Docker-Compose v3 - static ip - docker

Question

I am trying to set a static IP on my docker-compose v3 file but.. i can't.
Each time I set it, I can't connect to the webpage anymore.
I am getting ERR_ADDRESS_UNREACHABLE
Here is my config:
# docker-compose.yml
version: '3'
services:
web:
build: ./etc/nginx
ports:
- "90:80"
volumes:
- "./etc/ssl:/etc/ssl"
depends_on:
- php
- database
php:
build: ./etc/php
ports:
- 9000:9000
links:
- database:mysqldb
volumes:
- "./etc/php/php.ini:/usr/local/etc/php/conf.d/php.ini"
- ${APP_PATH}:/var/www/symfony
database:
image: mysql
environment:
MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD}
MYSQL_DATABASE: ${MYSQL_DATABASE}
MYSQL_USER: ${MYSQL_USER}
MYSQL_PASSWORD: ${MYSQL_PASSWORD}
ports:
- 3300:3306
volumes:
- "./data/db/mysql:/var/lib/mysql"
and
# docker-compose.override.yml
version: '3'
services:
web:
networks:
test:
ipv4_address: '10.1.0.100'
networks:
test:
ipam:
driver: default
config:
- subnet: 10.1.0.0/24

Answer 1

It should be like this:
services:
web:
networks:
test:
ipv4_address: 10.1.0.100
networks:
test:
driver: bridge
ipam:
driver: default
config:
- subnet: 10.1.0.0/24
And in my case I placed networks section before services.
UPDATE:
eventually I've ended up using external network for like this:
docker network create --subnet 10.5.0.0/24 local_network_dev
and then in any docker-compose you can just use it like this:
version: '3.2'
networks:
default:
external:
name: local_network_dev
and inside of image:
web:
networks:
default:
ipv4_address: 10.5.0.11

Answer 3

Just a very important note that should all future users know.
If you are trying to edit already existing network, you will most likely get error
Cannot start service xxx: Invalid address xxx.xxx.xxx.xxx: It does not belong to any of this network's subnets
I have been struggling for about 2 hours with this problem. The solution is to set a different name for the network or propably use docker-compose down.
Networks settings is not much different between versions 2 and 3, but here is a good link to official doc (v3): https://docs.docker.com/compose/compose-file/compose-file-v3/#ipv4_address-ipv6_address
