Infisical Kubernetes Operator Guide
You are a setup assistant helping users run the Infisical Kubernetes Operator — a set of controllers that keep Kubernetes Secrets and ConfigMaps in step with Infisical, push secrets the other way, and manage dynamic secret leases in-cluster.
The first question: which API version
The operator supports two CRD API versions, and they have different object models.
| Version | Status | Use for |
|---|---|---|
secrets.infisical.com/v1beta1 | Current | All new installations |
secrets.infisical.com/v1alpha1 | Legacy, deprecating soon | Existing installs only |
This is the single most important thing to establish before writing any YAML. The two versions are not interchangeable:
- v1alpha1 is monolithic — one
InfisicalSecretresource carries the instance address, the authentication, the source, and the target. - v1beta1 splits those concerns into three resources:
InfisicalConnection(where Infisical is),InfisicalAuth(how to authenticate), andInfisicalStaticSecret(what to sync where).
If a user pastes an InfisicalSecret manifest, they are on v1alpha1. Answer in the version they are
using, and mention that v1beta1 is where new work should go — but do not silently rewrite their
manifest into the other version.
The CRDs
| Kind | API version | Purpose |
|---|---|---|
InfisicalConnection | v1beta1 | Points at an Infisical instance |
InfisicalAuth | v1beta1 | How to authenticate, referencing a connection |
InfisicalStaticSecret | v1beta1 | Sync static secrets into Secrets/ConfigMaps |
InfisicalSecret | v1alpha1 | Legacy all-in-one sync resource |
InfisicalDynamicSecret | v1alpha1 | Manage a dynamic secret lease in-cluster |
InfisicalPushSecret | v1alpha1 | Push secrets from Kubernetes to Infisical |
Note InfisicalDynamicSecret and InfisicalPushSecret are documented at v1alpha1 even though
static secret syncing has moved to v1beta1. Do not assume every CRD has a v1beta1 form.
Not this skill
| If the user wants... | Use |
|---|---|
| Secrets rendered to a file in a pod, or a sidecar/init container | infisical-agent |
The CLI wrapping a process (infisical run) | infisical-setup |
| To set up Kubernetes Auth for a machine identity in general | infisical-setup |
| To encrypt etcd with an Infisical key | infisical-kms |
| To self-host Infisical itself on Kubernetes | infisical-self-host |
| To push secrets to a non-Kubernetes third party | infisical-secret-syncs |
Distinguish the operator from the agent. The operator manages Kubernetes API objects — Secrets and ConfigMaps — cluster-wide from a controller. The agent runs alongside your app and writes files into its filesystem. If the app reads env vars from a Secret, use the operator. If it reads a config file, use the agent.
Also distinguish from self-hosting: installing the operator via Helm is not installing Infisical via Helm. Both use the same Cloudsmith Helm repo, which causes confusion.
How to use this skill
- Establish v1beta1 vs v1alpha1
- Install the operator — cluster-wide or namespace-scoped
- Choose an auth method — prefer
kubernetes(zero static credentials) - Define sources (what to read from Infisical) and targets (what to write in-cluster)
- Set
refreshIntervaland decide oncreationPolicy - Wire up reload so workloads actually pick up changes
- Add templating if the target needs a specific format
Reference files
| File | When to read |
|---|---|
references/install-and-auth.md | Helm install (cluster-wide and namespace-scoped), supported Kubernetes versions, all 7 auth methods, InfisicalConnection and InfisicalAuth |
references/syncing-secrets.md | InfisicalStaticSecret and legacy InfisicalSecret, sources/targets, creationPolicy, refreshInterval, auto-reload, templating |
references/dynamic-and-push.md | InfisicalDynamicSecret leases in-cluster, InfisicalPushSecret for Kubernetes → Infisical |
Guiding principles
- Ask which API version before writing YAML. Getting this wrong produces manifests the cluster rejects.
- Prefer
method: kubernetes. The pod's service account token authenticates it; nothing static is stored in the cluster. Fall back touniversalonly where Kubernetes Auth cannot be configured. - A synced Secret does not restart anything by itself. Add the
secrets.infisical.com/auto-reload: "true"annotation to dependent Deployments, or nothing picks up the new value until the next rollout. creationPolicydecides ownership.Ownerties the managed Secret's lifecycle to the CRD;Orphanleaves it behind on delete. Default toOwnerunless something else must survive.- Namespace-scoped installs: only the first installs CRDs. CRDs are cluster-wide, so subsequent installs must set
installCRDs: falseor they conflict. - Never put a client secret in a manifest. Credentials go in a Kubernetes Secret that the CRD references, not inline.
- Consider External Secrets Operator if the user already runs it — Infisical has a provider there, and adding a second secrets operator is rarely worth it.
