为什么要创建日志文件>内部容器？配置日志驱动程序将更加灵活。

以下示例被设计，但演示如何收集来自所有容器的日志记录事件。我建议您进一步阅读 fluentd 中提供的选项。

示例

首先运行流畅的内容器收集日志事件

  mkdir log 
 docker run -d --name fluentd -p 24224 ：24224 -v $ PWD：/ fluentd / etc -v $ PWD / log：/ fluentd / log -e FLUENTD_CONF = log.conf fluent / fluentd 
 

现在运行一个容器来创建要记录的事件：

  docker run  - -log-driver = fluentd ubuntu echo hello world 
 

示例配置将日志事件发送到输出日志文件

 ├──log 
│└──events.20160901.b53b670f22298bbcb 
└──日志。 conf 
 

log.conf

 <信源&GT; 
 @type转发
端口24224 
< / source> 

< match **> 
 @type file 
 path / fluentd / log / events 
 append true 
< / match>

你是否结婚到Oracle JDK？以下Docker文件将会相当简单：

  FROM openjdk：8 
添加目标/ demo-1.0.jar / opt /demo/demo-1.0.jar 
 CMD [java， -  jar，/ opt / demo / demo-1.0.jar] 
 

I write the docker file for run the jar file and it does not create the log file for see the console below is my docker file

From ubuntu 
RUN apt-get update && \
    apt-get upgrade -y && \
    apt-get install -y  software-properties-common && \
    add-apt-repository ppa:webupd8team/java -y && \
    apt-get update && \
    echo oracle-java8-installer shared/accepted-oracle-license-v1-1 select true | /usr/bin/debconf-set-selections && \
    apt-get install -y oracle-java8-installer && \
    apt-get clean
VOLUME /temp
RUN apt-get install -y vim
ADD real_estate_false.jar /real_estate_false.jar
COPY real_estate_false_lib /real_estate_false_lib
COPY resources /resources
COPY testxml /testxml
CMD ["java","-jar","/real_estate_false.jar",">","var/log/jar.log"]

Why are you creating a logging file inside the container? Configuring a logging driver would be more flexible.

The following example is contrived, but demonstrates how logging events from all your containers could be collected. I suggest reading further into the options available from fluentd

Example

First run fluentd within a container to collect log events

mkdir log
docker run -d --name fluentd -p 24224:24224 -v $PWD:/fluentd/etc -v $PWD/log:/fluentd/log -e FLUENTD_CONF=log.conf fluent/fluentd

Now run a container that creates an event to be logged:

docker run --log-driver=fluentd ubuntu echo hello world

The sample configuration sends log events to an output log file

├── log
│   └── events.20160901.b53b670f22298bbcb
└── log.conf

log.conf

<source>
  @type  forward
  port  24224
</source>

<match **>
   @type file
   path         /fluentd/log/events
   append       true
</match>
