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.

Advanced usage

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 repository.

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

Warning

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.
