Tech Stack

• Docker
• Terraform
• Ansible
• DigitalOcean Kubernetes

Prerequisites

• terraform installed
• kubectl installed
• ansible installed

All the above tools can be installed via brew on macOS.

Steps

1. Clone the repository
2. Create a DigitalOcean API token.
3. Create a DigitalOcean Kubernetes cluster using terraform init and terraform apply. Provide the DigitalOcean API token when prompted.
4. Notice the cluster configuration file. Create / edit new configuration file to the default location.

nano $HOME/.kube/config

5. Install tools using Ansible by running the following command:

ansible-playbook -e kubeconfig=../terraform/kubeconfig.yaml cluster-setup.yml

6. Provide Cloudfare API token.

kubectl create secret generic cloudflare-api-token-secret --from-literal=api-token='YOUR_CLOUDFLARE_API_TOKEN'

7. Create Github Container Registry secret. YOUR_GITHUB_PERSONAL_ACCESS is ghp token with repo, worklow and write permissions.

kubectl create secret docker-registry k8s-ghcr \
--docker-server=https://ghcr.io \
--docker-username=<YOUR_GITHUB_USERNAME> \
--docker-password=<YOUR_GITHUB_PERSONAL_ACCESS-TOKEN> \
--docker-email=<YOUR_GITHUB_EMAIL>

8. Creat env for the application.

kubectl create secret generic evs-be-secret --from-env-file=.env
