virtualenv
source -p $(which python3) env/bin/activate
pip install -r requirements.txt
python main.py
Kubernetes
I am currenly running in kubernetes cluster as a cronjob checking periodically. Substitute ${IMAGE} in job.yml manually or using CI script similar to: https://github.com/KevinMidboe/cloudflare-ddns/blob/main/.drone.yml#L49-L51.
After job is created you also want to set environment variables from kubernetes secret, example .kuberenetes/secret.yml:
apiVersion: v1
kind: Secret
metadata:
name: secret-env-values
namespace: cloudflare-ddns
type: Opaque
data:
API_KEY: BASE_64_ENCODED_CLOUDFLARE_API_KEY
DDNS_ZONE: BASE64_ENCODED_CLOUDFLARE_ZONE_ID
kubectl apply -f .kuberenetes/secret.yml
