Synopsis

  • Manage Hetzner’s dedicated server firewall.

Parameters

Parameter

Comments

hetzner_password

string / required

The password for the Robot web-service user.

hetzner_user

string / required

The username for the Robot web-service user.

server_ip

string

The server’s main IP address.

Exactly one of server_ip and server_number must be specified.

Note that Hetzner deprecated identifying the server’s firewall by the server’s main IP. Using this option can thus stop working at any time in the future. Use server_number instead.

server_number

integer

added in community.hrobot 1.8.0

The server’s number.

Exactly one of server_ip and server_number must be specified.

timeout

integer

Timeout (in seconds) for waiting for firewall to be configured.

Default: 180

wait_delay

integer

Delay to wait (in seconds) before checking again whether the firewall has been configured.

Default: 10

wait_for_configured

boolean

Whether to wait until the firewall has been successfully configured before returning from the module.

The API returns status in progress when the firewall is currently being configured. If this happens, the module will try again until the status changes to active or disabled.

Please note that there is a request limit. If you have to do multiple updates, it can be better to disable waiting, and regularly use community.hrobot.firewall_info to query status.

Choices:

  • false

  • true ← (default)
