Installing CDP Private Cloud Data Services using ECS
Follow the steps in this topic to install CDP Private Cloud Data Services with the Embedded Container Service (ECS).
If your ECS hosts are running the CentOS 8.4, OEL 8.4, or RHEL 8 operating
systems, you must install
iptableson all the ECS hosts. Run the following command on each ECS host:
yum --setopt=tsflags=noscripts install -y iptables
If you are installing ECS on RHEL 8:
- Add the hosts you intend to use for ECS to Cloudera Manager, without specifying a cluster. See Add New Hosts To Cloudera Manager.
If you are using RHEL 8, and if the
nm-cloud-setup.timerservices are enabled, disable them by running the following command on each host you added:
For more information, see Known issues and limitations.
systemctl disable nm-cloud-setup.service nm-cloud-setup.timer
If you disabled the
nm-cloud-setup.timerservices, reboot the added hosts.
In Cloudera Manager, click Data Services in the left
The Add Private Cloud Containerized Cluster page appears. Click Continue.
On the Getting Started page of the installation wizard,
select Internet or Air Gapped as
the Install Method. To use a custom repository link provided to you by Cloudera,
click Custom Repository. Click
Internet install method:
Air Gapped install method:
On the Cluster Basics page, type a name for the Private
Cloud cluster that you want to create in the Cluster Name
field. From the Base Cluster drop-down list, select the
cluster that has the storage and SDX services that
you want this new Private Cloud Data Services instance to connect with. Click
On the Specify Hosts page, provide a list of available
hosts or you can add new hosts. (If you already added the hosts to Cloudera
Manager, enter the Fully Qualified Domain Name (FQDN) for those hosts.) You can
provide the FQDN in the following patterns:
You can specify multiple addresses and address ranges by separating them by commas, semicolons, tabs, or blank spaces, or by placing them on separate lines. Use this technique to make more specific searches instead of searching overly wide ranges.
For example, use host[1-3].network.com to specify these hosts: host1.network.com, host2.network.com, host3.network.com.
On the Select JDK page, select any one from the below
- Manually manage JDK
- Install a Cloudera-provided version of OpenJDK
Install a system-provided version of
On the Enter Login Credentials page, select the
SSH Username and provide the password.
The Install Agents page appears.
On the Assign Roles page, you can customize the roles
assignment for your new Private Cloud Containerized cluster.
Single node ECS installation is supported, but is only intended to enable CDSW to CML migration. If you are installing ECS on a single node, only the Docker and ECS Server roles are assigned. The ECS Agent role is not required for single node installation.
- Configure a Docker
Repository. There are several options for configuring a Docker Repository. For more information about these options, see Docker repository access.On the Configure Docker Repository page, select one of these options:
- Embedded Docker Repository
If you select the Internet Install Method option on the Getting Started page, images are copied over the internet from the Cloudera repository.
If you select the Air Gapped option, images are copied from a local http mirror you have set up in your environment.
Select Default to deploy all of the default Docker images to the repository, or select Select the Optional Images to choose which images to deploy. If you will be deploying Cloudera Machine Learning (CML), toggle the Cloudera Machine Learning switch on to copy the images for CML.
- Cloudera default Docker
RepositoryThis option requires that cluster hosts have access to the internet and you have selected Internet as the install method.
- Ensure that the following ports are opened and allowed. This
is required for completing the ECS installation.
Protocol Port TCP 7180-7192 TCP 19001 TCP 5000 TCP 9000
- Inbound rules for ECS Server nodes.
Protocol Port TCP 9345 TCP 6443 UDP 8472 TCP 10250 TCP 2379 TCP 2380 TCP 30000-32767
- Inbound Rules for ECS Agent.
Protocol Port UDP 4789
- Ensure that the following ports are opened and allowed. This is required for completing the ECS installation.
- Custom Docker Repository
This option requires that you set up a Docker Repository in your environment and that all cluster hosts have connectivity to the repository.You must enter the following options:Click the Generate the copy-docker script button to generate and download a script that copies the Docker images from Cloudera, or (for air-gapped installation) from a local http mirror in your network.
Run the script from a machine that is running Docker locally and has access to the Docker images using the following commands:
- Custom Docker Repository – Enter the URL for your Docker Repository
- Docker Username – Enter the username for the Docker Repository.
- Docker Password – Enter the password for the Docker Repository.
- Docker Certificate – Click the Choose File button to upload a TLS certificate to secure communications with the Docker Repository.
docker login [***URL for Docker Repository***] -u [***username of user with write access***] bash copy-docker.txt
The copying operation may take 4 - 5 hours.
- Embedded Docker Repository
On the Configure Data Services page, you can modify
configuration settings such as the data storage directory, number of replicas,
and so on. If there are multiple disks mounted on each host with different
characteristics (HDD and SSD), then Local Path Storage Directory must point to
the path belonging to the optimal storage. Ensure that you have reviewed your
changes. If you want to specify a custom certificate, place the certificate and
the private key in a specific location on the Cloudera Manager server host and
specify the paths in the input boxes labelled as Ingress Controller TLS/SSL
Server Certificate/Private Key File below. This certificate will be copied to
the Control Plane during the installation process.
On the Configure Databases page, follow the instructions
in the wizard to use your external existing databases with CDP Private
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). Enabling the Private Cloud Base Cluster PostgreSQL database to use an SSL connection to encrypt client-server communication is a requirement for CDW in CDP Private Cloud.
On the Install Parcels page, the selected parcels are
downloaded and installed on the host cluster. Click
On the Inspect Cluster page, you can inspect your
network performance and hosts. If the inspect tool displays any issues, you can
fix those issues and run the inspect tool again.
The installation progress is displayed on the Install Data
When the installation is complete, you will see the
Summary image. You can now launch CDP Private
- When the installation is complete, you can access your Private Cloud Data Services instance from Cloudera Manager. Click Data Services, then click Open Private Cloud Data Services for the applicable Data Services cluster.
If the installation fails, and you see the following error message in the stderr output during the Install Longhorn UI step, retry the installation by clicking the Resume button.
++ openssl passwd -stdin -apr1 + echo 'cm-longhorn:$apr1$gp2nrbtq$1KYPGI0QNlFJ2lo5sV62l0' + kubectl -n longhorn-system create secret generic basic-auth --from-file=auth + rm -f auth + kubectl -n longhorn-system apply -f /opt/cloudera/cm-agent/service/ecs/longhorn-ingress.yaml Error from server (InternalError): error when creating "/opt/cloudera/cm-agent/service/ecs/longhorn-ingress.yaml": Internal error occurred: failed calling webhook "validate.nginx.ingress.kubernetes.io": Post "https://rke2-ingress-nginx-controller-admission.kube-system.svc:443/networking/v1/ingresses?timeout=10s": x509: certificate signed by unknown authority
- If you specified a custom certificate, select the ECS cluster in Cloudera
Manager, then select Actions > Update Ingress Controller.
This command copies the
key.pemfiles from the Cloudera Manager server host to the ECS Management Console host.
- Click Open Private Cloud Data Services to launch your CDP Private Cloud Data Services instance.
- Log in using the default username and password admin.
- 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 are able to connect to the configured LDAP server.
- Create your first Virtual Warehouse in the CDW Data Service
- Provision an ML Workspace in the CML Data Service
- Add a CDE service in the CDE Data Service
