Many organizations adopt cloud native development practices with the dream of shipping features faster. Although the technologies and architectures may change when moving to the cloud, the fact that we all still add the occasional bug to our code remains constant. The snag is that many of your existing local debugging tools and practices can’t be used when everything is running in a container or on the cloud.
Easy and efficient debugging is essential to being a productive engineer, but when you have a large number of microservices running in Kubernetes the approach you take to debugging has to change. For one, you typically can’t run all of your dependent services on your local machine. This then opens up the challenges of remote debugging (and the associated fiddling with debug modes and exposing ports correctly). However, there is another way. And the CNCF Telepresence tool enables this path.
