自2021年11月19日起，Docker宣布將不再允許中國大陸用戶訪問其鏡像服務，這一決定引起了廣泛的關注和反響。

根據Docker官方發布的聲明，這一政策的出臺主要是為了遵守美國出口管制法規，但對于中國用戶來說，這無疑是一次重大的打擊。

參考聲明：
Dear Docker community,
As a global company, Docker must comply with all applicable export control laws and regulations, including those of the United States of America. To that end, we have made the decision to no longer allow access to Docker’s public registry in China. This includes both the hub.docker.com website, as well as the registry endpoints hosted on both AWS and Azure in China. This decision will become effective on November 19th, 2021. Please be aware that if your account primarily accesses Docker from China, your account will be impacted by this change.
We understand this is a significant step that may impact many of our users in China. It is important that you have the resources available to minimize the potential impact to your container workflows, and we want to help you through this transition. Therefore, we have put together the following guidance to assist you during this period.

隨著Docker在中國市場的日益普及，許多中國用戶已經將其作為首選的容器技術，以滿足不同應用程序的封裝和運行需求。然而，面對此次政策的改變，許多用戶不得不重新尋找替代方案，以確保其生產環境的正常運作。

盡管Docker已經表示將在特定的企業客戶中提供服務，但對于個人和小型企業來說，這一政策的影響可能會更加重要。因此，在未來的一段時間里，我們需要繼續關注相關發展，以尋找并采用更加合適的解決方案，以面對此次變化帶來的挑戰。
