ansible.builtin.wait_for module – Waits for a condition before continuing

Synopsis

• You can wait for a set amount of time timeout, this is the default if nothing is specified or just timeout is specified. This does not produce an error.
• 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.
• It is also useful when starting guests with the community.libvirt.virt module and needing to pause until they are ready.
• This module can also be used to wait for a regex match a string to be present in a file.
• In Ansible 1.6 and later, this module can also be used to wait for a file to be available or absent on the filesystem.
• In Ansible 1.8 and later, this module can also be used to wait for active connections to be closed before continuing, useful if a node is being rotated out of a load balancer pool.
• For Windows targets, use the ansible.windows.win_wait_for module instead.
