Github actions workflow to docker container environment

Question

I have the following environment variable set in GitHub workflow file (on the top level):

env: 
  GITHUB_RUN_NUMBER: ${github.run_number}

I would like to access it in my docker container (frontend-react) and log in console:

console.log(`Build number= ${process.env.GITHUB_RUN_NUMBER}`)

Currently, the GITHUB_RUN_NUMBER does not reach the container build in the workflow exec container env

How should I pass environment variables from workflow to container? Thanks!

on:

  workflow_dispatch
    
env: 
  GITHUB_RUN_NUMBER: ${github.run_number}

The missing step was defining the variable in Docker file as mentioned by aknosis
