Creating Docker Container
In Portainer navigate to the Stacks menu and click Add stack
Name your stack and paste in the following into the web editor:
--- version: '2' services: cloudflare-ddns: image: oznu/cloudflare-ddns:latest restart: always environment: - API_KEY=xxxxxxx - ZONE=example.com - SUBDOMAIN=subdomain - PROXIED=true
You’ll want to change the coloured text with your information. The API_KEY should be the one you created earlier.
You may want to delete the subdomain line if you wanted to change the IP of your root domain only. You can then create CNAME records that point to the root of your domain for other subdomains. If you don’t want the A record to be proxied, set it to false.
After adjusting your config file, scroll down to the bottom and click “Deploy the stack”
You should see your container running, you can check the log to see what the container is doing.
