I'm using the web serving benchmark and all the components are on the localhost. I start them using the following commands:
docker run --security-opt seccomp:unconfined -dt --net=host --name=mysql_server cloudsuite/web-serving:db_server localhost
docker run --security-opt seccomp:unconfined -dt --net=host --name=memcache_server cloudsuite/web-serving:memcached_server
docker run --cap-add SYS_PTRACE --security-opt seccomp:unconfined -dt --net=host --name=web_server cloudsuite/web-serving:web_server /etc/bootstrap.sh
docker run --security-opt seccomp:unconfined --net=host --name=faban_client cloudsuite/web-serving:faban_client localhost
Then, the benchmark hung and never finish. I login to the web_server docker and examine the PHP-FPM master process using strace -f -s 2000 -o app2.trc -p 37 and I see
root@kettle:/usr/share/nginx/html# strace -f -s 2000 -o app2.trc -p 37
Process 37 attached
Process 15234 attached
Process 15235 attached

Process 15239 attached
Process 15240 attached
Process 15241 attached
^CProcess 37 detached
Process 15240 detached
Process 15241 detached
That's an indication of processes under PHP-FPM dying quickly. Then, I look into the trace app2.trc and
I see
15234 write(2, "NOTICE: PHP message: PHP WARNING: 2018-04-21 19:55:45 (UTC): \"mm

If I run strace command a little bit longer and I can see other warning messages

I think there might be some problem with my setup but I cannot figure out where.
Thanks for the help!

Hi,
Please check file settings.php in web_server container /usr/share/nginx/elgg/elgg-config, which is also specified in folder files/settings.php and make sure the $CONFIG->dbhost = '127.0.0.1' or whatever the ip of your db server is. "localhost" wouldn't work.
Alternatively, please try to remove settings.php and go through the ELGG registration manually through a web browser by entering the details of the mysql database.
