Kustomize is an intelligent Kubernetes native configuration management software that comes with the manifestation to add, remove, or update configuration options without the need for forking.

Emisar.dev logo Emisar.dev

One governed MCP server connects any AI agent to a finite action catalog, enforced on-host with pack trust, policy gates, human approvals, and a hash-chained audit trail.

Emisar is the last MCP server youโ€™ll need to install: a Zero-Trust gateway connecting Claude, Cursor, ChatGPT, and any AI agent to your infrastructure. One server handles production access, debugging, alerts, and internal operations, with new capabilities added as packs. Agents can inspect real production state, debug what they shipped, and help resolve incidents. Safe reads run automatically; policy allows, blocks, or routes risky actions for approval. No SSH keys, VPNs, remote shells, or standing shell access โ€” and every call is recorded.

Kustomize features and specs

  • Declarative Syntax
    Kustomize provides a declarative approach to managing Kubernetes configurations, allowing users to specify desired states in YAML files rather than using scripts or imperative commands.
  • No Templating Required
    Unlike Helm, Kustomize does not use templates, reducing complexity and potential errors in rendering templates. Users can simply modify YAML files directly.
  • Layered Customization
    It allows users to apply multiple overlays or transformations to base configurations, enabling a modular and reusable approach to manage environments like dev, staging, and production.
  • Integration with kubectl
    Kustomize is integrated with kubectl since version 1.14, making it easy to use and deploy directly from the command line without needing additional tools.

Possible disadvantages of Kustomize

  • Complexity for Large Projects
    While Kustomize is great for simple transformations, managing large projects with many overlays can become complex, as dependencies and transformations have to be explicitly defined and managed.
  • Limited Features Compared to Helm
    Kustomize offers fewer features compared to Helm, such as lifecycle management and rich templating, which might be needed for more sophisticated deployment requirements.
  • Learning Curve
    Users new to Kubernetes configuration management might find Kustomize's model and functions hard to grasp initially, as it requires understanding of its specific YAML structure and practices.
  • Lack of Native Dependency Management
    Kustomize does not support native dependency management of resources, which can complicate handling interdependent resources compared to other tools like Helm.

Questions & Answers

As answered by people managing Kustomize and Emisar.dev.

How would you describe the primary audience of your product?

Emisar.dev's answer:

emisar is for SRE, DevOps, platform engineering, infrastructure, and security teams that want AI agents to inspect and operate production systems. It is especially relevant to teams managing multiple Linux hosts, clusters, databases, cloud services, or regulated environments where unrestricted shell access and incomplete audit records are unacceptable.

Which are the primary technologies used for building your product?

Emisar.dev's answer:

The hosted control plane and operator interface use Elixir, Phoenix, LiveView, PostgreSQL, and Tailwind CSS. The host runner and MCP bridge are written in Go. Action packs use YAML and JSON Schema, while production infrastructure is managed with Terraform on Google Cloud. The system communicates through MCP, OAuth 2.1, TLS, and WebSockets.

Who are some of the biggest customers of your product?

Emisar.dev's answer:

  • Blitz.gg - game analytics for billions of matches and a pretty large infrastructure.

What's the story behind your product?

Emisar.dev's answer:

Founder Andrii Dryga spent a decade working as a CTO, full-stack engineer, SRE, and DevOps engineer. He experienced the cost of running the wrong command on the wrong cluster, while also seeing AI solve operational problems in seconds. emisar grew from the need to preserve both truths: AI agents are useful, and production access must remain bounded. Its answer is to give agents a reviewed catalog of operations instead of a blank terminal.

What makes your product unique?

Emisar.dev's answer:

emisar lets AI agents work on real infrastructure without giving them a shell. Agents choose from a finite catalog of typed, versioned actions. Policy decides what runs, what requires approval, and what is denied, while an outbound-only runner verifies the action again on the host. New capabilities arrive as packs behind the same MCP integration, and every request is recorded in both a searchable audit trail and a tamper-evident host journal. [

Why should a person choose your product over its competitors?

Emisar.dev's answer:

Choose emisar when you want an agent to keep investigating and handling routine operations without handing it SSH credentials or supervising every call. Compared with raw shell access, copy-paste workflows, or one-off MCP servers, emisar provides reviewed action contracts, host-level enforcement, risk-based policy, scoped access, approvals, pack integrity checks, and a durable audit trail. It is built specifically for governed infrastructure access rather than generic automation.

  • Release on Demand
    When a change earns its way onto main, the train builds the container image one time and tags it by the commit SHA. That image is the artifact. It runs in dev immediately. And here's the part that makes promotion boring: shipping to prod doesn't rebuild anything. It re-points a config overlay (a Kustomize overlay, in practice, committed to the same repo) at the same SHA that's already running in dev. Same bytes,... - Source: dev.to / about 2 months ago
