How to share the git commit log with the customer without giving access to the repository?

I want to share the progress of the project with the customer. I need to show him that im working on it constantly. The best way to do is to show the comit log. But to show it, I have to give him access to my repo (Bitbucket or Github). How can I do this without giving access to the repo?

How do I share a git repository with others?

Under your repository name, click Settings. In the "Access" section of the sidebar, click Collaborators & teams. Click Invite a collaborator. In the search field, start typing the name of person you want to invite, then click a name in the list of matches.

I have seen another alternative:

set a post-receive hook (or a webhook) on the private repo (server side) which will:
- do a git log and redirect the result in a text file
- save that text file in a dedicated repo (which includes only the log text file)

That way, you give access to that log repo, and the client can follow the log in it.
