I have an unbound DNS server on my network that I use for certain configuration. My IncusOS machine is properly using this server, and caching the queries for containers.
I ended up changing a DNS record in Unbound, and wanted to tell IncusOS to flush the DNS cache to pick up the change, but it seems like this is not exposed (at least in the UI).
Not currently supported. Running incus admin os system network edit and just saving without changing anything “may” cause a flush.
Feel free to file a feature request in GitHub · Where software is built, it should be pretty easy to add an extra API route and CLI command to flush the DNS cache.
