I have tried to run a simple `make deploy`. First problem was my GOPATH was blank (even though the golang was installed). After that was fixed, I needed to actually run `make vendor` before I could even consider running `make deploy`. I also needed to add my GOPATH/bin directory to path as it did not find gojsontoyaml otherwise
`export PATH=$PATH:$GOPATH/bin`
Error I was solving:
```
$ make deploy
Installing jsonnet
rm -rf manifests
./scripts/build.sh main.jsonnet /home/xzy/cluster-monitoring/bin/jsonnet
using jsonnet from arg
+ set -o pipefail
+ rm -rf manifests
+ mkdir manifests
+ /home/xyz/cluster-monitoring/bin/jsonnet -J vendor -m manifests main.jsonnet
+ xargs '-I{}' sh -c 'cat {} | gojsontoyaml > {}.yaml; rm -f {}' -- '{}'
