# Bitnami Secure Image for Kaniko

> Kaniko is a tool that builds and pushes container images directly in userspace. This allows securely building container images in environments like a standard Kubernetes cluster.

## TL;DR

```console
docker run -it --name kaniko bitnami/kaniko
```

## Why use Bitnami Secure Images?

Those are hardened, minimal CVE images built and maintained by Bitnami. Bitnami Secure Images are based on the cloud-optimized, security-hardened enterprise [OS Photon Linux](https://vmware.github.io/photon/). Why choose BSI images?

- Hardened secure images of popular open source software with Near-Zero Vulnerabilities
- Vulnerability Triage & Prioritization with VEX Statements, KEV and EPSS Scores
- Compliance focus with FIPS, STIG, and air-gap options, including secure bill of materials (SBOM)
- Software supply chain provenance attestation through in-toto
- First class support for the internet’s favorite Helm charts

Each image comes with valuable security metadata. You can view the metadata in [our public catalog here](https://app-catalog.vmware.com/bitnami/apps). Note: Some data is only available with [commercial subscriptions to BSI](https://bitnami.com/).

## Supported tags and respective `Dockerfile` links

Learn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags [in our documentation page](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-understand-rolling-tags-containers-index.html).

## Choosing between the _Standard_ and _Minimal_ image

This asset is available in two flavors: _Standard_ and _Minimal_; designed to address different use cases and operational needs.

### Standard images

The standard images are full-featured, production-ready containers built on top of secure base operating systems. They include:

- The complete runtime and commonly used system tools.
- A familiar Linux environment (shell, package manager, debugging utilities).
- Full compatibility with most CI/CD pipelines and existing workloads.

Recommended for:

- Development and testing environments.
- Workloads requiring package installation or debugging tools.
- Applications that depend on system utilities or shared libraries.

### Minimal images

The minimal images are optimized, distroless-style containers derived from a stripped-down base. They only ship what’s strictly necessary to run the application; no shell, package manager, or extra libraries. They provide:

- Smaller size: Faster pull and startup times.
- Reduced attack surface: Fewer components and potential vulnerabilities.
- Simpler maintenance: Fewer dependencies to patch or update.

Recommended for:

- Production environments prioritizing performance and security.
- Regulated or security-sensitive workloads
- Containers built via multi-stage builds (e.g., Golang static binaries).

## Get this image

The recommended way to get the Bitnami Kaniko Docker Image is to pull the prebuilt image from the [Docker Hub Registry](https://hub.docker.com/r/bitnami/kaniko).

```console
docker pull bitnami/kaniko:latest
```

To use a specific version, you can pull a versioned tag. You can view the [list of available versions](https://hub.docker.com/r/bitnami/kaniko/tags/) in the Docker Hub Registry.

```console
docker pull bitnami/kaniko:[TAG]
```

If you wish, you can also build the image yourself by cloning the repository, changing to the directory containing the Dockerfile and executing the `docker build` command. Remember to replace the `APP`, `VERSION` and `OPERATING-SYSTEM` path placeholders in the example command below with the correct values.

```console
git clone https://github.com/bitnami/containers.git
cd bitnami/APP/VERSION/OPERATING-SYSTEM
docker build -t bitnami/APP:latest .
```

## Configuration

The following section describes how to run commands

### Running commands

To run commands inside this container you can use `docker run`, for example to execute `kaniko --help` you can follow the example below:

```console
docker run --rm --name kaniko bitnami/kaniko:latest --help
```

Check the [official Kaniko documentation](https://github.com/chainguard-dev/kanikodocs/) for more information about how to use Kaniko.

## Notable Changes

### Starting September 23, 2025

* The `bitnami/kaniko` is now based on minimal Linux distribution instead of scratch. This change means the container now includes a shell and basic utilities, allowing you to easily debug and troubleshoot within the container.

### Starting January 16, 2024

- The `docker-compose.yaml` file has been removed, as it was solely intended for internal testing purposes.


### FIPS configuration in Bitnami Secure Images

The Bitnami Kaniko Docker image from the [Bitnami Secure Images](https://go-vmware.broadcom.com/contact-us) catalog includes extra features and settings to configure the container with FIPS capabilities. You can configure the next environment variables:

- `OPENSSL_FIPS`: whether OpenSSL runs in FIPS mode or not. `yes` (default), `no`.
- `GODEBUG`: controls Go FIPS mode. Use `fips140=only` (restricted), `fips140=on` (relaxed), or `fips140=off` (disabled).
