Step-by-step guide
For smooth deployment we have created 3 scripts. One must edit the script to give the correct cluster details to each script. For eg, kubeconfig file, cluster ips
and also the corrects URLs where EMCO binaries like orchestrator, clm etc are running.

- Once all pods are deployed correctly, the topology should be like below:
Manual steps for getting the m3db up and running:
As pointed out earlier, we are working on some steps which are not automated for the deployment of the stack.
In due course of time, these might as well be automated. But these are steps till then :
1. Three node cluster on which m3db needs to be deployed have to be labelled, before the m3db script is run. The commands :
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
NODES=($(kubectl get nodes --output=jsonpath={.items..metadata.name}))
kubectl label node/${NODES[0]} failure-domain.beta.kubernetes.io/region=us-west1-a
kubectl label node/${NODES[1]} failure-domain.beta.kubernetes.io/region=us-west1-b
kubectl label node/${NODES[2]} failure-domain.beta.kubernetes.io/region=us-west1-c
kubectl label node/${NODES[0]} failure-domain.beta.kubernetes.io/zone=us-west1-a --overwrite=true
kubectl label node/${NODES[1]} failure-domain.beta.kubernetes.io/zone=us-west1-b --overwrite=true
kubectl label node/${NODES[2]} failure-domain.beta.kubernetes.io/zone=us-west1-c --overwrite=true |
2. Create db namespace and bootstrap m3 db - only if required
