Container configuration combines executable build steps, infrastructure references, network locations, image names, and often secret injection. Share a minimal synthetic manifest that preserves the behavior under review while removing operational access and organization-specific details.
Reduce to one failing component
Keep the stage, service, pod, deployment, or policy that reproduces the issue. Remove unrelated containers, generated annotations, status blocks, and large environment sections.
State the Docker, Compose, Kubernetes, Helm, or runtime version. Explain the command used and the expected versus actual result.
Remove cluster and registry secrets
Never share image-pull secrets, kubeconfig credentials, service-account tokens, registry passwords, cloud keys, certificate private keys, or real Secret objects. Replace secret references with clearly synthetic names.
Review private registry hosts, internal service names, cluster identifiers, account IDs, namespaces, and annotations from deployment platforms. Generalize them when they are not necessary to reproduce the behavior.
Practical next step: YAML sharing guide - Preserve indentation and remove credentials.
Preserve semantic structure
Keep YAML indentation, API versions, kinds, selectors, labels, port relationships, volume relationships, and resource units that influence behavior. A redaction that breaks selectors or nesting produces misleading evidence.
Validate the sanitized manifest with the relevant local parser or dry-run command in a safe environment. Syntax highlighting does not validate a deployment.
Share for the review window
Use YAML, Docker, or shell highlighting as appropriate. Choose unlisted access and an expiration matching the support or review period, then move the corrected configuration into version control.
Do not run commands copied from a paste without inspection. Images, scripts, and manifests can change systems even when their text looks routine.
Artifact
| Artifact | Remove | Practical meaning |
|---|---|---|
| Dockerfile | Private registry credentials and internal URLs | Keep the minimal build stage. |
| Compose file | Real environment values and host mounts | Preserve service dependencies. |
| Kubernetes manifest | Secret data, tokens, cluster IDs | Keep selectors and resource units. |
| kubectl output | Tokens, certificate data, user and cluster identity | Keep relevant events and status. |
| Helm values | Operational credentials and customer values | Use synthetic override values. |
