gosuv

Should not use in production now (current is in beta)

Process management writtern by golang, inspired by python-supervisor

So why write another supervisor?

I have been using python-supervisor for many years and there are something uncomfortable feelings.

1. Log can't contains ANSI color chars
2. The configuration file can add on the web, often forgot some settings.
3. supervisorctl reload will cause supervisord restarted
4. Hard to set status change to fatal notifications.
5. No process performance monitor page.
6. Program starts with no common environ, eg, missing HOME and USER variable
7. Kill process default is not group kill which make sub process still running.
8. More... will added when I think of it.

Or if you have go enviroment, you can also build from source.

go get -d github.com/codeskyblue/gosuv
cd $GOPATH/src/github.com/codeskyblue/gosuv
go build

If you want to build a standalone binary, run the following command.

go get github.com/elazarl/go-bindata-assetfs/...
go-bindata-assetfs -tags bindata res/...
go build -tags bindata

Quick start

After you installed gosuv, the first thing is to start server.

gosuv start-server

Show server status

$ gosuv status
Server is running

Open web http://localhost:11313 to see the manager page. And follow the gif to add a program to gosuv.

Configuration

Default config file stored in directory $HOME/.gosuv/, Set env-var GOSUV_HOME_DIR can change config file store directory.

• file programs.yml contains all program settings.
• file config.yml contains server config

File config.yml can be generated by gosuv conftest

Example config.yaml

server:
  httpauth:
    enabled: false
    username: uu
    password: pp
  addr: :11313
client:
  server_url: http://localhost:11313

Logs can be found in $HOME/.gosuv/log/

Edit config file(default located in $HOME/.gosuv/programs.yml) and run gosuv reload will take effect immediately.

Design

HTTP is follow the RESTFul guide.

Get or Update program

<GET|PUT> /api/programs/:name

Add new program

POST /api/programs

Del program

DELETE /api/programs/:name

State

Only 4 states. ref

Notification

Configuration example

- demo-program:
  command: ...
  notifications:
    pushover:
      api_key: [token]
      users:
      - [user1]
      - [user2]

Now only support pushover, and only status change to fatal will get notified.

Integrate with github (todo)

This is feature that will helps update your deployment environment once your updated in the github.

This part is set in the programs.yml, take look the example

- demo-program:
  command: python app.py
  directory: /opt/demo
  webhook:
    github:
      secret: 123456
      command: git pull origin master
