CasaOS can host a website, but the website and the CasaOS administration interface should be treated as separate services. That was the most important advice in this short October 2023 thread: running a web server in Docker is reasonable, while exposing the CasaOS dashboard itself directly to the public Internet is a different and much riskier decision.
For a simple static site, Nginx remains a strong container choice because the official image can serve a directory of HTML, CSS, JavaScript, and images with very little configuration.
Run the Website as Its Own Container
CasaOS is a management layer for Docker and files on the underlying Linux host. A website therefore does not need to be installed into the CasaOS management service itself.
Keep the web server isolated in its own container with a dedicated content directory and only the ports it needs.
The Official Nginx Image Can Serve Static Content Directly
The current Nginx Docker image supports mapping a local website directory read-only into:
/usr/share/nginx/htmlThat model is ideal for a static personal site because the server process can read the content without modifying the source files.
Use the current official Nginx container layout for static content rather than copying an old third-party image from a 2021 tutorial.
Apache Is Also Valid, but the Choice Is Not the Security Boundary
The original question asked Apache vs Nginx. Either can host a website well. The more important decisions are how the container is updated, where the site files live, whether TLS is configured, and which network ports are exposed.
Changing from Nginx to Apache does not make a publicly exposed administration dashboard safe.
Keep the CasaOS Dashboard Private
The community responder explicitly warned against opening CasaOS itself to the web. The management interface can control files, containers, and other server functions; exposing it creates a much larger attack surface than exposing a narrowly configured website container.
Keep administration on the LAN or behind a private remote-access layer.
Use a Private Network for Administration
The source user decided to keep CasaOS at home for Jellyfin and use Tailscale for remote Nextcloud access. That is a sound separation of concerns: public website traffic can go to the web container, while administrative services stay reachable only through a private overlay network.
If the Website Must Be Public, Add TLS and a Clear Ingress Path
A public site normally needs a domain name, HTTPS certificate, and either router forwarding or an authenticated/reverse-tunnel architecture. The exact choice depends on whether you have a public IP and how much infrastructure you want to operate.
Only publish the web server ports required by the site. Do not forward unrelated CasaOS or Docker-management ports.
Patch the Web Container and Its Content Stack
A minimal static Nginx site has a relatively small attack surface, but the container still needs security updates. Dynamic sites built on PHP, WordPress, Node.js, or a database add many more moving parts and should be updated as an application stack rather than treated like plain static files.
Back Up Website Content Separately from the Container
Keep the site files in a persistent host folder or repository. If the container is recreated, the website should be recoverable without rebuilding content from inside a disposable container filesystem.
CasaOS Web Server FAQ
Can CasaOS host a website?
Yes. A Dockerized Nginx or Apache server can publish web content independently of the CasaOS UI.
Should the CasaOS dashboard itself be exposed publicly?
The source community specifically advised against that. Keep management private.
Which server is simplest for a static site?
Nginx's official Docker image provides a straightforward static-content workflow.
