[olive ginkgo]

thanks, next/env is a package?

[patent wraith]

yeap

[olive ginkgo]

thank you, appreciate it! Havec you successfully done that?

[patent wraith]

check the docs https://nextjs.org/docs/pages/building-your-application/configuring/environment-variables

alternative methods are available

i didn't encounter the same problem but hope this will solve urs

[olive ginkgo]

Thank you, I will test it out, do you have to copy env file into docker image btw?

[patent wraith]

can u please tell me more specifically whats the problem is

why u need to copy it into docker image

for what ur using the docker

[olive ginkgo]

This is the first time I am trying to work with Dock and Next JS, everything works fine, except I don't know how to setup and config env file when building the image

I'm trying to self host

[patent wraith]

ohh u have to put the environment in the next configuration file and from there u can access it like this process.env.name

like u don't need to make a .env file for that

like this 'module.exports = {
env: {
customKey: 'my-value',
},
}'

hope u get it

[olive ginkgo]

oh, I see, to put all the env variables in the Next config ? so at the end of the day all the variables still live in the Docker image built right?

[patent wraith]

Yes, that's right. If you put environment variables in the Next.js config or .env files, and then build the Docker image, those variables will be part of the image. However, you can also pass them in at runtime when the container starts, which keeps them out of the image itself.

[olive ginkgo]

However, you can also pass them in at runtime when the container starts can you please explain how?

[patent wraith]

passing the env variables explicitly as arguments to rhe docker

command

docker run -e NEXT_PUBLIC_API_URL=https://api.example.com -e SECRET_KEY=mysecretkey -p 3000:3000 my-next-app

[olive ginkgo]

you mean pass them in the Dockerfile directly?

[patent wraith]

not to dockerfile but to pass them to the docker when it starts

like in the above command

for what u are using the docker

??

[olive ginkgo]

Got you, why am I using Docker? Just trying to self host on AWS

[patent wraith]

so 2 ways to start the docker container either access them from the .env or access them directly at docker run time

[olive ginkgo]

Got it, thanks man

[patent wraith]
