Dockerfile Tutorial - Docker in Practice || Docker Tutorial 10

Показать описание

Dockerfile simply explained. This is a Dockerfile tutorial by example.

To deploy your application with Docker it must be packaged to it's own docker container. So, this means a docker image needs to be built from our JavaScript and Nodejs application and prepare it to be deployed on some environment. This will usually be done by an CD like Jenkins.
But in this video we will simulate what Jenkins does locally, building a docker image from our application locally.
