From 2778bf988b5bad691902ef7c16ccf6f80fc48066 Mon Sep 17 00:00:00 2001 From: Brian Cook Date: Tue, 22 Jul 2025 13:58:01 -0400 Subject: [PATCH 01/28] feat: implement caching for bundle, git and cluster resolvers This commit adds caching for bundle and git resolvers to reduce chances of being rate limited by registries and git forges. - Add cache interface and in-memory implementation - Add cache configuration options to docs - Add a simple 'always on or off' option for cluster resolver - Add documentation for cache configuration Signed-off-by: Brian Cook --- config/200-role.yaml | 8 +- config/201-rolebinding.yaml | 4 +- config/resolvers/resolvers-deployment.yaml | 3 +- docs/bundle-resolver.md | 11 + docs/cluster-resolver.md | 56 + docs/git-resolver.md | 11 + docs/resolution.md | 12 + go.mod | 1 + go.sum | 2 + .../cache/annotated_resource.go | 80 + .../cache/annotated_resource_test.go | 236 +++ pkg/remoteresolution/cache/cache.go | 221 ++ pkg/remoteresolution/cache/cache_test.go | 437 ++++ pkg/remoteresolution/cache/injection/cache.go | 61 + .../resolver/bundle/resolver.go | 148 +- .../resolver/bundle/resolver_test.go | 738 +------ .../resolver/cluster/resolver.go | 122 +- .../cluster/resolver_integration_test.go | 1815 +++++++++++++++++ .../resolver/cluster/resolver_test.go | 507 ----- .../resolver/framework/cache.go | 98 + .../resolver/framework/reconciler.go | 11 + .../framework/testing/fakecontroller.go | 5 +- pkg/remoteresolution/resolver/git/resolver.go | 166 +- .../resolver/git/resolver_test.go | 9 +- .../resolver/http/resolver.go | 29 +- pkg/remoteresolution/resolver/hub/resolver.go | 13 +- pkg/resolution/resolver/bundle/bundle.go | 6 + pkg/resolution/resolver/bundle/params.go | 10 + pkg/resolution/resolver/bundle/resolver.go | 12 +- .../resolver/bundle/resolver_test.go | 33 + pkg/resolution/resolver/cluster/params.go | 2 + pkg/resolution/resolver/cluster/resolver.go | 8 + pkg/resolution/resolver/git/params.go | 2 + pkg/resolution/resolver/git/repository.go | 3 +- .../resolver/git/repository_test.go | 2 +- pkg/resolution/resolver/git/resolver.go | 140 +- pkg/resolution/resolver/http/params.go | 6 + pkg/spire/test/ca.go | 2 +- pkg/spire/test/fakebundleendpoint/server.go | 12 +- pkg/spire/test/keys.go | 10 +- test/clients.go | 3 + test/resolver_cache_integration_test.go | 234 +++ test/resolver_cache_test.go | 1406 +++++++++++++ test/resolvers_test.go | 2 +- test/tektonbundles_test.go | 3 +- .../k8s.io/code-generator/generate-groups.sh | 0 .../generate-internal-groups.sh | 0 .../knative.dev/pkg/hack/generate-knative.sh | 0 vendor/modules.txt | 2 + 49 files changed, 5325 insertions(+), 1377 deletions(-) create mode 100644 pkg/remoteresolution/cache/annotated_resource.go create mode 100644 pkg/remoteresolution/cache/annotated_resource_test.go create mode 100644 pkg/remoteresolution/cache/cache.go create mode 100644 pkg/remoteresolution/cache/cache_test.go create mode 100644 pkg/remoteresolution/cache/injection/cache.go create mode 100644 pkg/remoteresolution/resolver/cluster/resolver_integration_test.go delete mode 100644 pkg/remoteresolution/resolver/cluster/resolver_test.go create mode 100644 pkg/remoteresolution/resolver/framework/cache.go create mode 100644 test/resolver_cache_integration_test.go create mode 100644 test/resolver_cache_test.go mode change 100644 => 100755 vendor/k8s.io/code-generator/generate-groups.sh mode change 100644 => 100755 vendor/k8s.io/code-generator/generate-internal-groups.sh mode change 100644 => 100755 vendor/knative.dev/pkg/hack/generate-knative.sh diff --git a/config/200-role.yaml b/config/200-role.yaml index dcd14410597..9224b7c7a08 100644 --- a/config/200-role.yaml +++ b/config/200-role.yaml @@ -102,10 +102,10 @@ metadata: app.kubernetes.io/instance: default app.kubernetes.io/part-of: tekton-pipelines rules: -
