 原文  2016-09-26 09:33:49  7   1    docker/ docker-compose

Question

How can I interpolate env vars when using docker-compose . if I have a following vars.env file :

VAR_1=value_1
VAR_2=value_1/value2
VAR_3=value_1/value3

I would like to interpolate using of VAR_1 like this

VAR_1=value_1
VAR_2=${VAR_1}/value2
VAR_3=${VAR_1}/value3

But it is not working. Any idea ?

This is not supported. You can however use an .env file to set the value of $VAR_1 : https://docs.docker.com/compose/env-file/
