I have requirement to create yaml file which can be used to create configmap in kubernetes.
I have 3 xml files which are need to be imported in template yaml file.
YAML Template:
apiVersion: v1
data:
config1.xml: |-
<Sheet>
.
.
.
</Sheet>
config2.xml: |-
<Sheet>
.
.
.
</Sheet>
config3.xml: |-
<Sheet>
.
.
</Sheet>
kind: ConfigMap
metadata:
name: {{CMPlaceholder}}
namespace: {{NSPlaceholder}}
xml file:
<Sheet>
<Category name="Category1">
<Item name="item1">Cat1Item1.value</Item>
<Item name="item2">Cat1Item2.value</Item>
</Category>
<Category name="Category2">
<Item name="item1">Cat2Item1.value</Item>
<Item name="item2">Cat2Item2.value</Item>
</Category>
<Category name="Category3">
<Item name="item1">Cat3Item1.value</Item>
<Item name="item2">Cat3Item2.value</Item>
</Category>
<Category name="Groups">
<Item name="Group1" commarea="Y">G1.Value</Item>
<Item name="Group2" commarea="Y">G2.Value</Item>
<Item name="Group3" commarea="Y">G3.Value</Item>
<Group1 name="G1.Value">
<spec name="ISOS">
<specdetails name="name1">spvalue1</specdetails>
<specdetails name="name2">spvalue2</specdetails>
<specdetails name="name3">spvalue3</specdetails>
<specdetails name="name4">spvalue4</specdetails>
</spec>
</Group1>
.
.
<Group2 name="G2.Value"></Group2>
.
.
<Group3 name="G3.Value"></Group3>
.
<Category name="FinalProducts">
<Item name="Product1">Product1FinalValue</Item>
<Item name="Product2">Product2FinalValue</Item>
<Item name="Product3">Product3FinalValue</Item>
<Item name="Product4">Product4FinalValue</Item>
</Category>
</Category>
</Sheet>
Similary I have 2 more xml files. I need some script to prepare the final YAML so that I can use it to create configmap in azure kubernetes service using below command
kubectl apply -f "YAMLFILEPATH"
Expecting script to take below arguments.
.script.sh or .script.ps1 -YamlTemplate "PathOfYAMLFile" -config1.xml "PathOfConfig1.xml" -config2.xml "PathOfConfig2.xml" -config3.xml "PathOfConfig3.xml" -configMapName "group-product-spec" -namespace "organization"
Output of the script should be yaml created in the same directory with the name group-product-spec.yaml

Suppose you have three xml files, and you need to create script which can be used to create configmap in kubernetes.
I am showing via bash so let’s say I create a create-configmap.sh
#!/bin/bash
# Function to display help message
function display_help() {
echo "Usage: $0 -YamlTemplate <PathOfYAMLFile> -config1 <PathOfConfig1.xml> -config2 <PathOfConfig2.xml> -config3 <PathOfConfig3.xml> -configMapName <group-product-spec> -namespace <organization>"
exit 1
}
while [[ $# -gt 0 ]]; do
case "$1" in
-YamlTemplate)
YamlTemplate="$2"
shift 2
;;
-config1)
Config1="$2"
shift 2
;;
-config2)
Config2="$2"
shift 2
;;
-config3)
Config3="$2"
shift 2
;;
-configMapName)
ConfigMapName="$2"
shift 2
;;
-namespace)
Namespace="$2"
shift 2
;;
*)
display_help
;;
esac
done
# Check if all required arguments are provided
if [ -z "$YamlTemplate" ] || [ -z "$Config1" ] || [ -z "$Config2" ] || [ -z "$Config3" ] || [ -z "$ConfigMapName" ] || [ -z "$Namespace" ]; then
display_help
fi
# Read the content of XML files
Config1Content=$(cat "$Config1")
Config2Content=$(cat "$Config2")
Config3Content=$(cat "$Config3")
# Create the final YAML file by replacing placeholders
OutputYaml="${ConfigMapName}.yaml"
cat <<EOF > "$OutputYaml"
apiVersion: v1
data:
config1.xml: |-
$(echo "$Config1Content" | sed 's/^/ /')
config2.xml: |-
$(echo "$Config2Content" | sed 's/^/ /')
config3.xml: |-
$(echo "$Config3Content" | sed 's/^/ /')
kind: ConfigMap
metadata:
name: $ConfigMapName
namespace: $Namespace
EOF
echo "ConfigMap YAML file created at $OutputYaml"
Make the script executable chmod +x create-configmap.sh
Run the script
./create-configmap.sh -YamlTemplate "template.yaml" -config1 "config1.xml" -config2 "config2.xml" -config3 "config3.xml" -configMapName "group-product-spec" -namespace "<whatever_is_your_namespace>"
and finally check using kubectl get configmap group-product-spec
and if you describe it, you can see your xml loaded properly
kubectl describe configmap group-product-spec -n default
