控制台应用静态库编译

cmake_minimum_required(VERSION 3.14)
project(CommaSdkActivator)
 
set(CMAKE_CXX_STANDARD 11)
 
 
# yum install glibc-static libstdc++-static
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -static")
 
if(WIN32)
  set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} /SUBSYSTEM:WINDOWS,5.01")
endif()
 
if(MSVC)
    # Use the static C library for all build types
    foreach(var

        string(REGEX REPLACE "/MD" "/MT" ${var} "${${var}}")
      endif()
    endforeach()
endif(MSVC)
 
add_executable(CommaSdkActivator main.cpp)

指定ndk的库输出

defaultConfig {
applicationId “com.commaai.facesdkdemo”
minSdkVersion 19
targetSdkVersion 30
versionCode 1
versionName “1.0”

testInstrumentationRunner “androidx.test.runner.AndroidJUnitRunner”

ndk {
abiFilters “armeabi-v7a”
}
}

Android线程异步处理

private ExecutorService executorService;
private Future mFutureBitmapRunnable;
 
第一步:
this.executorService = Executors.newSingleThreadExecutor();
第二步:
on camera thread callback,do like below.
public void takePhoto(ImiDevice.ImiFrame frame) {
            if (mFutureBitmapRunnable != null && !mFutureBitmapRunnable.isDone()) {
                return;
            }
            ByteBuffer buf = frame.getData();
            buf.position(0);
            final byte[] rgb24 = new byte[buf.remaining()];
            buf.get(rgb24);
            final int width = frame.getWidth();
            final int height = frame.getHeight();
            mFutureBitmapRunnable = executorService.submit(new Runnable() {
                @Override
                public void run() {
                    //to do
                }
           });
}

快速构建istio的测试容器

第一步:以nginx的容器为测试
build.sh脚本内容如下。

#!/bin/sh
 
path_current=`pwd`
path_script=$(cd "$(dirname "$0")"; pwd)
 
ver=$1
if [ "$ver" == "" ]; then
   echo "should like: build.sh v2"
   exit
fi
 
docker rmi ngtest:${ver}
docker stop mynginx
docker rm mynginx
docker run --name mynginx -d nginx:1.17.8
docker cp ./default.conf mynginx:/etc/nginx/conf.d/default.conf && docker commit mynginx ngtest:${ver}
docker stop mynginx
docker rm mynginx
echo "----------------list ngtest image---------------------"&&docker images|grep ngtest

与脚本同级目录下的default.conf配置文件如下:

server {
    listen       80;
    listen  [::]:80;
    server_name  localhost;
 
    location /test {
        default_type application/json;
        return 200 "vm4 - v2 - time:$date_gmt - remote:$remote_addr";
    }
 
    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }
 
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

第二步:

service的三种类型

Kubernetes的service有三种类型:ClusterIP,NodePort,LoadBalancer

apiVersion: v1
kind: Service
metadata:
  name: ngtestsvc
spec:
  type: NodePort  【不指定,默认为ClusterIP】
  ports:
  - port: 1080
    targetPort: 80  【不指定时,默认与port一致】
    #nodePort: 31080 【该端口被强制划分为30000~50000之间,建议由系统自动分配,因为它会产生冲突的。】
    name: http
  selector:
    app: ngtestapp
