Create Dockerfile, docker-compose.yml and run nodejs on windows10, Linux, Raspberry Pi

In the continuation of the following article I wrote earlier, I will create a Dockerfile and docker-compose.yml and describe the procedure to run it this time. https://qiita.com/MCYamamoto/items/4d424af9573fa90edf61

Final folder structure

First, the final folder structure. It will be as follows.

base folder
+docker-compose.yml
+cont
 +env
  +Dockerfile
   +deploy //Source code to be deployed(This time nodejs)
    +package.json
    +package-lock.json
    +build
     +js files
  +share //Shared folder for host and container

Create a Dockerfile

[Reference URL] https://qiita.com/pottava/items/452bf80e334bc1fee69a

For the overall flow, the above was referred to. Installation Make a note of the command while installing what you need to create the final Dockerfile.

1. Decide on a Docker image.

Since Raspberry Pi is ARM, I made it Debian as an image corresponding to ARM. [Reference URL] https://qiita.com/koduki/items/0ed303dac5d32646194f

2. Start the bash container.

$ sudo docker run -it -v $(pwd):/tmp/share debian:buster /bin/bash
 -it: Can be operated in the terminal
 -v: Folder sharing with containers

3. Install what you need.

Install the required packages depending on the program you want to run.

apt-get install package name

It's like that.

Please note that the "-y" option is required when writing to the Dockerfile because the installation will not be stopped.

In the end, I only needed node and sqlite, so it's better to make the container image a node, By leaving the process, the final result is as follows.

Here's what we're doing: --Copy the code to deploy --Install what you need on the OS --Install the required packages on the node under the deploy folder with "npm install"

#Dockerfile

FROM debian:buster

COPY deploy/ /home/deploy
WORKDIR /home/deploy

RUN apt-get update
RUN apt-get install -y cmake
RUN apt-get install -y libssl-dev
RUN apt install curl
RUN apt-get install -y sqlite3 libsqlite3-dev
RUN apt-get install -y nodejs npm && npm install n -g && n 12.18.4
RUN npm install

Create docker-compose.yml

Using the Dockerfile created earlier as a container image, the node under the deploy folder will be automatically started in the end.

version: "3.8"
services:
  cont:
    build:
      context: ./cont/env
      dockerfile: Dockerfile
    container_name: CONT-1
    tty: true
    volumes:
      - "./cont/env/share:/tmp/share"
      - ".:/workspace"
      - "./cont/env/deploy/build:/home/deploy/build"
    working_dir: /home/deploy/build
    command: npm run start

  "scripts": {
    "start": "node ./build/main.js",
  },

sudo docker-compose up --build
