Login into Github Container Registry

Login into Github Container Registry with your username and the personal access token we got in the previous step.

Build Docker image and Tag the image

# cd into you dockerized project
docker build -t IMAGE_NAME:VERSION  . 

# re-tag the image with ghcr path
docker tag IMAGE_NAME:VERSION ghcr.io/GITHUB_USERNAME_OR_ORG_NAME/IMAGE_NAME:VERSION
