Jhipster-Logstash無法正確啟動

Question

我使用命令docker-compose up來部署所有的docker機器。 這很好，但是當我停止所有docker實例並手動重啟時，我遇到了logstash的問題：

{:timestamp=>"2016-07-12T08:06:11.710000+0000", :message=>"Pipeline main started"}
{:timestamp=>"2016-07-12T08:06:11.815000+0000", :message=>"Pipeline main has been shutdown"}
{:timestamp=>"2016-07-12T08:06:14.723000+0000", :message=>"stopping pipeline", :id=>"main"}
{:timestamp=>"2016-07-12T08:07:47.582000+0000", :message=>"Pipeline main started"}
{:timestamp=>"2016-07-12T08:07:47.692000+0000", :message=>"Pipeline main has been shutdown"}
{:timestamp=>"2016-07-12T08:07:50.585000+0000", :message=>"stopping pipeline", :id=>"main"}

所以當我在kubernetes中部署並且不能使用docker-compose時，我有同樣的問題。

我剛遇到類似的問題。

沒有-ti

    # docker run --rm logstash:2.3.4 logstash --debug --verbose -e 'input { stdin { } } output { stdout { } }'
    {:timestamp=>"2016-08-03T03:24:48.618000+0000", :message=>"starting agent", :level=>:info}
    {:timestamp=>"2016-08-03T03:24:48.629000+0000", :message=>"starting pipeline", :id=>"main", :level=>:info}
    {:timestamp=>"2016-08-03T03:24:48.816000+0000", :message=>"Starting pipeline", :id=>"main", :pipeline_workers=>1, :batch_size=>125, :batch_delay=>5, :max_inflight=>125, :level=>:info}
    {:timestamp=>"2016-08-03T03:24:48.827000+0000", :message=>"Pipeline main started"}
    {:timestamp=>"2016-08-03T03:24:48.848000+0000", :message=>"Input plugins stopped! Will shutdown filter/output workers.", :level=>:info}
    {:timestamp=>"2016-08-03T03:24:48.953000+0000", :message=>"Pipeline main has been shutdown"}
    {:timestamp=>"2016-08-03T03:24:51.834000+0000", :message=>"stopping pipeline", :id=>"main"}
    {:timestamp=>"2016-08-03T03:24:51.843000+0000", :message=>"Closing inputs", :level=>:info}
    {:timestamp=>"2016-08-03T03:24:51.844000+0000", :message=>"Closed inputs", :level=>:info}

隨着-ti

    # docker run -ti --rm logstash:2.3.4 logstash --debug --verbose -e 'input { stdin { } } output { stdout { } }'
    starting agent {:level=>:info}
    starting pipeline {:id=>"main", :level=>:info}
    Settings: Default pipeline workers: 1
    Starting pipeline {:id=>"main", :pipeline_workers=>1, :batch_size=>125, :batch_delay=>5, :max_inflight=>125, :level=>:info}
    Pipeline main started
    ^CSIGINT received. Shutting down the agent. {:level=>:warn}
    stopping pipeline {:id=>"main"}
    Closing inputs {:level=>:info}
    Closed inputs {:level=>:info}
    ^CSIGINT received. Terminating immediately.. {:level=>:fatal}

看起來除了stdin你沒有任何已配置的輸入。

因此，如果你使用composer啟動它，你必須設置tty: true

# cat docker-compose.yml 
version: '2'
services:
    logstash:
        image: logstash:2.3.4
        command: logstash --verbose --debug
        tty: true

結果將是

# docker logs -f sync_logstash_1
starting agent {:level=>:info}
starting pipeline {:id=>"main", :level=>:info}
Settings: Default pipeline workers: 1
Starting pipeline {:id=>"main", :pipeline_workers=>1, :batch_size=>125, :batch_delay=>5, :max_inflight=>125, :level=>:info}
Pipeline main started
