docker-compose breaks ssh connection, and quick docker-compose test

& useful info :

upon ssh in to a vm, you can see IP address allocated by docker bridge and ur host :

  Users logged in:                  2

  IPv4 address for br-4e87e62c362f: 10.10.47.1

  IPv4 address for br-5f57f2b334ae: 10.10.1.1

  IPv4 address for docker0:         10.10.0.1

  IPv4 address for ens160:          172.16.100.100

 docker compose breaks ssh connection :

https://stackoverflow.com/questions/41736187/docker-compose-network-creation-kicks-me-out-of-ssh

try :

    docker network ls

then check 

    docker ps 

to see if any network is being used by containers

then do 

    docker network rm xxxx

to keep 

    bridge, host, none

This should immidately resolve docker-compose 

freezes user and suddenly u have ssh broken pipe issue, and never able to ssh agin.

If docker-compose up (doing docker-compose build breaks ssh)

 

sudo vim /etc/docker/dameon.json

add a default address pool for bridge network to ensure its not inconflict with other IPS in the network like :

{

 "default-address-pools":

 [

 {"base":"10.26.0.1/16","size":24}

 ],

}

quickly test docker compose
