Is it Possible to run Container Image of Oracle Database 18c XE on K8s cluster created using Ubuntu 20.04 LTS

Aniket SahuDec 29 2023

I am new to Oracle Database.
I have created a K8s Cluster with 1 Master Node and 2 Worker Node.

All three Nodes are Virtual Machine running with Ubuntu OS.
OS Details
**********
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.3 LTS
Release: 22.04
Codename: jammy
Kernel Version: #97-ubuntu SMP
Kubernetes Version: 1.27.4
Containerd://1.6.21

Can I deploy Oracle Database 18c XE in the Kubernetes Cluster? If yes can I configure data replication for Single Instance Docker image Oracle Database 18c XE.
I am asking because as per Github (https://github.com/oracle/docker-images/blob/main/OracleDatabase/README.md) it is single instance..

How doc gen treats nulls values?

You have to be more specific. Are your referring to the pre-built Document Generator function?

If so:

When my query return null in some columns

What is the JSON that is generated?

You should always include the element in the JSON, with an empty value. Don't leave it out.

Since September 2024, when a tag has no corresponding value in the JSON data or the value is null, the tag is replaced by an empty string.

See the September Release Notes
