Dockerizing brX GraphQL Service

Introduction

The brX GraphQL Service project includes an example Dockerfile and docker-compose.yml file for Docker-based software packaging, deployment, and managing scalable containers. These examples can be used as-is or customized for your own requirements.

Default Example Dockerfile

The default example Dockerfile looks as follows:

FROM node:alpine

COPY . /app
WORKDIR /app

RUN npm install && npm run build

EXPOSE 4000

ENTRYPOINT ["npm", "run"]
CMD ["start"]

You can customize the script (e.g, port number to expose) if necessary.

You can build a Docker image of the brX GraphQL Service as follows:

docker build -t bloomreach/brx-apollo-server:latest .

The above command will build a Docker image with the tag, "bloomreach/brx-apollo-server:latest", for example.

You can run the Docker image like the following example, publishing a container’s port, 4000, to the host's port, 4000:

docker run -p4000:4000 bloomreach/brx-apollo-server:latest

Default Example Docker Composition

The default example docker-compose.yml looks as follows:

version: '3.7'

services:
  graphql-commerce-connector-service:
    build:
      context: .
    container_name: graphql-commerce-connector-service
    image: bloomreach/graphql-commerce-connector-service:latest
    ports:
      - '4000:4000'
    environment:
      NODE_ENV=production
      APOLLO_INTROSPECTION=false
      APOLLO_PLAYGROUND=false
      LOG_LEVEL=info
      BRSM_API=https://core.dxpapi.com/api
      BRSM_SUGGEST_API=https://suggest.dxpapi.com/api
      BRSM_ACCOUNT_ID=0000
      BRSM_DOMAIN_KEY=mydomain
      JWK_KEYSTORE={...}
      # ...SNIP...

You can customize the script (e.g, port number to expose, environment variables, etc.) if necessary.

You can build images as follows:

docker-compose build

You can also build and run the images as follows:

docker-compose up
