Docker 이미지 다중 아키텍처(Multi-Architecture) 빌드 가이드 Docker build Docker 이미지를 빌드할 때는 기본적으로 빌드하는 머신의 CPU 아키텍처(Platform)에 맞춰 빌드됩니다. 이는 Docker의 기본 동작이며, 호스트 시스템의 아키텍처와 일치하는 이미지를 생성합니다. 아키텍처의 중요성: 컨테이너는 호스트 OS의 커널을 공유하지만, CPU 아키텍처에 맞는 바이너리가 필요합니다. 예를 들어, ARM64용으로 빌드된 이미지는 AMD64 시스템에서 직접 실행할 수 없습니다. macOS arm64 테스트 $ uname -a Darwin glass 20.6.0 Darwin Kernel Version 20.6.0: Wed Jun 23 00:26:27 PDT 2021; \ root:xnu-7195.141.2~5/RELEASE_ARM64_T8101 arm64 # Dockerfile FROM alpine RUN uname -a # no-cache, plain output $ docker build . -t cdecl/alpine --no-cache --progress=plain ... #5 [2/2] RUN uname -a #5 sha256:bb35af1757e6b002e99344411e8e8fc700e8760f29f48b4de0f0bb7276ead75d #5 0.238 Linux buildkitsandbox 5.10.25-linuxkit #1 SMP PREEMPT Tue Mar 23 09:24:45 UTC 2021 aarch64 Linux #5 DONE 0.2s ... $ docker image inspect cdecl/alpine -f '{{.Architecture}}' arm64 Platform 변경하여 이미지 빌드 Docker는 --platform 플래그를 통해 타겟 아키텍처를 지정할 수 있습니다.

Introduction https://github.com/yhirose/cpp-httplib{:target="_blank"} A C++11 single-file header-only cross platform HTTP/HTTPS library. This is a multi-threaded ‘blocking’ HTTP library header-only 라이브러리로 Server와 Client Http 지원 SSL을 위한 OpenSSL 필요 cpprestsdk비해 가볍고, 쉽게 사용 가능 Httplib package install (w/ vcpkg) https://github.com/microsoft/vcpkg{:target="_blank"} vcpkg 통해서 패키지 설치 header-only로 바로 사용가능하나 OpenSSL 필요시 패키지 설치가 용이 # --triplet=x64-windows-static $ vcpkg.exe install cpp-httplib openssl --triplet=x64-windows-static ... The package cpp-httplib:x64-windows-static is header only and can be used from CMake via: find_path(CPP_HTTPLIB_INCLUDE_DIRS "httplib.h") target_include_directories(main PRIVATE ${CPP_HTTPLIB_INCLUDE_DIRS}) The package openssl is compatible with built-in CMake targets: find_package(OpenSSL REQUIRED) target_link_libraries(main PRIVATE OpenSSL::SSL OpenSSL::Crypto) Json test https://github.com/nlohmann/json{:target="_blank"} $ vcpkg.exe install nlohmann-json --triplet=x64-windows-static The package nlohmann-json:x64-windows-static provides CMake targets: find_package(nlohmann_json CONFIG REQUIRED) target_link_libraries(main PRIVATE nlohmann_json nlohmann_json::nlohmann_json) Sample code HTTPS 호출을 위해 CPPHTTPLIB_OPENSSL_SUPPORT 매크로가 정의 되어 있어야 함 정의하지 않고 HTTPS 호출시 : 'https' scheme is not supported. using namespace std; std namespace 노출시 byte 타입 정의 모호함으로 인한 에러 발생 표준 라이브러리 보다 먼저 선언되던가 using namespace std;를 피해야 함 ‘byte’: 모호한 기호입니다. #define CPPHTTPLIB_OPENSSL_SUPPORT #include <httplib.h> #include <iostream> using namespace std; #include <nlohmann/json.hpp> using json = nlohmann::json; void HttpRequest() { httplib::Client cli("https://httpbin.org"); { auto resp = cli.Get("/get"); cout << "status: " << resp->status << endl; cout << resp->body << endl; } { auto resp = cli.Post("/post"); cout << "status: " << resp->status << endl; cout << resp->body << endl; auto js = json::parse(resp->body); cout << "User-Agent: " << js["headers"]["User-Agent"] << endl; } } int main() { try { HttpRequest(); } catch (exception &e) { cerr << e.what() << endl; } catch (...) { cerr << "catch ..." << endl; } return 0; } CMakeLists.txt cmake_minimum_required(VERSION 3.11) project(main) set(CMAKE_CXX_STANDARD 17) add_executable(main main.cpp) target_compile_options(main PRIVATE /MT) find_package(OpenSSL REQUIRED) target_link_libraries(main PRIVATE OpenSSL::SSL OpenSSL::Crypto) find_path(CPP_HTTPLIB_INCLUDE_DIRS "httplib.h") target_include_directories(main PRIVATE ${CPP_HTTPLIB_INCLUDE_DIRS}) find_package(nlohmann_json CONFIG REQUIRED) target_link_libraries(main PRIVATE nlohmann_json nlohmann_json::nlohmann_json) $ mkdir build && cd build # x64-windows-static $ cmake -G "Visual Studio 16 2019" -A x64 .. -DCMAKE_TOOLCHAIN_FILE=D:/Lib/vcpkg/scripts/buildsystems/vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows-static Build & Run # build $ echo cmake --build . --config Release > make.bat $ make.bat # run $ Release\main.exe status: 200 { "args": {}, "headers": { "Accept": "*/*", "Cache-Control": "max-stale=0", "Host": "httpbin.org", "User-Agent": "cpp-httplib/0.9", "X-Amzn-Trace-Id": "Root=1-611dba9f-0bdb46bb04c05b410da75cf4", "X-Bluecoat-Via": "ce2cfae06b3f12b4" }, "origin": "xx.xx.xx.xx", "url": "https://httpbin.org/get" } status: 200 { "args": {}, "data": "", "files": {}, "form": {}, "headers": { "Accept": "*/*", "Content-Length": "0", "Host": "httpbin.org", "User-Agent": "cpp-httplib/0.9", "X-Amzn-Trace-Id": "Root=1-611dba9f-091d99a41e5b3c023550162f", "X-Bluecoat-Via": "ce2cfae06b3f12b4" }, "json": null, "origin": "xx.xx.xx.xx", "url": "https://httpbin.org/post" } User-Agent: "cpp-httplib/0.9"
