Buildah is a web-based OCI container tool that allows you to manage the wide range of images in your OCI container and helps you to build the image container from the scratch.

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.

Buildah features and specs

  • Lightweight
    Buildah is a tool focused solely on building OCI and Docker-compatible containers, which makes it less resource-intensive compared to other container building solutions that include additional components like container runtimes.
  • Daemon-less
    Unlike Docker, Buildah does not require a running daemon, meaning it can be used in environments where a daemon is not desired or feasible, enhancing security and reducing footprint.
  • Flexibility
    Buildah provides flexibility by allowing precise control over container image creation, enabling advanced scenarios like building images from scratch, adding content at various stages, and using alternative base images.
  • Security
    Running without a daemon improves security by minimizing attack surfaces and permissions needed for building images, allowing for container creation and management by unprivileged users.
  • Integration with Podman
    Buildah integrates well with Podman, allowing users to manage containers and images without requiring additional integrations, as both are part of the same toolset for comprehensive container management.

Possible disadvantages of Buildah

  • Steep Learning Curve
    Users already familiar with Docker might find Buildahโ€™s command-line interface and functionality to be different, necessitating a learning curve to effectively utilize its capabilities.
  • Less Mature Ecosystem
    Compared to Docker, Buildah has a smaller community and fewer integrations with third-party tools or cloud platforms, potentially limiting its use in complex or niche scenarios.
  • Lack of Windows Support
    As of now, Buildah primarily supports Linux platforms, which can be a limitation for developers using or targeting Windows environments.
  • Limited GUI Tools
    Buildah primarily operates through a command-line interface, with fewer graphical user interface options available, which might not appeal to users who prefer visual management tools.
  • Documentation Gaps
    Although improving, Buildahโ€™s documentation can be less comprehensive and more challenging to navigate than Docker's, potentially making troubleshooting or advanced usage more difficult.

Questions & Answers

As answered by people managing Buildah 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.

  • Podman vs. Docker: Containerization Tools Comparison
    Modern Docker releases use BuildKit, an efficient builder developed by Docker, whereas Podman uses Red Hat's Buildah. However, both solutions output OCI-compliant images, so there's no practical difference between the two for standard build workflows. - Source: dev.to / 12 months ago

  • How to Create a CI/CD Pipeline with Docker
    Lockdown your Dockerized build environments --- Because privileged mode is insecure, you should restrict your CI/CD environments to known users and projects. If this isn't feasible, then instead of using Docker, you could try using a standalone image builder like Buildah to eliminate the risk. Alternatively, configuring rootless Docker-in-Docker can mitigate some --- but not all --- of the security concerns... - Source: dev.to / about 2 years ago
  • Ko: Easy Go Containers
    In my experience, not using docker to build docker images is a good idea. E.g. buildah[0] with chroot isolation can build images in a GitLab pipeline, where docker would fail. It can still use the same Dockerfile though. If you want to get rid of your Dockerfiles anyway, nix can also build docker images[1] with all the added benefits of nix (reproducibility, efficient building and caching, automatic layering,... - Source: Hacker News / over 2 years ago
