What is ClickHouse?

The ClickHouse image packages the ClickHouse database server so you can run high-performance analytical workloads in containers without installing ClickHouse directly on the host. ClickHouse is purpose-built for OLAP — it excels at aggregating billions of rows in milliseconds using columnar storage, vectorized query execution, and aggressive compression. The official clickhouse/clickhouse-server image is the standard foundation for teams running real-time analytics pipelines, event data warehouses, observability backends, and product analytics platforms. It supports replication, sharding, and materialized views natively, making it a common choice in data-intensive production architectures.

What is Echo's ClickHouse image?

Echo's ClickHouse image is a hardened build of the ClickHouse server on Echo's hardened base. Echo images are designed to be a drop-in replacement: change the FROM line in your Dockerfile and CVEs go to zero without breaking your analytical workloads. Every image is tested across clouds, image use cases, and deployment targets. Echo ships every image in two variants: a distroless variant optimized for runtime use, and a default variant that includes essential build tools, package managers, and shells. For production database deployments, the distroless variant minimizes attack surface while keeping query execution, replication, and storage engine behavior fully intact; the default variant is the right choice for environments where shell access is needed for configuration management or operational tooling.

What is the difference between Echo's ClickHouse image and the public ClickHouse image?

Public ClickHouse images ship on bases that include broad OS tooling convenient for development and operations, but which contribute a substantial CVE count that security teams have to track on a long-lived, always-on database. Echo's build retains everything ClickHouse needs to serve queries, replicate data, and manage storage — while removing the packages that don't belong in a production database container. As we covered in our post on the real cost of vulnerable container images in production, persistent workloads like databases carry the highest risk from unpatched images because they run continuously and hold sensitive data. Echo commits to a 7-day SLA for critical and high severity vulnerabilities, and 10 days for medium, low, and unknown — with vulnerabilities triaged within 24 hours. Echo images are recognized by all major scanners and mirrored to all major registries, so they fit into existing pipelines without changing your registry, scanner, or runtime tooling.

FAQ

Can I replace my ClickHouse image with Echo's ClickHouse image?

Yes. Echo's ClickHouse image is a drop-in replacement. Update the FROM line in your Dockerfile or the image reference in your Helm chart and your database keeps running — the CVEs disappear, the behavior doesn't. Query execution, replication topology, materialized views, and storage engine configuration all continue to work without modification to your existing ClickHouse setup.

Is Echo's ClickHouse image FIPS-validated?

Yes. Echo's FIPS-validated images use cryptographic modules with an active FIPS 140-3 CMVP certificate, making them fit for federal use — unlike FIPS-compliant images that haven't been validated. This matters for teams running analytical databases inside FedRAMP boundaries where the data layer itself is in scope for compliance.

What is Echo's vulnerability management SLA on the ClickHouse image?

Echo commits to a 7-day SLA for critical and high severity vulnerabilities, and 10 days for medium, low, and unknown — with vulnerabilities triaged within 24 hours. Patches are mirrored automatically into your private registry so you're always running a clean version — critical for a database image that is rarely cycled in production.

Is Echo's ClickHouse image distroless?

Echo ships every image in two variants: a distroless variant optimized for runtime use, and a default variant that includes essential build tools, package managers, and shells. For production ClickHouse deployments, the distroless variant is the leaner, more secure choice; for operational environments where shell access is needed for diagnostics or configuration tooling, the default variant is the right fit.

How does Echo achieve such a drastic CVE reduction in ClickHouse?

Echo's ClickHouse image is built from source with only the absolute essentials needed to run the database workload, which significantly shrinks the attack surface. Echo also patches aggressively over time, with backports available so you can stay on the ClickHouse version that works for your analytics stack without forcing a functional change for the sake of security.

Will Echo's ClickHouse image help us achieve FedRAMP?

Yes. The hard parts of FedRAMP — managing vulnerabilities, applying fixes, and using FIPS-validated cryptography — are baked into Echo images, including STIG-hardened configuration and ConMon/POA&M-ready reporting. For teams running analytical workloads under an ATO, Echo's hardened ClickHouse image keeps the database layer in-boundary and compliant.
