Travis Go Report Card Join the chat at https://gitter.im/infinitbyte/gopa FOSSA Status

Goal

  • Light weight, low footprint, memory requirement should < 100MB
  • Easy to deploy, no runtime or dependency required
  • Easy to use, no programming or scripts ability needed, out of box features

Screenshoot

What a Spider! GOPA Spider!


How to use

Requirements

  • Elasticsearch v5.3+

Setup

First of all, get it, two opinions: download the pre-built package or compile it yourself.

Download Pre Built Package

Go to Release or Snapshot page, download the right package for your platform.

Note: Darwin is for Mac

Compile The Package Manually

So far, we have:

gopa, the main program, a single binary.
gopa.yml, main configuration for gopa.

Required Config

Note: Elasticsearch version should >= v5.3

  • Enable elastic module in gopa.yml, update the elasticsearch's setting:
- name: elastic
  enabled: true
  kv_enabled: true
  orm_enabled: true
  elasticsearch:
    endpoint: http://localhost:9200
    index_prefix: gopa-
    username: elastic
    password: changeme

Start

Besides Elasticsearch, Gopa doesn't require any other dependencies, just simply run ./gopa to start the program.

Gopa can be run as daemon(Note: Only available on Linux and Mac):

Example
➜  gopa git:(master) ✗ ./bin/gopa --daemon

 /  _____/ \_____  \\______   \/  _  \
/   \  ___  /   |   \|     ___/  /_\  \

 \______  /\_______  /____|  \____|__  /
        \/         \/                \/
[gopa] 0.10.0_SNAPSHOT
///last commit: 99616a2, Fri Oct 20 14:04:54 2017 +0200, medcl, update version to 0.10.0 ///

[10-21 16:01:09] [INF] [instance.go:23] workspace: data/gopa/nodes/0 [gopa] started.

Also run ./gopa -h to get the full list of command line options.

Example
➜  gopa git:(master) ✗ ./bin/gopa -h
  ________ ________ __________  _____
 /  _____/ \_____  \\______   \/  _  \
/   \  ___  /   |   \|     ___/  /_\  \
\    \_\  \/    |    \    |  /    |    \
 \______  /\_______  /____|  \____|__  /
        \/         \/                \/
[gopa] 0.10.0_SNAPSHOT
///last commit: 99616a2, Fri Oct 20 14:04:54 2017 +0200, medcl, update version to 0.10.0 ///

Usage of ./bin/gopa: -config string the location of config file (default "gopa.yml") -cpuprofile string write cpu profile to this file -daemon run in background as daemon -debug run in debug mode, gopa will quit with panic error -log string the log level,options:trace,debug,info,warn,error (default "info") -log_path string the log path (default "log") -memprofile string write memory profile to this file -pidfile string pidfile path (only for daemon) -pprof string enable and setup pprof/expvar service, eg: localhost:6060 , the endpoint will be: http://localhost:6060/debug/pprof/ and http://localhost:6060/debug/vars

Stop

It's safety to press ctrl+c stop the current running Gopa, Gopa will handle the rest,saving the checkpoint, you may restore the job later,the world is still in your hand.

If you are running Gopa as daemon, you may stop it like this:

 kill -QUIT `pgrep gopa`
