How can I change some field of Graylog configure in MongoDB in this image? about graylog2-images

[mariussturm]

Could you please provide some more context? What exactly do you want to achieve? Accessing the mongodb directly is almost always the wrong approach.

My graylog server is set as a vm in my laptop. And the IP address for the graylog vm cannot be static due to my network environment. I found that there is always an invalid IP address(the first IP address when I begin running graylog from this image) hanging around when I did a "graylog-ctl list-servers".
This doesn't bother me for now because I am only playing around with one node. I wonder if I try to run a multinode environment, this will be an issue. So I wish I could remove this IP address from the servers list or something.
I try to edit some conf file under /opt/graylog/conf but still, that IP address won't go away even my vm's IP keeps changing from time to time.

Example:
If I try,
$ graylog-ctl list-servers
_...100
*__._.***.123
123 is current IP for graylog. 100 is the IP when I first run this image.

You can simply re-run graylog-ctl reconfigure to update all configurations to the new IP

Yup, actually I did this when my graylog vm IP changes. But still, the old one stays there for some reason when I try "list-servers".
Btw, the reconfigure command will automatically detect the new IP and changes the conf? Because I usually manually change the conf file with new IP address then run reconfigure command.

[mariussturm]

Yes it renders all configuration files. So if you first edit the file manually and then run reconfigure your changes are overwritten.
But the command takes notice of a change IP address and adopt the configuration where possible.

Sounds good enough for me now. Should close this one. Thank you so much!
