Answer
Init scripts provide a method to pre-install binaries or set initial configurations without the need to modify the base image (1) . They are executed at the beginning when the worker starts, ensuring that any necessary binaries or configurations are set up before the worker undertakes any other job .
To preinstall jq using init scripts, you can use the following approach:
Init scripts are available only on self-hosting and enterprise edition on private clusters . Any scripts are set from the Worker Management UI, at the worker group level . Any script content specified in
INIT_SCRIPT will be executed at the beginning when each worker of the worker group starts .
When adjustments are made in the Worker Management UI, the workers will shut down and are expected to be restarted by their supervisor (Docker or k8s) . The execution of Init scripts is inspectable in the superadmin workspace, with Kind = All filter . The path of those executions are init_script_{worker_name} .
For API-based management, you can also configure init scripts programmatically through Windmill's API by updating the worker group configuration with the desired init script content.
