Frequently Asked Questions

INPUT_BUILD_ARGS is not working

It's a common use case to pass build arguments to the docker command using environment variables, so the first thing you would run is something like this

INPUT_BUILD_ARGS=NODE_VERSION=24.0.0,NODE_ENV=production nx run node-app:container

But as you can notice, it do not work as you expect 😢

The problem is because both variables should be separated by a new line instead a comma and you have two ways to do it

Using dotenv

Create a .env file in the root of the workspace with this content

INPUT_BUILD_ARGS="NODE_VERSION=24.0.0\nNODE_ENV=production"

Take a look of the \n between both variables, then run nx run node-app:container

Inline execution

Sadly, the string of the first option not work if you try to run INPUT_BUILD_ARGS="NODE_VERSION=24.0.0\nNODE_ENV=production" nx run node-app:container, in this case you need to use a new line instead of \n like the below image

INPUT_TAGS is not working with container-metadata

This specific case is for the container-metadata tags, and is the same issue of INPUT_BUILD_ARGS, please apply the same solutions described above
