Excellent. Thanks so much @mdPlusPlus.

Hi there. This is a great tool. I'm testing it right now. One question, how do I set flow rules in the network?
Thank you

Not implemented in ztcui, you have to directly speak to the zerotier-one instance (I think JSON-RPC?). There was a pull request to get this feature merged into ztncui, but it was never cleanly submitted and the author has gone silent.

If anyone is willing to clean that up, I'm sure @key-networks would be willing to merge it: key-networks/ztncui#21

seems the zt version of this image is still 1.4.6 - would you mind updating the image to 1.6.2 please? I am still clueless on how to use your dockerfile and build my own.

https://hub.docker.com/r/keynetworks/ztncui now contains zerotier-one-1.6.2, no longer needs --cap-add=NET_ADMIN and avoids UID/GID clashes in Ubuntu.

@key-networks:

so I can switch from using
image: mdplusplus/zerotier-network-controller-ui
to
image: keynetworks/ztncui:latest

as you have included all the same fixes in your image?

In theory, yes. Just test and let us know how it goes.

Good to back up your data beforehand.

@key-networks: Good to see you still working on that project!

@mdPlusPlus: Thanks for your help with identifying the previous issues.
