Debugging Go: from zero to Kubernetes

Michele Caci

Struggling to troubleshoot isolated Go applications in Kubernetes? Learn how to leverage ephemeral containers and Delve for secure, live debugging without disrupting production traffic.

#1 about 3 min

Core principles of live debugging and data-driven tools

Live execution tracking complements logs and metrics by interacting directly with the running application.

#2 about 2 min

Risks of attaching debuggers in production environments

Disrupting real traffic can cause production incidents unless traffic is properly redirected or conditional breakpoints are applied.

#3 about 3 min

Running local debugging sessions with Delve

Compiling code and attaching to processes via a command-line interface allows direct control over the execution flow.

#4 about 5 min

Configuring dual Docker containers for Go debugging

Isolating the application and debugger into separate containers requires copying source code alongside specific tooling.

#5 about 4 min

Enabling Linux capabilities and sharing process namespaces

The sys_ptrace capability and process namespace sharing allow an isolated debugger container to trace external application processes.

#6 about 3 min

Deploying multi-container debugging pods in Kubernetes

Adding a debugger container directly to a deployment configuration wastes cluster resources if permanently attached.

#7 about 3 min

Using ephemeral containers with kubectl debug

Injecting temporary ephemeral containers into running pods enables on-demand debugging without altering deployment configurations.

#8 about 2 min

Summarizing the Kubernetes live debugging workflow

Live debuggers are complementary tools that augment standard monitoring by exposing underlying runtime execution logic.

#9 about 4 min

Strategies for port forwarding and traffic redirection

Community questions cover local port forwarding, disabling compiler optimizations, and selectively routing test traffic to debug pods.
