Imagine the following scenario: you have multiple backend containers that run your web application, and a few nginx containers that proxy all requests to the backend containers.Now, there’s a new release of the web application that must be deployed, which means new backend containers need to be built and deployed.The 30-year-old chatted with Jay Cutler has one fine Met Gala coverage on Monday and then head home for moving day on Tuesday!And, thanks to his wife Kristin Cavallari, we got a peek at the American athlete's buns of steel on Instagram.It is therefore very important to first select the configuration files that should not be automatically updated.
Kristin has made some enemies in LA, but now that her summer romance with Justin is fading, she wants to make friends.
After they are deployed, the nginx configuration needs to change to point to the new backend containers. Do you change the its configuration, build a new container and deploy it?
What if there was a way for you to automatically detect the changes on the backend service and dynamically update nginx? Rancher-Gen is a Python utility that listens for service changes in Rancher and renders a user-specified Jinja2 template.
Introduction Docker and Rancher have made it far easier to deploy and manage microservice-based applications.
A key challenge, however, is managing the configuration of services that depend on other dynamic services.
