Description Christian Horn 2023-01-05 09:04:12 UTC 
Document URL: 
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html-single/building_running_and_managing_containers/index#using-the-ubi-init-images_assembly_adding-software-to-a-ubi-container

Section Number and Name: 
6.1. Using the UBI init images

Describe the issue: 
The section has
"FROM registry.access.redhat.com/ubi9/ubi-init RUN dnf -y install httpd;[..]"
which is not a proper syntax.  Putting that in a Containerfile and running 'podman build .' leads to error:

Error: FROM requires either one argument, or three: FROM <source> [as <name>]

Suggestions for improvement: 
Separate lines, i.e.
```
FROM registry.access.redhat.com/ubi9/ubi-init 
RUN dnf -y install httpd; dnf clean all; systemctl enable httpd; 
RUN echo "Successful Web Server Test" 
[...]
```
