how to compensate for lack of automatic memory-usage.txt file on CircleCI 2.0 (thanks @bellkev @heug)

memory-usage-2.sh

#! /bin/bash

set -eu

print_usage() {
  outer_containers=$(sudo docker ps | grep "circleci/picard" | awk '{print $1}')
  if [[ $outer_containers ]]; then
    for outer_container in $outer_containers; do
      build_uri=$(sudo docker inspect $outer_container --format '{{.Config.Labels.build_uri}}')
      echo "Job: $build_uri"
      procs=$(ps -eo pid,cgroup | grep $outer_container | awk '{print $1}' | tr '\n' ','| sed 's/,$//')
      ps -o pid,rss,cmd --sort=-rss --pid $procs
    done
  else
    echo "No jobs running"
  fi
}

while true; do
  date +"%F %T UTC"
  print_usage
  sleep 10
done
