Question 1

How to set up a reverse proxy with Caddy?

Accepted Answer

Use the `reverse_proxy` directive in the Caddyfile; it automatically handles WebSockets and load balancing. For advanced options like health checks, refer to the official documentation on reverse proxying.

Question 2

Caddy vs NGINX: which is better for production?

Accepted Answer

Caddy excels in automatic HTTPS and easier configuration with dynamic updates, while NGINX has a larger ecosystem and more fine-tuning options for high-performance scenarios. Choose Caddy for security automation or NGINX for legacy compatibility.

Question 3

Does Caddy support WebSocket connections out of the box?

Accepted Answer

Yes, Caddy supports WebSocket proxying automatically when using the reverse proxy directive, with no extra configuration needed for most use cases.

Question 4

How to force TLS certificate renewal in Caddy?

Accepted Answer

Caddy handles renewals automatically, but you can trigger a manual renewal via the admin API or by deleting the certificate storage files, after which Caddy will fetch new certificates.

Question 5

Can Caddy run in a Docker container effectively?

Accepted Answer

Yes, Caddy has official Docker images and is well-suited for containers due to its single binary nature, making it easy to deploy in orchestrated environments like Kubernetes.

Question 6

How to add custom plugins when building Caddy from source?

Accepted Answer

Use xcaddy to compile Caddy with plugins by importing them in a custom main.go file, as described in the README, which automates the process but requires Go toolchain setup.
