Docker Environment variables property

Official Content
This documentation is valid for:
Set the environment variables you want the Dockerfile to include


What's written in the property gets added to the result dockerfile in a line starting with the ENV instruction. You can either set one variable (VAR=VALUE) or as many as you want to separate them with a space (VAR1=VALUE1 VAR2=VALUE2). Also, make sure you single quote the values that may contain spaces (VAR='THE VALUE').

After the image is created you can check its environment variables executing the following command.

docker inspect <image name> --format {{.ContainerConfig.Env}}

At runtime, you can check every environment variable with the Configuration Manager
