Ansible error when executing openwhisk.yml with ansible-playbook

## Environment details:

Ubuntu 18 with docker version 20.10.2

## Steps to reproduce the issue:

1. Deployed openwhisk locally using CouchDB and Ansible. I changed CouchDB's IP address to node's public ip
2. ansible-playbook openwhisk.yml

## Provide the expected results and outputs:

```
Expect to finish without error and bring up a docker of controller successfully. Currently "docker ps" only shows zookeeper, couchDB and wurstmeister/kafka:2.13-2.7.0
```

## Provide the actual results and outputs:

```

## Additional information you deem important:
* issue happens only occasionally or under certain circumstances
* changes you did or observed in the environment

Reproduce the failure with ansible-playbook openwhisk.yml on Ubuntu 18 and Docker 20.10.2, then inspect the controller task and the configuration passed to the Docker container module, focusing on the invalid pid_mode value. Done means the playbook completes without error and the controller container appears in docker ps.
