Versions of gnatsd and affected client libraries used:

2.0.0

OS/Container environment:

Kubernetes 1.14

Steps or code to reproduce the issue:

Ensure that you have a working version of the nats operator installed in a Kubernetes cluster
kubectl apply the following file
`apiVersion: nats.io/v1alpha2
kind: NatsCluster
metadata:
name: nats-cluster
spec:
size: 3
version: "2.0.0"

Expected result:

A running NATS Cluster

Actual result:

A not running NATS Cluster

Right because there is no symlink for gnatsd in the FROM scratch image... Need to update the operator for this, but you can use this image instead which we also maintain:

serverImage: "synadia/nats-server"
version: "2.0.0"

Heh, I think it would work but currently there's no ARM build.

[wallyqs]

I will take a look at pushing a version of the operator where this is fixed tomorrow. If you want to try to create your own arm image for now, this is the Dockerfile that can be used to generate an 2.0.0 compatible image: https://github.com/nats-io/nats-server/blob/master/docker/Dockerfile.alpine

Thanks, I'll for sure take a look at it. Does the build system support cross-compilation? I could tackle getting this and the streaming operator working with ARM by emulating how the nats-server build and docker generation happens.

[wallyqs]

hey @charles-d-burton, the dockerfile I shared does not support cross compilation, but also I am about to merge #195 and then push the image of the operator this morning that would support 2.0.0 image. I pushed my own image here for now wallyqs/nats-operator:0.6.0 but think won't work on ARM as is right now, contributions on getting the operator running on ARM very welcome too 👍

[wallyqs]

Fixed via #195
