cloud-init iso inject failed: unable to inject CloudInit ISO: unexpected end of JSON input #252

Closed justinas-b closed 4 months ago

justinas-b commented 4 months ago

What steps did you take and what happened: I am trying to provision my first cluster, however after first virtual machine is created i see below error:

E0701 21:46:45.868816       1 proxmoxmachine_controller.go:209] "error reconciling VM" err="cloud-init iso inject failed: unable to inject CloudInit ISO: unexpected end of JSON input" controller="proxmoxmachine" controllerGroup="infrastructure.cluster.x-k8s.io" controllerKind="ProxmoxMachine" ProxmoxMachine="default/mgmt-control-plane-wcsjg" namespace="default" name="mgmt-control-plane-wcsjg" reconcileID="69a7bb6b-77c2-4973-ba9a-176db57eb584" machine="default/mgmt-control-plane-wcsjg" cluster="default/mgmt"

I am using below configuration to bootstrap cluster:

export PROXMOX_URL="https://pve.mydomain.net"
export PROXMOX_TOKEN='svc-pve@MYDOMAIN.NET!aaaaaaaa-bbbb-cccc-dddd-ffffffffffff'
export PROXMOX_SECRET='11111111-2222-3333-4444-555555555555'

export MEMORY_MIB="1024"

clusterctl init --infrastructure proxmox --ipam in-cluster --core cluster-api:v1.7.2

clusterctl generate cluster mgmt \
    --infrastructure proxmox \
    --kubernetes-version v1.30.2 \
    --control-plane-machine-count 1 \
    --worker-machine-count 1 > ionos.yaml

What did you expect to happen: New virtual machines/cluster to be provisioned

Environment:

If i check the secrets, output of it looks like yaml, definitely not json:

❯ kubectl get secret "mgmt-control-plane-m6hs6" -o json -n default | jq -r '.data.value' | base64 -d
## template: jinja
#cloud-config

Seems to be related to https://github.com/luthermonson/go-proxmox/issues/115, which looks like to be addressed in v.0.1.0 version of go-proxmox package. And it seems that this package version is used in v0.5.1 providers version (https://github.com/ionos-cloud/cluster-api-provider-proxmox/commit/f9c532bfe946bb05f33f20145ea01ccfb4e622b3)m but i am still experiencing this issue

justinas-b commented 4 months ago

Looking at the logs it seems that responce with storage devices contains 3 devices, and i am wondering if those a filtered and only single storage device which meets requirements for ISO images is passed, or are all three storage devices passed to request which causes this error

justinas-b commented 4 months ago

Managed to connect with dlv debug - it seems error is caused in [task, err := storage.Upload("iso", iso.Name())]](https://github.com/luthermonson/go-proxmox/blob/215b6c1cd08a8743314218f35c05898740dcc3c2/virtual_machine.go#L148-L151). Exact exception is invalid character 'B' looking for beginning of value"

image

But i cannot understand from where this 'B' comes in the error

justinas-b commented 4 months ago

Hmm, i see that response to upload operation is actually "Bad Gateway", which probably explains B letter

image
justinas-b commented 4 months ago

OK, it seems issue was related to privileges on proxmox. User i am using didn't had necessary privileges to upload ISO image which resulted in "unexpected end of JSON input" error
