```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:
      TZ: Europe/Paris
    volumes:
      - 'nfsdata:/nexus-data:nocopy'
      - 'nfsbackup:/backup'
```
##### EXPECTED RESULTS
Beeing able to access the volume within the container like in :  

```sh
[root@LX01665L ~]# docker run --rm -ti -v nfsdata:/test --name test alpine /bin/sh
/ # 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
elasticsearch        javaprefs            orient
/ #
```

##### ACTUAL RESULTS
The task crash with (NB, accordingly to the documentation in https://docs.ansible.com/ansible/latest/modules/docker_container_module.html where it's not specified beeing usable ) : 

```
fatal: [lx01665l.tb.uro.equant.com]: FAILED! => {"changed": false, "msg": "Found invalid volumes mode: nocopy"}

        When the container is created by this module, its C(StopTimeout) configuration
        will be set to this value.
      - When the container is stopped, will be used as a timeout for stopping the
        container. In case the container has a custom C(StopTimeout) configuration,
        the behavior depends on the version of the docker daemon. New versions of
        the docker daemon will always use the container's configured C(StopTimeout)
        value if it has been configured.
