How do you run it? docker exec?

How do you run it? docker exec?

Yes, you can do that, or I just docker exec -ti CONTAINER_NAME bash to get in, then run curl -fsS https://platform.sh/cli/installer | php

[pjcdawkins]

There is a --shell-type option on the installer which you could try:

curl -fsS https://platform.sh/cli/installer | php -- --shell-type bash
