Docker-Compose 通过 .env 传递命令参数

Question

I often need to start Odoo server with different arguments.

So in docker-compose.yml, which is versioned, I specified the following:

version: '3'
services:
  web:
    image: odoo:12.0
    command: odoo ${ODOO_ARGS}

and created a .env file with:

ODOO_ARGS="--update=all"

This works well with a single argument, but it doesn't handle multiple arguments. For example if I try the following:

ODOO_ARGS="--database=myDb --update=all --stop-after-init"

the command will be evaluated as: odoo --database="myDb --update=all --stop-after-init"

I pretty sure it is a syntax issue, so I'd like to know how to pass multiple arguments to the command option through .env file.

It actually evaluates to odoo "--database=myDb --update=all --stop-after-init" just because you put quotes in the env file. Here is an example with several arguments in one string:

docker-compose.yml

version: "3.7"

services:
  test:
    image: debian:buster
    command: find ${ARGS}

.env

ARGS=/ -name bash

Running this you'll get:

test_1  | /bin/bash
test_1  | /usr/share/lintian/overrides/bash
test_1  | /usr/share/menu/bash
test_1  | /usr/share/doc/bash
