Ambari APIでサービスを特定ホストにインストールする

Grafanaを例に

curl -u admin:admin -H "X-Requested-By:ambari" -i -X POST http://localhost:8080/api/v1/clusters/${_CLS}/services/AMBARI_METRICS/components/METRICS_GRAFANA
curl -u admin:admin -H "X-Requested-By:ambari" -i -X POST -d '{"host_components":[{"HostRoles":{"component_name":"METRICS_GRAFANA"}}]}' \
http://localhost:8080/api/v1/clusters/${_CLS}/hosts?Hosts/host_name=${_HOST}

インストール：
curl -u admin:admin -H "X-Requested-By:ambari" -X PUT -d '{"RequestInfo":{"context":"Install Grafana","operation_level":{"level":"HOST_COMPONENT","cluster_name":"'${_CLS}'","host_name":"'${_HOST}'","service_name":"AMBARI_METRICS"}},"Body":{"HostRoles":{"state":"INSTALLED"}}}' http://localhost:8080/api/v1/clusters/bne_c1/hosts/node1.localdomain/host_components/METRICS_GRAFANA
