ERRO [0043]无法拨打gRPC：无法升级到h2c，收到501 [英] ERRO[0043] failed to dial gRPC: unable to upgrade to h2c, received 501

问题描述

今天，当我尝试使用 docker build -t myimage1构建我的Dockerfile时。我收到此错误：

When I tried building my Dockerfile with docker build -t myimage1 . today I got this error:

ERRO[0043] failed to dial gRPC: unable to upgrade to h2c, received 501
context canceled

虽然是几周前，但我已经成功构建了此图像。我不确定Docker是否已同时更新。

I have successfully built this image before although it was a couple of weeks ago. I am not sure whether Docker has been updated in the meantime.

我在<上发现了一个类似的错误（尽管不尽相同-我是0043时是错误0044）。 a href = https://stackoverflow.com/questions/55308947/erro0044-failed-to-dial-grpc-cannot-connect-to-the-docker-daemon/58731161#58731161> ERRO [0044]拨号失败gRPC：无法连接到Docker守护程序

推荐答案

如果您刚刚启动Docker守护程序，请等待一段时间，然后再试一次。

If you just started Docker daemon, please wait for some time and try again.
