If importing data

4. Transfer data with scp -s -r /local/path/to/data server-ssh-name@ssh.frankfurt.render.com:/var/data
   • Get the server address from the Connect > SSH button on the service page
   • The remote path /var/data should match the one you defined in step 2
5. Update any ENV variables to point to this path
6. If you want to use the path in the Dockerfile, use the ARG command after the first from statement:

FROM node:18-alpine as base
WORKDIR /usr/src/app
ARG ENV_VAR_NAME_POINTING_TO_DATA
# Do smth with the path
CMD foo $ENV_VAR_NAME_POINTING_TO_DATA
