Node_container folder

Here we are going to focus on the Mongo server and Java services.

Go to /opt/zw-vmmc-docker/services/ and create .env file:

vim /opt/zw-vmmc-docker/node_container/services/.env

And paste the next content:

MONGO_LOCATION="mongo:27017"
MONGO_USER_PASS="<user>:<pwd>"
KAFKA_BROKER="kafka-broker:9092"

You will need to replace “<user>” and “<pwd>” with the same user and password existing in: mongo-user // TODO

Continue creating the file ecosystem.config.js in the same folder:

vim /opt/zw-vmmc-docker/node_container/services/ecosystem.config.js

Copy the next lines on the file you are creating:

module.exports = {
  apps: [
    {
      name: 'queue-service',
      script: './queue-service.js', 
      instances: '1',
      },
    {
      name: 'cronWs',
      script: './connect-cron/src/app.js',
      instances: '1',
      env: {
        PORT: 3002,
      },
    },
    {
      name: 'mongo',
      script: '/usr/src/app/connectMongo/nodeJsWs/mongo.js',
      instances: '1',
      exec_mode: 'cluster',
      env: {
        PORT: 3000,
      },
    },
  ],
};

After that, we will need to get the services. To get the resources you need to access to GitHub and download the next releases:
All these folder haves to be moved to /opt/zw-vmmc-docker/node_container/services
The last step in the node_container folder is to create the dockerfile in /opt/zw-vmmc-docker/node_container :
```
vim /opt/zw-vmmc-docker/tomcat/dockerfile
```

With the next content:

# nodeapp/Dockerfile

# Use the Mongo Docker Official Image
FROM node:20-alpine

# set the folder to copy the services
WORKDIR /usr/src/app
COPY services/ .

# Install pm2 globally
RUN apk add --no-cache bash-completion 
RUN apk add --no-cache vim
RUN npm install pm2 -g

WORKDIR /usr/src/app/connect-cron
RUN npm install

WORKDIR /usr/src/app/connectMongo/nodeJsWs
RUN npm install

WORKDIR /usr/src/app
CMD ["sh", "-c", "cd /usr/src/app/connect-cron && npm install && cd /usr/src/app/connectMongo/nodeJsWs && npm install && cd /usr/src/app && pm2-runtime ecosystem.config.js"]

EXPOSE 3000

Create a Docker Compose file in the /opt directory
