win_wait_for – Waits for a condition before continuing
New in version 2.4.
Synopsis
- You can wait for a set amount of time
timeout
, this is the default if nothing is specified. - Waiting for a port to become available is useful for when services are not immediately available after their init scripts return which is true of certain Java application servers.
- You can wait for a file to exist or not exist on the filesystem.
- This module can also be used to wait for a regex match string to be present in a file.
- You can wait for active connections to be closed before continuing on a local port.
Parameters
Parameter | Choices/Defaults | Comments |

connect_timeout integer | Default: 5 | The maximum number of seconds to wait for a connection to happen before closing and retrying. |
delay integer | The number of seconds to wait before starting to poll. | |
exclude_hosts list | The list of hosts or IPs to ignore when looking for active TCP connections when state=drained . | |
host string | Default: "127.0.0.1" | A resolvable hostname or IP address to wait for. If state=drained then it will only check for connections on the IP specified, you can use '0.0.0.0' to use all host IPs. |
path path | The path to a file on the filesystem to check. If state is present or started then it will wait until the file exists.If state is absent then it will wait until the file does not exist. | |
port integer | The port number to poll on host . | |
