解决Dockerfile中git clone containerd失败：'gnutls_handshake() failed'错误

在Dockerfile中使用git clone命令下载containerd源代码时，你可能会遇到以下错误：

fatal: unable to access 'https://github.com/containerd/containerd.git/': gnutls_handshake() failed: The TLS connection was non-properly terminated.

这个错误可能是由于代理设置不正确或者网络连接问题导致的。可以尝试以下几种解决方法：

1. 检查代理设置是否正确，确保代理服务器地址、端口和协议（HTTP或HTTPS）正确。

2. 如果代理设置正确，尝试使用其他网络连接，例如切换到不同的WiFi网络或使用移动数据连接。

3. 如果以上方法都不起作用，可以尝试使用git clone命令手动下载containerd源代码，然后在Dockerfile中使用COPY命令将代码复制到容器中。

4. 如果还是无法解决问题，可以尝试联系GitHub支持团队或网络管理员寻求帮助。

参考代码：

FROM base AS containerd-src
WORKDIR /usr/src/containerd
RUN git init . && git remote add origin 'https://github.com/containerd/containerd.git'
# CONTAINERD_VERSION is used to build containerd binaries, and used for the
# integration tests. The distributed docker .deb and .rpm packages depend on a
# separate (containerd.io) package, which may be a different version as is
# specified here. The containerd golang package is also pinned in vendor.mod.
# When updating the binary version you may also need to update the vendor
# version to pick up bug fixes or new APIs, however, usually the Go packages
# are built from a commit from the master branch.
