Custom Resource Definitions

As part of Okteto's installation, several Custom Resource Definitions (CRDs) are installed in your cluster. These CRDs primarily store different types of information necessary for Okteto's functionality. You can view the list of Okteto's CRDs by exploring the crds folder in the templates of the Okteto Helm Chart or by running the following command:

kubectl get crd | grep okteto.com

You can let Okteto install these CRDs or you can choose to install them manually, but be aware they are needed for Okteto to work properly. You can use the following configuration setting to let Okteto know if it should install them or not. By default, Okteto will install them.

Private Registries​

Private registry configurations can be managed either through the Admin dashboard or by using one of Okteto’s installed CRDs: admin.okteto.com. This last case is useful, for example, if you have your own mechanism to provision credentials/secrets in your cluster.

There are 3 types of registries you can configure: Static credentials, AWS IAM User, and AWS IAM Role.

Static Credentials​

To define your private registries with static credentials using CRDs, you must first create an Opaque Kubernetes secret containing the necessary data to access your private registry. This secret should include both the username and password for accessing the registry.

Once the secret is created, you will need to create a resource with the apiVersion: admin.okteto.com/v1 and Registry kind, which is one of the CRDs installed by Okteto, referring to the secret which contains the credentials.

The name of this new resource should be the hostname of the registry (e.g. index.docker.io). For example, if you want to add a configuration for Docker's registry, you will need to create a resource like this:

note

Defining the port through spec.static.port is optional and only available for static registries. It should only be used if the registry listens on a port other than the default http(s) 80/443

apiVersion: admin.okteto.com/v1
kind: Registry
metadata:
  name: index.docker.io # hostname of the registry to be configured
  namespace: okteto
spec:
  static:
    port: 5000 # optional
    passwordSecretRef:
      key: <field in referenced secret> # key of the secret which contains the password
      name: <secret-name> # name of the secret where the password is stored
    userSecretRef:
      key: <field in referenced secret> # key of the secret which contains the username
      name: <secret-name> # name of the secret where the username is stored

AWS IAM User​

In the case of AWS IAM User, where you have to specify the Access Key and Access Secret, the process is similar to the static credentials CRD. For AWS IAM User credentials (Access Key and Secret Access Key), the process is similar to configuring static credentials. First, create a secret containing the Access Key and Secret Access Key values. Then, create a CRD like this (the name of the resource has to be the hostname of the registry to be configured and it has to end with .amazonaws.com, e.g. 111122223333.dkr.ecr.eu-central-1.amazonaws.com):

apiVersion: admin.okteto.com/v1
kind: Registry
metadata:
  name: 111122223333.dkr.ecr.eu-central-1.amazonaws.com # hostname of the registry to be configured
  namespace: okteto
spec:
  awsIamUser:
    accessKeyIDSecretRef:
      key: <field in referenced secret> # key of the secret which contains the access key
      name: <secret-name> # name of the secret where the access key is stored
    secretAccessKeySecretRef:
      key: <field in referenced secret> # key of the secret which contains the access secret key
      name: <secret-name> # name of the secret where the access secret is stored

You can find more information here about how to obtain the values to use.

AWS IAM Role​

In this case, the process is a bit simpler. It doesn't require a secret, as it doesn't store sensitive information. So, you will only need to create a CRD like the following one specifying the registry hostname as the resource name (it has to end with .amazonaws.com, e.g. 111122223333.dkr.ecr.eu-central-1.amazonaws.com):

apiVersion: admin.okteto.com/v1
kind: Registry
metadata:
  name: 111122223333.dkr.ecr.eu-central-1.amazonaws.com # hostname of the registry to be configured
  namespace: okteto
spec:
  awsIamRole:
    audience: okteto.example.com/us-east-2 # Audience used to exchange token to access the registry
    roleARN: arn:aws:iam::112233445566:role/my-private-registry # ARN role with the permissions needed to access to the registry

You can find more information here about how to obtain the values to use.

Catalog Items​

Catalog items are typically managed via the Admin dashboard, but can also be managed via one of the CRDs installed by Okteto: catalogitems.git.okteto.com. This approach is useful if you want to add catalog items manually with kubectl commands or manage your catalog using GitOps.

note

If you add Catalog items using CRDs they will be displayed in the UI, but they can't be modified from the UI. If you want to manage them from the UI, they must be created from there.

To configure a catalog item, create a resource like this:

  • metadata.name: name of the CatalogItem resource to be created
  • spec.branch: default branch for the CatalogItem. (optional)
  • spec.manifestPath: path to the manifest file in the repository (optional)
  • spec.name: Display name in the Catalog UI list
  • spec.repositoryUrl: URL of the repository
  • spec.variables: list of variables suggested to the user at deployment time. Each variable can be defined by name only, or by name and value (optional)
my-catalog-item.yaml
apiVersion: git.okteto.com/v1
kind: CatalogItem
metadata:
  name: my-catalog-item
  namespace: okteto
spec:
  branch: ""
  manifestPath: ""
  name: my-catalog-item
  repositoryUrl: https://github.com/okteto/movies-with-helm
  variables:
    - name: VARIABLE_WITH_VALUE
      value: my-value
    - name: VARIABLE_WITHOUT_VALUE

To apply the changes manually, run the command kubectl apply -f my-catalog-item.yaml from your terminal to add the catalog item to the your Catalog in the cluster.

Cloud Credentials​

Cloud Credentials are mainly managed via the Admin dashboard, but can also be managed via one of the CRDs installed by Okteto: dynamicconfigs.admin.okteto.com. Using CRDs can be useful if you would like to add Cloud Credentials manually with a simple kubectl command or manage your Cloud Credentials using GitOps.

note

If you add credentials using CRDs they will be displayed in the UI, but they can't be modified from the UI. If you want to manage them from the UI, they must be created from there.

For example, if you want to add a configuration for GCP Cloud Credential, you will need to create a resource like this:

  • metadata.name: gcp-credentials-config
  • spec.audience: This is the intended audience for the credential. It is typically a URL or a string that identifies the target service or application that will use the credential.
  • spec.projectNumber: This is the unique identifier for your Google Cloud project. It is a numeric value that is assigned to your project when you create it in the Google Cloud Console.
  • spec.providerId: his is the identifier for the identity provider. It is used to specify which identity provider will be used to authenticate the credentials.
  • spec.workloadIdentityPoolId: This is the identifier for the Workload Identity Pool. It is used to specify the pool of identities that can be used to authenticate the credentials.
gcp-cloud-credential.yaml
apiVersion: admin.okteto.com/v1
kind: DynamicConfig
metadata:
  name: gcp-credentials-config
  namespace: okteto
 spec:
  audience: <audience>
  projectNumber: <project-number>
  providerId: <provider-id>
  workloadIdentityPoolId: <workload-identity-pool-id>

Alternatively, if you would like to add a configuration for AWS Cloud Credentials, you will need to create a resource like this:

  • metadata.name: aws-credentials-config
  • spec.audience: This is the intended audience for the credential. It is typically a URL or a string that identifies the target service or application that will use the credential.
  • spec.region: This specifies the AWS region where the credentials will be used. It is a string that identifies the geographic area where AWS resources are located.
  • spec.roleARN: This is the Amazon Resource Name (ARN) of the IAM role that will be assumed. It uniquely identifies the role within AWS and is used to specify which role will be used to authenticate the credentials.
aws-cloud-credential.yaml
apiVersion: admin.okteto.com/v1
kind: DynamicConfig
metadata:
  name: aws-credentials-config
  namespace: okteto
spec:
  audience: <audience>
  region: <region>
  roleARN: <roleARN>

To apply the changes manually, run the command kubectl apply -f aws-cloud-credential.yaml from your terminal to add the catalog item to the your Cloud Credential to the cluster.

note

Each cloud provider credential configuration in Okteto must use a specific name: gcp-credentials-config for Google Cloud Platform and aws-credentials-config for Amazon Web Services. Only one credential configuration is allowed per provider, meaning you can define one for GCP and one for AWS, but no more than one for each.
