How do I configure environment variables in Docker?
You can configure environment variables in Docker using the -e flag in the docker run command or by using a .env file.
Can you give me an example of using a .env file?
Sure! Create a .env file with key-value pairs like DB_USER=myuser and then use --env-file .env when running your container.
What if I want to set them in a Dockerfile?
You can use the ENV instruction in your Dockerfile, like this: ENV DB_USER=myuser.
Are there any security concerns with using environment variables?
Yes, be cautious with sensitive data. Avoid hardcoding secrets in your Dockerfile or .env files.
