ConfigGenerator

Kustomization Generator

Generate kustomization.yaml files with resources, bases, patches, labels, namespaces, ConfigMap generators, Secret generators, and Helm support.

Output:A ready-to-use configuration file for Kustomization with best practices applied.

Quick Summary

Use a Kustomization Generator to create kustomization.yaml for declarative management of Kubernetes objects using bases, overlays, and patches.

What is this tool?

Kubernetes uses YAML to define its resources. Using a generator ensures your syntax is correct and you don't miss important fields.

How to Use This Tool

  1. Input your resource name and metadata.
  2. Configure the specific properties.
  3. Review the generated YAML.
  4. Copy the YAML or download it as a file.

What This Tool Generates

  • manifest.yaml

Security Notes

  • Always review generated YAML before applying it to production clusters.
  • Use RBAC to restrict who can apply manifests.

Testing Instructions

  • Test your generated manifests against your cluster before deploying:
  • kubectl apply --dry-run=server -f manifest.yaml

Frequently Asked Questions

What is Kustomization?
Kustomize introduces a template-free way to customize application configuration that simplifies the use of off-the-shelf applications. It's built directly into kubectl.
How do I build a kustomization?
Run `kubectl kustomize <directory>` to output the generated YAML, or `kubectl apply -k <directory>` to apply it directly to the cluster.
What are Kustomize bases and overlays?
A base is a directory containing a kustomization.yaml and resources. An overlay is another directory that uses the base as a resource and patches it for specific environments (e.g. dev, prod).
How do I generate a ConfigMap with Kustomize?
Use the `configMapGenerator` field in kustomization.yaml to generate a ConfigMap from literal values or files. Kustomize appends a hash to the name to force pod rollouts when the config changes.

How We Keep Your Configs Safe & Valid

Built-in Error Checking

Every file is checked against official rules. We catch missing fields and bad syntax. YAML indentation errors are flagged right away. Kubernetes, Terraform, and Docker specs are all covered. API versions and labels are verified too. You get valid output every time you generate.

100% Private & Local

All tools run in your browser only. Your API keys never leave your machine. We do not use any tracking scripts. No data is sent to any server. Passwords and secrets stay on your device. Crypto operations use the Web Crypto API. Your privacy is fully protected at all times.

Secure Settings by Default

Configs use safe defaults out of the box. Containers run as non-root users. Root filesystems are set to read-only. Dangerous Linux capabilities are dropped. Network policies limit pod-to-pod traffic. TLS 1.3 is enabled for web servers. Security headers are added where needed.

Ready for CI/CD & Git

Output files are ready for your Git repo. Use them with ArgoCD, Flux, or GitHub Actions. Files use clear formatting and comments. Code review is easy for your team. Indentation and key order are consistent. Test in staging before going to production. Every file is clean and well-structured.

Infrastructure as Code

Store configs in Git alongside your code. Terraform modules include typed variables. Backend configs support remote state locking. Outputs work across multiple modules. Ansible playbooks use clear task steps. Chef and Puppet configs are also supported. Every file works with version control tools.

Monitoring & Tracing

Set up Prometheus with auto-discovery rules. Create Grafana dashboards with template variables. Add alerting rules with severity labels. Use OpenTelemetry for trace collection. Forward logs to Loki or Elasticsearch. Connect to Jaeger or Tempo for tracing. Monitor metrics, logs, and traces together.

Container & Docker Safety

Dockerfiles use multi-stage builds for small images. Base images are pinned to exact versions. Dev files are excluded from final images. Health checks are added for orchestrator use. Containers switch to non-root users. Docker Compose uses named volumes and networks. Resource limits are set in deploy configs.

Multiple Output Formats

Export as YAML, JSON, HCL, or TOML. Kubernetes uses YAML with proper separators. Terraform uses HCL with correct escaping. JSON output has consistent indentation. Copy to clipboard with one click. Preview output with syntax highlighting. Line numbers help you review quickly.
