I've been trying to get this to work for the past few weeks with very limited success. Keep in mind Service Mesh can include Jaeger, ElasticSearch, and Kiali along with the base Istio components and Prometheus, and they need alot of resources. Don't even consider trying it without giving your CRC VM a minimum of 4 CPUs (I've only had luck with 5 myself). And don't even consider trying it without giving your CRC VM at least 20 GB RAM (and even that probably isn't enough). I would think giving your CRC VM 32GB RAM should be enough, but I don't have that much RAM to try and confirm. I don't know the magic number, but I'm pretty confident in saying that anything lower than 20 GB RAM will not work. You might have better luck by disabling Grafana, Jaeger, and Kiali in the ServiceMeshControlPlane CR - that would reduce the amount of resource you will require. But once you add in demo apps like bookinfo and you start sending in traffic to your mesh, that will creep up more resource usage. In short, if you plan on trying this with CRC, give the CRC VM as much CPU and memory as you can spare. For the record, here is a hack script I've been using to start up Service Mesh on CRC - it shows the commands I've been using to try to get this to work: https://github.com/kiali/kiali/blob/master/hack/crc-openshift.sh ___ users mailing list users@lists.openshift.redhat.com http://lists.openshift.redhat.com/openshiftmm/listinfo/users

Marvin, you could try enabling nested virtualisation in GCP? https://cloud.google.com/compute/docs/instances/enable-nested-virtualization-vm-instances On Fri, 20 Sep 2019 at 09:50, Just Marvin < marvin.the.cynical.ro...@gmail.com> wrote: > Fernando, > > Is CRC only expected to run on bare-metal?

CRC and OpenShift Service Mesh?
Hi, Are these [1] instructions expected to work for CRC as well, or are there different instructions / its not possible to get the istio working on CRC?

Re: [OKD/OCP v4]: deployment on a single node using CodeReady Container
Fernando, Is CRC only expected to run on bare-metal? I tried running it on a VM in GCP and it didn't work, complaining about virtualization problems (sorry - forget the exact error). It runs find on my laptop, but I'd really like to not muddy up my laptop with all kinds of experimental things.
