* Protobuf changes: - Moved `healthcheck.proto` back from viz to `proto/common` as it remains being used by the main `healthcheck.go` library (it was moved to viz by #5510). - Extracted from `viz.proto` the IP-related types and put them in `/controller/gen/common/net` to be used by both the public and the viz APIs. * Added chart templates for new viz linkerd-metrics-api pod * Spin-off viz healthcheck: - Created `viz/pkg/healthcheck/healthcheck.go` that wraps the original `pkg/healthcheck/healthcheck.go` while adding the `vizNamespace` and `vizAPIClient` fields which were removed from the core `healthcheck`. That way the core healthcheck doesn't have any dependencies on viz, and viz' healthcheck can now be used to retrieve viz api clients. - The core and viz healthcheck libs are now abstracted out via the new `healthcheck.Runner` interface. - Refactored the data plane checks so they don't rely on calling `ListPods` - The checks in `viz/cmd/check.go` have been moved to `viz/pkg/healthcheck/healthcheck.go` as well, so `check.go`'s sole responsibility is dealing with command business. This command also now retrieves its viz api client through viz' healthcheck. * Removed linkerd-controller dependency on Prometheus: - Removed the `global.prometheusUrl` config in the core values.yml. - Leave the Heartbeat's `-prometheus` flag hard-coded temporarily. TO-DO: have it automatically discover viz and pull Prometheus' endpoint (#5352). * Moved observability gRPC from linkerd-controller to viz: - Created a new gRPC server under `viz/metrics-api` moving prometheus-dependent functions out of the core gRPC server and into it (same thing for the accompaigning http server). - Did the same for the `PublicAPIClient` (now called just `Client`) interface. The `VizAPIClient` interface disappears as it's enough to just rely on the viz `ApiClient` protobuf type. - Moved the other files implementing the rest of the gRPC functions from `controller/api/public` to `viz/metrics-api` (`edge.go`, `stat_summary.go`, etc.). - Also simplified some type names to avoid stuttering. * Added linkerd-metrics-api bootstrap files. At the same time, we strip out of the public-api's `main.go` file the prometheus parameters and other no longer relevant bits. * linkerd-web updates: it requires connecting with both the public-api and the viz api, so both addresses (and the viz namespace) are now provided as parameters to the container. * CLI updates and other minor things: - Changes to command files under `cli/cmd`: - Updated `endpoints.go` according to new API interface name. - Updated `version.go`, `dashboard` and `uninstall.go` to pull the viz namespace dynamically. - Changes to command files under `viz/cmd`: - `edges.go`, `routes.go`, `stat.go` and `top.go`: point to dependencies that were moved from public-api to viz. - Other changes to have tests pass: - Added `metrics-api` to list of docker images to build in actions workflows. - In `bin/fmt` exclude protobuf generated files instead of entire directories because directories could contain both generated and non-generated code (case in point: `viz/metrics-api`). * Add retry to 'tap API service is running' check * mc check shouldn't err when viz is not available. Also properly set the log in multicluster/cmd/root.go so that it properly displays messages when --verbose is used |
