The reason is that there is no need for jammy-minimal, here is the size of
the images (not all, but interested ones)
```
xifos@xifos-dev-bionic:~/git/cloudberry-devops/images/docker/cbdb/test/ubuntu22.04$
docker images
REPOSITORY TAG IMAGE ID CREATED
SIZE
ubuntu 22.04 a24be041d957 2 months ago
77.9MB
ubuntu jammy a24be041d957 2 months ago
77.9MB
ubuntu 22.10 692eb4a905c0 21 months ago
70.3MB
```
Compare it with the build/test container size:
```
xifos@xifos-dev-bionic:~/git/cloudberry-devops/images/docker/cbdb/test/ubuntu22.04$
docker images
REPOSITORY TAG IMAGE ID CREATED
SIZE
cloudberry-db-build-env latest 693ae32596fc 20 minutes ago
1.43GB
cloudberry-db-test-env latest 62f2e7df33d6 About an hour ago
286MB
cbdb-main rockylinux9 7ee3e45c3ee1 4 months ago
1.89GB
rockylinux/rockylinux 9 bb8a97547d22 4 months ago
234MB
```
When compared to the size of a build container, a difference of a few
megabytes is negligible.
Guys here
https://askubuntu.com/questions/1455012/where-can-i-find-ubuntu-minimal-22-04-docker-image
also came to the similar conclusion.
According to the https://canonical.com/blog/minimal-ubuntu-released minimal
image actually is 22.04 LTS image
They sad:
> Tiny container base image
> The 29MB Docker image for Minimal Ubuntu 18.04 LTS serves as a highly
efficient container starting point, and allows developers to deploy multicloud
containerized applications faster. For modern Docker workflows with Kubernetes,
the minimal Ubuntu image provides a balance of compatibility, familiarity,
performance and size. This is the standard Ubuntu 18.04 LTS image on the Docker
Hub.
So I switched from jammy to 22.04 base image (but they have the same image
id, I don't think it matters)
