I am using docker compose version 3.3 and want to use environment variable to define the volume name. I looked at a related question, but that seems to be quite old. With long syntax supported in 3.2, is there a way to achieve that? Here is what I tried in my docker compose file:
version: '3.3'
services:
target:
image: "my-registry/my-image:${IMAGE_TAG}"
volumes:
- type: volume
source: ${VOLUME_NAME}
target: /data
ports:
- "${TOMCAT_PORT}:8080"
volumes:
${VOLUME_NAME}:
Obviously this syntax does not work as volume name is not substituted in the keys and throws the following error:
volumes value Additional properties are not allowed (‘${VOLUME_NAME}’ was unexpected)
Any help will be much appreciated.
