Hi
I resolved this issue.
I find a solution for ERROR GnuTLS recv error (-110),that is add 3 commands in Dockfile as below:

RUN apt-get install gnutls-bin
RUN git config --global http.sslVerify false
RUN git config --global http.postBuffer 1048576000

Then the error disappeared.I will continue with the installation and there may be other problems, but this issuecan be closed,thanks.
