# `lacework-cli`

The Lacework Command Line Interface is a tool that helps you manage your
Lacework cloud security platform. You can use it to manage compliance
reports, external integrations, vulnerability scans, and other operations.

## Install

### Bash:
```
$ curl https://raw.githubusercontent.com/lacework/go-sdk/master/cli/install.sh | sudo bash
```

### Powershell:
```
C:\> Set-ExecutionPolicy Bypass -Scope Process -Force
C:\> iex ((New-Object System.Net.WebClient).DownloadString('https://raw.githubusercontent.com/lacework/go-sdk/master/cli/install.ps1'))
```

## Configuration File

The `lacework-cli` looks for a file named `.lacework.toml` inside your home
directory (`$HOME/.lacework.toml`) to access the following parameters:
* `account`: Account subdomain of URL (i.e. `<ACCOUNT>.lacework.net`)
* `api_key`: API Access Key ID
* `api_secret`: API Access Secret Key


An example of a Lacework configuration file:
```toml
account = "example"
api_key = "EXAMPLE_1234567890ABC"
api_secret = "_super_secret_key"
```

You can provide a different configuration file with the option `--config`.

## Basic Usage
Once you have created your configuration file `$HOME/.lacework.toml`,
you are ready to use the Lacework cli, a few basic commands are:

1) List all integration in your account:
```bash
$ lacework-cli integration list
```
1) Use the `api` command to access Lacework's ResfulAPI, for example,
to get details about and specific event:
```bash
$ lacework-cli api get '/external/events/GetEventDetails?EVENT_ID=16700'
```
