- m3operatorScript - This script has to run first as it deploys the m3operator. M3operator is a pre-requisite for the m3 cluster deployment.
Make necessary changes in the script as per the cluster details at your end. Helm charts and profile can be found at : operatorHelmChartsAndProfile
- m3dbInstallerScript - This script shall install m3db nodes. Helm charts and profile : m3dbHelmCharts
- CollectD-PrometheusScript - This script shall install collectd and prometheus. Helm charts for collectd and prometheus : collectd and prometheus
- Once all pods are deployed correctly, the topology should be like below:

Manual steps for getting the m3db up and running:
...
| Code Block |
|---|
| language | bash |

| theme | Midnight |

| title | Bootstrap M3db |

kubectl -n training port-forward svc/m3coordinator-m3db-cluster 7201
curl -vvv -X POST http://localhost:7201/api/v1/database/create -d '{
"type": "cluster",
"namespaceName": "collectd",
"retentionTime": "168h",
"numShards": "64",

}
]
}' |
3. Connecting the prometheus and m3coordinator service.
After the pods for m3db and prometheus, we need to make m3coordinator service a NodePort in case, we are not using the loadbalance.
This can be done by kubectl edit command :
| Code Block |
|---|
| language | bash |
|---|
| title | Make m3coordinator service a NodePort |
|---|
|
kubectl edit svc/m3coordinator-m3-clusterEdit type to be nodePort : 32701 |
