## Prerequisites

Make sure you have the ksonnet v0.8.0:
Make sure you have a recent version of [Tanka](https://github.com/grafana/tanka). Follow their [install instructions](https://tanka.dev/#getting-started) to do so. Make sure to install [jsonnet-bundler](https://github.com/jsonnet-bundler/jsonnet-bundler) as well.

```
$ brew install https://raw.githubusercontent.com/ksonnet/homebrew-tap/82ef24cb7b454d1857db40e38671426c18cd8820/ks.rb
$ brew pin ks
$ ks version
ksonnet version: v0.8.0
jsonnet version: v0.9.5
client-go version: v1.6.8-beta.0+$Format:%h$
```bash
# Verify it works
$ tk --version
tk version v0.5.0
```

In your config repo, if you don't have a ksonnet application, make a new one (will copy credentials from current context):
In your config repo, if you don't yet have the directory structure of Tanka set up:

```
$ ks init <application name>
$ cd <application name>
$ ks env add loki --namespace=loki
```bash
# create a directory (any name works)
$ mkdir config && cd config/
$ tk init
$ tk env add loki --namespace=loki
```

## Deploying Promtail to your cluster.

Grab the promtail module using jb:

$ go get -u github.com/jsonnet-bundler/jsonnet-bundler/cmd/jb
$ jb init
$ jb install github.com/grafana/loki/production/ksonnet/promtail
```
