You can do this in a few ways you can do this:
Use bash -c:
Eg.
command: bash -c "python manage.py migrate && python manage.py runserver 0.0.0.0:8000"
OR
command: >
bash -c "python manage.py migrate
&& python manage.py runserver 0.0.0.0:8000"
OR
command: bash -c "
python manage.py migrate
&& python manage.py runserver 0.0.0.0:8000
"
But be sure to check if the image you are using this command with actually has bash intalled inside of it. A few images don't come with bash installed in them and with a few images you need to put the exact path for bash to work, like so: /bin/bash
Use sh -c:
If bash is not installed on the image you want to work with , you can use sh -c, here is an example on how you can do so:
version: '3'
services:
app:
build:
context: .
command: >
sh -c "python manage.py wait_for_db &&
python manage.py migrate &&
python manage.py runserver 0.0.0.0:8000"
Use ephemeral containers:
In this third way you simply write the commands in two separate containers, like given below:
db:
image: postgres
web:
image: app
command: python manage.py runserver 0.0.0.0:8000
volumes:
- .:/code
ports:
- "8000:8000"
links:
- db
depends_on:
- migration
migration:
build: .
image: app
command: python manage.py migrate
volumes:
- .:/code
links:
- db
depends_on:
- db
It makes things clean and organised, but it would be tedious to do this with multiple commands and there are some logical issues with the use of depends_on.
Hope this helped :)
