There's a lot of custom packages under https://gitlab.example.net/groups/example - I like to clone them all down to scan them every now and then.

First create an access token - https://gitlab.example.net/profile/personal_access_tokens .

Store it locally:

$ cat ~/.netrc 
machine gitlab.example.net

before_script:
  # set up ssh key - it's defined under secret variables on
  # https://***/*/*/settings/ci_cd
  - mkdir /root/.ssh
  - echo "Host example.net" > /root/.ssh/config
  - echo "StrictHostKeyChecking no" >> /root/.ssh/config
  - echo "$SSH_PRIVATE_KEY" | tr -d '\r' > /root/.ssh/id_rsa
  - chmod 0700 /root/.ssh
  - chmod 0600 /root/.ssh/*

Raising the buffers is the default reaction to the nginx error upstream sent too big header while reading response header from upstream with php-fpm and fcgi, but it doesn't solve the problem, just makes it harder to hit.

Put this in a .php file somewhere:

<?php
for ($i = 0; $i<$_GET['iterations']; $i++)
        error_log(str_pad("a", $_GET['size'], "a"));
echo "got here\n";

This is not a complete, comprehensive guide, but it is meant to be a start in the right direction.

From the memcached working directory (where ever you cloned the repo):

$ docker run -it -v "$PWD:/memcached" --name "memcache-dev" ubuntu:artful bash

This creates a container named "memcache-dev" based on the artful tag of the ubuntu image from hub.docker.com.
