node.js, domino-db & Docker

Here is an example to create a express application with the new domino-db npm module and run it in a docker container. Requirements are that node.js & Docker is installed. Everything is done in the command line and a text editor.

1. Install Express application generator

npm install express-generator -g

2. Create a fresh application with stylus engine

express -c stylus domino-express

3. Go to the newly created folder

cd domino-express/

4. Create a folder for the application

md app/

5. Copy all files to the app folder, only package.json should be left

6. Copy the domino-domino-db-1.0.0-package folder into the project folder

7. Create a file .dockerignore and with the following content:

node_modules
npm-debug.log

8. Create the Dockerfile with the following content:

FROM node:8

# Create app directory
WORKDIR /usr/src/app

# Install app dependencies
# A wildcard is used to ensure both package.json AND package-lock.json are copied
# where available (npm@5+)
COPY package*.json ./

# create a folder for the local domino-db package
RUN mkdir -p /src
COPY ./domino-domino-db-1.0.0-package /src/domino-domino-db-1.0.0-package

# install & rebuild
RUN npm install
RUN npm rebuild

# If you are building your code for production
# RUN npm install --only=production

# Bundle app source
COPY ./app .

EXPOSE 3000
CMD [ "npm", "start" ]

9. The directory structure should look like this:

/domino-express
   |-app
      |-...
   |-domino-domino-db-1.0.0-package
      |-...
   |-.dockerignore
   |-Dockerfile
   |-package.json

10. Add domino-db to package.json

{
  "name": "domino-express",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "node ./bin/www"
  },
  "dependencies": {
    "cookie-parser": "~1.4.3",
    "debug": "~2.6.9",
    "express": "~4.16.0",
    "http-errors": "~1.6.2",
    "jade": "~1.11.0",
    "morgan": "~1.9.0",
    "stylus": "0.54.5",
    "@domino/domino-db": "file:/src/domino-domino-db-1.0.0-package"
  }
}

11. Build the docker container (replace username with your docker id)

docker build -t {username}/domino-express .

12. Start the container

docker run -p 3000:3000 -d -it {username}/domino-express

13. Open it in your browser => http://localhost:3000
