Weave + Docker for Mac: The bridge between local and remote services
Integration testing and debugging many microservices can be painful. Often, I need to debug a service on a staging environment. This article shows how we use Docker for Mac with Weave (an overlay network) to connect our local machine to our remote staging environments.
In my workflow, I usually create a WIP git commit, push it to staging, and try to debug with the Ubuntu server’s limited tools. I could set up a bunch of SSH tunnels to connect to all the remote services, but our stack changes too frequently and finding IP addresses for each service is a pain. My dev machine is a Mac, so most of the tools we use locally don’t work on Linux.
I wanted something better that would speed up my dev and debugging flow. The first thing I tested with the Docker for Mac beta was Weave integration. Weave creates an overlay network to connect containers across multiple hosts together, which is very useful when distributing containers across a Swarm cluster.

Dropping Webhooks
Auto-deploy is a really important feature of our product here at Runnable. It takes the tedium out of managing multiple testing and development environments. Via a GitHub webhook, we listen to push events that occur on our customers’ repositories and automatically deploy the changes to the Runnable Sandbox application.
A few weeks ago I ran into a situation that was rather troubling: a new branch I created didn’t show up in the app. Wondering if I had accidentally botched the command, I rechecked my terminal and confirmed that I had successfully pushed the branch to GitHub. A bit puzzled by the state of things, I decided to dig in and investigate the problem.

Testing your app on a budget
Despite our best efforts bugs will be with us forever. Human error, limited data sets, and perhaps most importantly time keep us from finding all the issues. We must try. So we deploy numerous approaches to finding them. Which reminds me of the saying about advertising attributed to John Wanamaker.

Running Runnable on Runnable
It’s an exciting time for us. Our team adopted Docker early when building Runnable CodeSnippets, a collaborative place for developer learning. From there we took on the bigger challenge of providing development and test environments for teams. All while in the backdrop of the growth and early adoption of the container ecosystem.
