A simple social media app

A small project I used to study Node.js, ReactJS, MongoDB, Socket.IO, K8s and Jenkins.

Main features

• CRUD posts
• Like posts
• Follow an user
• Realtime chat
• Check online users

Build the app using Docker

Frontend

1. Build the image

• yarn build
• Run yarn build again if you change the variables in .env
• Using docker
  • Go to the directory that has your Dockerfile and run the following command to build the Docker image. The -t flag lets you tag your image so it's easier to find later using the docker images command
  • docker build . --rm -f Dockerfile -t nct_social_ui:r1
• Using docker-compose
  • docker-compose build nct_social_ui

2. Run the image

• Using docker:
  • Running your image with -d runs the container in detached mode, leaving the container running in the background. The -p flag redirects a public port to a private port inside the container
  • Map port 8002 in the server to port 80 in the container. We've already expose port 80 in Dockerfile
  • docker run --env-file=.env.dev --rm -p 8002:80 nct_social_ui:r1
• Using docker-compose
  • docker-compose up nct_social_ui
  • docker-compose --env-file client/.env.dev up nct_social_ui

Database

• docker-compose up mongo mongo-express
• Login to the database: mongo -u root -p 123456 --authenticationDatabase admin
• Connect to a remote database: mongo host:port/database -u username -p password
• Create an user: db.createUser({user:"writetApp", pwd:"writeApp", roles:[{role:"dbOwner", db:"social_media_app"}]});
• Get all users: db.getUsers();

Backend

1. Build the image

• docker build . -t nct_social_server:r1
• docker-compose build nct_social_server

2. Run the image

• docker run --env-file=.env.dev --rm -p 49160:8080 nct_social_server:r1
• docker-compose --env-file server/.env.dev up nct_social_server

Socket

1. Build the image

• docker build . -t nct_social_socket:r1
• docker-compose build nct_social_socket

2. Run the image

• docker run --env-file=.env.dev --rm -p 8900:8900 nct_social_socket:r1
• docker-compose --env-file socket/.env.dev up nct_social_socket

Jenkins

• Run jenkins.sh
• Run docker logs CONTAINER_ID or go to /var/jenkins_home/secrets/initialAdminPassword to get the password

Debug

• docker exec -it bash
