#### 1.环境准备： ####

#### 安装ElasticSearch、Kibana、LogStash。 ####

docker内，下载需要的镜像。然后启动一个镜像。

**创建并运行一个ElasticSearch容器：**

docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9200:9200 -p 9300:9300 --name MyES elasticsearch:6.8.8
    
    
    
    #7.6.2 启动需要增加discovery.type=single-node
    docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -e discovery.type=single-node  -d -p 9200:9200 -p 9300:9300 --name MyES elasticsearch:7.6.2

> **浏览器访问测试：http://127.0.0.1:9200，应输出如下结果：**

{
        
        "name": "WQawbNC",
        "cluster_name": "docker-cluster",
        "cluster_uuid": "f6QviESlT_e5u3kaZFHoWA",
        "version": {
        
            "number": "6.8.8",
            "build_flavor": "default",
            "build_type": "docker",
            "build_hash": "2f4c224",
            "build_date": "2020-03-18T23:22:18.622755Z",
            "build_snapshot": false,
            "lucene_version": "7.7.2",
            "minimum_wire_compatibility_version": "5.6.0",
            "minimum_index_compatibility_version": "5.0.0"
        },
        "tagline": "You Know, for Search"
    }

**创建并运行运行一个Kibana容器：**  
创建之前，先查看ES在docker中的ip地址，因为我们的kibana在启动的时候需要连接到ES。

#先使用命令 docker ps 查看ES容器ID
    docker ps
    	#输出如下:
    	CONTAINER ID   IMAGE                 COMMAND                  CREATED        STATUS        PORTS                                            NAMES
    	a266d1ff5c1b   elasticsearch:6.8.8   "/usr/local/bin/dock…"   19 hours ago   Up 18 hours   0.0.0.0:9200->9200/tcp, 0.0.0.0:9300->9300/tcp   MyES
    #通过容器ID，查看容器IP地址。以上的a266d1ff5c1b就是我们ES的容器ID
    docker inspect --format '{
        { .NetworkSettings.IPAddress }}' a266d1ff5c1b
    	#输出如下:
     	172.17.0.3

**得到了ES容器IP地址之后，创建并运行一个Kibana容器。**

#注意，此处的ELASTICSEARCH_URL需替换成上面ES容器的IP地址，否则Kibana连接不到ES
    docker run -d --name MyKibana -p 5601:5601 -e ELASTICSEARCH_URL=http://172.17.0.3:9200 kibana:6.8.8

> **浏览器访问测试：http://127.0.0.1:5601：**

**创建并运行运行一个LogStash容器：**

docker run -d -p 9600:9600 -p 4560:4560 --name MyLogStash logstash:6.8.8

运行后，进入容器内部。修改logstash.yml配置文件：

docker exec -it 容器ID bash
    cd config
    vi logstash.yml
    # 改成如下配置
    http.host: "0.0.0.0"
    xpack.monitoring.elasticsearch.url: http://es所在的ip:9200
    xpack.monitoring.elasticsearch.username: elastic
    xpack.monitoring.elasticsearch.password: changme

修改pipeline下的logstash.conf文件

input {
      tcp {
    	 #模式选择为server
        mode => "server"
        #ip和端口根据自己情况填写，端口默认4560,对应下文logback.xml里appender中的destination
        host => "logstash所在的ip地址"
        port => 4560
        #格式json
        codec => json_lines
        
     }
    }
    
    output {
    elasticsearch {
    	action => "index"
        #这里是es的地址，多个es要写成数组的形式
        hosts  => "172.17.0.3:9200"
        #用于kibana过滤，可以填项目名称
        index  => "springboot-logstash"
      }	
      stdout {
        codec => rubydebug
      }
    }

最后重启我们的logstash

docker restart MyLogStash

#### 2. 使ELK与SpringBoot集成 ####
