Chainguard Container for prometheus-elasticsearch-exporter-bitnami-fips

Minimalist Wolfi-based Prometheus Elasticsearch Exporter image for exporting various metrics about Elasticsearch.

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/prometheus-elasticsearch-exporter-bitnami-fips:latest

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

Compatibility Notes

The Chainguard prometheus-elasticsearch-exporter-bitnami-fips Image is meant to serve as a drop-in replacement for bitnami/elasticsearch-exporter image from Docker Hub. Like most other Chainguard Images, this image has few-to-zero CVEs and does not run as the root user.

Please note that the elasticsearch_exporter binary that constitute this image is not configurable with TLS, and only serves metrics on a plain HTTP port. Running this image in a FIPS environment will require controlling access to the metrics service or pod using a TLS enabled proxy in front of it. The binary supports connecting to remote TLS enabled Elasticsearch instances in FIPS mode. Refer to the Configuration section of the program's readme for the relevant flags.

Getting Started

The prometheus-elasticsearch-exporter-bitnami-fips metrics exporter is designed to work with Elasticsearch Bitnami images that are deployed using Helm charts. The following example demonstrates how to configure the Bitnami Elasticsearch Helm chart with the metrics exporter:

cat <<EOF > values.yaml
global:
  security:
    allowInsecureImages: true

master:
  replicaCount: 1
  readinessProbe:
    initialDelaySeconds: 15

data:
  replicaCount: 1
  readinessProbe:
    initialDelaySeconds: 15

coordinating:
  replicaCount: 1
  readinessProbe:
    initialDelaySeconds: 15

ingest:
  enabled: false

metrics:
  enabled: true
  image:
    registry: cgr.dev
    repository: ORGANIZATION/prometheus-elasticsearch-exporter-bitnami-fips
    tag: latest
    pullSecrets:
     - name: cgrcred
  extraVolumes:
    - name: elasticsearch-certs
      secret:
        secretName: prometheus-elasticsearch-exporter-master-crt
  extraVolumeMounts:
    - name: elasticsearch-certs
      mountPath: /etc/ssl/prometheus-elasticsearch-exporter-certs
      readOnly: true
  args:
  - --es.uri=https://prometheus-elasticsearch-exporter:9200
  - --es.all
  - --es.ca=/etc/ssl/prometheus-elasticsearch-exporter-certs/ca.crt
  - --es.client-cert=/etc/ssl/prometheus-elasticsearch-exporter-certs/tls.crt
  - --es.client-private-key=/etc/ssl/prometheus-elasticsearch-exporter-certs/tls.key
  - --no-es.ssl-skip-verify
  - --web.listen-address=:9114

security:
  enabled: true
  elasticPassword: changeit
  tls:
    autoGenerated: true
EOF

And then install the Bitnami Elasticsearch chart:

$ helm upgrade --install prometheus-elasticsearch-exporter oci://registry-1.docker.io/bitnamicharts/elasticsearch -f values.yaml

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.
