    离线环境来从现场获取docker的pprof信息步骤

    获取go的镜像

    ```shell
    while read img;
    do docker run --rm --entrypoint go $img version 2>/dev/null | grep -qw version && { echo $img;break; };
    done < <(docker images --format '{{.Repository}}:{{.Tag}}')
    ```

    转发docker的sock成tcp

    ```shell
    socat -d -d TCP-LISTEN:8081,fork,bind=0.0.0.0 UNIX:/var/run/docker.sock
    socat -d -d TCP-LISTEN:18081,fork,bind=0.0.0.0 TCP4:1.1.1.1:30000
    ```

    镜像起容器获取pprof文件

    ```shell
    go tool pprof http://1x.xxx.45.162:8080/debug/pprof/goroutine

    # 或者
    curl -s http://1x.xxx.45.162:8080/debug/pprof/goroutine > test.goroutine
    # 然后把`test.goroutine`拿回来转换成pdf
    yum install -y graphviz
    go tool pprof --pdf test.goroutine > goroutine.pdf

    go tool pprof -http=0.0.0.0:8080 test.goroutine
    ```
