README

VTAdmin

VTAdmin is an experimental replacement for the vtctld2 web UI, that also allows users to manage multiple Vitess clusters from a single API and web UI.

For a more detailed writeup, refer to the original RFC.

Setup

The simplest VTAdmin deployment involves a single Vitess cluster. You can look at the local example for a minimal invocation of the vtadmin-api and vtadmin-web binaries.

Important vtadmin-api flags

Please refer to vtadmin --help for the full listing, but a few flags warrant explanation here.

  • --http-origin — this flag sets up the allowed CORS origins that vtadmin-api will serve HTTP requests for, and is required if you are (very likely) running vtadmin-api and vtadmin-web on different domains.

  • --cluster, --cluster-defaults — A DSN-style flag that allows cluster configuration options to be specified on the command-line rather than needing a config file. When both command-line cluster configs and a config file are provided, any options for a given cluster on the command-line take precedence over options for that cluster in the config file.

    For a description of the cluster configuration options, see clusters.example.yaml.

  • --http-tablet-url-tmpl — Go template string to generate a reachable http(s) address for a tablet, used to make passthrough requests to /debug/vars endpoints.

Development

Building vtadmin-api

If you are making changes to .proto files, make sure you run

source dev.env
make proto grpcvtctldclient vtadmin_web_proto_types

Then, you can run make build, and run ./bin/vtadmin with any flags you need (see the local example, and also the section on flags above).

Building and running vtadmin-web

Make sure you are using node version 12.x.

Then, you may run:

cd ./web/vtadmin
npm install

# This should be the address you passed to `./vtadmin --addr`. For example,
# "http://127.0.0.1:14200".
export REACT_APP_VTADMIN_API_ADDRESS="${vtadmin_api_addr}"
export REACT_APP_ENABLE_EXPERIMENTAL_TABLET_DEBUG_VARS="true"
npm run start

Types

type API 

type API struct {
	vtadminpb.UnimplementedVTAdminServer
	// contains filtered or unexported fields
}

API is the main entrypoint for the vtadmin server. It implements vtadminpb.VTAdminServer.

func NewAPI 

func NewAPI(clusters []*cluster.Cluster, opts Options) *API

NewAPI returns a new API, configured to service the given set of clusters, and configured with the given options.

If opts.GRPCOpts.Services is nil, NewAPI will automatically add "vtadmin.VTAdminServer" to the list of services queryable in the healthcheck service. Callers can opt-out of this behavior by explicitly setting this value to the empty slice.
