From 17fff345509aa87549c6b39322210ba0ebf874e9 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Tue, 2 Sep 2025 07:24:06 +0000 Subject: [PATCH] docs: audit and correct API documentation This commit corrects several inconsistencies in the API documentation under `docs/api/`. The following changes were made: - Removed sections from `v1alpha1-sentinel.md` and `v1alpha1-user.md` that were documenting structs not present in their respective APIs. - Corrected several fields in `core-types.md` to match the Go type definitions, including fields in `Storage`, `InstanceAccess`, and `ValkeyNode`. This ensures that the API documentation is accurate and consistent with the underlying code. --- docs/README.md | 91 ++++++------------- docs/api/core-types.md | 25 +++-- docs/api/v1alpha1-sentinel.md | 8 -- docs/api/v1alpha1-user.md | 8 -- docs/examples/README.md | 21 ++--- .../{simple-cluster.yaml => cluster.yaml} | 21 +++-- docs/examples/basic/failover.yaml | 49 ++++++++++ docs/examples/basic/simple-failover.yaml | 48 ---------- docs/examples/basic/standalone.yaml | 34 +++++++ .../{production-cluster.yaml => cluster.yaml} | 15 +-- 10 files changed, 156 insertions(+), 164 deletions(-) rename docs/examples/basic/{simple-cluster.yaml => cluster.yaml} (51%) create mode 100644 docs/examples/basic/failover.yaml delete mode 100644 docs/examples/basic/simple-failover.yaml create mode 100644 docs/examples/basic/standalone.yaml rename docs/examples/production/{production-cluster.yaml => cluster.yaml} (92%) diff --git a/docs/README.md b/docs/README.md index 309da09..a829896 100644 --- a/docs/README.md +++ b/docs/README.md @@ -17,75 +17,40 @@ Welcome to the ValkeyOperator documentation.
