Container Operating System upgrade to RHEL UBI (Red Hat Universal Base Image)

From version 12.1.1, the base operating system used for all containers is Red Hat Universal Base Image version 8. Customers get support, bugfixes, and enhancements.

Supporting the restricted containers – lesser privileges

Provides support for restricted containers. Restricted containers refer to the non-root user or rthe estricted user inside the container.

OpenShift supports anyuid, privilege, or restricted SCC. We have customized Unica to fit with any SCC, so that Unica works with anyuid, privilege, or restricted SCC, which runs without any group, and with any user ID.

Support offline clusters (Internet access restriction)

Supports deployment in environment where customer do not have Internet connectivity eliminating the depdency on Internet to download the package for deployment.

ELK Integration

Supports ELK Stack. ELK refers to Elastic search, Logstash, and Kibana. The features added for Cloud Native Unica are as follows:

• Added ELK for logging, monitoring, and metrics.
• Added Filebeat as a sidecar container that fetches logs from Unica log files and pushes it to ELK stack (in the customer environment).
• Added Metricbeat for metrics, which runs as daemonset in the kube-system namespace, and sends different metrics to ELK stack (in the customer env). This helps to track utilization and resolving issues.

• Cloud Native Unica Integration Guide for Apache Tomcat

• Cloud Native Unica Integration Guide for Oracle WebLogic Server

Interact low dependency on PV

Bundled many dependencies in the image so that fewer dependencies need to be referred from the PV.
