Installing in air gap environment
You can launch the Private Cloud installation wizard from Cloudera Manager and follow the steps to install CDP Private Cloud Data Services in an air gap environment where your Cloudera Manager instance or your Kubernetes cluster does not have access to the Internet.
- Ensure that your Kubernetes
kubeconfighas permissions to create Kubernetes namespaces.
- You require persistent storage classes defined in your OpenShift cluster. Storage classes can be defined by OpenShift cluster administrators.
- Only TLS-enabled custom Docker Registry is supported. Ensure that you use a TLS certificate to secure the custom Docker Registry. The TLS certificate can be self-signed, or signed by a private or public trusted Certificate Authority (CA).
- Only TLS 1.2 is supported for authentication with Active Directory/LDAP. You require TLS 1.2 to authenticate the CDP control plane with your LDAP directory service like Active Directory.
In Cloudera Manager, on the top right corner, click Add
> Add Cluster. The Select Cluster
Type page appears.
In the Select Cluster Type page, select the cluster type
as Private Cloud Containerized Cluster and under
Other Options dropdown, click
here to install CDP Private Cloud Data Services.
On the Getting Started page of the installation wizard,
select Air Gapped as the Install Method. If you wish to
use a custom repository link provided to you by Cloudera, click
Custom Repository. On the Getting
Started page of the installation wizard, you can select the
repository that contains the installer. The Select
Repository field contains the CDP Private Cloud Data Services
repository download link. To use a custom repository link provided to you by
Cloudera, click Custom Repository. Click Continue.
In the Configure Docker Repository page, you must select
one of the Docker repository options. If you select Use a custom
Docker Repository option, then enter your local Docker
Repository in the Custom Docker Repository field in the following
format:[*DOCKER REGISTRY*]/[*REPOSITORY NAME*].
Alternatively, you can use Cloudera's default Docker Repository if you are
setting up CDP Private Cloud in non-production environments.
You can follow these steps to prepare your Docker Repository from a machine that is running Docker locally and has access to all the Docker images either directly from Cloudera or a local HTTP mirror in your network.
If you select Use an embedded Docker Repository option, then you can download and deploy the Data Services that you need for your cluster.
- Click Generate the copy-docker script on the wizard or download the script file.
Log in to your custom Docker Registry and run the script using the
docker login <your_custom_registry> -u <user_with_write_access> bash copy-docker.txt
- Enter your Docker user name and password.
- Click Choose File to upload your Docker certificate.
- By selecting Default, all the data services will be downloaded and deployed.
- By selecting Select the optional images:
- If you switch off the Machine Learning toggle key, then the Machine Learning runtimes will not be installed.
- If you switch on the Machine Learning toggle key, then the Machine Learning runtimes will be installed.
In the Configure Databases page, follow the instructions
in the wizard to use your external existing databases with CDP Private
For production environments, Cloudera recommends that you use databases that you have previously created. These databases must all be on the same host and that host must be a PostgreSQL database server running version 10 or 12.
Ensure that you have selected the Use TLS for Connections Between the Control Plane and the Database option if you have plans to use Cloudera Data Warehouse (CDW) Private Cloud. Enabling the base cluster PostgreSQL database to use an SSL connection to encrypt client-server communication is a requirement for CDW in CDP Private Cloud.
The databases must be created before you can proceed with the installation, and the database user must have permissions to create and drop databases on the server.
To create an embedded database, select Create embedded databases option.
To use an existing database, select Use existing databases (Recommended for production) option.
In the Configure Kubernetes page, enter your Kubernetes,
Docker, database, and vault information.
- Upload a Kubernetes configuration (kubeconfig) file from your existing environment. You can obtain this file from your OpenShift Container Platform administrator. Ensure that this kubeconfig has permissions to create Kubernetes namespaces.
- In the Kubernetes Namespace field, enter the Kubernetes namespace that you want to use with this CDP Private Cloud deployment. Kubernetes virtual clusters are called namespaces. For more information, see Kubernetes namespaces
- Enter your Vault information and upload a CA certificate. Cloudera recommends that you use an external Vault for production environments. Enter the Vault address and token, and upload a CA certificate.
- Enter a Storage Class to be configured on the Kubernetes cluster. CDP Private Cloud uses Persistent Volumes to provision storage. You can leave this field empty if you have a default storage class configured on your Openshift cluster. Click Continue.
If you want to use this installation configuration again to install CDP Private
Cloud, you have the option to download this information as a template.
The template file is a text file that contains the database and vault information that you entered for this installation. This template is useful if you will be installing Private Cloud again with the same databases, as the template will populate the fields here automatically. Note that the user password information is not saved in the template.
The Installation Progress page appears. Click
The summary message with a link to Launch CDP
- Click Launch CDP to launch your CDP Private Cloud Data Services.
- Log in using the default user name and password
- In the Welcome to CDP Private Cloud page, click Change Password to change the Local Administrator Account password.
- Set up external authentication using the URL of the LDAP server and a CA certificate of your secure LDAP. Follow the instructions on the Welcome to CDP Private Cloud page to complete this step.
- Click Test Connection to ensure that you can connect to the configured LDAP server.
- Register a CDP Private Cloud Data Services environment.
- Create your first Virtual Warehouse in the CDW Data Services and/or Provision an ML Workspace in the CML Data Services.
