* Merge main -> dev.dynamic_configuration (#1270) * Update node_exporter dependency to v1.3.1 (#1228) * Add node_exporter to depcheck * update weaveworks/common dependency * map current release flags and changed defaults * documentation * revert accidental checkin * print out flags when node_exporter test fails to assist debugging * oops, i introduced some flags from master by mistake * Introduce experimental integrations revamp (#1198) * [dev.multiple-integrations] Enable present integrations by default, deprecate enabled field (#1062) * integrations: default to enabled by default * document deprecation of enabled * pkg/integrations: support *_configs field for integrations (#1130) Creates the basic code to unmarshal integrations from a YAML field called <integration name>_configs, which is a slice of that integration. Note that this is NOT wired up to the integrations manager yet, and trying to run the agent with more than one integration of the same type will likely cause problems. * [dev.multiple-integrations] Prototype new integrations subsystem (#1142) * wip: prototype new integrations subsystem * implement Controller with basic logic for Integration and UpdateIntegration * Implement HTTPIntegration for Controller * decouple controller and subsystem * don't have controller implement integration slightly less smelly now * multiplexer integration * rely on boilerplate for multiplexing for now generics would be nice here * remove multiplex_integration.go Also a little code smelly. Instead of having integrations that run other integrations, I'm going to fall back to having only one controller. * introduce Subsystem, unexport Controller start wiring up things to Subsystem * introduce v2 agent integration to use for testing * start wiring metrics integrations * rename Options to Globals call a spade a spade * add subsystem options to globals * remove dead code * metricsutils: calculate self-scraping based on globals * complete HTTP target API * working example with agent integration * appease the linter * don't return an error when context to cancel an integration is closed * once again i am asking the linter to forgive my typos * fix bug where labels from individual targets were getting dropped at the API endpoint * pkg/config: fix broken test * finish unit tests for integrations v2 controller * metricsutil/metricshandler_integration: make job name unique Before this change, the job name would have collided when using multiple instances of the same integration. * ensure that global subsystem labels are injected into targets * integrations/v2: Infer target hostname from SD API host (#1175) * [dev.multiple-integrations] integrations/v2: allow shimming between v1 and v2 integrations. (#1179) * integrations/v2: allow shimming between v1 and v2 integrations. Shimming is done by changing how the integration registration works; a new RegisterDynamic was added that allows for creating Configs at runtime. Here be dragons; this should be removed whenever we no longer have a need for it. * fix lint * pkg/integrations/v2: use "RegisterLegacy" instead of a generic mechanism * fine, I won't add the deprecation notice if it will make the linter sad * pkg/integrations: re-align (#1181) This commit reverts 69ba2ddfa9483cc8ac6e010dd7abccd319580c80 in favor of allowing the new subsystem to handle multiple instances of integrations. This commit also removes the wal_truncate_frequency field from integrations as it is the only field from old integrations that does not have a current counterpart. * [dev.multiple-integrations] Hide integrations/v2 behind a feature flag (#1185) * feature flag wip * dynamically switch between integrations v1 and v2 default to v1. * pkg/integrations/versionselector to file in pkg/config * pkg/config: fix defaults for Integrations * pkg/config: use more generic way to unmarshal differently based on flag * add missing godoc comment * more comments * switch to deferred unmarshaling * remove unused Config field * simplify completeUnmarshal * do not perform lazy deferred unmarshaling * enable cadvisor by default * switch to using real feature flag * fix postgres_exporter * Merge main into dev.multiple-integrations (#1184) * Fix typo (#1141) * Traces: Improved pod association in PromSD processor (#1137) * Improve k8s pod association * Add tests * Changelog * typo * Add prom_sd_pod_association * Extend tests for pod associations * Docs for pod association config * Lint fixes * Move to unreleased * Add instrumentation recommendations * Remove uncessary constants * Improve tests * remote config with http(s) provider (#1143) * sample remote config code with http provider * use t.TempDir() in unit test * no need to clean up after T.TempDir() * use NewClientFromConfig and make caller responsible for calling SetDirectory * handle nil HTTPClientConfig * remove blank identifier assignment * pass basic auth command line flags for remote config * address pr nits * add expiremental flag * set loader inline * update changelog * add remote config section in docs * pr comment updates * announce patch releases for cve-2021-41090 (#1152) * Merge patch release to main (#1153) * Add secret type to sensitive values * Break out config tests to their own implementation.

The part of #1181 to remove `wal_truncate_frequency` has also been reverted. As part of this change, the enabled field is removed from the v2 common metrics configs, and v2 integrations can no longer be disabled. v2 integrations can only be disabled by removing them from the YAML. * integrations/v2: remove stale reference to ErrDisabled (fix typo too) * integrations/v2: bring in common config decoupling * [dev.multiple-integrations] Introduce autoscraper (#1195) * pkg/integrations/v2: introduce self-scraping * linting * [dev.multiple-integrations] Multiple instances of integrations (#1196) * multiple instances of integrations opt in relevant v1 integrations into supporting multiple instances * shims should check for instance key override * Document integrations-next (#1197) * document integrations-next * remove json tags since they make markdown unhappy * changelog * s/Run/RunIntegration * remove stale comment about integrations.controller purpose * create dedicated run method for instanceScraper * s/expoter/exporter/g * Document why an autoscrape.Scraper manages a set of per-instance scrapers * spell out prerequisite instead of pre-req * use go.uber.org/atomic to make the code a little easier to follow * remove started callback for running integration * use smaller interface for autoscrape Co-authored-by: Ursula Kallio <73951760+osg-grafana@users.noreply.github.com> Co-authored-by: Mario <mariorvinas@gmail.com> Co-authored-by: Robert Lankford <robert.lankford@grafana.com> Co-authored-by: Matt Durham <mattdurham@ppog.org> Co-authored-by: f11r <fiete.gruenter@rwth-aachen.de> Co-authored-by: f11r <f11r@users.noreply.github.com> Co-authored-by: Nick Pillitteri <56quarters@users.noreply.github.com> Co-authored-by: Ryan Geyer <me@ryangeyer.com> Co-authored-by: Juraci Paixão Kröhling <juraci.github@kroehling.de> Co-authored-by: Robert Lankford <rlankfo@gmail.com> * Fix panic when using 'stdout' in automatic logging (#1233) * integrations-next: fix bug where v2 integrations were not being strictly unmarshaled (#1235) * Remove jsonnet vendor folders (#1222) * remove jsonnet vendor This adds all vendor folders into .gitignore and removes cached vendor files from the repository.

This issue was introduced in #1192, but went unnoticed until #1228 implemented yaml.Unmarshaler to perform field migrations. #1240 reported the issue. This commit fixes the bug by performing a second non-strict unmarshal to ensure that all input values unmarshal successfully, with the exception of unmarshal errors unrelated to unrecognized field names. This is hacky, but it's worthwhile noting that util.UnmarshalYAMLMerged is a temporary workaround needed for the integrations-next migration, and will eventually be removed. * Update k3d example grafana/grafonnet-lib version (#1246) Signed-off-by: Paschalis Tsilias <paschalis.tsilias@grafana.com> * Create an e2e framework with support for running tests against k8s (#1234) * e2e: create an e2e framework with support for running tests against a k3d cluster * add new E2E drone job * E2E tests should pass when doing a release * sign drone.yml again * move e2e lint to different step that has golangci-lint installed * upgrade golangci-lint and go for e2e test * e2e: add gcc * E2E: install build-essential to get a working full gcc env * :( * e2e: support running from inside of docker * fix lint error * address review feedback * Operator: fix bug where /-/ready and /-/healthy always returned 404 (#1252) * operator: fix bug where /-/ready and /-/healthy always returned 404 controller-runtime must have at least one ready/healthy check for the endpoints to exist * fix lint error, use healthz.Ping * Make scraping-svc use the new `metrics:` key (#1259) Signed-off-by: Paschalis Tsilias <paschalis.tsilias@grafana.com> * update prometheus dependency (#1260) * corrected typo (#1265) * Use RELEASE_TAG to choose between `:main` and `:latest` docker tags (#1264) * Use RELEASE_TAG to choose between `:main` and `:latest` docker tags Signed-off-by: Paschalis Tsilias <paschalis.tsilias@grafana.com> * Use :main tag for images in smoke test Signed-off-by: Paschalis Tsilias <paschalis.tsilias@grafana.com> * Set IMAGE_BRANCH_TAG env var in drone and actions pipelines Signed-off-by: Paschalis Tsilias <paschalis.tsilias@grafana.com> * Remove quotes from Makefile variable Signed-off-by: Paschalis Tsilias <paschalis.tsilias@grafana.com> * Remove force_release action Signed-off-by: Paschalis Tsilias <paschalis.tsilias@grafana.com> * prepare for v0.22.0 release (#1266) * prepare for v0.22.0 release * remove E2E pipeline Co-authored-by: Robert Fratto <robert.fratto@grafana.com> Co-authored-by: Ursula Kallio <73951760+osg-grafana@users.noreply.github.com> Co-authored-by: Mario <mariorvinas@gmail.com> Co-authored-by: Robert Lankford <robert.lankford@grafana.com> Co-authored-by: f11r <fiete.gruenter@rwth-aachen.de> Co-authored-by: f11r <f11r@users.noreply.github.com> Co-authored-by: Nick Pillitteri <56quarters@users.noreply.github.com> Co-authored-by: Ryan Geyer <me@ryangeyer.com> Co-authored-by: Juraci Paixão Kröhling <juraci.github@kroehling.de> Co-authored-by: Robert Lankford <rlankfo@gmail.com> Co-authored-by: Paschalis Tsilias <tpaschalis@users.noreply.github.com> Co-authored-by: Patrick Koenig <pkoenig10@gmail.com> Co-authored-by: DataPoints <langer.markus@gmail.com> * Main merge dynamic (#1305) * Update node_exporter dependency to v1.3.1 (#1228) * Add node_exporter to depcheck * update weaveworks/common dependency * map current release flags and changed defaults * documentation * revert accidental checkin * print out flags when node_exporter test fails to assist debugging * oops, i introduced some flags from master by mistake * Introduce experimental integrations revamp (#1198) * [dev.multiple-integrations] Enable present integrations by default, deprecate enabled field (#1062) * integrations: default to enabled by default * document deprecation of enabled * pkg/integrations: support *_configs field for integrations (#1130) Creates the basic code to unmarshal integrations from a YAML field called <integration name>_configs, which is a slice of that integration.

This is hacky, but it's worthwhile noting that util.UnmarshalYAMLMerged is a temporary workaround needed for the integrations-next migration, and will eventually be removed. * Update k3d example grafana/grafonnet-lib version (#1246) Signed-off-by: Paschalis Tsilias <paschalis.tsilias@grafana.com> * Create an e2e framework with support for running tests against k8s (#1234) * e2e: create an e2e framework with support for running tests against a k3d cluster * add new E2E drone job * E2E tests should pass when doing a release * sign drone.yml again * move e2e lint to different step that has golangci-lint installed * upgrade golangci-lint and go for e2e test * e2e: add gcc * E2E: install build-essential to get a working full gcc env * :( * e2e: support running from inside of docker * fix lint error * address review feedback * Operator: fix bug where /-/ready and /-/healthy always returned 404 (#1252) * operator: fix bug where /-/ready and /-/healthy always returned 404 controller-runtime must have at least one ready/healthy check for the endpoints to exist * fix lint error, use healthz.Ping * Make scraping-svc use the new `metrics:` key (#1259) Signed-off-by: Paschalis Tsilias <paschalis.tsilias@grafana.com> * update prometheus dependency (#1260) * corrected typo (#1265) * Use RELEASE_TAG to choose between `:main` and `:latest` docker tags (#1264) * Use RELEASE_TAG to choose between `:main` and `:latest` docker tags Signed-off-by: Paschalis Tsilias <paschalis.tsilias@grafana.com> * Use :main tag for images in smoke test Signed-off-by: Paschalis Tsilias <paschalis.tsilias@grafana.com> * Set IMAGE_BRANCH_TAG env var in drone and actions pipelines Signed-off-by: Paschalis Tsilias <paschalis.tsilias@grafana.com> * Remove quotes from Makefile variable Signed-off-by: Paschalis Tsilias <paschalis.tsilias@grafana.com> * Remove force_release action Signed-off-by: Paschalis Tsilias <paschalis.tsilias@grafana.com> * prepare for v0.22.0 release (#1266) * prepare for v0.22.0 release * remove E2E pipeline * Add basic testing framework for operator (#1268) * remove dedicated go.mod for e2e/ * move e2e/k8s to pkg/util/k8s * Migrate operator tests to pkg/util/k8s * remove dedicated e2e tests * allow skipping TestCluster in pkg/util/k8s * remove e2e/ * fix bad merge * fix order of make env args for windows * actually declare referenced docker volume * introduce pkg/util/subset for asserting subset of objects * refactor operator so it's testable * define basic integration test for operator * fix lint errors * fix invalid address in operator test config * Update release-note.md (#1267) * Set scrape User-Agent header during init (#1274) Signed-off-by: Paschalis Tsilias <paschalis.tsilias@grafana.com> * Upgrade to Go 1.17 (#1278) * Upgrade to 1.17.6 in go.mod and Dockerfiles * Update CHANGELOG.md to mention the update * Update Go version in drone/actions pipelines * Update go.mod, go.sum files via * Re-sign drone.yml * Remove leading newline causing drone build to fail * Bump golangci-lint image to a version using Go 1.17 * Re-attempt to solve linter issue with new golangci-lint image * Remove suffix of exclude rules * Clean previous Go version before unpacking Go 1.17 * Also clean up previous Go versions in other steps * fix typo (#1284) * Use custom Go version in agent-operator Dockerfile (#1286) Signed-off-by: Paschalis Tsilias <paschalis.tsilias@grafana.com> * pkg/operator: refactor resource hierarchy discovery (#1271) * pkg/operator: refactor resource hierarchy discovery This commit moves common logic related to discovering the resource hierarchy to pkg/operator/hierarchy.
