Incompatible CNI versions

[jralmaraz]

Hi Evan,

First of all, thank you so much for this project, this is just unbelievably great. I am an ops guys trying to learn go, been researching around containerd and ended-up on your awesome project.

I have installed the latest CNI version following a cillium project doc (https://cilium.readthedocs.io/en/v1.1/kubernetes/install/) as I did not have loopback before.

I thought of raising this issue to ask you what would be the recommended approach, like updating the plugin to use 0.3.1 or for me to downgrade the CNI (couldn't find the right key to download the 0.3.0 version yet) ?

jralmaraz@jralmaraz-vn:~/git/stellar$ sudo sctl --addr 127.0.0.1:9000 apps create -f ./example.conf
FATA[0000] rpc error: code = Unknown desc = incompatible CNI versions; config is "0.3.1", plugin supports ["0.1.0" "0.2.0" "0.3.0"]

Thanks in advance and happy new year !

Cheers,

Jose

Greetings! Thanks for the kind words and for checking it out :)

I suggest to upgrade the plugins. It looks like they have some pre-built available on the CNI plugins releases page (https://github.com/containernetworking/plugins/releases). FWIW I build from master and it seems to work well so their plugins should work fine.

Yeah, I shouldn't have trusted the CNI version on the cillium doc, re-built it correctly and it worked.

Thank you very much!

If there is anything that a newbie could contribute with this project, any simple task that would give me a chance to learn more about development in go, let me know, I would be pleased to do so.

Cheers and thanks again!

Awesome! I have a written roadmap that I'm going to convert into a project in Github. This should make it easier to contribute. Thanks for the interest!!

Sure @ehazlett, I'll keep my eyes open and keen to do something useful. Happy 2019! Cheers.
