5 Tips for Making Containers Faster

One of the selling points of containers is that containerized applications are generally faster to deploy than virtual machines. Containers also usually perform better. But just because containers are faster by default than alternative infrastructure doesn’t mean that there are not ways to make them even faster. You can go beyond the defaults by optimizing Docker container image build time, performance and resource consumption. This post explains how. Defining “Faster” Before we delve into Docker optimization tips, let me first explain what I mean when I write about making containers “faster. Read More…

Terraform is an excellent tool for managing infrastructure as code, and many of our users already make use of it elsewhere in their environments. Using this module along with either GCE or AWS to orchestrate Rancher gives you the ability to define the entirety of the stack—from the application layer being managed by Docker Compose or Kubernetes resource YML in Rancher all the way down to the servers and networks in the Terraform plan.
