InfisicalSecret CRD properties

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.

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.

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.

Create a machine identity

You need to create a machine identity, and give it access to the project(s) you want to interact with. You can read more about machine identities here.

Create Kubernetes secret containing machine identity 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.

  kubectl create secret generic universal-auth-credentials --from-literal=clientId="<your-identity-client-id>" --from-literal=clientSecret="<your-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.

Example

apiVersion: secrets.infisical.com/v1alpha1
kind: InfisicalSecret
metadata:
  name: infisicalsecret-sample-crd
spec:
  authentication:
      universalAuth:
          secretsScope:
              projectSlug: <project-slug> # <-- project slug
              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
  ...

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.

Obtaining the token reviewer JWT for Infisical

1.1. Start by creating a service account in your Kubernetes cluster that will be used by Infisical to authenticate with the Kubernetes API Server.

infisical-service-account.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
  name: infisical-auth
  namespace: default

kubectl apply -f infisical-service-account.yaml

1.2. Bind the service account to the system:auth-delegator cluster role. As described here, this role allows delegated authentication and authorization checks, specifically for Infisical to access the TokenReview API. You can apply the following configuration file:

cluster-role-binding.yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: role-tokenreview-binding
  namespace: default
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: system:auth-delegator
subjects:
  - kind: ServiceAccount
    name: infisical-auth
    namespace: default

kubectl apply -f cluster-role-binding.yaml

1.3. Next, create a long-lived service account JWT token (i.e. the token reviewer JWT token) for the service account using this configuration file for a new Secret resource:

service-account-token.yaml
apiVersion: v1
kind: Secret
type: kubernetes.io/service-account-token
metadata:
  name: infisical-auth-token
  annotations:
    kubernetes.io/service-account.name: "infisical-auth"

kubectl apply -f service-account-token.yaml

1.4. Link the secret in step 1.3 to the service account in step 1.1:

kubectl patch serviceaccount infisical-auth -p '{"secrets": [{"name": "infisical-auth-token"}]}' -n default

1.5. Finally, retrieve the token reviewer JWT token from the secret.

kubectl get secret infisical-auth-token -n default -o=jsonpath='{.data.token}' | base64 --decode

Keep this JWT token handy as you will need it for the Token Reviewer JWT field when configuring the Kubernetes Auth authentication method for the identity in step 2.

Creating an identity

To create an identity, head to your Organization Settings > Access Control > Machine 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.

Adding an 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.

Add your identity ID & service account to your InfisicalSecret resource

Once you have created your machine identity and added it to your project(s), you will need to add the identity ID to your InfisicalSecret resource. In the authentication.kubernetesAuth.identityId field, add the identity ID of the machine identity you created. See the example below for more details.

Add your Kubernetes service account token to the InfisicalSecret resource

Add the service account details from the previous steps under authentication.kubernetesAuth.serviceAccountRef. Here you will need to enter the name and namespace of the service account. The example below shows a complete InfisicalSecret resource with all required fields defined.

Example

example-kubernetes-auth.yaml
apiVersion: secrets.infisical.com/v1alpha1
kind: InfisicalSecret
metadata:
  name: infisicalsecret-sample-crd
spec:
  authentication:
      kubernetesAuth:
          identityId: <machine-identity-id>
          serviceAccountRef:
            name: <service-account-name>
            namespace: <service-account-namespace>

          # secretsScope is identical to the secrets scope in the universalAuth field in this sample.
          secretsScope:
              projectSlug: your-project-slug
              envSlug: prod
              secretsPath: "/path"
              recursive: true
  ...

The AWS IAM 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 an AWS environment like an EC2 or a Lambda function.

The service token required to authenticate with Infisical needs to be stored in a Kubernetes secret. This block defines the reference to the name and namespace of secret that stores this service token. Follow the instructions below to create and store the service token in a Kubernetes secrets and reference it in your CRD.

1. Generate service token

You can generate a service token for an Infisical project by heading over to the Infisical dashboard then to Project Settings.

2. Create Kubernetes secret containing service token

Once you have generated the service token, you will need to create a Kubernetes secret containing the service token you generated. To quickly create a Kubernetes secret containing the generated service token, you can run the command below. Make sure you replace <your-service-token-here> with your service token.

kubectl create secret generic service-token --from-literal=infisicalToken="<your-service-token-here>"

3. Add reference for the Kubernetes secret containing service token

Once the secret is created, add the name and namespace of the secret that was just created under authentication.serviceToken.serviceTokenSecretReference field in the InfisicalSecret resource.

Make sure to also populate the secretsScope field with the, environment slug envSlug, and secrets path secretsPath that you want to fetch secrets from. Please see the example below.

Example

apiVersion: secrets.infisical.com/v1alpha1
kind: InfisicalSecret
metadata:
  name: infisicalsecret-sample-crd
spec:
  authentication:
    serviceToken:
      serviceTokenSecretReference:
        secretName: service-token # <-- name of the Kubernetes secret that stores our service token
        secretNamespace: option # <-- namespace of the Kubernetes secret that stores our service token
      secretsScope:
        envSlug: <env-slug> # "dev", "staging", "prod", etc..
        secretsPath: <secrets-path> # Root is "/"
  ...

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"`
}

Example template configuration:

  managedSecretReference:
    secretName: managed-secret
    secretNamespace: default
    template:
      includeAllSecrets: true
      data:
        NEW_KEY: "{{ .KEY1.SecretPath }} {{ .KEY1.Value }}"

When you run the following command:

kubectl get secret managed-secret -o jsonpath='{.data}'

You’ll receive Kubernetes secrets output that includes the NEW_KEY:

{... "KEY":"d29ybGQ=","NEW_KEY":"LyBoZWxsbw=="}

When you set includeAllSecrets as false the Kubernetes secrets outputs will be:

{"NEW_KEY":"LyBoZWxsbw=="}

Apply the InfisicalSecret CRD to your cluster

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.

kubectl apply -f example-infisical-secret-crd.yaml

Verify managed secret creation

To verify that the operator has successfully created the managed secret, you can check the secrets in the namespace that was specified.

# Verify managed secret is created
kubectl get secrets -n <namespace of managed secret>

The Infisical secrets will be synced and stored into the managed secret every 1 minutes.

Using managed secret in your deployment

Incorporating 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

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/v1
kind: Deployment
metadata:
  name: nginx-deployment
  labels:
    app: nginx
spec:
  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

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

Example usage in a deployment

apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
labels:
app: nginx
spec:
replicas: 1
selector:
matchLabels:
app: nginx
template:
metadata:
labels:
app: nginx
spec:
containers: - name: nginx
image: nginx:1.14.2
env: - name: STRIPE_API_SECRET
valueFrom:
secretKeyRef:
name: managed-secret # <- name of managed secret
key: STRIPE_API_SECRET
ports: - containerPort: 80

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

volumeMounts:
  - name: secrets-volume-name
    mountPath: /etc/secrets
    readOnly: true

Example usage in a deployment

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  labels:
    app: nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
        - name: nginx
          image: nginx:1.14.2
          volumeMounts:
            - name: secrets-volume-name
              mountPath: /etc/secrets
              readOnly: true
          ports:
            - containerPort: 80
      volumes:
        - name: secrets-volume-name
          secret:
            secretName: managed-secret # <- managed secrets

The definition file of the Kubernetes secret for the CA certificate can be structured like the following:

apiVersion: v1
kind: Secret
metadata:
  name: custom-ca-certificate
type: Opaque
stringData:
  ca.crt: |
    -----BEGIN CERTIFICATE-----
    MIIEZzCCA0+gAwIBAgIUDk9+HZcMHppiNy0TvoBg8/aMEqIwDQYJKoZIhvcNAQEL
    ...
    BQAwDTELMAkGA1UEChMCUEgwHhcNMjQxMDI1MTU0MjAzWhcNMjUxMDI1MjE0MjAz
    -----END CERTIFICATE-----

Auto redeployment

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.

Enabling auto redeploy

To enable auto redeployment you simply have to add the following annotation to the deployment that consumes a managed secret

secrets.infisical.com/auto-reload: "true"

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  labels:
    app: nginx
  annotations: 
    secrets.infisical.com/auto-reload: "true" # <- redeployment annotation
spec:
  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
        ports:
        - containerPort: 80

How it works

When a secret change occurs, the operator will check to see which deployments are using the operator-managed Kubernetes secret that received the update. Then, for each deployment that has this annotation present, a rolling update will be triggered.

Propagating labels & annotations

The operator will transfer all labels & annotations present on the InfisicalSecret CRD to the managed Kubernetes secret to be created. Thus, if a specific label is required on the resulting secret, it can be applied as demonstrated in the following example:

apiVersion: secrets.infisical.com/v1alpha1
kind: InfisicalSecret
metadata:
  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:
  ..
  authentication:
    ...
  managedSecretReference:
    ...

This would result in the following managed secret to be created:

apiVersion: v1
data: ...
kind: Secret
metadata:
  annotations:
    example.com/annotation-to-be-passed-to-managed-secret: sample-value
    secrets.infisical.com/version: W/"3f1-ZyOSsrCLGSkAhhCkY2USPu2ivRw"
  labels:
    label-to-be-passed-to-managed-secret: sample-value
  name: managed-token
  namespace: default
type: Opaque
