11/06/2022, 1:52 PMI am trying to get netclient to run on a kubernetes cluster. I have read the docs here:
https://k8s.netmaker.org/
And have also looked at the examples in the git repository here:
https://github.com/gravitl/netmak8s
Nothing appears to work as expected. Are the instructions out of date?
For example: the netclient:v0.9.3 container image used in the examples appears not to support the current Token format. When using with a token from a 0.16.2 installation the command complaints the no server is defined.
When I switch to the netclient:latest image I get an image that requires kernel wireguard. It does not (as indicated in the docs) use userspace wireguard.
There exists a netmaker-userpace image, but there is no documentation on how to use that one. I tried starting it, and it appears to run (nodes appear on the netmaker dashboard) but still cannot communicate.

11/06/2022, 1:53 PMNow I can see the node on my netmaker server. but cannot ping it.
In the container log I see the following:

11/07/2022, 10:59 AMWhat I am trying to do is make a service on my openshift cluster available via the netmaker network.
I want to follow the instrcutions on k8s.netmaker.org

11/07/2022, 10:59 AMI want to do a containerized client install.

11/07/2022, 11:00 AMProblem is that the normal docker image requires wg support in the linux kernel.

11/07/2022, 11:00 AMThis does not work on openshift.

11/07/2022, 11:00 AMSo I need to somehow use a docker image with userspace support.
hundreds-needle-744
11/07/2022, 11:00 AMSo I found that there were a netclient-go and netclient-userspace container images. And thus I tried these. But they do not work either.

11/07/2022, 11:06 AMSo I am trying different use cases. Getting the worker node on the network is one, but just networking a single pod (using a sidecar) is another. But that requires the the dockerised netclient works.

11/07/2022, 11:07 AMNext thing I tried was building the container image myself. But that does not work either...I get compilation errors there.

11/07/2022, 11:55 AMSo any help would be appreciated here.
