Failed to create extended docker image with self customized Dockerfile based on x11docker/deepin. about dockerfile-x11docker-deepin

If the deepin image is not on your system already, x11docker pulls it from docker hub after asking you for permission.
The deepin image on docker hub is an automated build from the Dockerfile in this repository.

You can also pull the image with docker pull x11docker/deepin and run x11docker afterwards.

(You could as well build the image yourself using the Dockerfile with the docker build command.
E.g. docker build -t x11docker/deepin /path/to/Dockerfile/
In that case you don't need to trust the image on docker hub.)

Is this done/managed by continuous integration system? I mean, if you submitted any changes, the image will be re-generated/updated automatically? If so, what's the CI settings used by you for this repo?

According to the instructions given by the extending base image, I try to build the deepin-wechat docker image based on x11docker/deepin shown as below:

The 127.0.0.1:8080 is local working http proxy for docker set by me. See the following testing result for more info:

Any hints for this problem?

In that case you don't need to trust the image on docker hub.)

I have learned that the speed ​​limit will be imposed on docker hub for image pulling, so for the huge docker image, may be the most efficient way is to build it this way.

I mean, if you submitted any changes, the image will be re-generated/updated automatically? If so, what's the CI settings used by you for this repo?

If I change the github repository, the image is rebuilt automatically. I did a setting on docker hub that allows docker hub to access the github repository and to watch for changes.
Compare: https://docs.docker.com/docker-hub/builds/
Alternatively, I can send a command to force a rebuild. It is called a webhook: https://docs.docker.com/docker-hub/webhooks/

According to the instructions given by the extending base image, I try to build the deepin-wechat docker image using x11docker/deepin as the base image.

This worked here a few weeks ago. Not sure why it fails on your system. I'll try to reproduce the issue, running a build now. This will take some time due to low bandwidth. I'll report back if the build succeeds or fails here.
EDIT: The build succeeds here. Likely it will help to change the repository mirror as described below and in #7 .

I have learned that the speed ​​limit will be imposed on docker hub for image pulling, so for the huge docker image, may be the most efficient way is to build it this way.

If you want to build the entire x11docker/deepin base image yourself, you might want to change the deepin mirror repository. In the Dockerfile:

# choose a mirror
#RUN echo "deb http://packages.deepin.com/deepin/ lion main non-free contrib" > /etc/apt/sources.list
RUN echo "deb http://mirrors.kernel.org/deepin/  lion main non-free contrib" > /etc/apt/sources.list
#RUN echo "deb http://ftp.fau.de/deepin/          lion main non-free contrib" > /etc/apt/sources.list

In China the fastest mirror should be the first one, so change to:

# choose a mirror
RUN echo "deb http://packages.deepin.com/deepin/ lion main non-free contrib" > /etc/apt/sources.list
#RUN echo "deb http://mirrors.kernel.org/deepin/  lion main non-free contrib" > /etc/apt/sources.list
#RUN echo "deb http://ftp.fau.de/deepin/          lion main non-free contrib" > /etc/apt/sources.list

You could as well add this in your extended Dockerfile, like:

FROM x11docker/deepin
RUN echo "deb http://packages.deepin.com/deepin/ lion main non-free contrib" > /etc/apt/sources.list
RUN apt-get update

Closing here, we work on the DNS issue in #7 .
