Setup - Digital Ocean
Setting up a Kubernetes Cluster with Digital Ocean (DO)
Deploy a Kubernetes cluster in DO using EKS service.
Requirements
DO account
doctl
and DO credentials configuredkubectl
LINUX/MAC is the preferred method of setup.
Windows should choose either:
Deploy a MAYANode from a Linux VPS.
Use Windows Subsystem for Linux - https://docs.microsoft.com/en-us/windows/wsl/about****
Steps
Firstly, clone and enter the cluster-launcher repository. All commands in this section are to be run inside this repo.
git clone https://gitlab.com/mayachain/devops/cluster-launcher
cd cluster-launcher
Then install the terraform CLI:
Install Terraform:
brew install terraform
DOCLI
The Digital Ocean Control tool allows you to manage your DO services.
Use the package manager homebrew to install the DO CTL.
brew install doctl
doctl auth init --context <NAME>
doctl auth switch --context <NAME>
doctl account get
You will be asked for you Personal Access Token with read/write priveleges (retrieve from API Panel from the Digital Ocean web console.)
API -> Tokens/Keys -> Create Token.
Make sure you handle your secrets securely!
Kubernetes Control Tool
You must install and configure the Kubernetes CLI tool (kubectl). **To install kubectl** , follow these instructions, or choose a package manager based on your operating system.
Use the package manager homebrew to install kubectl.
brew install kubernetes-cli
wget && jq
You also need wget and jq, follow these instructions, or choose a package manager based on your operating system.
Use the package manager homebrew to install wget and jq Note: You most likely have these installed already.
brew install wget
brew install jq
Deploy Kubernetes Cluster
Use the commands below to deploy a DOKS cluster:
make do
During the deploy, you will be asked to enter information about your cluster:

Name
DO Region -- see valid List of Regions (use lower-case)
Confirm
yes

Final success message: Apply complete! Resources: 2 added, 0 changed, 0 destroyed.
CONFIGURE
Now that you've provisioned your DOKS cluster, you need to configure kubectl. Customize the following command with your cluster name and region.
doctl kubernetes cluster kubeconfig save <use_your_cluster_name>
kubectl version
If successful, you will see:
Notice: Adding cluster credentials to kubeconfig file found in "/home/user/.kube/config"
Notice: Setting current-context to do-<region_name>-<cluster_name>
Test this configuration,
$ kubectl version
Client Version: version.Info{Major:"1", Minor:"18", GitVersion:"v1.18.6", GitCommit:"dff82dc0de47299ab66c83c626e08b245ab19037", GitTreeState:"clean", BuildDate:"2020-07-16T06:30:04Z", GoVersion:"go1.14.5", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"18", GitVersion:"v1.18.6", GitCommit:"dff82dc0de47299ab66c83c626e08b245ab19037", GitTreeState:"clean", BuildDate:"2020-07-15T16:51:04Z", GoVersion:"go1.13.9", Compiler:"gc", Platform:"linux/amd64"}
To verify, run this, and check the status is "Ready":
kubectl get nodes
NAME STATUS ROLES AGE VERSION
<cluster_name>-pool-5xhc1 READY <none> 6m v1.18.6
You are now ready to deploy a MAYANode.
