I have the same error message "❯ ERROR: Your configured RAM_SIZE of 1 GB is too high for the 1 GB of memory available, please set a lower value." although the docker host has 4GB Ram of which 1.2GB is shown as free plus 1GB unused swap file.

You can add -e RAM_CHECK=N to force the script to continue even with low RAM.
