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, RHEL 7.9, or RHEL 8 operating systems, you must install iptables on all the ECS hosts.
For CentOS 8.4, OEL 8.4, or RHEL 8, run the following command on each ECS host:
```
yum --setopt=tsflags=noscripts install -y iptables
```
For RHEL 7.9, run the following command on each ECS host:
```
yum install -y iptables
```
If you are installing ECS on RHEL 8:
1. Add the hosts you intend to use for ECS to Cloudera Manager, without specifying a cluster. See Add New Hosts To Cloudera Manager.
2. If you are using RHEL 8, and if the nm-cloud-setup.service and nm-cloud-setup.timer services are enabled, disable them by running the following command on each host you added:
```
systemctl disable nm-cloud-setup.service nm-cloud-setup.timer
```
  For more information, see Known issues and limitations.
3. If you disabled the nm-cloud-setup.service and nm-cloud-setup.timer services, reboot the added hosts.
In Cloudera Manager, click Data Services in the left menu.

The Add Private Cloud Containerized Cluster page appears. Click Continue.

note
You can also click Add > Add Cluster at the top right in Cloudera Manager, then select Private Cloud Containerized Cluster as the cluster type.
On the Getting Started page of the installation wizard, select Internet or Air Gapped as the Install Method.

Internet install method (To use a custom repository link provided to you by Cloudera, click Custom Repository) :
If you select the Air Gapped install option, extra steps are displayed. Follow these steps to download and mirror the Cloudera archive URL using a local HTTP server.
1. Download everything under https://archive.cloudera.com/p/cdp-pvc-ds/latest
```
wget -l 0 --recursive --no-parent -e robots=off -nH --cut-dirs=2 --reject="index.html*" -t 10 https://<username>:<password>@archive.cloudera.com/p/cdp-pvc-ds/latest
```
2. Edit the manifest.json file in the downloaded directory. Change "http_url": "..." to
  
  "http_url": "http://your_local_repo/cdp-pvc-ds/latest"
3. Mirror the downloaded directory to your local http server, e.g. http://your_local_repo/cdp-pvc-ds/latest
4. Click Custom Repository and add http://your_local_repo/cdp-pvc-ds/latest as a custom repository.
5. Click the Select Repository drop-down and select http://your_local_repo/cdp-pvc-ds/latest
Click Continue.
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 Continue.
On the Specify Hosts page, hosts that have already been added to Cloudera Manager are listed on the Currently Managed Hosts tab. You can select one or more of these hosts to add to the ECS cluster.

You can also click the New Hosts tab to specify one or more hosts that have not been added to Cloudera Manager. Enter a Fully Qualified Domain Name in the Hostname box, then click Search.

note
Click the pattern link under the Hostname box to display more information about allowed FQDN patterns.

After you have finished specifying the ECS hosts, click Continue.
On the Select JDK page, select any one from the below options:
1. Manually manage JDK
2. Install a Cloudera-provided version of OpenJDK
3. Install a system-provided version of OpenJDK
On the Enter Login Credentials page, All hosts accept the same password is selected by default. Enter the user name in the SSH Username box, and type in and confirm the password. You can also select the All hosts accept the same private key option and provide the Private Key and passphrase.
The Install Agents page appears.
On the Assign Roles page, you can customize the roles assignment for your new Private Cloud Containerized cluster.

important
Cloudera does not recommend altering assignments unless you have specific requirements such as having selected a specific host for a specific role.

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.

Click Continue.

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 Repository

This 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

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.

note
If you are installing ECS on a single node, you should select the Use a Custom Docker Repository option. Single node ECS installation is supported, but is only intended to enable CDSW to CML migration.
You must enter the following options:
- 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.
  important
  Do not use the $ character for this password.
- Docker Certificate – Click the Choose File button to upload a TLS certificate to secure communications with the Docker Repository.
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:
```
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.

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.

note

The "Ingress Controller TLS/SSL Server Certificate File (PEM Format)" must only contain -----BEGIN CERTIFICATE----- through -----END CERTIFICATE----- (inclusive) for the server and CA certs. It cannot include any preamble text and, and must not include a private key.

The "Ingress Controller TLS/SSL Server Private Key File (PEM Format)" must only contain the unencrypted key, and only the header through the footer, with no preamble text.

Both of these files must be readable by the "cloudera-scm" account.

For information on the required entries that must be present in DNS and TLS certificates when not using wildcards, refer to 'No Wildcard DNS/TLS Setup'

Click Continue.
On the Configure Databases page, click Continue.
On the Install Parcels page, the selected parcel is downloaded to the Cloudera Manager server host, distributed, unpacked, and activated on the ECS cluster hosts. Click Continue.
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.

Click Continue.
The installation progress is displayed on the Install Data Services page.
When the installation is complete, you will see the Summary image. You can now launch CDP Private Cloud.
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.
