Sign InAWS Private CA is an AWS service that can setup and manage private CAs, as well as issue private certificates. cert-manager
is a Kubernetes add-on to automate the management and issuance of TLS certificates from various issuing sources. It will ensure certificates are valid, updated periodically and attempt to renew certificates at an appropriate time before expiry. This project acts as an addon (see https://cert-manager.io/docs/configuration/external/) to cert-manager that signs off certificate requests using AWS Private CA.
Chainguard Images are regularly-updated, minimal container images with low-to-zero CVEs.

Ensure your EKS worker nodes or Kubernetes environment have the necessary IAM policies attached for accessing AWS PCA. Policies required typically include:
acm-pca:IssueCertificate
acm-pca:GetCertificate
acm-pca:DescribeCertificateAuthority
A minimal policy to use the issuer with an authority would look like follows:
AWSPCACIssuer
to integrate with AWS PCA:Then, kubectl apply -f AWSPCAIssuer.yaml
Do kubectl describe AWSPCAIssuer
Check the Events section and you must see the message Issuer verified if everything goes correct:
Create CRD Certificate with name rsa-cert-2048 for dns name rsa-2048.example.com >> Certificate.yaml For th formats other than 2048 check the examples
Then Apply the yaml file
It should output Ready as True as shown below
Please use kubectl get events for debugging.

Chainguard Images are a collection of container images designed for security and minimalism.
Many Chainguard Images are distroless; they contain only an open-source application and its runtime dependencies. These images do not even contain a shell or package manager. Chainguard Images are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a secure software supply chain.
The main features of Chainguard Images include:
-dev
VariantsAs mentioned previously, Chainguard’s distroless Images have no shell or package manager by default. This is great for security, but sometimes you need these things, especially in builder images. For those cases, most (but not all) Chainguard Images come paired with a -dev
variant which does include a shell and package manager.
Although the -dev
image variants have similar security features as their distroless versions, such as complete SBOMs and signatures, they feature additional software that is typically not necessary in production environments. The general recommendation is to use the -dev
variants only to build the application and then copy all application artifacts into a distroless image, which will result in a final container image that has a minimal attack surface and won’t allow package installations or logins.
That being said, it’s worth noting that -dev
variants of Chainguard Images are completely fine to run in production environments. After all, the -dev
variants are still more secure than many popular container images based on fully-featured operating systems such as Debian and Ubuntu since they carry less software, follow a more frequent patch cadence, and offer attestations for what they include.
To better understand how to work with Chainguard Images, we encourage you to visit Chainguard Academy, our documentation and education platform.
