运行gl.canvas.set_target('ipynb')
会在docker容器中抛出exeption。
即使gl.canvas.set_target('ipynb', port=28892)
其中28892是开放端口,错误也保持不变。

看起来更像是一个码头/龙卷风问题而不是graphlab问题,因为在主机上同样的命令也能正常工作。
我使用以下命令启动了我的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?
答案 0 :(得分:5)
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。
在容器启动时,我的/ etc / hosts包含以下行:
127.0.0.1 localhost
::1 localhost ip6-localhost ip6-loopback
我必须将它们改为:
127.0.0.1 localhost
::1 ip6-localhost ip6-loopback
答案 1 :(得分:0)
ForcaeLuz的另一个答案是好的,但只能治疗症状。
似乎最近在this commit中的Tornado中已修复该问题,其中的注释非常有用(例如Docker的默认配置如何引起这种情况)。
在某些系统上(最明显的是使用默认配置的docker),ipv6被部分禁用:socket.has_ipv6为true,我们可以创建AF_INET6套接字,并且getaddrinfo(“ localhost”,...,AF_PASSIVE)解析为:: 1 ,但绑定时会出现错误。
它尚未发布(截至撰写本文时),但可以从其主分支(例如,通过运行
pip install --upgrade git+https://github.com/tornadoweb/tornado.git@master#egg=tornado
(或类似),或等待(我认为)应包含此更改的6.1.0版本。在其他一些使用龙卷风的项目中进行了尝试,并在Docker中遇到问题时,一切都很好。
