Pre-optimize images by downsampling. This greatly simplifies the task of finding hosts with sufficient resources and running those hosts at high utilization, all while achieving other operational goals such as always running applications fully in RAM, avoiding swap memory. Luckily there's a cheap and easy way to work around this issue. Alternatively, you can set the flag in an environment variable, such as this: You must set the following variable in your environments configuration file if you wish to change Node.js memory limitations for your entire environment (.bashrc,.bash profile,.zshrc, and so forth).
