This patch adds the ceph-csi-rbd helm chart component to the metal
cluster type. The purpose is to enable PersistentVolumeClaims on ois
metal clusters.
Cloud clusters like GKE and EKS are expected to skip rendering the metal
type.
Helm values are handled with CUE. The ceph secret is managed as an
ExternalSecret resource, appended to the rendered output by cue and the
holos cli.
Use:
❯ holos render --cluster-name=k2 ~/workspace/holos-run/holos/docs/examples/platforms/reference/clusters/metal/...
2:45PM INF render.go:40 rendered prod-metal-ceph version=0.47.0 status=ok action=rendered name=prod-metal-ceph
This patch validates secrets are synced from the provisioner cluster to
a workload cluster. This verifies the eso-creds-refresher job, external
secrets operator, etc...
Refer to

for the corresponding commit on the k2 cluster.
This patch prints out the cue file and line numbers when a cue error
contains multiple go errors to unwrap.
For example:
```
❯ holos render --cluster-name=k2 ~/workspace/holos-run/holos/docs/examples/platforms/reference/clusters/workload/...
3:31PM ERR could not execute version=0.46.0 err="could not decode: content: error in call to encoding/yaml.MarshalStream: incomplete value string (and 1 more errors)" loc=builder.go:212
content: error in call to encoding/yaml.MarshalStream: incomplete value string:

/home/jeff/workspace/holos-run/holos/docs/examples/cue.mod/gen/external-secrets.io/externalsecret/v1beta1/types_gen.cue:83:14
```
This patch adds the `eso-creds-refresher` CronJob which executes every 8
hours in the holos-system namespace of each workload cluster. The job
creates Secrets with a `token` field representing the id token
credential for a SecretStore to use when synchronizing secrets to and
from the provisioner cluster.
Service accounts in the provisioner cluster are selected with
selector=holos.run/job.name=eso-creds-refresher.
Each selected service account has a token issued with a 12 hour
expiration ttl and is stored in a Secret matching the service account
name in the same namespace in the workload cluster.
The job takes about 25 seconds to run once the image is cached on the
node.
Without this patch the Job on a workload cluster fails with:
```
+ kubectl get serviceaccount -A --selector=holos.run/job.name=eso-creds-refresher --output=json
Error from server (Forbidden): serviceaccounts is forbidden: User
"eso-creds-refresher@holos-run.iam.gserviceaccount.com" cannot list
resource "serviceaccounts" in API group "" at the cluster scope:
requires one of ["container.serviceAccounts.list"] permission(s).
```
This label is intended for the Job to select which service accounts to
issue tokens for. For example:
kubectl get serviceaccount -A --selector=holos.run/job.name=eso-creds-refresher --output=json
Without this patch it is difficult to navigate the structure of the
configuration of the api objects because they're positional elements in
a list.
This patch extracts the configuration of the eso-reader and eso-writer
ServiceAccount, Role, and RoleBinding structs into a definition that
behaves like a function. The individual objects are fields of the
struct instead of positional elements in a list.
This patch adds a ConfigMap and Pod to the eso-creds-refresher
component. The Pod executes the gcloud container, impersonates the
eso-creds-refresher iam service account using workload identity, then
authenticates to the remote provisioner cluster.
This is the foundation for a script to automatically create Secret API
objects in a workload cluster which have a kubernetes service account
token ESO SecretStore resources can use to fetch secrets from the
provisioner cluster.
Once we have that script in place we can turn this Pod into a Job and
replace Vault.
The provisioner cluster is a worker-less autopilot cluster that provides
secrets to other clusters in the platform. The `eso-creds-refresher`
Job in the holos-system namespace of each other cluster refreshes
service account tokens for SecretStores.
This patch adds the IAM structure for the Job implemented by Namespace,
ServiceAccount, Role, and RoleBinding api objects.
