```yaml
- name: start nexus_ihm services
  docker_container:
    name: nexus_ihm
    image: '{{ docker_images.nexus_ihm.image }}:{{ docker_images.nexus_ihm.version }}'
    state: started
    recreate: yes
    log_driver: json-file
    restart_policy: 'unless-stopped'
    hostname: nexus_ihm
    env:

/ # ls /test/
config.json  init-stdin   init-stdout
/ # exit
[root@LX01665L ~]# docker run --rm -ti -v nfsdata:/test:nocopy --name test alpine /bin/sh
/ # ls /test/
backup               etc                  kar                  port
blobs                generated-bundles    keystores            restore-from-backup
cache                health-check         lock                 tmp
db                   instances            log                  upgrades
