Learn how to use the InfisicalSecret CRD to fetch secrets from Infisical and store them as native Kubernetes secret resource
The InfisicalSecret CRD is deprecated and will be removed in a future release.
For new installations, use InfisicalStaticSecret (v1beta1) instead.
See the migration guide for further details.
Once you have installed the operator to your cluster, you’ll need to create a InfisicalSecret custom resource definition (CRD).
In this CRD, you’ll define the authentication method to use, the secrets to fetch, and the target location to store the secrets within your cluster.
example-infisical-secret-crd.yaml
apiVersion: secrets.infisical.com/v1alpha1kind: InfisicalSecretmetadata: name: infisicalsecret-sample labels: label-to-be-passed-to-managed-secret: sample-value annotations: example.com/annotation-to-be-passed-to-managed-secret: "sample-value"spec: hostAPI: https://app.infisical.com/api syncConfig: resyncInterval: 10s instantUpdates: false authentication: kubernetesAuth: identityId: <machine-identity-id> serviceAccountRef: name: <service-account-name> namespace: <service-account-namespace> secretsScope: projectSlug: <project-slug> envSlug: <env-slug> # "dev", "staging", "prod", etc.. secretsPath: "<secrets-path>" # Root is "/" recursive: true # Whether or not to use recursive mode (fetches all secrets in an environment from a given secret path, and all folders inside the path) / defaults to false managedKubeSecretReferences: - secretName: managed-secret secretNamespace: default creationPolicy: "Orphan" template: includeAllSecrets: true data: NEW_KEY_NAME: "{{ .KEY.SecretPath }} {{ .KEY.Value }}" KEY_WITH_BINARY_VALUE: "{{ .KEY.SecretPath }} {{ .KEY.Value }}"
The following properties help define what instance of Infisical the operator will interact with, the interval it will sync secrets and any CA certificates that may be required to connect.
hostAPI
If you are fetching secrets from a self-hosted instance of Infisical set the value of hostAPI to
https://your-self-hosted-instace.com/apiWhen hostAPI is not defined the operator fetches secrets from Infisical Cloud.
Advanced use case
If you have installed your Infisical instance within the same cluster as the Infisical operator, you can optionally access the Infisical backend’s service directly without having to route through the public internet.
To achieve this, use the following address for the hostAPI field:
Make sure to replace <backend-svc-name> and <namespace> with the appropriate values for your backend service and namespace.
syncConfig
This block defines the synchronization configuration for the operator to fetch secrets from Infisical.
syncConfig.resyncInterval
The resyncInterval is a string-formatted duration that defines the time between each resync. The field is optional, and will default to 60 seconds if not defined.The format of the field is [duration][unit] where duration is a number and unit is a string representing the unit of time.The following units are supported:
s for seconds (must be at least 5 seconds)
m for minutes
h for hours
d for days
w for weeks
The default value is 1m(1 minute) when instantUpdates is set to false, and 1h(1 hour) when instantUpdates is set to true.Valid expressions for the resyncInterval field:
This property enables instant updates from Infisical. When set to true,
changes made to secrets in Infisical will be immediately pushed to the
operator, triggering a configuration update. This reduces the need for
periodic re-syncs.
Instant updates leverages Event Subscriptions to receive real-time updates when secret changes occur within Infisical.
Instant Updates is a paid featureInstant Updates is available under the Enterprise Tier.
Please contact sales@infisical.com for more information.
tls
This block defines the TLS settings to use for connecting to the Infisical
instance.
tls.caRef
This block defines the reference to the CA certificate to use for connecting
to the Infisical instance with SSL/TLS.
tls.caRef.secretName
The name of the Kubernetes secret containing the CA certificate to use for
connecting to the Infisical instance with SSL/TLS.
tls.caRef.secretNamespace
The namespace of the Kubernetes secret containing the CA certificate to use
for connecting to the Infisical instance with SSL/TLS.
tls.caRef.key
The name of the key in the Kubernetes secret which contains the value of the
CA certificate to use for connecting to the Infisical instance with SSL/TLS.
To retrieve the requested secrets, the operator must first authenticate with Infisical.
The list of available authentication methods are shown below.
authentication
This block defines the authentication credentials and secrets scope to be used when fetching secrets from Infisical.
authentication.universalAuth
The universal machine identity authentication method is used to authenticate with Infisical. The client ID and client secret needs to be stored in a Kubernetes secret. This block defines the reference to the name and namespace of secret that stores these credentials.
Once you have created your machine identity and added it to your project(s), you will need to create a Kubernetes secret containing the identity credentials.
To quickly create a Kubernetes secret containing the identity credentials, you can run the command below.Make sure you replace <your-identity-client-id> with the identity client ID and <your-identity-client-secret> with the identity client secret.
Add reference for the Kubernetes secret containing the identity credentials
Once the secret is created, add the secretName and secretNamespace of the secret that was just created under authentication.universalAuth.credentialsRef field in the InfisicalSecret resource.
Make sure to also populate the secretsScope field with the project slug
projectSlug, environment slug envSlug, and secrets path
secretsPath that you want to fetch secrets from. Please see the example
below.
apiVersion: secrets.infisical.com/v1alpha1kind: InfisicalSecretmetadata: name: infisicalsecret-sample-crdspec: authentication: universalAuth: secretsScope: # either projectSlug or projectId is required projectSlug: <project-slug> # <-- project slug projectId: <project-id> # <-- project id secretName: <secret-name> # OPTIONAL: If you want to fetch a single Infisical secret, you can specify the secret name here. If not specified, all secrets in the specified scope will be fetched. envSlug: <env-slug> # "dev", "staging", "prod", etc.. secretsPath: "<secrets-path>" # Root is "/" credentialsRef: secretName: universal-auth-credentials # <-- name of the Kubernetes secret that stores our machine identity credentials secretNamespace: default # <-- namespace of the Kubernetes secret that stores our machine identity credentials ...
authentication.kubernetesAuth
The Kubernetes machine identity authentication method is used to authenticate with Infisical. The identity ID is stored in a field in the InfisicalSecret resource. This authentication method can only be used within a Kubernetes environment.
Short-lived service account tokens (Recommended)
1
Create a machine identity
To create an identity, head to your Organization Settings > Access Control > Identities and press Create identity.When creating an identity, you specify an organization level role for it to assume; you can configure roles in Organization Settings > Access Control > Organization Roles.Now input a few details for your new identity. Here’s some guidance for each field:
Name (required): A friendly name for the identity.
Role (required): A role from the Organization Roles tab for the identity to assume. The organization role assigned will determine what organization level resources this identity can have access to.
Once you’ve created an identity, you’ll be prompted to configure the authentication method for it. Here, select Kubernetes Auth.
To learn more about each field of the Kubernetes native authentication method, see step 2 of guide.
2
Add the identity to a project
To allow the operator to use the given identity to access secrets, you will need to add the identity to project(s) that you would like to grant it access to.To do this, head over to the project you want to add the identity to and go to Project Settings > Access Control > Machine Identities and press Add identity.Next, select the identity you want to add to the project and the project level role you want to allow it to assume. The project role assigned will determine what project level resources this identity can have access to.
3
Create a service account
Create a reviewer service account in your Kubernetes cluster. Infisical uses this account to authenticate with the Kubernetes API Server through the TokenReview API.
Bind the service account to the system:auth-delegator cluster role. This allows Infisical to perform delegated authentication checks against the TokenReview API.
Manual long-lived service account tokens are created as Kubernetes secrets and remain valid until deleted or rotated. In most cases, use short-lived service account tokens instead because they are easier to operate and reduce the lifetime of exposed credentials.
1
Create a token reviewer service account
Create a reviewer service account in your Kubernetes cluster. Infisical uses this account to authenticate with the Kubernetes API Server through the TokenReview API.
Bind the reviewer service account to the system:auth-delegator cluster role. This allows Infisical to perform delegated authentication checks against the TokenReview API.
Keep this JWT token handy. You will need it for the Token Reviewer JWT field when configuring Kubernetes Auth on the machine identity in Infisical.
4
Create a machine identity
To create an identity, head to your Organization Settings Access Control Identities and press Create identity.When creating an identity, you specify an organization level role for it to assume; you can configure roles in Organization Settings Access Control Organization Roles.Now input a few details for your new identity. Here’s some guidance for each field:
Name (required): A friendly name for the identity.
Role (required): A role from the Organization Roles tab for the identity to assume. The organization role assigned will determine what organization level resources this identity can have access to.
Once you’ve created an identity, you’ll be prompted to configure the authentication method for it. Here, select Kubernetes Auth.Use the token reviewer JWT from the previous step when filling the Token Reviewer JWT field.
To learn more about each field of the Kubernetes native authentication method, see step 2 of guide.
5
Add the identity to a project
To allow the operator to use the given identity to access secrets, you will need to add the identity to project(s) that you would like to grant it access to.To do this, head over to the project you want to add the identity to and go to Project Settings Access Control Machine Identities and press Add identity.Next, select the identity you want to add to the project and the project level role you want to allow it to assume. The project role assigned will determine what project level resources this identity can have access to.
6
Create the service account used for authentication
Create the Kubernetes service account that the operator will use to authenticate with Infisical.
When to use this option: Choose this approach when you have a gateway deployed in your Kubernetes Cluster and wish to eliminate long-lived tokens. This approach simplifies Infisical Kubernetes Auth configuration, and only one service account will need to have the elevated system:auth-delegator ClusterRole binding.
Note: Gateway is a paid feature. - Infisical Cloud users: Gateway is
available under the Enterprise Tier. - Self-Hosted Infisical: Please
contact sales@infisical.com to purchase an
enterprise license.
Configure the Kubernetes Auth authentication method for the identity
To configure your Kubernetes Auth method to use the gateway as the token reviewer, set the Review Method to “Gateway as Reviewer”, and select the gateway you want to use as the token reviewer.You can select either an individual gateway or a Gateway Pool for automatic failover. When a pool is selected, the platform routes through a healthy gateway at request time. See Gateway Pools for more details.
Once you have set up the Kubernetes Auth prerequisites above, add the identity ID and service account details to your InfisicalSecret resource.
In the authentication.kubernetesAuth.identityId field, add the identity ID of the machine identity you created.
Under authentication.kubernetesAuth.serviceAccountRef, enter the name and namespace of the service account.If using short-lived tokens, set authentication.kubernetesAuth.autoCreateServiceAccountToken to true.
Make sure to also populate the secretsScope field with the project slug
projectSlug, or project ID projectId, environment slug envSlug, and secrets path
secretsPath that you want to fetch secrets from. Please see the examples
below.Please note that you can only use either projectSlug or projectId in the secretsScope field.

from. Please see the example below.
The managed secret properties specify where to store the secrets retrieved from your Infisical project.
This includes defining the name and namespace of the Kubernetes secret that will hold these secrets.
The Infisical operator will automatically create the Kubernetes secret in the specified name/namespace and ensure it stays up-to-date.
The managedSecretReference field is deprecated and will be removed in a future release.
Replace it with managedKubeSecretReferences, which now accepts an array of references to support multiple managed secrets in a single InfisicalSecret CRD.Example:
The name of the managed Kubernetes secret to be created
managedKubeSecretReferences[].secretNamespace
The namespace of the managed Kubernetes secret to be created.
managedKubeSecretReferences[].secretType
Override the default Opaque type for managed secrets with this field. Useful for creating kubernetes.io/dockerconfigjson secrets.
managedKubeSecretReferences[].creationPolicy
Creation policies allow you to control whether or not owner references should be added to the managed Kubernetes secret that is generated by the Infisical operator.
This is useful for tools such as ArgoCD, where every resource requires an owner reference; otherwise, it will be pruned automatically.
Fetching secrets from Infisical as is via the operator may not be enough. This is where templating functionality may be helpful.
Using Go templates, you can format, combine, and create new key-value pairs from secrets fetched from Infisical before storing them as Kubernetes Secrets.
This property controls what secrets are included in your managed secret when using templates.
When set to true, all secrets fetched from your Infisical project will be added into your managed Kubernetes secret resource.
Use this option when you would like to sync all secrets from Infisical to Kubernetes but want to template a subset of them.When set to false, only secrets defined in the managedKubeSecretReferences[].template.data field of the template will be included in the managed secret.
Use this option when you would like to sync only a subset of secrets from Infisical to Kubernetes.
managedKubeSecretReferences[].template.data
Define secret keys and their corresponding templates.
Each data value uses a Golang template with access to all secrets retrieved from the specified scope.Secrets are structured as follows:
type TemplateSecret struct { Value string `json:"value"` SecretPath string `json:"secretPath"`}
managedKubeSecretReferences: - secretName: managed-secret secretNamespace: default template: includeAllSecrets: true data: # Create new secret key that doesn't exist in your Infisical project using values of other secrets NEW_KEY: "{{ .DB_PASSWORD.Value }}" # Override an existing secret key in Infisical project with a new value using values of other secrets API_URL: "https://api.{{.COMPANY_NAME.Value}}.{{.REGION.Value}}.com"
For this example, let’s assume the following secrets exist in your Infisical project:
DB_PASSWORD = "secret123"COMPANY_NAME = "acme"REGION = "us-east-1"API_URL = "old-url" # This will be overridden
The resulting managed Kubernetes secret will then contain:
# Original secrets (from includeAllSecrets: true)DB_PASSWORD = "secret123"COMPANY_NAME = "acme"REGION = "us-east-1"# New and overridden templated secretsNEW_KEY = "secret123" # New secret created from templateAPI_URL = "https://api.acme.us-east-1.com" # Existing secret overridden by template
To help transform your secrets further, the operator provides a set of built-in functions that you can use in your templates.
Extracts all private keys from a PKCS#12 archive and returns them as PKCS#8 PEM-encoded blocks (-----BEGIN PRIVATE KEY-----...).
The archive must not be password-protected — use pkcs12keyPass for password-protected archives.Signature
Extracts all certificates from a PKCS#12 archive and returns them as an ordered PEM chain (-----BEGIN CERTIFICATE-----...).
Sort order: leaf → intermediate(s) → root. If disjunct or multiple leaf certs are provided, they are returned as-is.
The archive must not be password-protected — use pkcs12certPass for password-protected archives.Signature
Takes a PEM-encoded certificate and private key and creates a base64-encoded PKCS#12 archive.
The output is not password-protected — use pemToPkcs12Pass to set a password.Signature
Takes a full PEM-encoded certificate chain (leaf + intermediates + root) and a private key, and creates a base64-encoded PKCS#12 archive that includes the entire chain.
The output is not password-protected — use fullPemToPkcs12Pass to set a password.Signature
Filters PEM blocks by type from a bundle containing multiple PEM blocks (e.g. extract only CERTIFICATE or PRIVATE KEY blocks).
Common PEM types: CERTIFICATE, PRIVATE KEY, PUBLIC KEY, RSA PRIVATE KEY.Signature
Filters PEM certificates by their position in a certificate chain. The chain is automatically ordered before filtering.
Accepted types: leaf (end-entity certificate), intermediate (all intermediate CA certificates), root (root CA certificate).
Returns an empty string if the requested type is not present in the chain.Signature
Takes a JSON-serialized JWK and returns a PEM block of type PRIVATE KEY containing the private key.
Uses x509.MarshalPKCS8PrivateKey internally.Signature
Parses a YAML string into a map[string]any, useful for extracting individual fields from a YAML-formatted secret (e.g. (fromYaml .DB_CONFIG.Value).host returns the host field).Signature
The Infisical Secrets Operator integrates with the Sprig library to provide additional helper functions.
We’ve removed expandEnv and env from the supported functions for security reasons.
managedKubeSecretReferences[].template.metadata
Define custom labels and annotations for the managed Kubernetes secret. This allows you to specify metadata that should be applied to the managed secret separately from the InfisicalSecret itself.For detailed information on how metadata propagation works and examples, see the Propagating Labels & Annotations section.
The managed config map properties specify where to store the secrets retrieved from your Infisical project. Config maps can be used to store non-sensitive data, such as application configuration variables.
The properties includes defining the name and namespace of the Kubernetes config map that will hold the data retrieved from your Infisical project.
The Infisical operator will automatically create the Kubernetes config map in the specified name/namespace and ensure it stays up-to-date. If a config map already exists in the specified namespace, the operator will update the existing config map with the new data.
The usage of config maps is only intended for storing non-sensitive data. If
you are looking to store sensitive data, please use the managed
secret property instead.
managedKubeConfigMapReferences
managedKubeConfigMapReferences[].configMapName
The name of the managed Kubernetes config map that your Infisical data will be stored in.
The namespace of the managed Kubernetes config map that your Infisical data will be stored in.
managedKubeConfigMapReferences[].creationPolicy
Creation policies allow you to control whether or not owner references should be added to the managed Kubernetes config map that is generated by the Infisical operator.
This is useful for tools such as ArgoCD, where every resource requires an owner reference; otherwise, it will be pruned automatically.
Fetching secrets from Infisical as is via the operator may not be enough. This is where templating functionality may be helpful.
Using Go templates, you can format, combine, and create new key-value pairs from secrets fetched from Infisical before storing them as Kubernetes Config Maps.

For this example, let’s assume the following secrets exist in your Infisical project:
SITE_URL = "https://example.com"REGION = "us-east-1"API_URL = "old-url" # This will be overridden
The resulting managed Kubernetes config map will then contain:
# Original config map data (from includeAllSecrets: true)SITE_URL = "https://example.com"REGION = "us-east-1"# New and overridden config map dataSITE_URL = "https://example.com"API_URL = "https://api.example.com.us-east-1.com" # Existing secret overridden by template

Uses x509.MarshalPKCS8PrivateKey internally.Signature
Parses a YAML string into a map[string]any, useful for extracting individual fields from a YAML-formatted secret (e.g. (fromYaml .DB_CONFIG.Value).host returns the host field).Signature
Define custom labels and annotations for the managed Kubernetes ConfigMap. This allows you to specify metadata that should be applied to the managed ConfigMap separately from the InfisicalSecret itself.This field works the same way as template.metadata for managed secrets. For detailed information on how metadata propagation works and examples, see the Propagating Labels & Annotations section.
Once you have configured the InfisicalSecret CRD with the required fields, you can apply it to your cluster.
After applying, you should notice that the managed secret has been created in the desired namespace your specified.
To make use of the managed secret created by the operator into your deployment can be achieved through several methods.
Here, we will highlight three of the most common ways to utilize it. Learn more about Kubernetes secrets here
envFrom
This will take all the secrets from your managed secret and expose them to your container
envFrom: - secretRef: name: managed-secret # managed secret name ``` Example usage in a deployment ```yaml apiVersion: apps/v1kind: Deploymentmetadata: name: nginx-deployment labels: app: nginxspec: replicas: 1 selector: matchLabels: app: nginx template: metadata: labels: app: nginx spec: containers: - name: nginx image: nginx:1.14.2 envFrom: - secretRef: name: managed-secret # <- name of managed secret ports: - containerPort: 80
env
This will allow you to select individual secrets by key name from your managed secret and expose them to your container
env: - name: SECRET_NAME # The environment variable's name which is made available in the container valueFrom: secretKeyRef: name: managed-secret # managed secret name key: SOME_SECRET_KEY # The name of the key which exists in the managed secret
This will allow you to create a volume on your container which comprises of files holding the secrets in your managed kubernetes secret
volumes: - name: secrets-volume-name # The name of the volume under which secrets will be stored secret: secretName: managed-secret # managed secret name
You can then mount this volume to the container’s filesystem so that your deployment can access the files containing the managed secrets
Deployments using managed secrets don’t reload automatically on updates, so they may use outdated secrets unless manually redeployed.
To address this, we added functionality to automatically redeploy your deployment when its managed secret updates.
To enable auto redeployment you simply have to add the following annotation to the Deployment, StatefulSet, or DaemonSet that consumes a managed secret.
How it works When a managed secret is updated, the operator checks for
any Deployments, DaemonSets, or StatefulSets that consume the updated secret
and have the annotation secrets.infisical.com/auto-reload: "true". For each
matching workload, the operator triggers a rolling restart to ensure it picks
up the latest secret values.
To make use of the managed ConfigMap created by the operator into your deployment can be achieved through several methods.

Automatic redeployment of deployments using managed ConfigMaps is not yet
supported.

You can then mount this volume to the container’s filesystem so that your deployment can access the files containing the managed secrets
When you specify template.metadata in your template configuration, you have full control over which labels and annotations are applied to the managed secret:
Labels and annotations from template.metadata are used exclusively on the managed secret
InfisicalSecret labels and annotations are NOT propagated to the managed secret
This allows you to keep InfisicalSecret-specific metadata separate from the managed secret metadata
To prevent any propagation while using template.metadata, pass empty objects for labels and/or annotations.
This will ensure no labels or annotations are propagated to the managed secret, even from the InfisicalSecret CRD’s own labels/annotations:
