or try install Graylog via app, but its does work

 

Any one know how to install this ?

I came here looking for help on this. First my password was too short. Now It's having permission issues. and I'm not sure how to correct it.

@Maniek2as2 what is in your graylog-graylog-1 log file?

I also have been fighting with trying to get graylog working in an Unraid docker.  Seems to be a combinations of many problems with how ALL the current dockers seem to be built.

For starters, you need other services up and running for Graylog to work.  That being elasticsearch and mongodb.  I have not gotten any of the three docker containers to actually install and 'just work'.  File permissions are trying to run as root, instead of nobody, on all the containers.  There also seem to be some version restrictions betweeh what version of graylog you use and what version of elasticsearch works with it.  Not sure if that is the only problems, but it seems like it may be worth trying to create a container that just includes all three services rolled up together - unfortunatly, I don't know enough about any of them to take this on.

So, just tried the above linked compose method and ended up with the same errors as @GTvert90 .   I don't feel that this particular service should be so strangely difficult to get running.

quick update - it seems the errors I was seeing were due to folder permissions.  For some reason the folders that the containers create don't get set with permissions that those same containers can access.  chmod 777'ing them got the containers to all start up.. I think.. so far... now to actually learn how to USE graylog...

How has it been for you? I am struggling to setup graylog also but all the guides I follow seem to be outdated or not have any fixes for the numerous issues I see.

Unfortunately doing a chmod to 777 on the folders didn't work for me. I still get the errors with the container not being able to change permissions. It's such a strange thing for it to get hung up on.

So, from what I see the .yml is hard coded with the user 'graylog'. Create this user and then edit the graylog container and take a look at the "more settings" > appdata path. I noticed that in some places the container author misspelled 'gray' as 'grey' in the app data set path once you view the edit config of the appdata path. 

You may also need to:
chown -R graylog:users /mnt/user/appdata/graylog/
chmod -R 755 /mnt/user/appdata/graylog/

graylog user is 1100:1100, so setting this to the folders recursively solved my issue.

 

chown -R 1100:1100 /mnt/user/appdata/graylog/
