Добрый день!

Помогите с настройкой postgresql в docker

Имеется 2 виртуальные машины с ip 192.168.56.101 (master) и 192.168.56.102(slave)
docker-compose.yml

version: '2'

services:
psql_master:
image: 'docker.io/postgres:9.6.3'
volumes:
- '/home/vagrant/psql/data:/var/lib/postgresql/data'

recovery.conf

standby_mode = 'on'
primary_conninfo = 'host=192.168.56.101 port=5432 user=postgres password=postgres'
trigger_file = '/var/lib/postgresql/data/trigger'

Мастер запускается нормально, но при запуске слейва :

psql_slave_1 | LOG: database system was shut down in recovery at 2017-06-22 14:36:25 UTC
psql_slave_1 | LOG: entering standby mode
psql_slave_1 | LOG: redo starts at 0/C000028
psql_slave_1 | LOG: invalid record length at 0/C000108: wanted 24, got 0
psql_slave_1 | FATAL: could not connect to the primary server: could not connect to server: Connection refused
psql_slave_1 | Is the server running on host "192.168.56.101" and accepting
psql_slave_1 | TCP/IP connections on port 5432?
