tornado/graphlab无法在docker中分配请求的地址

Question

gl.canvas.set_target('ipynb')在docker容器中的exeption之后运行抛出.

即使gl.canvas.set_target('ipynb', port=28892)28892是开放端口,错误也保持不变.

它看起来像是一个码头/龙卷风问题而不是graphlab问题,因为在主机上同样的命令有效.

我使用以下命令启动了docker容器:

sudo docker run -it -v /path/to/data:/root/data \
    -v ~/code/work/src:/root/src \
    -p 8888:8888 -p 28892:28892 company/graphlab \
    /bin/bash -c "source activate gl-env && jupyter notebook --notebook-dir=~/src --ip='*' --port=8888 --no-browser"

有没有办法找出这个端口,以便我可以打开它或任何其他方式来解决这个问题？

编辑/ etc/hosts文件(在容器内)只包含localhost的1个ip地址值为我解决了这个问题.它只适用于在正在运行的容器上编辑它.在构建图像时编辑它并不能解决问题.

在从容器启动时,我的/ etc/hosts有以下行:

127.0.0.1   localhost
::1 localhost ip6-localhost ip6-loopback

我不得不改变它们:

127.0.0.1   localhost
::1 ip6-localhost ip6-loopback
