DevOps Use Cases
Real-world scenarios where ConfigGenerator tools help teams deliver faster and more reliably.
Microservices Deployment
Package each service as a Docker container, deploy to Kubernetes, and configure Prometheus metrics collection for end-to-end observability.
Infrastructure Provisioning
Use Terraform to provision cloud resources, Ansible to configure servers, and CI/CD to automate the full provisioning pipeline.
GitOps Workflow
Store Kubernetes manifests in Git, use ArgoCD or Flux to sync clusters, and GitHub Actions to validate and promote changes across environments.
Log Aggregation Pipeline
Deploy Fluentd or Vector as DaemonSets to collect node logs, parse structured fields, and ship to Elasticsearch or Loki for centralized search.
Blue-Green Deployments
Run two identical environments behind a load balancer, switch traffic atomically, and roll back instantly if monitoring detects errors.
Security-First CI/CD
Scan Docker images for CVEs, validate Terraform plans against policy, and sign artifacts with Sigstore before promoting to production.
Overview
ConfigGenerator provides free DevOps tools for generating CI/CD pipelines, Kubernetes manifests, Terraform modules, Docker configurations, monitoring setups, and logging pipelines — all validated against production best practices. Our tools cover every stage of the software delivery lifecycle, from infrastructure provisioning to production observability.
How It Works
- Choose a tool category — select from Containers, IaC, CI/CD, Monitoring, or Logging based on your needs.
- Select a generator — pick the specific configuration file you need to produce.
- Configure your settings — use presets or customize fields for ports, security, resource limits, and more.
- Review validation results — fix critical findings and review warnings before using the configuration.
- Copy or download — export the generated config and integrate it into your project.
Best Practices
- Treat all infrastructure and pipeline configs as code — store in Git, review with PRs, and tag releases.
- Use multi-stage Docker builds to separate build-time dependencies from the final runtime image.
- Pin all tool versions (Terraform providers, Kubernetes API versions, GitHub Actions SHA) to prevent breaking changes.
- Implement least privilege: run containers as non-root, scope CI/CD secrets to minimum required permissions.
- Use GitOps patterns for Kubernetes: declarative manifests, automated sync, and audit trails.
- Monitor everything: set up Prometheus scrape targets, Grafana dashboards, and Alertmanager routes before going to production.
- Run config validation in CI: lint Dockerfiles with Hadolint, validate Terraform with fmt/validate, test Ansible with Molecule.
- Use Helm charts or Kustomize overlays for environment-specific Kubernetes configurations instead of duplicating manifests.
Common Mistakes
- Hardcoding secrets in Dockerfiles, CI/CD pipelines, or Terraform variables — use secret managers or encrypted variables instead.
- Running containers as root, which increases the attack surface and can cause file permission issues at runtime.
- Skipping .dockerignore files, which bloats the build context and may leak sensitive files into the image.
- Using 'latest' tags for base images in production, which creates non-reproducible builds and can pull breaking changes.
- Not testing pipeline changes locally before pushing — use tools like act for GitHub Actions or gitlab-ci-local for GitLab CI.
- Ignoring infrastructure drift — run Terraform plan regularly and reconcile state to prevent configuration divergence.
- Over-provisioning Kubernetes resource requests and limits, leading to cluster waste or OOM kills under load.
- Not implementing health checks in container orchestration, causing traffic to route to unhealthy pods during deployments.
Security Recommendations
- Always scan Docker images for known CVEs before pushing to production registries.
- Use OIDC tokens for CI/CD authentication instead of long-lived API keys or personal access tokens.
- Enable Kubernetes RBAC and Network Policies to restrict pod-to-pod communication.
- Store sensitive values in dedicated secret managers (Vault, AWS Secrets Manager) rather than environment variables.
Production Tips
- Use multi-stage Docker builds to keep production images lean and reduce attack surface.
- Tag all infrastructure resources with cost-center labels for accurate cloud billing allocation.
- Implement progressive delivery with canary or blue-green deployments to minimize blast radius.
- Set up Prometheus alerting rules for SLO breaches before they become customer-impacting incidents.
