使用 configServer 同一台机器出现多个 image

yyuuttaaoo commented 6 months ago

这个行为是by design的，目前开源的config server对此没有处理好。

liangry commented 6 months ago

严格来说，不算是 bug，应该算主干分支 config server 没有实现的功能，没有心跳管理，已经离线的 agent 记录不能剔除。很久之前，已提交 PR

需要固定可以换成dmi-uuid，下面写了一个实现

optional GetSystemUUID() {

if defined(linux)

{ ifstream uuidFile("/sys/class/dmi/id/product_uuid"); string uuid; if (uuidFile.is_open()) { getline(uuidFile, uuid); uuidFile.close(); return uuid; } return nullopt; }

elif defined(_MSC_VER)

{ HKEY hKey; if (RegOpenKeyEx(HKEY_LOCAL_MACHINE, "SOFTWARE\Microsoft\Cryptography", 0, KEY_READ, &hKey) == ERROR_SUCCESS) { char uuidBuffer[255]; DWORD bufferSize = sizeof(uuidBuffer); if (RegQueryValueEx(hKey, "MachineGuid", nullptr, nullptr, (LPBYTE)uuidBuffer, &bufferSize) == ERROR_SUCCESS) { string uuid(uuidBuffer); return uuid; } RegCloseKey(hKey); } return nullopt; }

else

return nullopt;

endif
