Unhandled rejection Error: HTTP code is 404

[fullyfaltu]

I'm trying to notify my slack channel for every docker event. But couldn't succeed yet. Got following error:

Unhandled rejection Error: HTTP code is 404 which indicates error: no such container - [object Object]

How can I solve this issue? Thanks in advance.

Hi,

This is because dockerode stream other event types than container (like network or volume)

Examples :

{ Type: 'volume',
  Action: 'mount',
  Actor:
   { ID: 'mysql_data',
     Attributes:
      { container: 'd2169583beae6b4916626422a5907f05c7e74d718191b96c1f768181bf47f511',
        destination: '/var/lib/mysql',
        driver: 'local',
        propagation: '',
        'read/write': 'true' } },
  time: 1493816904,
  timeNano: '1493816904332490264' }

or

{ Type: 'network',
  Action: 'connect',
  Actor:
   { ID: 'fbf740ad0300aa6a60c8a381c848c80d6721f343c9d2a6738e2a1f24d73725d4',
     Attributes:
      { container: 'd2169583beae6b4916626422a5907f05c7e74d718191b96c1f768181bf47f511',
        name: 'mysql_network',
        type: 'bridge' } },
  time: 1493816904,
  timeNano: '1493816904304038536' }

You have to filter those events at line 15

if ((!event.Type || event.Type == 'container') && this._imageRegExp.test(event.from)) {
