# Using DevOps Hooks

|   |                                                                                                                                                                                       |

Our DevOps hooks are build-specific scripts that are called, or can be called, by the `entrypoint.sh` script used to start our product containers.

|   | Use of the hook scripts is intended only for DevOps professionals familiar with the products. |

The available hooks are built into the product images and can be found in the `hooks` subdirectory of each product directory in the [Docker Builds](https://github.com/pingidentity/pingidentity-docker-builds) repository.

In the `entrypoint.sh` startup script, there is an example (stub) provided for the available hooks for all products.

|   | It is **critical** that the supplied hook names be used if you modify `entrypoint.sh`. For example, they can be used to make subtle changes to a server profile. |

## Using .pre and .post hooks

When the hook scripts are called during the `entrypoint.sh` initialization, any corresponding `.pre` and `.post` hooks are also called.

The `.pre` and `.post` extensions allow you to define custom scripts to be executed before or after any hook that is run in the container. You can include any custom `.pre` and `.post` hooks in the `hooks` directory of your server profile.

Hooks with a `.pre` extension are run before the corresponding hook, and hooks with a `.post` extension are run after the corresponding hook.

For example, a script named `80-post-start.sh.pre` will execute immediately before the `80-post-start.sh` hook and a script named `80-post-start.sh.post` will be run immediately after that hook completes.
