Embedded Container Service (ECS) Deployment

This article explains the necessary steps to install the ECS platform upon successful deployment and configuration of CDP PvC Base cluster. Please ensure that all the prerequisites have already been prepared accordingly.

• ECS Platform Installation

Sanity Check

1. Ensure that JDK has already been installed in each ECS node.

    # rpm -qa | grep jdk
    copy-jdk-configs-3.3-10.el7_5.noarch
    java-11-openjdk-11.0.14.1.1-1.el7_9.x86_64
    java-11-openjdk-headless-11.0.14.1.1-1.el7_9.x86_64
    java-11-openjdk-devel-11.0.14.1.1-1.el7_9.x86_64
   

2. The external DNS server must contain the forward and reverse zones of the company domain name. The external DNS server must be able to resolve the hostname of all ECS nodes and the 3rd party components (includes Kerberos, LDAP server, external database, NFS server) and perform reverse DNS lookup. Repeat this step for every ECS node.

    # nslookup idm
    Server:	10.15.4.150
    Address:	10.15.4.150#53
   
    Name:	idm.cdpkvm.cldr
    Address: 10.15.4.150
   
    # nslookup 10.15.4.150
    150.4.15.10.in-addr.arpa	name = idm.cdpkvm.cldr.
   

3. NTP client of each ECS node is synchronizing time with the external NTP server.

4. Ensure that ECS master node is able to resolve console-cdp.apps.ecs1.cdpkvm.cldr to the IP address of ECS master/server node or the Load Balancer (if being used).

    # nslookup console-cdp.apps.ecs1.cdpkvm.cldr
    Server: 10.15.4.150
    Address:	10.15.4.150#53
   
    Name:	console-cdp.apps.ecs1.cdpkvm.cldr
    Address: 10.15.4.166
   

5. If Nvidia GPU card is involved, please install the Nvidia driver and its associated software as described in this topic.

ECS Platform Installation

1. Navigate to Clusters > Add Cluster. Select Data Services and click Continue.

   

2. Select Internet and click Continue.

   

3. Enter the FQDN of each ECS node and click Search. Upon successful scan, the hostname alongside each host’s IP address will appear. Check the details before clicking Continue.

   

4. Ensure that JDK has already been installed in each ECS node. Select Manually manage JDK and click Continue.

   

5. Enter the login credentials. Click Continue.

   

6. CM is installing the agent in each ECS node in parallel and will subsequently install the parcels.

   

7. Select all ECS nodes in the Docker Server field. Select the ECS master node in the Ecs Server field and select the ECS worker nodes in the Ecs Agent field. Click View By Host to confirm your choices.

   

   Click Close and Continue.

   

8. Click Continue.

   

9. Review and amend the parameters accordingly. Directory path for Longhorn storage and local SSD/NVMe (for CDW cache) in each node must be configured here in accordance to the mounted disk folder name. Dedicated storage disk that is expected to be formatted and mounted prior to this installation as explained in the prerequisites subtopic. The Application Domain field determines the subdomain of the wildcard DNS. In this case, the wildcard DNS to be set at the external DNS server is *.apps.ecs1.cdpkvm.cldr.

   

10. Fill in the database parameters based on the created databases in PostgreSQL. Click Test Connection. After getting successful result, click Continue.

    

    

11. CM is installing the parcels in each ECS node in parallel.

    

12. Select Inspect hosts. Check the results if needed. Otherwise, click Continue.

    

13. CM will proceed to install the ECS platform. This process will take some time to complete. After successful installation, click Continue.

    

14. Navigate to Clusters > ECS 1. Status of all components are supposed to be in green mode as depicted below.

    

15. Click ECS. You may explore other ECS related dashboards such as Storage UI and ECS Web UI.
