Since Oracle is providing free cloud instance resources for lifetime (Cloud Free Tier | Oracle India) there is a possibility of hosting the passbolt on the cloud forever for free. But can you please make a simple documentation of how we can achieve this?
As it’s outside of what the team has already documented, it would be hard to provide community-based support for it. But, if you end up giving this a try, the community can certainly benefit from hearing what it took to accomplish. Many other users have contributed like this related to something new.
Also, if you have not installed passbolt before it would be good to start with that first, using existing documentation.
