ERROR: Invalid interpolation format for “image” (when installing docker)

i got error when installing frappe via docker , was using docker compose to run containers got this error "ERROR: Invalid interpolation format for “image” option in service “configurator”: “frappe/frappe-worker:${FRAPPE_VERSION:v14.12.1}” .And also please share if anyone have the documentation for frappe docker installation as i am a learning frappe from scratch . It would be lot of help if someone provide proper docker deployment of frappe.
Thanks!!
