SSIS deployment on databases part of AAG

Experts, I have two databases, one is SSISDB, other is user database. Both of them are a part of Always on availability group. I need to give one user a permission to be able to deploy a package. How should I go about doing this. He already has a login and has a data reader access to both the databases. We are talking about SQL server 2016 EE here.
Thanks.

You have 2 options.

1. Make the user a member of ssis_admin role which of course give more privilege than you intend to.

This role provides full administrative access to the SSIS Catalog
database.

2. You can give permission at folder level under integration services catalogs. Here you have a better control, but you have to do this for each folder.
