Note that preapply hooks will only run if at least one release has changes to apply. Be sure to make each preapply hook command idempotent. Otherwise, rerunning helmfile apply on a transient failure may end up either breaking your cluster, or the hook that runs for the second time will never succeed. `preuninstall` hooks are triggered immediately before a release is uninstalled as part of `helmfile apply`, `helmfile sync`, `helmfile delete`, and `helmfile destroy`.
