System Requirement

Before you use the Docker to deploy the project, you need to ensure you have download below software:

Docker (Please refer Docker official file to get the installation instructions) Docker Compose Installation

Download and unzip the source code for the project

Access the project directory after unzipped the file

Execute the following command to build the Docker mirror image:

./build.sh [TAG]

It will use Dockerfile to set up the Docker mirror image named lottery:[TAG]. If no tag is specified, the 'latest' tag is used by default

Execute the following command to run the local container:

./dev.sh [TAG]

This will start the container and deploy the application in the Docker container. You can test loacally to ensure all running fulently.
Please be pay attention that all applicaiton in the container will monitor port 8888 and port 443.

Execute the following command to tag the Docker mirror image and push it to the remote Docker repository

./tagpush.sh [TAG]

It will tag the Docker mirror image and push it to the remote Docker repository, please build up your repo at https://hub.docker.com/ if you want to us Docker official hub.
