1. build a tagged Docker image
2. push it into Docker repository
3. force Kubernetes rolling deployment within selected namespace

example:

cp ./build.sh /usr/local/bin/build

2. Add required environment variables listed in .env file into your project .env where Dockerfile is located

example:

cat ./env >> /path_to_your_project_where_Dockerfile_is_located/.env
