Add new assets

To publish a new release, project maintainers should commit new assets to the cdn/ directory and push to the main branch. The jQuery CDN (code.jquery.com) and releases site (releases.jquery.com) will both automatically rebuild.

jQuery CDN

The jQuery CDN assets are served from a static file server (Nginx), provisioned through Docker.

Prerequisites:

• Docker (see Docker CE for Linux, Docker for Mac, or Docker for Windows).
• Git.

Local development

Build the image:

Build the image, by running the following in a clone of this repo:

docker build -t codeorigin ./

Test the container in open mode:

1. Start a container, exposing port 80:

   docker run --rm -p 4000:80/tcp codeorigin
   

2. The site is now running at http://localhost:4000/jquery-3.0.0.js. To stop the container, press ctrl+c

Inspect the container:

Run it with a shell entrypoint and set interactive/tty mode by adding the parameters -i -t --entrypoint /bin/sh. Note that when inspecting the container, nginx will not be started.

docker run --rm -p 4000:80/tcp -it --entrypoint /bin/sh codeorigin

# /docker-entrypoint.d/20-envsubst-on-templates.sh 3>&1
...
# cat /etc/nginx/conf.d/default.conf
...

Inspect restricted mode:

docker run --rm -p 4000:80/tcp -e "CDN_ACCESS_KEY=$CDN_ACCESS_KEY" -it --entrypoint /bin/sh codeorigin

Debug nginx:

In cfg/default.conf, change error_log … crit to error_log … debug and then build+run as usual.

Test the container in restricted mode:

There is a restricted mode, which responds to unauthorized static file requests with a redirect instead of serving files.

1. Run export CDN_ACCESS_KEY="$(openssl rand -hex 32)"
2. Start a container, exposing port 80, and given the environment variable:

   docker run --rm -p 4000:80/tcp -e "CDN_ACCESS_KEY=$CDN_ACCESS_KEY" codeorigin
   

3. The site is now running at http://localhost:4000/jquery-3.0.0.js. To stop the container, press ctrl+c

In the restricted mode:

• Simple requests for static files redirect to code.jquery.com/*, e.g. curl -i 'http://localhost/jquery-3.0.0.js'.
• Requests with the access key will respond by serving the file: curl -i -H "x-cdn-access: $CDN_ACCESS_KEY" 'http://localhost/jquery-3.0.0.js'
• Requests with an invalid key will redirect the same as without: curl -i -H "x-cdn-access: wrong" 'http://localhost/jquery-3.0.0.js'

Production deployment

1. First, generate a CDN access key: openssl rand -hex 32.
2. At a hosting platform of your choosing, build or pull the container, and pass the CDN access key as run environment variable.
3. Finally, configure the CDN to use the container address as its origin, with special handling to augment origin pulls with a Host: code.jquery.com header, and a x-cdn-access header with the access key.

In case of emergency

If you need to deploy a standalone codeorigin site immediately, or if there are origin pull failures and you're not sure why, then deploy the container without any CDN_ACCESS_KEY environment variable. The codeorigin container then default to its unrestricted mode (no offload redirects).

WordPress build

This repository is also used to update the asset catalog at https://releases.jquery.com/, which is an auto-generated WordPress site.
