Cloudflare Workers - Deploy

In order to be able to deploy any Cloudflare Workers, You will need to set your Global API key from Cloudflare as an environmental variable named CLOUDFLARE_AUTH_KEY, and your Cloudflare account email as an environmental variable named CLOUDFLARE_AUTH_EMAIL. You can get your Global API key from your Cloudflare profile page. You will also need to set accountId and zoneId in serverless.yml under service.config. The first part of the path when you open Cloudflare dashboard as a logged in user is your accountId, e.g.{accountId}. And the zoneId can be found from the overview tab after selecting the desired zone from the Cloudflare dashboard.

Environmental variables are variables that live inside your terminal.

For Mac and Linux users, you can set environmental variables like this:


And for Windows (CMD) users, you can set environmental variables like this:


You’ll need to redefine your environmental variables after each time you close your terminal.

The serverless deploy command deploys your entire service via the Cloudflare Workers API. Run this command when you have made service changes (i.e., you edited serverless.yml). Use serverless deploy -f my-function when you have made code changes and you want to quickly upload your updated code to Cloudflare.

serverless deploy

This is the simplest deployment usage possible. With this command, Serverless will deploy your service to Cloudflare.
