
  33.     RUN npm install
  34.     COPY . /app
  35.     CMD ["npm","start"]
  37. 但我无法使用 apt/apt-get 安装 open-jdk 或 open-jre。
  38. 配置Docker的正确方法是什么？
  40. 这是我的Node.js API存储库：https://github.com/yogendramaarisetty/online-compiler-api
英文:

I am trying to dockerize my NodeJs & Express API . In my API iam using https://www.npmjs.com/package/compile-run package to compile and run C,
Cpp,Java,JavaScript(Node.js env), Python languages.
This package requires all 5 compilers(gcc,g++,nodejs,python3,javac) installed on the server. If any compiler misses, it throws error.

In my local(undockerized) the API is working completely fine on both windows & ubuntu(As I have installed compilers on them).

I am trying to replicate the same on my docker image. But I am stuck.

Look at my
Dockerfile:

  1. FROM node:12
  2. WORKDIR /app
  3. COPY package.json /app
  4. RUN npm install
  5. COPY . /app
  6. CMD ["npm","start"]

I think node-12 image comes along with gcc, g++,python3 and nodejs(obviously).
But the issue is with java. I am not able to compile java code.

so I tried it this way

  1. FROM node:12
  2. RUN apt-get -y install default-jre
  3. # RUN java -version
  4. RUN apt -y install default-jre
  5. RUN apt install openjdk-11-jre-headless
  6. RUN java -version
  8. WORKDIR /app
  11. COPY package.json /app
  12. RUN npm install
  13. COPY . /app
  14. CMD ["npm","start"]

But I am not able to install open-jdk or open-jre with apt/apt-get.
What is the right way to configure docker?

得分: 7

首先，您必须使用 apt-get update 命令更新软件包列表，然后可以安装 openjdk-8。该发行版不支持 openjdk-11。我使用了 docker run -it node:12 /bin/bash 命令来查看可用的内容，

  1. FROM node:12
  2. RUN apt-get update && apt-get install -y openjdk-8-jdk

例如，

  1. $ cat Dockerfile
  2. FROM node:12
  3. RUN apt-get update && apt-get install -y openjdk-8-jdk
  4. $ docker build --tag mynode:1.0 .
  5. $ docker run -it mynode:1.0 /bin/bash
  6. root@d70858199dd1:/# java -version
  7. openjdk version "1.8.0_265"
  8. OpenJDK Runtime Environment (build 1.8.0_265-8u265-b01-0+deb9u1-b01)
  9. OpenJDK 64-Bit Server VM (build 25.265-b01, mixed mode)
  10. root@d70858199dd1:/# javac -version
  11. javac 1.8.0_265
  12. root@d70858199dd1:/#

如果确实需要 Java 11，有多种方式和位置可以获取 openjdk-11。其中一个是 bell-sw。例如，

  1. $ cat Dockerfile
  2. FROM node:12
  3. RUN apt-get update && apt-get install -y libasound2 libxtst6
  4. RUN wget https://download.bell-sw.com/java/11.0.7+10/bellsoft-jdk11.0.7+10-linux-amd64.deb && \
  5.     apt install ./bellsoft-jdk11.0.7+10-linux-amd64.deb
  6. $ docker build --tag mynode:1.1 .
  7. $ docker run -it mynode:1.1 /bin/bash
  8. root@37771ce98727:/# java -version
  9. openjdk version "11.0.7" 2020-04-14 LTS
  10. OpenJDK Runtime Environment (build 11.0.7+10-LTS)
  11. OpenJDK 64-Bit Server VM (build 11.0.7+10-LTS, mixed mode)
  12. root@37771ce98727:/# javac -version
  13. javac 11.0.7

如果您确实需要 Java 11，有多种方式和地方可以获取 openjdk-11，其中一个是 bell-sw。例如，

英文:

First you must update the package list with apt-get update, then you can install openjdk-8. openjdk-11 isn't available with that distribution of node. I used docker run -it node:12 /bin/bash to see what there was,

  1. FROM node:12
  2. RUN apt-get update && apt-get install -y openjdk-8-jdk

For example,

  1. $ cat Dockerfile                                         
  2. FROM node:12
  3. RUN apt-get update && apt-get install -y openjdk-8-jdk
  4. $ docker build --tag mynode:1.0 .
  5. $ docker run -it mynode:1.0 /bin/bash                                    
  6. root@d70858199dd1:/# java -version
  7. openjdk version "1.8.0_265"
  8. OpenJDK Runtime Environment (build 1.8.0_265-8u265-b01-0+deb9u1-b01)
  9. OpenJDK 64-Bit Server VM (build 25.265-b01, mixed mode)
  10. root@d70858199dd1:/# javac -version
  11. javac 1.8.0_265
  12. root@d70858199dd1:/#

If you really do need Java 11, there are multiple ways and places to get openjdk-11. One is bell-sw. For example,

  1. $ cat Dockerfile
  2. FROM node:12
  3. RUN apt-get update && apt-get install -y libasound2 libxtst6
  4. RUN wget https://download.bell-sw.com/java/11.0.7+10/bellsoft-jdk11.0.7+10-linux-amd64.deb && \
  5. 	apt install ./bellsoft-jdk11.0.7+10-linux-amd64.deb
  6. $ docker build --tag mynode:1.1 .
  7. $ docker run -it mynode:1.1 /bin/bash
  8. root@37771ce98727:/# java -version
  9. openjdk version "11.0.7" 2020-04-14 LTS
  10. OpenJDK Runtime Environment (build 11.0.7+10-LTS)
  11. OpenJDK 64-Bit Server VM (build 11.0.7+10-LTS, mixed mode)
  12. root@37771ce98727:/# javac -version
  13. javac 11.0.7
