Chainguard Containers are regularly-updated, secure-by-default container images.

Download this Container Image

For those with access, this container image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/filebrowser:latest

Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.

Compatibility Notes

Chainguard's File Browser image is comparable to the official File Browser image on Docker Hub, with the following differences:

• Like all other Chainguard Images, the File Browser image features a stripped down, minimal design
• This base image comes with apk and BusyBox and reports as being a Chainguard image.
• It has few-to-zero CVEs
• It does not run as the root user
• This image as currently built does not support the agent bundle plugins

Getting Started

File Browser can be deployed as a binary by running apk add filebrowser from the Chainguard alpine repository. It can also be deployed as a Docker container or in a Kubernetes pod.

The database config which is created by the application with BoltDB is created in the /tmp directory. It cannot be mounted to the root directory as the user has no permission to write to that location.

The following is an example Kubernetes pod manifest pod.yaml:

apiVersion: v1
kind: Pod
metadata:
  name: browser-pod
spec:
  containers:
    - name: filebrowser
      image: cgr.dev/<ORGANISATION/filebrowser>
      args:
        - "--database=/tmp/filebrowser.db"
      ports:
        - containerPort: 80
          hostPort: 8080

To test out this image, deploy a filebrowser pod in a Kubernetes cluster using this manifest:

kubectl apply -f pod.yaml

Ensure that the container is up and running and check the health status of the service

kubectl -n browser port-forward po/browser-pod 8080 &
sleep 3

curl localhost:8080/health | grep "OK" && exit 0

What are Chainguard Containers?

Chainguard Containers are minimal container images that are secure by default.

In many cases, the Chainguard Containers tagged as :latest contain only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager. Chainguard Containers are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a -dev variant.

Although the -dev container image variants have similar security features as their more minimal versions, they feature additional software that is typically not necessary in production environments. We recommend using multi-stage builds to leverage the -dev variants, copying application artifacts into a final minimal container that offers a reduced attack surface that won’t allow package installations or logins.
