The Infisical Operator is a collection of Kubernetes controllers that streamline how secrets are managed between Infisical and your Kubernetes cluster. It provides multiple Custom Resource Definitions (CRDs) which enable you to:
  • Sync secrets from Infisical into Kubernetes (InfisicalSecret).
  • Push new secrets from Kubernetes to Infisical (InfisicalPushSecret).
  • Manage dynamic secrets and automatically create time-bound leases (InfisicalDynamicSecret).
When these CRDs are configured, the Infisical Operator will continuously monitors for changes and performs necessary updates to keep your Kubernetes secrets up to date. It can also automatically reload dependent Deployments resources whenever relevant secrets are updated.
If you are already using the External Secrets operator, you can view the integration documentation for it here.

​
Install

The operator can be install via Helm. Helm is a package manager for Kubernetes that allows you to define, install, and upgrade Kubernetes applications. Install the latest Helm repository 
helm repo add infisical-helm-charts 'https://dl.cloudsmith.io/public/infisical/helm-charts/helm/charts/' 

helm repo update
The operator can be installed either cluster-wide or restricted to a specific namespace. If you require stronger isolation and stricter access controls, a namespace-scoped installation may make more sense. 
helm install --generate-name infisical-helm-charts/secrets-operator

​
Custom Resource Definitions

Currently the operator supports the following CRD’s. We are constantly expanding the functionality of the operator, and this list will be updated as new CRD’s are added.
  1. InfisicalSecret: Sync secrets from Infisical to a Kubernetes secret.
  2. InfisicalPushSecret: Push secrets from a Kubernetes secret to Infisical.
  3. InfisicalDynamicSecret: Sync dynamic secrets and create leases automatically in Kubernetes.

​
General Configuration

​
Private/self-signed certificate

To connect to Infisical instances behind a private/self-signed certificate, you can configure the TLS settings in the CRD to point to a CA certificate stored in a Kubernetes secret resource. 
---
spec:
  hostAPI: https://app.infisical.com/api
  tls:
    caRef:
      secretName: custom-ca-certificate
      secretNamespace: default
      key: ca.crt
---

​
Global configuration

To configure global settings that will apply to all instances of InfisicalSecret, you can define these configurations in a Kubernetes ConfigMap. For example, you can configure all InfisicalSecret instances to fetch secrets from a single backend API without specifying the hostAPI parameter for each instance.

​
Available global properties

PropertyDescriptionDefault value
hostAPIIf hostAPI in InfisicalSecret instance is left empty, this value will be usedhttps://app.infisical.com/api

​
Applying global configurations

All global configurations must reside in a Kubernetes ConfigMap named infisical-config in the namespace infisical-operator-system. To apply global configuration to the operator, copy the following yaml into infisical-config.yaml file.
infisical-config.yaml
apiVersion: v1
kind: Namespace
metadata:
  name: infisical-operator-system
---
apiVersion: v1
kind: ConfigMap
metadata:
  name: infisical-config
  namespace: infisical-operator-system
data:
  hostAPI: https://example.com/api # <-- global hostAPI
Then apply this change via kubectl by running the following 
kubectl apply -f infisical-config.yaml

​
Troubleshoot operator

If the operator is unable to fetch secrets from the API, it will not affect the managed Kubernetes secret. It will continue attempting to reconnect to the API indefinitely. The InfisicalSecret resource uses the status.conditions field to report its current state and any errors encountered. 
$ kubectl get infisicalSecrets
NAME                     AGE
infisicalsecret-sample   12s

$ kubectl describe infisicalSecret infisicalsecret-sample

Uninstall Operator

The managed secret created by the operator will not be deleted when the operator is uninstalled.
