Kustomize plugins

The following examples illustrate how Kustomize plugins work.

The following examples illustrate how Kustomize plugins work--that is, illustrate Kustomize Kubernetes Resource Model (KRM) Functions Specification with the following examples:

	# e - list files sorted by time, also filter and edit if only 1 match
	# usage: e pattern1 pattern2 ...
	pattern=$(echo "$@" \| awk '
	BEGIN { printf "//" }
	{ for (i = 1; i <= NF; i++)
	printf(" && /%s/", $i) }')
	matches=$(ls -t \| tac \| awk "$pattern")
	echo "$matches"
	if test $(echo "$matches" \| wc -l) -eq 1
	then

	Build mbigras/blueapp:v1 Docker image.
