Use Cron trigger to create a recurrent execution of Codefresh pipeline(s).

It is possible to define and manage Cron-based pipeline triggers with Codefresh UI.

To add a new Cron trigger, navigate to Codefresh Pipeline *Configuration* view and expand *Triggers* section. Press the `Add Trigger` button and select a `Cron` trigger type to add.


Visit [this page](https://github.com/codefresh-io/cronus/blob/master/docs/expression.md) to learn about supported `cron` expression format and aliases.

Fill the following information:

* Use Cron helper wizard to build a valid `cron` expression or write custom `cron` expression on last tab

* Add a free text message, that will be sent as additional event payload every time `cron` is executed


Now, `cron` will trigger a recurrent pipeline execution based on defined `cron expression`.

It is possible to use `codefresh` command line client (`CLI`) to manage Cron based pipeline triggers.

It is possible to define and manage DockerHub pipeline triggers with Codefresh UI.

To add a new DockerHub trigger, navigate to Codefresh Pipeline *Configuration* view and expand *Triggers* section. Press the `Add Trigger` button and select a `Registry` trigger type to add.


Fill the following information:

* Registry Provider - select `DockerHub`

* *Namespace* - put DockerHub user name or organization name here

* *Name* - DockerHub image repository name

* *Action* - select `Push Image` action

* *Filter* - optional filter to specify which image *tags* will trigger pipeline execution: [Re2](https://github.com/google/re2/wiki/Syntax) regular expression


Currently Codefresh does not support to automatically setup a DockerHub webhook. You need to do this manually. Press `View Trigger` button and see detailed instructions with URL links and secrets of how-to setup a DockerHub Webhook.


1. copy `Endpoint` URL

1. visit DockerHub image settings page following link in help

1. add a new DockerHub Webhook with previously copied `Endpoint` URL

Now, every time you push a new Docker image to selected DockerHub repository, manually, with Codefresh or any other CI/CD tool, Codefresh will trigger execution of all pipelines associated with this DockerHub Push trigger event.

It is possible to use `codefresh` command line client (`CLI`) to manage DockerHub pipeline triggers.
