Fixes #5575 Now that only viz makes use of the `SelfCheck` api, merged the `healthcheck.proto` into `viz.proto`. Also removed the "checkRPC" functionality that was used for handling multiple API responses and was only used by `SelfCheck`, because the extra complexity was not granted. Revert to use the plain vanilla "check" by just concatenating error responses. ## Success Output ```bash $ bin/linkerd viz check ... linkerd-viz ----------- ... √ viz extension self-check ``` ## Failure Examples Failure when viz fails to connect to the k8s api: ```bash $ bin/linkerd viz check ... linkerd-viz ----------- ... × viz extension self-check Error calling the Kubernetes API: someerror see https://linkerd.io/checks/#l5d-api-control-api for hints Status check results are × ``` Failure when viz fails to connect to Prometheus: ```bash $ bin/linkerd viz check ... linkerd-viz ----------- ... × viz extension self-check Error calling Prometheus from the control plane: someerror see https://linkerd.io/checks/#l5d-api-control-api for hints Status check results are × ``` Failure when viz fails to connect to both the k8s api and Prometheus: ```bash $ bin/linkerd viz check ... linkerd-viz ----------- ... × viz extension self-check Error calling the Kubernetes API: someerror Error calling Prometheus from the control plane: someerror see https://linkerd.io/checks/#l5d-api-control-api for hints Status check results are × ``` |
