Curl Docker container compiled with HTTP/3 (h3/quic) support.

The Docker entrypoint is "curl", so simply pass any args to the docker command as you would curl. For example:

docker run -it dalgibbard/curl-http3 --connect-timeout 5 -m 5 -s -vvv --http3 https://cloudflare.com

Note that HTTP/3 occurs over UDP, so ensure your firewall is correctly setup.

At the time of writing, HTTP3 support in browsers is not enabled by default. However, multiple servers are adding support for it. For example:

• Caddy2
• NGinX
• Quiche/Cloudflare
