## Synopsis

- This module can be used to configure, add or remove NTP servers from an ESXi host.

- If `state` is not given, the NTP servers will be configured in the exact sequence.

- User can specify an ESXi hostname or Cluster name. In case of cluster name, all ESXi hosts are updated.

## Requirements

The below requirements are needed on the host that executes this module.

- python >= 2.6

- PyVmomi

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
cluster_name string |  | Name of the cluster from which all host systems will be used. This parameter is required if `esxi_hostname` is not specified.
esxi_hostname string |  | Name of the host system to work with. This parameter is required if `cluster_name` is not specified.
hostname string |  | The hostname or IP address of the vSphere vCenter or ESXi server. If the value is not specified in the task, the value of environment variable `VMWARE_HOST` will be used instead. Environment variable support added in Ansible 2.6.
ntp_servers list / required |  | IP or FQDN of NTP server(s). This accepts a list of NTP servers. For multiple servers, please look at the examples.
password string |  | The password of the vSphere vCenter or ESXi server. If the value is not specified in the task, the value of environment variable `VMWARE_PASSWORD` will be used instead. Environment variable support added in Ansible 2.6. aliases: pass, pwd
port integer added in 2.5 | Default: 443 | The port number of the vSphere vCenter or ESXi server. If the value is not specified in the task, the value of environment variable `VMWARE_PORT` will be used instead. Environment variable support added in Ansible 2.6.
proxy_host string added in 2.9 |  | Address of a proxy that will receive all HTTPS requests and relay them. The format is a hostname or a IP. If the value is not specified in the task, the value of environment variable `VMWARE_PROXY_HOST` will be used instead. This feature depends on a version of pyvmomi greater than v6.7.1.2018.12
proxy_port integer added in 2.9 |  | Port of the HTTP proxy that will receive all HTTPS requests and relay them. If the value is not specified in the task, the value of environment variable `VMWARE_PROXY_PORT` will be used instead.

state

present: Add NTP server(s), if specified server(s) are absent else do nothing.
absent: Remove NTP server(s), if specified server(s) are present else do nothing.
Specified NTP server(s) will be configured if `state` isn't specified.

username string |  | The username of the vSphere vCenter or ESXi server. If the value is not specified in the task, the value of environment variable `VMWARE_USER` will be used instead. Environment variable support added in Ansible 2.6. aliases: admin, user

validate_certs
boolean

Choices:
- no
- yes ←

Allows connection when SSL certificates are not valid. Set to `false` when certificates are not trusted.
If the value is not specified in the task, the value of environment variable `VMWARE_VALIDATE_CERTS` will be used instead.

Verbose output of the configuration change.
Explains if an NTP server was added, removed, or if the NTP server sequence was changed.

## Notes

Note

- Tested on vSphere 6.5
