search-collector

This process runs on remotely managed clusters and collects data about the resources which exist there and how those resources relate to each other, then sends that data back to the hub cluster. In conjunction with the aggregator, provides backend functionality supporting the search features of ICP.

Config and Usage

• The application can read from a json config file, and from environment variables. If both provide a value for a specific property, the environment variable will override the file.
• The application can take any flags for glog, it will pass them straight into glog. The glog flag --logtostderr is set to true by default.

Running Locally

1. Fetch Dependencies: make deps
2. Build Binary: make build
3. Configure ~/.kube/config to point to a cluster. Or, set the KUBECONFIG environment variable to some other kubernetes config file.
4. ./output/search-collector [-c alternate config file] [any glog flags]
   • Or run with glc: ./output/search-collector [-c alternate config file] [any glog flags] 2>&1 | glc

Running on a cluster (by pushing to scratch repo)

1. Export your github username (w3id) and personal access token as GITHUB_USER and GITHUB_TOKEN
2. Fetch build harness: make init
3. Build and tag image: make build-linux docker:build docker:tag-arch
4. Export your ARTIFACTORY_USER and ARTIFACTORY_TOKEN
5. Push to scratch repo in Artifactory make docker:login docker:push-arch

Config File

A default config file for local development is provided in this repo. The file assumes the aggregator to be running at http://localhost:3010.

You can also make your own config file, defining the following values, and pass your config file to the application with -c <config file>.

{
    "AggregatorURL":<Aggregator URL, includes protocol and port but no path>,
    "ClusterName":<name of cluster>
}

Environment Variables

Instead of using a config file, you may set config properties using the following environment variables. You may also use both, the environment variables will override the values in the file.

Config Property	Environment Variable
AggregatorURL	AGGREGATOR_URL
ClusterName	CLUSTER_NAME
