Question/issue around Talos bootstrap with Cluster API & vSphere infrastructure (CAPV) #179

Open julien-sugg opened 10 months ago

julien-sugg commented 10 months ago

Greetings,

We've been playing with Talos Linux and Cluster API to automate the management of our clusters, and are currently facing some questions/issues around the bootstrap process using the vSphere infrastructure provider.

Versions / Environment

Description

According to the Talos - VMware documentation, we have to install a custom talos-vmtools with some dedicated Talos config.

This totally makes senses, however, my concern if the following:

In order to bootstrap the cluster via Cluster API, and especially the CACPPT controller, I need my CAPV controller to retrieve the IP address of the VM via the vCenter API. However, such IP is only available upon successful installation and configuration of the VMTools. Unfortunately, to install the VMTools, I need to necessarily have the Talos bootstrap done due to the fact that it is deployed as a DaemonSet. This makes us hit the chicken/egg problem.

Our current workaround is to manually bootstrap the cluster via the IP addresses provided by the DHCP. However, this is quite a pain as we wish to automate everything via GitOps since we will manage quite a lot of permanent clusters, but also some ephemeral ones.

Do you have any insights or recommendations to achieve such goal using the VMware ecosystem ?

Reproduce Steps

The following steps can be performed to easily reproduce the issue:

  1. Create a transient cluster that will be used to spawn the first permanent management cluster via Cluster API.

The cluster can either be created directly on vSphere or kind/k3d/...

  1. Initialize Cluster API components on the transient cluster with clusterctl with CAPV, CABPT and CACPPT
clusterctl init \
--infrastructure vsphere:v1.8.1 \
--bootstrap talos:v0.6.2 \
--control-plane talos:v0.5.3 \
--target-namespace cluster-api-system
  1. Create the permanent management cluster with the following minimal manifests:

  1. Once the VMs are created, confirm that the bootstrap cannot occur since VMTools cannot be installed and the bootstrap cannot be done either as it cannot reach the VMs due to the lack of IP Addresses at vCenter level.

Thanks in advance for your help and insights.

It was discussed in community Slack, but it didn't quite go that far.

VMWare users need to reimplement vmtoolsd to be a Talos system extension (and an extension service), this way it will run always with the machine.

Another option is to make Talos itself report IPs, if we can do that without pulling all VMWare libraries in.

Hi everyone, I face the same problem right now. Are there any updates or instructions to follow to work around this?

amaol-vestas commented 1 week ago

Also interested to see the fix for this issue, thanks?

amaol-vestas commented 1 week ago

I found a way to deploy, just create a TalosOS with vmtoolds installed by default using Talos image fabric and the use that one as baseline template for the deployment, please check here [https://factory.talos.dev/].
