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.

Options

parameter required default choices comments
connect_timeout
 no 5
The maximum number of seconds to wait for a connection to happen before closing and retrying.
delay
 no
The number of seconds to wait before starting to poll.
exclude_hosts
 no
The list of hosts or IPs to ignore when looking for active TCP connections when state=drained.
host
 no 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
 no
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
 no
The port number to poll on host.
search_regex
 no
Can be used to match a string in a file.
If state is present or started then it will wait until the regex matches.
If state is absent then it will wait until the regex does not match.
Defaults to a multiline regex.
sleep
 no 1
Number of seconds to sleep between checks.
state
 no started
  • present
  • started
  • stopped
  • absent
  • drained
When checking a port, started will ensure the port is open, stopped will check that is it closed and drained will check for active connections.
When checking for a file or a search string present or started will ensure that the file or string is present, absent will check that the file or search string is absent or removed.
timeout
 no 300

- name: wait 300 seconds for port 8000 to become open on the host, don't start checking for 10 seconds
  win_wait_for:
    port: 8000
    delay: 10

- name: wait 150 seconds for port 8000 of any IP to close active connections
  win_wait_for:
    host: 0.0.0.0
    port: 8000
    state: drained
    timeout: 150

- name: wait for port 8000 of any IP to close active connection, ignoring certain hosts
  win_wait_for:
    host: 0.0.0.0
    port: 8000
    state: drained
    exclude_hosts: ['10.2.1.2', '10.2.1.3']

- name: wait for file C:\temp\log.txt to exist before continuing
  win_wait_for:
    path: C:\temp\log.txt

- name: wait until process complete is in the file before continuing
  win_wait_for:
    path: C:\temp\log.txt
    search_regex: process complete

- name: wait until file if removed
  win_wait_for:
    path: C:\temp\log.txt
    state: absent

- name: wait until port 1234 is offline but try every 10 seconds
  win_wait_for:

    state: absent
    sleep: 10
