Pull the latest version of this image from the Ghost registry. Pulling requires authentication — generate a token and run docker login first (see Authentication below).
The Ghost catalog is public to browse, but pulling images requires an account. Generate a pull token below (or from your Account → Tokens page) — you'll get a ready-to-paste docker login command, then docker pull works.
The username is generated automatically (it looks like robot$<project>+<auto-id>, not the name you typed) and is included in the docker login command above. The secret is shown only once when you create the token.
All Ghost images are signed with cosign. Verifying the signature before deployment ensures the image has not been tampered with.
Install cosign via brew install cosign or download from the Sigstore releases page.
Reference this image in your Dockerfile as a base layer:
This is a vendor-built FIPS-enabled image: its cryptography runs on FIPS 140-3 validated modules configured by the upstream vendor. You can inspect the image metadata:
| Standard | FIPS 140-3 |
| Crypto module | Vendor-configured validated modules |
| Cryptography | Validated modules only |
| Use case | Government, regulated industries, compliance workloads |
Before you can use any Ghost hardened image, you must mirror the image repository from the catalog to your organization. To mirror the repository, select either Mirror to repository or View in repository > Mirror to repository, and then follow the on-screen instructions.
First follow the authentication instructions for DHI in Kubernetes.
Goldmane runs as a Kubernetes Deployment in the calico-system namespace and aggregates network flow telemetry for
Calico observability features. It is managed by the Tigera Operator when flow logging is enabled. This image is not a
standalone application and is intended to run as part of a full Calico installation.
Replace <your-namespace> with your organization's namespace, <secret name> with your Kubernetes image pull secret,
and <tag> with the image variant you want to use.
The Tigera Operator manages all Calico components. To use hardened images, configure the custom resource.
InstallationThe recommended way to deploy Calico in production is using the Tigera Operator. You can configure the operator to use Ghost hardened images for Goldmane and other Calico components via the Installation custom resource.
Goldmane requires Calico v3.31 or later and a Tigera Operator chart that includes the Goldmane CRD.
First, add the Calico Helm repository and install the Tigera Operator:
helm repo add projectcalico https://docs.tigera.io/calico/charts
helm install calico projectcalico/tigera-operator \
--namespace tigera-operator \
--create-namespace
Create an image pull secret in the tigera-operator namespace:
kubectl create secret docker-registry dhi-pull-secret \
--namespace tigera-operator \
--docker-server=docker.io \
--docker-username=<your-username> \
--docker-password=<your-token>
The Tigera Operator uses the Installation custom resource to configure Calico components, including which container images to use. To use Ghost hardened images, you must configure the Installation CR with the correct registry settings.
Important: The Installation CR image configuration applies to all Calico component images, not just Goldmane.
The operator constructs image references using this format: <registry><imagePath>/<imagePrefix><imageName>:<tag>
The Installation CR supports three fields for image configuration:
registry - Docker registry URL (must end with /). Set to registry.ghost-prod.alphabravo.io/ghost-base/ for DHI.imagePath - Path component between registry and image name. Set to dhi/ for DHI.imagePrefix - Prefix added to each image name. Set to calico- to match DHI image names.Create an Installation CR with the following configuration. Replace <your-namespace> with your organization's
namespace:
apiVersion: operator.tigera.io/v1
kind: Installation
metadata:
name: default
spec:
imagePullSecrets:
- name: dhi-pull-secret
registry: registry.ghost-prod.alphabravo.io/ghost-base/
imagePath: "dhi"
imagePrefix: "calico-"
cni:
type: Calico
calicoNetwork:
bgp: Enabled
Save this YAML to a file (e.g., installation.yaml) and apply it:
kubectl apply -f installation.yaml
Note: This configuration tells the Tigera Operator to use DHI images for all Calico components. The operator will
continuously reconcile the deployment to match the Installation CR, so it will not revert to upstream images as long as
this configuration is in place. If you only have the Calico Goldmane DHI image available, other Calico components may
fail to start with ImagePullBackOff until their DHI images are also available in your registry.
Ghost hardened images come in different variants depending on their intended use.
Runtime variants are designed to run your application in production. These images are intended to be used either
directly or as the FROM image in the final stage of a multi-stage build. These images typically:
Build-time variants typically include dev in the variant name and are intended for use in the first stage of a
multi-stage Dockerfile. These images typically:
Run as the root user
Include a shell and package manager
Are used to build or compile applications
FIPS variants include fips in the variant name and tag. They come in both runtime and build-time variants. These
variants use cryptographic modules that have been validated under FIPS 140, a U.S. government standard for secure
cryptographic operations. For example, usage of MD5 fails in FIPS variants.
To view the image variants and get more information about them, select the Tags tab for this repository, and then select a tag.
To migrate your application to a Ghost hardened image, you must update your Dockerfile. At minimum, you must update the base image in your existing Dockerfile to a Ghost hardened image. This and a few other common changes are listed in the following table of migration notes.
| Item | Migration note |
|---|---|
| Base image | Replace your base images in your Dockerfile with a Ghost hardened image. |
| Package management | Non-dev images, intended for runtime, don't contain package managers. Use package managers only in images with a dev tag. |
| Non-root user | By default, non-dev images, intended for runtime, run as the nonroot user. Ensure that necessary files and directories are accessible to the nonroot user. |
| Multi-stage build | Utilize images with a dev tag for build stages and non-dev images for runtime. For binary executables, use a static image for runtime. |
| TLS certificates | Ghost hardened images contain standard TLS certificates by default. There is no need to install TLS certificates. |
| Ports | Non-dev hardened images run as a nonroot user by default. As a result, applications in these images can't bind to privileged ports (below 1024) when running in Kubernetes or in Docker Engine versions older than 20.10. To avoid issues, configure your application to listen on port 1025 or higher inside the container. |
| Entry point | Ghost hardened images may have different entry points than images such as Docker Official Images. Inspect entry points for Ghost hardened images and update your Dockerfile if necessary. The upstream Goldmane image uses /goldmane; this image provides the same path via a symlink to /usr/local/bin/goldmane. |
| No shell | By default, non-dev images, intended for runtime, don't contain a shell. Use dev images in build stages to run shell commands and then copy artifacts to the runtime stage. |
The following steps outline the general migration process.
Find hardened images for your app.
A hardened image may have several variants. Inspect the image tags and find the image variant that meets your needs.
Update the base image in your Dockerfile.
Update the base image in your application's Dockerfile to the hardened image you found in the previous step. For
framework images, this is typically going to be an image tagged as dev because it has the tools needed to install
packages and dependencies.
For multi-stage Dockerfiles, update the runtime image in your Dockerfile.
To ensure that your final image is as minimal as possible, you should use a multi-stage build. All stages in your
Dockerfile should use a hardened image. While intermediary stages will typically use images tagged as dev, your
final runtime stage should use a non-dev image variant.
Install additional packages
Ghost hardened images contain minimal packages in order to reduce the potential attack surface. You may need to install additional packages in your Dockerfile. Inspect the image variants to identify which packages are already installed.
Only images tagged as dev typically have package managers. You should use a multi-stage Dockerfile to install the
packages. Install the packages in the build stage that uses a dev image. Then, if needed, copy any necessary
artifacts to the runtime stage that uses a non-dev image.
For Alpine-based images, you can use apk to install packages. For Debian-based images, you can use apt-get to
install packages.
The following are common issues that you may encounter during migration.
The hardened images intended for runtime don't contain a shell nor any tools for debugging. The recommended method for debugging applications built with Ghost hardened images is to use Docker Debug to attach to these containers. Docker Debug provides a shell, common debugging tools, and lets you install other tools in an ephemeral, writable layer that only exists during the debugging session.
By default image variants intended for runtime, run as the nonroot user. Ensure that necessary files and directories are accessible to the nonroot user. You may need to copy files to different directories or change permissions so your application running as the nonroot user can access them.
Non-dev hardened images run as a nonroot user by default. As a result, applications in these images can't bind to
privileged ports (below 1024) when running in Kubernetes or in Docker Engine versions older than 20.10. To avoid issues,
configure your application to listen on port 1025 or higher inside the container, even if you map it to a lower port on
the host. For example, docker run -p 80:8080 my-image will work because the port inside the container is 8080, and
docker run -p 80:81 my-image won't work because the port inside the container is 81.
By default, image variants intended for runtime don't contain a shell. Use dev images in build stages to run shell
commands and then copy any necessary artifacts into the runtime stage. In addition, use Docker Debug to debug containers
with no shell.
Ghost hardened images may have different entry points than images such as Docker Official Images. Use docker inspect
to inspect entry points for Ghost hardened images and update your Dockerfile if necessary. The Tigera Operator invokes
/health for probes; this image provides that path via a symlink to /usr/local/bin/health.
