When using Docker, we distinguish between two different types of variables - ARG and ENV. ARG are also known as build-time variables. They are only available from the moment they are ‘announced’ in the Dockerfile with an ARG instruction up to the moment when the image is built. Running containers can’t access values of ARG variables.

When starting our container in production we only need to set the environment variable value in the second $ docker run -e "ENV_VAR=foo" ubuntu /bin/bash Both -e and --env can be used to define environment variables inside of a container.

In development, the application is running on webpack-dev-server after the container is started. In production, our React application needs this variable during the build itself. In order to fix this, we can use build arguments in our docker-compose.yml.
Several environment variables are available for you to configure the Docker Compose command-line behavior. They begin with COMPOSE_ or DOCKER_, and are documented in CLI Environment Variables. Environment variables created by links 🔗 When using the ‘links’ option in a v1 Compose file, environment variables are created for each link.

On first glance, this approach may seem to bring too small of a benefit for the extra work it requires for initial setup. But once setup is done, environment specific configurations and deployment will be way easier to handle. While you can’t directly set ENV variable values when running docker build, you can use ARG to pass through --build-arg values right into your ENV instructions. First, you’ll need to define an additional ARG variable, which is only there to pass through the value to your environment variable: Set Docker Environment Variables During Build Time Apr 7 th , 2018 9:51 am When using that ARG option in your Dockerfile, you can specify the --build-args option to define the value for the key that you specify in your Dockerfile to use for a environment variable as an example.

Several environment variables are available for you to configure the Docker Compose command-line behaviour. Variables starting with DOCKER_ are the same as those used to configure the Docker command-line client. If you’re using docker-machine, then the eval "$ (docker-machine env my-docker-vm)" command should set them to their correct values. Docker has support for environment variables to be set in a variety of different ways, and these Docker environment variables are loaded automatically into our ASP.NET Core application as part of the AddEnvironmentVariables method.
