在作为主机的EC2 SUSE SLES 12.3 Linux实例上，我已经安装了docker。 我想为SUSE 12.3创建自定义docker映像。我已遵循官方文档https://www.suse.com/documentation/sles-12/singlehtml/book_sles_docker/book_sles_docker.html
我创建了一个Docker File，其中包含类似的说明
RUN zypper --gpg-auto-import-keys ref -s
RUN zypper ref -s
RUN zypper in gedit
但是每次执行docker构建时，我都会得到以下错误提示
Refreshing service 'container-suseconnect'.
Warning: Skipping service 'container-suseconnect' because of the above error.
All services have been refreshed.
Warning: There are no enabled repositories defined.
Use 'zypper addrepo' or 'zypper modifyrepo' commands to add or enable repositories.

我已经用Google搜索上述问题，并执行了Docker container-suseconnect failing中提到的以下步骤。我已经安装了博客中提到的必需证书。
我指的是AMAZON在孟买地区提供的SMT服务器。
Docker文件内容
FROM registry.suse.com/suse/sles12sp3
#Import the crt file of the SMT server
ADD http://smt-ec2.susecloud.net/smt.crt /etc/pki/trust/anchors/smt.crt
RUN update-ca-certificates
RUN zypper --gpg-auto-import-keys ref -s
RUN zypper in gedit
Run zypper ref -s
#RUN zypper -n in vim
我需要在根据SUSE映像创建的docker容器中执行zypper指令
