DevOps operational guides
Practical guides for Git, CI/CD, Docker, Terraform, Kubernetes, and secure delivery.
Git and GitHub
Inspect Git changes, diffs, and history
Use status, diff, log, and show to understand a change before review or deployment.
Read guide →Use .gitignore and keep secrets out of Git
Ignore local-generated files, confirm what remains tracked, and respond correctly if a credential was committed.
Read guide →CI/CD
Diagnose a failed CI/CD pipeline and its artifacts
Trace a change through build, checks, artifacts, and deployment; find the earliest meaningful error and rerun with a hypothesis.
Read guide →CI/CD and security
Manage CI variables and secrets safely
Scope credentials to the smallest job and environment, avoid log or artifact leaks, and rotate exposed values.
Read guide →Docker and containers
Inspect Docker containers and read their logs
Inspect running and exited container state, read recent output, and check termination details without exposing configuration secrets.
Read guide →Understand Docker image tags, registries, and non-root users
Read the full image reference, distinguish tags from digests, and inspect the configured container user.
Read guide →Understand Docker volumes and container networking
Inspect mount sources and network membership, and distinguish published ports from application listeners.
Read guide →Terraform and infrastructure as code
Run Terraform init, validate, plan, and apply safely
Format and validate configuration, inspect a saved plan, and apply only the reviewed changes in the intended workspace.
Read guide →Protect Terraform state, variables, modules, and secrets
Understand state contents, review module inputs and outputs, and detect configuration drift without exposing secret values.
Read guide →Kubernetes
Inspect Kubernetes Pods, Deployments, and Services
Confirm cluster context, compare desired and observed replicas, then inspect service selectors, configuration references, and endpoints.
Read guide →Troubleshoot Kubernetes probes and resource limits
Distinguish startup, readiness, and liveness failures from resource pressure and scheduling limits.
