Printed Page 188
2nd paragraph

In chapter 20, second paragraph of page 188 says

"Prefix all suitable ConfigMap keys with CONFIG_. With the ConfigMap defined in Example 20-1, this leads to three exposed environment variables:
CONFIG_PATTERN_NAME, CONFIG_EXTRA_OPTIONS, and CONFIG_SEED."

CONFIG_PATTERN_NAME is a typo. It should be just CONFIG_PATTERN as Example 20-1 has the following entries

apiVersion: v1
kind: ConfigMap
metadata:
name: random-generator-config
data:
PATTERN: Configuration Resource
application.properties: |
# Random Generator config
log.file=/tmp/generator.log
version=1.0
server.port=7070
EXTRA_OPTIONS: "high-secure,native"
SEED: "432576345"

Example 30-1, Example 30-2

Looking at the script in the example 30-2, I think args in the image-update container should be swapped.

item "pipeline builds"

The pipeline "build strategy" is still based on Jenkins, but it is deprecated in favor of a wholy new addon called "OpenShift Pipelines" that is based on Tekton. However, the tekton CI is not connected to the build strategy but is deployed with separated CRDs (TaskRuns etc.).

Replace Tekton here with Jenkins but also mention that this is deprecated in favor of OpenShift pipelines.

All Kudos to Hayato Matsuura for spotting this
