New page

This is a great plugin for helm.

helm plugin install https://github.com/databus23/helm-diff

helm diff upgrade -n mynamespace myapp foo/myapp -f custom-values.yaml

You could use it like so

```
#!/bin/bash
lines=$(helm diff upgrade -n mynamespace myapp foo/myapp -f custom-values.yaml)
if [[ $(echo $lines | wc -l) > 0 ]]; then
echo "$lines" | grep "^+\|^-"
echo "Helm changes detected."
echo "Running upgrade in 5."; sleep 5 helm upgrade --install -n mynamespace myapp foo/myapp -f custom-values.yaml
fi
```
