log.io实时日志平台docker部署

没有复杂的中间件依赖安装和配置，只要一个简单的docker容器即可搭建一个实时日志查看平台。

下面是我的dockerfie

FROM docker.io/node:20.14.0-alpine
LABEL maintainer="jiafeng"
 
RUN npm config set registry http://registry.npm.taobao.org \
    && npm config set strict-ssl false \
    && npm install -g log.io \
    && npm install -g log.io-file-input \
    && mkdir /root/.log.io \
    && mkdir /home/logs
 
ENV LOG_IO_MODE=server
 
CMD if [ "$LOG_IO_MODE" = "server" ]; then \
        log.io-server; \
    elif [ "$LOG_IO_MODE" = "client" ]; then \
       log.io-file-input; \
    else \
       echo "Unknown mode: $LOG_IO_MODE"; \ 
    fi

　假设我构建出来的镜像tag是 jiafeng/logio:v6

在服务端机器上执行一下指令

# 创建服务端日志目录
mkdir /root/.log.io
 
# 填写服务端配置
cat > /root/.log.io/server.json<EOF
{
  "messageServer": {
    "port": 6689,
    "host": "0.0.0.0"
  },
  "httpServer": {
    "port": 6688,
    "host":"0.0.0.0"
  }
}
EOF
 
# 启动服务端容器
docker run -d -p 6689:6689 -p 6688:6688 --name logio \
  -v /root/.log.io:/root/.log.io \
  jiafeng/logio:v6

启动之后就可以用宿主机的ip：6688访问UI界面了。

接下来我们配置客户端

# 创建配置目录
mkdir -p /root/.log.io/inputs
 
# 创建测试日志目录
mkdir /home/logs
 
# 填写配置文件
cat > /root/.log.io/inputs/file.json <EOF
{
    "messageServer": {
        "port": 6689,
        "host": "192.168.29.130"
    },
    "inputs": [
        {
            "source": "app1",
            "stream": "node1",
            "config": {
                "path": "/home/logs/app1.log"
            }
        },
        {
            "source": "app2",
            "stream": "node1",
            "config": {
                "path": "/home/logs/app2.log"
            }
        }
    ]
}
EOF
 
# 准备一个模拟写日志的脚本
cat > product.sh<EOF
 
#/bin/bash
 
while true
do
sleep 1
echo "$(date +'%Y-%m-%d %H:%M:%S') This is app1 log!" >> /home/logs/app1.log
echo "$(date +'%Y-%m-%d %H:%M:%S') This is app2 log!" >> /home/logs/app2.log
done
EOF
 
# 赋权并启动
chmod u+x prodct.sh && ./product.sh &
 
# 启动客户端容器
docker run -d  --name logio-client \
  -v /root/.log.io:/root/.log.io \
  -v /home/logs:/home/logs \
  -e "LOG_IO_MODE=client" \
  jiafeng/logio:v6
