Using the InfisicalPushSecret CRD

Learn how to use the InfisicalPushSecret CRD to push and manage secrets in Infisical.

Overview

The InfisicalPushSecret CRD allows you to create secrets in your Kubernetes cluster and push them to Infisical.

This CRD offers the following features:

• Push Secrets from a Kubernetes secret into Infisical.
• Manage secret lifecycle of pushed secrets in Infisical. When the Kubernetes secret is updated, the operator will automatically update the secrets in Infisical. Optionally, when the Kubernetes secret is deleted, the operator will delete the secrets in Infisical automatically.

Prerequisites

• A project within Infisical.
• A machine identity ready for use in Infisical that has permissions to create secrets in your project.
• The operator is installed on to your Kubernetes cluster.

Example usage

Below is a sample InfisicalPushSecret CRD that pushes secrets defined in a Kubernetes secret to Infisical.

After filling out the fields in the InfisicalPushSecret CRD, you can apply it directly to your cluster.

Before applying the InfisicalPushSecret CRD, you need to create a Kubernetes secret containing the secrets you want to push to Infisical. An example can be seen below the InfisicalPushSecret CRD.

infisical-push-secret.yaml

  apiVersion: secrets.infisical.com/v1alpha1
  kind: InfisicalPushSecret
  metadata:
    name: infisical-push-secret-demo
  spec:
    resyncInterval: 1m # Remove this field to disable automatic reconciliation of the InfisicalPushSecret CRD.
    hostAPI: https://app.infisical.com/api

    # Optional, defaults to no replacement.
    updatePolicy: Replace # If set to replace, existing secrets inside Infisical will be replaced by the value of the PushSecret on sync.

    # Optional, defaults to no deletion.
    deletionPolicy: Delete # If set to delete, the secret(s) inside Infisical managed by the operator, will be deleted if the InfisicalPushSecret CRD is deleted.

    destination:
      projectId: <project-id> # Either projectId or projectSlug is required
      projectSlug: <project-slug>
      environmentSlug: <env-slug>
      secretsPath: <secret-path>

    push:
      secret:
        secretName: push-secret-demo # Secret CRD
        secretNamespace: default

    # Only have one authentication method defined or you are likely to run into authentication issues.
    # Remove all except one authentication method.
    authentication:
      awsIamAuth:
        identityId: <machine-identity-id>
      azureAuth:
        identityId: <machine-identity-id>
      gcpIamAuth:
        identityId: <machine-identity-id>
        serviceAccountKeyFilePath: </path-to-service-account-key-file.json>
      gcpIdTokenAuth:
        identityId: <machine-identity-id>
      kubernetesAuth:
        identityId: <machine-identity-id>
        serviceAccountRef:
          name: <secret-name>
          namespace: <secret-namespace>
      ldapAuth:
        identityId: <machine-identity-id>
        credentialsRef:
          secretName: <secret-name> # ldap-auth-credentials
          secretNamespace: <secret-namespace> # default
      universalAuth:
        credentialsRef:
          secretName: <secret-name> # universal-auth-credentials
          secretNamespace: <secret-namespace> # default

source-secret.yaml

  apiVersion: v1
  kind: Secret
  metadata:
    name: push-secret-demo
    namespace: default
  stringData: # can also be "data", but needs to be base64 encoded
    API_KEY: some-api-key
    DATABASE_URL: postgres://127.0.0.1:5432
    ENCRYPTION_KEY: fabcc12-a22-facbaa4-11aa568aab

  kubectl apply -f source-secret.yaml

After applying the soruce-secret.yaml file, you are ready to apply the InfisicalPushSecret CRD.

  kubectl apply -f infisical-push-secret.yaml

After applying the InfisicalPushSecret CRD, you should notice that the secrets you have defined in your source-secret.yaml file have been pushed to your specified destination in Infisical.

InfisicalPushSecret CRD properties

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/api

When 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:

http://<backend-svc-name>.<namespace>.svc.cluster.local:4000/api

Make sure to replace <backend-svc-name> and <namespace> with the appropriate values for your backend service and namespace.

resyncInterval

The resyncInterval is a string-formatted duration that defines the time between each resync. The field is optional, and will default to no automatic resync if not defined.

If you don’t want to automatically reconcile the InfisicalPushSecret CRD on an interval, you can remove the resyncInterval field entirely from your InfisicalPushSecret CRD.

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).

Valid intervals examples:

resyncInterval: 5s # 10 seconds
resyncInterval: 10s # 10 seconds
resyncInterval: 5m # 5 minutes
resyncInterval: 1h # 1 hour
resyncInterval: 1d # 1 day

updatePolicy

The field is optional and will default to None if not defined.

The update policy defines how the operator should handle conflicting secrets when pushing secrets to Infisical.

Valid values are None and Replace.

Behavior of each policy:

• None: The operator will not override existing secrets in Infisical. If a secret with the same key already exists, the operator will skip pushing that secret, and the secret will not be managed by the operator.
• Replace: The operator will replace existing secrets in Infisical with the new secrets. If a secret with the same key already exists, the operator will update the secret with the new value.

spec:
  updatePolicy: Replace

deletionPolicy

This field is optional and will default to None if not defined.

The deletion policy defines what the operator should do in case the InfisicalPushSecret CRD is deleted.

Valid values are None and Delete.

Behavior of each policy:

• None: The operator will not delete the secrets in Infisical when the InfisicalPushSecret CRD is deleted.
• Delete: The operator will delete the secrets in Infisical that are managed by the operator when the InfisicalPushSecret CRD is deleted.

spec:
  deletionPolicy: Delete

destination

The destination field is used to specify where you want to create the secrets in Infisical. The required fields are projectId, environmentSlug, and secretsPath.

spec:
  destination:
    projectId: <project-id>
    environmentSlug: <env-slug>
    secretsPath: <secrets-path>

destination.projectId

The project ID where you want to create the secrets in Infisical.

Please note that you can only use either projectId or projectSlug in the destination field.

Using templating to push secrets

Pushing secrets to Infisical from the operator may not always be enough. Templating is a useful utility of the Infisical secrets operator that allows you to use Go Templating to template the secrets you want to push to Infisical. Using Go templates, you can format, combine, and create new key-value pairs of secrets that you want to push to Infisical.

push.secret.template

push.secret.template.includeAllSecrets

This property controls what secrets are included in your push to Infisica. When set to true, all secrets included in the push.secret.secretName Kubernetes secret will be pushed to Infisical. Use this option when you would like to push all secrets to Infisical from the secrets operator, but want to template a subset of them.

When set to false, only secrets defined in the push.secret.template.data field of the template will be pushed to Infisical. Use this option when you would like to push only a subset of secrets from the Kubernetes secret to Infisical.

push.secret.template.data

Define secret keys and their corresponding templates. Each data value uses a Golang template with access to all secrets defined in the push.secret.secretName Kubernetes secret.

Secrets are structured as follows:

type TemplateSecret struct {
    Value      string `json:"value"`
    SecretPath string `json:"secretPath"`
}

Example template configuration:

# This example assumes that the `push-secret-demo` Kubernetes secret contains the following secrets:
# SITE_URL = "https://example.com"
# REGION = "us-east-1"
# OTHER_SECRET = "other-secret"

push:
  secret:
    secretName: push-secret-demo
    secretNamespace: default
    template:
      includeAllSecrets: true # Includes all secrets from the `push-secret-demo` Kubernetes secret
      data:
        SITE_URL: "{{ .SITE_URL.Value }}"
        API_URL: "https://api.{{.SITE_URL.Value}}.{{.REGION.Value}}.com" # Will create a new secret in Infisical with the key `API_URL` with the value of the `SITE_URL` and `REGION` secrets

To help transform your config map data further, the operator provides a set of built-in functions that you can use in your templates.

Available templating functions

Please refer to the templating functions documentation for more information.

Using generators to push secrets

Generators allow secrets to be dynamically generated during each reconciliation cycle and then pushed to Infisical. They are useful for use cases where a new secret value is needed on every sync, such as ephemeral credentials or one-time-use tokens.

A generator is defined as a custom resource (ClusterGenerator) within the cluster, which specifies the logic for generating secret values. Generators are stateless, each invocation triggers the creation of a new set of values, with no tracking or persistence of previously generated data.

Because of this behavior, you may want to disable automatic syncing for the InfisicalPushSecret resource to avoid continuous regeneration of secrets. This can be done by omitting the resyncInterval field from the InfisicalPushSecret CRD.

Example usage

  push:
    secret:
      secretName: push-secret-source-secret
      secretNamespace: dev
    generators:
      - destinationSecretName: password-generator # Name of the secret that will be created in Infisical
        generatorRef:
          kind: Password # Kind of the resource, must match the generator kind.
          name: custom-generator # Name of the generator resource

To use a generator, you must specify at least one generator in the push.generators[] field.

push.generators[]

This field holds an array of the generators you want to use for your InfisicalPushSecret CRD.

push.generators[].destinationSecretName

The name of the secret that will be created in Infisical.

push.generators[].generatorRef

The reference to the generator resource.

Valid fields:

• kind: The kind of the generator resource, must match the generator kind.
• name: The name of the generator resource.

push.generators[].generatorRef.kind

The kind of the generator resource, must match the generator kind.

Valid values:

• Password
• UUID

push.generators[].generatorRef.name

The name of the generator resource.
