Homestead does not work if SCTP not installed #54

Open plwhite opened 7 years ago

plwhite commented 7 years ago

Symptoms

Homestead hangs on startup and does not function (hitting bug #49). Underlying cause appears to be that the node kernel does not have SCTP installed (and the OS does not have it available - this is a standard debian release on GKE which may not support SCTP).

Error message is as follows.

    10-11-2016 17:44:47.064 UTC Status diameterstack.cpp:573: Starting Diameter stack

    10-11-2016 17:44:47.066 UTC Status main.cpp:804: Homestead is shutting down

Probable resolution is to disable SCTP.

Impact

Deployment DOA.

Release and environment

GKE.

Steps to reproduce

See above - install on GKE.

Workaround - add the following line to the end of clearwater/base/Dockerfile:

RUN sed -i 's/SCTP_streams.*/No_SCTP;/' /usr/share/clearwater/bin/generic_create_diameterconf

Probably not the right fix, but seems to get past the issue.

Fix for this (and explanation) is available here: https://github.com/Metaswitch/clearwater-infrastructure/pull/395 Not merged yet though as it needs testing.
