Docker Hello World Example Project

This is a simple Docker example project that demonstrates how to build and run a basic Ubuntu container and execute a simple script.

.
├── .cnb.yml          # Build configuration file
└── docker/
    ├── Dockerfile    # Docker image definition
    └── setup.sh      # Script executed in the container

This project creates a Docker container based on Ubuntu 18.04 and executes a simple script in the container that outputs a "hello" message.

1. Build the Docker image:

docker build -t hello-docker -f docker/Dockerfile .

2. Run the Docker container:

docker run --rm hello-docker /app/setup.sh

The project includes a .cnb.yml configuration file that can be used for automated build and deployment processes. This configuration specifies using docker/Dockerfile for building and uses the docker/setup.sh script during the build process.

You can customize the project by modifying the following files:

• docker/Dockerfile: Change the base image or add more build steps
• docker/setup.sh: Modify the operations performed when the container starts

• Docker
