We use Consul and we are willing to enforce that developers can alter it only using git2consul approach, to retain the history of property changes and maintain a backup.
In order to ensure that, we would like to make Consul Key-Value browser UI read-only. How could we achieve this?
Consul Web UI is an ember gui on-top of the Consul API, using the same methods as the tools using Consul. Therefore you should be able to configure the web UI using the ACL system to restrict use to READ only on scopes needed.
There is a Github Issue talking about this here: https://github.com/hashicorp/consul/issues/3399
