Docker Assignments #6: Docker, Node and helloworld.js

1. Create a folder with name it as “docker-helloworld” in your host machine
2. Create a file with name “helloworld.js”  under “docker-helloworld” folder
3. Add console.log statement with sample message in helloworld.js file
4. Pull alpine node docker image into your host machine
5. Write docker run command by setting following options

• set container name as "nodehelloworld"
• set container working directory i.e. /usr/app
• do bind-mount of “docker-helloworld” folder from host machine to container /usr/app folder
• run hello-world.js

      6. Check console.log message on the terminal

 Command:

> docker run

   -w /usr/app

   --mount type=bind,source=/c/Users/rama/docker-helloworld,target=/usr/app

   --name nodehelloworld

   mhart/alpine-node node helloworld.js 

  (or)

> docker run 

  -w //usr/app 

  --mount type=bind,source=$(pwd),target=/usr/app 

  --name nodehelloworld  

  mhart/alpine-node node helloworld.js

• -w  --> used for setting container working directory
• --mount --> used for bindmount/volume
• --name --> used for specifying container name
• mhart/alpine-node  --> alpine node image
• node helloworld.js --> run node command in the container

Happy Coding :)
