Hello,

rke support Weave https://github.com/rancher/rke#network-plugins since this PR rancher/rke#81
Do you have any news about when it will be integrated in Rancher 2?

Thanks!

Currently, weave is already supported in RKE. We should add UI support to display the weave options in the drop down.

For those looking to use weave, you can edit the yaml of a RKE cluster and input your own network plug-in.

The Weave UI also needs to support the ability to enable encryption through a PR like rancher/rke#781 in order for this issue to be complete

@Oats87: spoke with @vincent99 about the flow. The plan is for the UI to generate the password by default whenever Weave provider is picked from the drop down, and if user wants a custom password, he'd have to modify it in the cluster.yml. The requirements for password generation is yet to be determined, will update the ticket once figured.

Verified UI is posting field and API is returning. Sending to Sangeetha to verify backend is functioning properly.

@tfiduccia Weave allows traffic encryption. How will this be solved in Rancher/Rancher Web Interface?

According to the Weave documentation we need to set --password option or WEAVE_PASSWORD https://www.weave.works/docs/net/latest/tasks/manage/security-untrusted-networks/

[vincent99]

As we said above, it is set to a random password because there's no reason for most people to customize it.

When network mode is set to cluster , use cases relating to portmapping, ingress, Service Discovery work as expected.
There is 1 issue with hostPort not working as expected, which is tracked in #17336
