+# ConfigMaps
+
+## configmap-env-vars.j2
+You can use this to create a configmap with key value pairs. This jinja template will require a dict of the following name and format:
+```yaml
+configmap_env_vars:
+  key1: config1
+  key2: config2
+  key3: config3
+```
+Let's generate a configmap from the above:
+`ansible -i <inventory> all -m template -a "src=configmap-env-vars.j2 dest=/tmp/configmap.yml" -e name=configmap-env-vars -e @/path/to/my/configmap_env_vars`
+The generated configmap now looks like
+```yaml
+---
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: configmap-env-vars
+data:
+  key3: config3
+  key2: config2
+  key1: config1
+```
+
+## configmap-files.j2
+You can use this to create a configmap with multiple keys/files. This jinja template will require a dict of the following name and format:
+```yaml
+configmap_files:
+  file1.yml: |-
+    # This is a comment in 'file1.yml'
+    property1: blue
+  file2.yml: |-
+    property2: yellow
+```
+Let's generate a configmap from the above:
+`ansible -i <inventory> all -m template -a "src=configmap-files.j2 dest=/tmp/configmap.yml" -e name=configmap-files -e @/path/to/my/configmap_files`
+The generated configmap now looks like
+```yaml
+---
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: configmap-files
+data:
+  file1.yml: |
+    # This is a comment in 'file1.yml'
+    property1: blue
+  file2.yml: |
+    property2: yellow
+```
