Jaeger

Jaeger is an open-source request tracing system that can run inside of your Kubernetes cluster.

1. Append the kubectl apply command for the Jaeger resources to kubectl-apply-all.sh.

   echo kubectl apply --prune -l deploy=jaeger -f configure/jaeger --recursive >> kubectl-apply-all.sh

2. Apply your changes to Jaeger to the cluster.

   ./kubectl-apply-all.sh

3. Add the Jaeger collector agent to supported services.

   COLLECTOR_PATCH=$(yj <<EOM
   command:
   - /go/bin/agent-linux
   - --collector.host-port=jaeger-collector:14267
   image: sourcegraph/jaeger-agent@sha256:f0a6a150bb39487aadb10b04e44fdd09efb93e1a14d39b01d4f556a3b0503ea1
   name: jaeger-agent
   resources:
     limits:
       cpu: 100m
       memory: 100Mi
     requests:

       memory: 100Mi
   EOM
   )
   
   COLLECTOR_DEPLOYMENTS=(
       "github-proxy/github-proxy.Deployment.yaml"
       "query-runner/query-runner.Deployment.yaml"
       "repo-updater/repo-updater.Deployment.yaml"
       "searcher/searcher.Deployment.yaml"
       "frontend/sourcegraph-frontend.Deployment.yaml"
       "symbols/symbols.Deployment.yaml"
       "gitserver/gitserver.StatefulSet.yaml"
   )
   
   for FILE in "${COLLECTOR_DEPLOYMENTS[@]}"; do
       F="base/$FILE"
       cat $F | yj | jq ".spec.template.spec.containers += [$COLLECTOR_PATCH]" | jy -o $F
   done

4. Set useJaeger: true in your site config and follow the instructions.
