502 bad gatway Error while access Web fluffi (http://localhost:8880). about fluffi HOT 5 CLOSED

1. It looks as if the fluffi_gm is not started due to the missing GlobalManager binary: fluffigm_1 | standard_init_linux.go:211: exec user process caused "no such file or directory"
2. I am not sure polemarch is working as intended ("already initialized, retrying"-loop)

Both, however will not lead to a "502 bad gateway" error. I am not sure whether the moment in which you requested the web site is included in the log above. Could you please do another run and mark the moment in which you try to open web.fluffi in the log? Like this:

...
----FIRST ATTEMPT TO OPEN web.fluffi
.....
----SECOND ATTEMPT TO OPEN web.fluffi

from fluffi.

I think for debuggung purposes it would be better to detach from the containers and look at the logs separately.
You can specify which output logs to view when you run docker-compose logs -f <servicename[s]> - then you only get the specified containers log output, not everything mangled together. The -f parameter for the logs command works the same way it does in tail, it follows new output while looking at the logs - not to be confused with the docker-compose parameter of the same name, which specifies the compose file to use.

So the service in question (webinterface) can be viewed with

docker-compose -f /srv/fluffi/docker-compose.yaml logs -f fluffiweb

from fluffi.

@TomSie Please have a look below while accessing web.fluffi. Also I'm able to access polemarch but not sure about GlobalManger issue. I have already copied GlobalManager as sggusted in doc.

well, I think the central part here is

Lost connection to MySQL server during query

Can you connect to db.fluffi?

from fluffi.

closing issue due to bypass this issue
