[jira] [Commented] (MESOS-198) WebUI fails when the master is set
to any ip other than localhost
[ https://issues.apache.org/jira/browse/MESOS-198?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13283421#comment-13283421 ]
Jessica J commented on MESOS-198:
---------------------------------
Yes, I had the same problem. webui/master/index.tpl has the URL hardcoded to http://localhost. I changed it to instead use "http://" + master_ip; then I modified webui/master/webui.py, setting master_ip to the IP I used for my master and passing master_ip=master_ip as an extra context variable to the index template. My index page then loaded correctly.
So I think the solution is something along the following lines: when the webui script is started, pass an additional option master_ip (along with master_port, etc.) to match whatever IP the master is bound to, which will then also get passed to each template for rendering. I'm guessing the same thing will need to be done with the slave files (e.g., slave_ip).
This is the first time I've tried to use the WebUI, so I haven't tested my solution completely. It seems like there ought to be a better solution, but at the very least this is one that I'm fairly certain will work.
