Stacker is [Salt PillarStack](https://docs.saltstack.com/en/master/ref/pillar/all/salt.pillar.stack.html) in [Crystal](https://crystal-lang.org/).

It is implemented using [crinja](https://github.com/straight-shoota/crinja) which is Jinja2 in Crystal :)

[Documentation](https://jbox-web.github.io/stacker/index.html)

## Installation

### Manual installation

Grab the latest binary from the [releases](https://github.com/jbox-web/stacker/releases) page and run it with the [sample configuration project](https://github.com/jbox-web/stacker/tree/master/example).

If you use [asdf](https://github.com/asdf-vm/asdf) you can also install Stacker with [asdf-stacker](https://github.com/jbox-web/asdf-stacker).

### Docker

```sh
docker pull nicoladmin/stacker:latest
```

**Note :** The Docker mode comes with a [wrapper script](https://github.com/jbox-web/stacker/blob/master/stacker.sh) to ease interactions with the container

```sh
curl -sSL -o stacker.sh https://raw.githubusercontent.com/jbox-web/stacker/master/stacker.sh
chmod +x stacker.sh
```

Usage : `stacker.sh {start|stop|restart|status|kill|clean|fetch|info|logs}`


## The 10 seconds test in Web mode

First we need to start Stacker with sample data :

### Manual installation

```sh
stacker server --config example/stacker.yml
```

### Docker

```sh
./stacker.sh start
```

Then fetch pillars with Curl :

```sh
curl --no-progress-meter -X POST -H "Content-Type: application/json" -d @example/grains/server1.curl.json http://127.0.0.1:3000/server1.example.net | jq
```

You can also navigate to http://127.0.0.1:3000/server1.example.net to see the generated pillars.

## The 10 seconds test in CLI mode

In this mode you don't need the webserver to be running :

### Manual installation

```sh
stacker fetch server1.example.net --config example/stacker.yml --grains example/grains/server1.json --pillar example/ext_pillar/server1.json | jq
```

### Docker

```sh
./stacker.sh fetch server1.example.net --grains grains/server1.json --pillar ext_pillar/server1.json | jq
```

## Usage

```sh
Usage:
  stacker [flags...] [arg...]

Stacker is Salt PillarStack in Crystal

Flags:
  --help     # Displays help for the current command.
  --version  # Displays the version of the current application.

Subcommands:
  fetch      # Fetch host pillars
  info       # Show Stacker information
  server     # Run Stacker webserver
```

## Configuration

By default Stacker looks for it's configuration file in the current directory (`stacker.yml`).

You can pass an alternative file by using `--config` flag.

The configuration file is a YAML file looking like this :

```yml
---
doc_root: example/doc_root
entrypoint: server-pillars
log_file: ./log/stacker.log

stacks:
  default:
    - example/doc_root/server-pillars/stack1.cfg
  dev:
    - example/doc_root/server-pillars/stack1.cfg
    - example/doc_root/pillars/stack1.cfg
  prod:
    - example/doc_root/server-pillars/stack1.cfg
    - example/doc_root/pillars/stack1.cfg
    - example/doc_root/server-pillars/stack2.cfg

server_host: 127.0.0.1
server_port: 3000
server_environment: development
```

**Note :** You can use relative or absolute file path.

Config               | Description
---------------------|------------
`doc_root`           | the webserver document root (must be specified). Since pillar are also crinja templates, it means where are the template files?
`entrypoint`         | the webserver entrypoint (must be specified). The directory in the `doc_root` where we shoud look for `<minion_d>.yml` file
`log_file`           | the path to the log file
`stacks`             | a hash of namespaced [stack configuration files](https://docs.saltstack.com/en/master/ref/pillar/all/salt.pillar.stack.html#list-of-config-files) (must be specified)
`server_host`        | ip address to bind to (default `127.0.0.1`)
`server_port`        | port to bind to (default `3000`)
`server_environment` | `development` or `production` (default `production`)

## Salt integration

To integrate Stacker with Salt you first need to add the [stacker pillar module](/salt/stacker.py) in Salt :

1. Declare extension modules directory in Salt (`/etc/salt/master.conf` or `/etc/salt/master.d/f_defaults.conf`)

```yml
extension_modules: /data/salt/modules
```

2. Create `/data/salt/modules/pillar` directory and puts [stacker module](https://github.com/jbox-web/stacker/blob/master/salt/stacker.py) in it

```sh
mkdir -p /data/salt/modules/pillar
wget -O /data/salt/modules/pillar/stacker.py https://raw.githubusercontent.com/jbox-web/stacker/master/salt/stacker.py
```

3. Declare the new ext_pillar module in Salt

```yml
ext_pillar:
  - stacker: http://127.0.0.1:3000
```

You can also pass parameters to Stacker module :

```yml
ext_pillar:
  - stacker:
      host: http://127.0.0.1:3000
      namespace: 'production'
      log_level: 'debug'
```

4. Restart Salt, you're done :)

## Namespaces

Use namespaces by using optional `n=` query parameter :

```sh
curl http://127.0.0.1:3000/server1.example.net?n=dev
curl http://127.0.0.1:3000/server1.example.net?n=prod
```

Or with `--namespace` flag when using Stacker CLI.

The default namespace when query parameter or CLI flag is omited is `default`.

## Output format

Set output format by using optional `f=` query parameter :

```sh
curl http://127.0.0.1:3000/server1.example.net?f=json
curl http://127.0.0.1:3000/server1.example.net?f=yaml
```

Or with `--output-format` flag when using Stacker CLI.

The default output format when query parameter or CLI flag is omited is `json`.

Only `json` and `yaml` are supported.

## Logs

* log level

The log level is dynamic. No need to restart the web server :)

Set log level by using optional `l=` query parameter :

```sh
curl http://127.0.0.1:3000/server1.example.net?l=debug
curl http://127.0.0.1:3000/server1.example.net?l=trace
```

Or with `--log-level` flag when using Stacker CLI.

The default log level when query parameter or CLI flag is omited is `info`.

Log levels other than `debug` or `trace` are meaningless.

`trace` level is very verbose as it dumps data before and after merge operations. In this case you might need some filtering, see below...

<details><summary>debug level will render something like this :</summary>

* filter logs by template path

Set the file path to debug by using optional `p=` query parameter :

```sh
curl http://127.0.0.1:3000/server1.example.net?l=trace&p=doc_root/pillars/02-roles/server/openssh.yml
```

Or with `--path` flag when using Stacker CLI.

* filter logs by steps

Set the step to debug by using optional `s=` query parameter :

```sh
curl http://127.0.0.1:3000/server1.example.net?l=trace&p=doc_root/pillars/02-roles/server/openssh.yml&s=compile,yaml-load
```

Or with `--step` flag when using Stacker CLI.

Valid options for the `step` param are : `compile` | `yaml-load` | `before-merge` | `after-merge` | `final`

## Scaling

The Stacker's web design leads to great possibilities :

* You can move Stacker and the pillar rendering process out of Salt server :

```yml
ext_pillar:
  - stacker: http://stacker.example.corp:3000
```

* You can run multiple instances of Stacker and call them sequentially :

```yml
ext_pillar:
  - stacker: http://127.0.0.1:3000?n=foo
  - stacker: http://127.0.0.1:4000?n=bar
  - stacker: http://127.0.0.1:5000?n=baz
```

With each instance having it's own stack configuration :)

## Deployment

You can use the [provided systemd unit](https://github.com/jbox-web/stacker/blob/master/extra/stacker.service) to manage the Stacker daemon.

## Merging strategies

Stacker implements [merging strategies](https://docs.saltstack.com/en/master/ref/pillar/all/salt.pillar.stack.html#merging-strategies) like PillarStack so you can use them in Stacker too :)

It works the same way and it's [tested](/spec/stacker/value_spec.cr#L45).

## Template syntax

The [template syntax](https://github.com/straight-shoota/crinja/blob/master/TEMPLATE_SYNTAX.md) is almost the same than Jinja2.

[Like PillarStack](https://docs.saltstack.com/en/master/ref/pillar/all/salt.pillar.stack.html#overall-process) you have access to these variables :

* `stack`
* `pillar`
* `minion_id`
* `grains` (instead of `__grains__`)

Stacker adds a bunch of filters and functions :

Filters :

* json filter (dump json without character escaping) (like the [Salt one](https://docs.saltstack.com/en/latest/topics/jinja/index.html#tojson))
* traverse filter (like the [Salt one](https://docs.saltstack.com/en/latest/topics/jinja/index.html#traverse))
* unique filter (like the [Salt one](https://docs.saltstack.com/en/latest/topics/jinja/index.html#unique))

Functions :

* log function (like the [Salt one](https://docs.saltstack.com/en/latest/topics/jinja/index.html#logs))
* dump function (it dumps objects to YAML in log file)
* array_push function
* merge_dict function

You can see examples of code in the [documentation](https://jbox-web.github.io/stacker/Stacker/Runtime/Filter/Json.html).

## Development

To compile Stacker you will need [Crystal](https://crystal-lang.org) compiler.

You can easily setup your development environment with [asdf](https://github.com/asdf-vm/asdf) :

```sh
git clone https://github.com/jbox-web/stacker
make setup  # Install asdf Crystal plugin and install Crystal compiler
make deps   # Install Stacker dependencies
make build  # Build Stacker in development mode
make relase # Build Stacker in production mode
```

## Extend Stacker

If you need to add filters (or functions) just drop a new class with a few lines of Crystal code in [/src/runtime](https://github.com/jbox-web/stacker/tree/master/src/runtime) and recompile Stacker with `make build` (dev mode) or `make release` (release mode).

Your custom filters (or functions) should be available in Jinja templates. To be sure run `stacker info` and check the Crinja environment info.

Then feel free to submit a PR if you think it will be useful for people.

## Roadmap

* implement [Select Stacker config through grains|pillar|opts matching](https://github.com/saltstack/salt/blob/a670b4ae72ec11f5485c216c54059e14223019b8/salt/pillar/stack.py#L77)
* add documentation about "Stacker - Sample Project"
