Restructure the installation guide and move testing and CI to its own page - #145
Restructures docs/installation.md for readability and moves the testing and CI material to a page of its own.
Installation guide
Numbers every procedure that must be followed in order, and adds connecting sentences between sections.
Package installation: clarifies the certificate and repository steps, moves the pg_createcluster fallback after the server check, splits the ColdFront packages into two install steps with a note for other PostgreSQL versions, and replaces the package tables with a hint about the patched dependencies.
Splits building from source into Building ColdFront from Source on Bare Metal and Building ColdFront from Source on Docker, each with its own prerequisites, and removes the shared Prerequisites table.
Bare metal: adds step-by-step instructions, taken from docker/Dockerfile.duckdb15-base and docker/entrypoint.sh, for building pg_duckdb and the patched DuckDB extensions, including a libcurl hint and architecture detection. The extension build, postgresql.conf settings, restart, and coldfront_duckdb role are now numbered steps.
Docker: moves the development-only pg_hba.conf warning to the top of the section, explains what the stack contains, splits the build into numbered steps (including PG_MAJOR for Compose), numbers the smoke test, and adds setup steps for your own object store.
Moves the stack and patch background into Understanding ColdFront's DuckDB Stack after the build sections, rewrites the patch descriptions, and links to it from the earlier sections.
Testing and CI
Moves the Testing & CI section to a new page, docs/testing_ci.md, under Administration in the nav and the README table of contents.
Lists the pre-commit gate's host requirements and checks, presents the full matrix as a table, rewrites the storage-backend gating and cloud CI descriptions, and moves the base-image publishing steps for maintainers to this page.
Other files
README.md and docs/configure_lakekeeper.md: updates links to the renamed headings.
mkdocs.yml: adds the new page to the nav.
Notes for review
The bare-metal pg_duckdb and DuckDB extension build steps follow the Docker recipe but have not been run on a bare-metal host. In particular, please check the libcurl /usr/local install, the compiler needed for duckdb-iceberg, and the RHEL-only package list.
This PR touches files beyond installation.md because the testing material moved to a new page and heading anchors changed.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The installation guide now covers package, bare-metal, and Docker procedures, storage verification, and DuckDB patches. A new guide documents local checks and CI workflows. README links and MkDocs navigation point to updated installation sections and the testing guide.
Changes: Installation and CI Documentation
Layer / File(s)
Summary
Package and bare-metal installation docs/installation.md, README.md, docs/configure_lakekeeper.md
The guide adds platform-specific package commands and bare-metal build and extension setup steps. Installation links target the updated source-build section.
Docker and storage workflows docs/installation.md, README.md
The guide adds Docker build and Compose instructions, container setting details, a SeaweedFS smoke test, and external object-store steps. The README link targets the Docker source-build section.
DuckDB stack and patches docs/installation.md
The guide describes the DuckDB dependency stack and patches for duckdb-iceberg, pg_duckdb, and DuckDB.
Testing, CI, and navigation docs/testing_ci.md, docs/installation.md, README.md, mkdocs.yml
The new guide documents local checks, hosted test workflows, backend requirements, cleanup, and base-image publishing. The README, installation next steps, and MkDocs navigation link to the guide.
The documentation overstates test coverage uniformity in one sentence. This is a small wording fix with no runtime impact, and the earlier installation and CI guide issues are addressed.

Review comments at @docs/installation.md:
- Line 442: Update the `docker compose up -d --build` command in the development
instructions and the smoke-test command to use the existing loopback-bound port
overrides documented in `README.md`, preserving the current build and startup
behavior.
- Line 482: Update the local-store Compose command in the installation
instructions to retain the reader’s selected PG_MAJOR override, so it does not
rebuild with the default PostgreSQL version. Preserve that override for this and
subsequent Compose commands in the documented flow.
- Line 239: Update the git apply failure handler in the patch loop to stop the
installation procedure with a nonzero status instead of only breaking the loop,
preventing the build and configuration steps from running after a failed Iceberg
patch.
- Around line 199-201: Update the installation procedure around the two git
apply commands so failure to apply either the pg_duckdb or DuckDB patch stops
execution and prevents the build and installation from proceeding. Preserve both
patch applications as prerequisites for the build.
- Line 491: Update the installation instructions around the Lakekeeper bootstrap
request to wait until `docker compose ps` reports Lakekeeper as healthy before
bootstrapping and creating the warehouse.
Review comments at @docs/testing_ci.md:
- Line 120: Update the local prerequisites documentation for the aws-vended cell
to require the AWS CLI, since local credential export depends on it. Keep the
existing session and permission requirements unchanged.
- Around line 119-120: Update the `azure-vended` and `aws-vended` entries in the
backend gates table to list every required variable and credential source,
including the Azure account and filesystem plus either its key or token file,
and the AWS role ARN, external ID, and bucket. Clarify that an incomplete gate
leaves the backend PENDING in a full matrix run, while selecting it with
`--backend` exits with an error.
- Around line 123-125: Update the CI documentation to distinguish the full
matrix job from the separate cloud job: clarify that the full matrix does not
pass COLDFRONT_AWS_DATA_ROLE_ARN or COLDFRONT_AWS_EXTERNAL_ID, so aws-vended
remains PENDING there, while cloud-aws tests aws-vended only on PostgreSQL 18;
retain the SeaweedFS-only behavior for fork PRs.

test requires cgo and, on Linux, a C compiler. Preserve the existing Go, lint,
documentation, and Docker requirements.
- Around line 128-129: Qualify the `PENDING` statement for the key-based
`azure-vended` variables: only an unset gate variable keeps the backend pending.
Clarify that when `COLDFRONT_AWS_ACCESS_KEY` is set but
`COLDFRONT_AWS_SECRET_KEY` is unset, the AWS cells still run and fail.

container IP and therefore requires an environment that can route host traffic
to Linux container IPs. Document supported Linux Docker Engine or another

- Around line 72-75: Clarify the cleanup scope in the cloud test-data section:
state that the listed cleanup mechanisms apply to vended cloud jobs, and note
that static aws, azure, and gcs cells plus key-based azure-vended runs do not
use them and may require separate cleanup.

in the testing CI documentation to clarify that the full matrix includes both
`s3` and `vended`, while the pull-request `--quick` gate runs only `s3`. Remove
claims that either backend always runs, and retain the credential-free SeaweedFS
context.
