A small titbit to share today, the Makefile.
A Makefile can be used to define sets of commonly used commands to save time and to ensure the commands run in the correct order with needed pre-requisites.
For example, you can define a list of build-related commands under a target called “build”.
build:
docker-compose build image-1
docker-compose push image-1 Then next time you can execute the build by calling “make build”, instead of manually typing out all the commands in sequence.
Recently I have started to use it more often, as it really simplifies the development and deployment steps.
(p/s: In case you are wondering about the GPG_TTY environment variable, that is needed for GPG to properly prompt for the password when docker is authenticating with its private container registry.)
