ERROR: only one instance of "host" network is allowed

[biot023]

Hi – I’m having difficulty with using the host network driver.
I have a networks section at the end of my docker-compose.yml file:

version: "3"
services:
    ...
networks:
    default:
        driver: host

However, when I try to run this with docker-compose up I get this error:

Creating network “0_dev_default” with driver “host”
ERROR: only one instance of “host” network is allowed

There aren’t any other containers running when I do a docker ps or anything.
Can anyone advise me on what I’m getting wrong?
Thanks for any and all assistance,
Doug.

Hello,
I have the same problem.
My docker-compose.yml :
version: ‘2’
services:

   nginx:
     image: myapp/nginx:v1.14
     ports: 
       - "80:80"
       - "443:443"
     networks: 
       - "host"
   
   mysql:
     image: myapp/mysql:v5.7.24
     ports: 
       - "3306:3306"
     networks: 
       - "host"

 networks:
   host:
     driver: host

When I run command “docker-compose up” display error is as follow

Creating network “docker_host” with driver “host”
ERROR: only one instance of “host” network is allowed

How should me solve the problem？
