+Most of my personal projects are deployed via kubernetes. I write a lot of
+*deployment.yaml* files. In order to keep them clean and checked in to version control
+I keep sensitive env variables in a config maps. Problem is adding values env values to 
+*deployment.yaml* files is pretty painful. This makes it a little less. 
+
+placed in *yaml.json* 😀 what a file name!
+
+```json
+{
+	"env var from configmap": {
+		"prefix": "env",
+		"body": [
+			"- name: $1",
+			"  valueFrom:",
+			"    configMapKeyRef:",
+			"      key: $1",
+			"      name: configmapname"
+		],
+		"description": "env varable from config map, remember to replace configmapname with your configmap name"
+	}
+}
+```
