##### SUMMARY

`docker_container` module often fails because removal of `auto_remove: yes` takes some time. I had the same problem before with shell scripts since `docker stop` returns immediately but container removal takes some time to finish. Until removal is finished, no new container with the same name can be created.

The error message is:

    Error creating container: 409 Client Error: Conflict ("Conflict. The container name "/MYCONTAINER" is already in use by container "HASH". You have to remove (or rename) that container to be able to reuse that name.")

##### ISSUE TYPE
- Bug Report

##### COMPONENT NAME
docker_container

##### ANSIBLE VERSION
```
ansible 2.9.2
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/home/USER/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']

```

##### CONFIGURATION
_no changes_

##### OS / ENVIRONMENT
Ubuntu 19.10


##### STEPS TO REPRODUCE

0. Run playbook to create container
0. Apply many changes to the file system
0. Run playbook again

```yaml
docker_container:
  name: SOMETHING
  image: SOMETHING
  state: started
  detach: yes
  recreate: yes
  autoremove: yes
```

##### EXPECTED RESULTS
Wait for removal before trying to create a new container.


##### ACTUAL RESULTS
