pre_install_script and post_install_script for workers

[dsalaza4]

Describe the solution you'd like

Currently, runners support start_script, pre_install_script and post_install_script via runner_install parameter.

But it seems like workers only support start_script via runner_worker_docker_machine_instance parameter.

This makes it impossible to run commands on workers right before or after base setup.

Suggest a solution

• Support pre_install_script and post_install_script via runner_worker_docker_machine_instance parameter.

Additional context

Good point. This might also be helpful for #1118

Not sure if this is possible. The start_script is used as user data script on the EC2 instance.

[dsalaza4]

What's more important in my opinion is being able to prepend/append custom code to the worker user data.

If start_script is currently used, then I would advise only supporting pre_start_script and post_start_script so users can do whatever they want before or after that baseline configuration.

Any idea how to add this? I can't find any option for the Fleeting plugin (docker+autoscaler) and the same goes for docker+machine

I did not have time to check this and ended up solving my specific necessity differently.

I think we can close this as it looks like no one actually has needed it so far! 🫶
