Docker dockerfile

• FROM: base image

FROM alpine:latest

• LABEL: metadata

• CMD: default executable run by the container (can be overridden)

• ENTRYPOINT: like CMD but cannot be overridden

• EXPOSE: what port the container app is running on (metadata only, not a config)

Command creating new layers

Those commands create a new layer. Less layer == better so minimize them.

• RUN: execute command in a new layer

• COPY: copies NEW files/folder from host to container

• ADD: like COPY but can be from a remote url
