Creating a Dockerfile with Environment Variables

To create a Dockerfile that can take environment variables, you can use the ENV instruction in the Dockerfile. This instruction is used to set environment variables in the container. Here's a simple example of how you can achieve this:

Create a Dockerfile: You can create a Dockerfile with the following content to demonstrate the use of environment variables:

FROM alpine
ENV MY_ENV_VAR="default_value"
CMD echo "The value of MY_ENV_VAR is $MY_ENV_VAR"

In this example, the ENV instruction sets the environment variable MY_ENV_VAR with a default value. The CMD instruction then uses this environment variable in the command to be executed when the container starts.

Build the Docker Image: After creating the Dockerfile, you can build the Docker image using the following command:

docker build -t my_image .

This command builds the Docker image based on the Dockerfile in the current directory and tags it with the name my_image.

Run the Docker Container: Once the image is built, you can run a container based on this image and override the default value of the environment variable if needed. Here's an example command to run the container:

docker run -e MY_ENV_VAR="custom_value" my_image

In this command, the -e flag is used to set the value of the environment variable MY_ENV_VAR to "custom_value" when running the container.

By following these steps, you can create a Dockerfile that effectively utilizes environment variables to pass configuration information to containers at runtime, allowing for flexibility and security in managing different environments. Environment variables are key-value pairs that contain data used by processes running inside a Docker container.
