Docker容器中运行flume及启动不输出运行日志问题

flume配置文件如下：

# Name the components on this agent
app1.sources = r1
app1.sinks = k1
app1.channels = c1
# Describe/configure the source
app1.sources.r1.type = avro
app1.sources.r1.bind = 0.0.0.0
app1.sources.r1.port = 44444
# Describe the sink
#a1.sinks.k1.type = logger
app1.sinks.k1.type = file_roll
app1.sinks.k1.sink.directory = /var/log/my/app1
app1.sinks.k1.sink.rollInterval=86400
app1.sinks.k1.sink.batchSize=100
app1.sinks.k1.sink.serializer=text
app1.sinks.k1.sink.serializer.appendNewline = false
# Use a channel which buffers events in memory
app1.channels.c1.type = memory
app1.channels.c1.capacity = 1000
app1.channels.c1.transactionCapacity = 100
app1.channels.c1.byteCapacity = 100000000
app1.channels.c1.byteCapacityBufferPercentage = 10
# Bind the source and sink to the channel
app1.sources.r1.channels = c1
app1.sinks.k1.channel = c1
# Name the components on this agent
app2.sources = r2
app2.sinks = k2
app2.channels = c2
# Describe/configure the source
app2.sources.r2.type = avro
app2.sources.r2.bind = 0.0.0.0
app2.sources.r2.port = 44445
# Describe the sink
#a1.sinks.k1.type = logger
app2.sinks.k2.type = file_roll
app2.sinks.k2.sink.directory = /var/log/my/app2
app2.sinks.k2.sink.rollInterval=86400
app2.sinks.k2.sink.batchSize=100
app2.sinks.k2.sink.serializer=text
app2.sinks.k2.sink.serializer.appendNewline = false
# Use a channel which buffers events in memory
app2.channels.c2.type = memory
app2.channels.c2.capacity = 1000
app2.channels.c2.transactionCapacity = 100
app2.channels.c2.byteCapacity = 100000000
app2.channels.c2.byteCapacityBufferPercentage = 10
# Bind the source and sink to the channel
app2.sources.r2.channels = c2
app2.sinks.k2.channel = c2 

dockerfile如下：

下面看下flume 启动不输出运行日志

问题

以前碰到的一个问题，算是一个小问题，flume 用命令

./flume-ng agent -c /opt/apps/flume/conf -f /opt/apps/flume/conf/syslog_tcp.conf -n a1 -Dflume.root.logger=INFO,console

启动的时候，flume使用的log4j不起效，不会输出日志到日志文件。

解决

在启动时去掉

-Dflume.root.logger=INFO,console

这个命令就好了。flume的log4j就正常工作了。也算是一个坑。

加上这个命令会将运行的日志在控制台输出。
