community.vmware.vmware_host_dns module – Manage DNS configuration of an ESXi host system

Note

This module is part of the community.vmware collection (version 2.9.1).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.vmware.

To use it in a playbook, specify: community.vmware.vmware_host_dns.

Synopsis

  • This module can be used to configure DNS for the default TCP/IP stack on an ESXi host system.

Parameters

Parameter

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 and you connect to a vCenter.

Cannot be used when you connect directly to an ESXi host.

device

string

The VMkernel network adapter to obtain DNS settings from.

Needs to get its IP through DHCP, a static network configuration combined with a dynamic DNS configuration doesn’t work.

The parameter is only required in case of type is set to dhcp.

dns_servers

list / elements=string

A list of DNS servers to be used.

The order of the DNS servers is important as they are used consecutively in order.

domain

string

The domain name to be used for the ESXi host.

esxi_hostname

string

Name of the host system to work with.

This parameter is required if cluster_name is not specified and you connect to a vCenter.

Cannot be used when you connect directly to an ESXi host.

host_name

string

The hostname to be used for the ESXi host.

Cannot be used when configuring a complete cluster.

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.

password

aliases: pass, pwd

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.

port

integer

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.

Default: 443

proxy_host

string

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

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.

search_domains

list / elements=string

A list of domains to be searched through by the resolver.

type

string / required

Type of DNS assignment. Either dhcp or static.

A VMkernel adapter needs to be set to DHCP if type is set to dhcp.

Choices:

  • dhcp

  • static

username

aliases: admin, user

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.

validate_certs

boolean

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.

Environment variable support added in Ansible 2.6.

If set to true, please make sure Python >= 2.7.9 is installed on the given machine.

Choices:

  • no

  • yes ← (default)

verbose

boolean

Verbose output of the DNS server configuration change.

Explains if an DNS server was added, removed, or if the DNS server sequence was changed.

Choices:

  • no ← (default)

  • yes

Notes

Note

  • This module is a replacement for the module vmware_dns_config

  • All modules requires API write access and hence is not supported on a free ESXi license.
