As You using SSR Mode of Astro , You need to deploy a Node.js Server

As Deploy System , mostly using Dockerfile , because it can combine with K8s using Load balance , auto-scaling ...etc benefit

Creating a Dockerfile

Create a file called Dockerfile in your project’s root directory. This file contains the instructions to build your site, which will differ depending on your needs. This guide can’t show all possible options but will give you starting points for SSR and static mode.

If you’re using another package manager than npm, you’ll need to adjust the commands accordingly.

SSR

This Dockerfile will build your site and serve it using Node.js on port 4321 and therefore requires the Node adapter installed in your Astro project.

# Dockerfile
FROM node:lts AS runtime
WORKDIR /app

COPY . .

RUN npm install
RUN npm run build

ENV HOST=0.0.0.0
ENV PORT=4321
EXPOSE 4321
CMD node ./dist/server/entry.mjs

SSG

• Nginx

# Dockerfile
FROM node:lts AS build
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build

FROM nginx:alpine AS runtime
COPY ./nginx/nginx.conf /etc/nginx/nginx.conf
COPY --from=build /app/dist /usr/share/nginx/html
EXPOSE 8080

# nginx.conf
worker_processes  1;

events {
  worker_connections  1024;
}

http {
  server {
    listen 8080;
    server_name   _;

    root   /usr/share/nginx/html;
    index  index.html index.htm;
    include /etc/nginx/mime.types;

    gzip on;
    gzip_min_length 1000;
    gzip_proxied expired no-cache no-store private auth;
    gzip_types text/plain text/css application/json application/javascript application/x-javascript text/xml application/xml application/xml+rss text/javascript;

    error_page 404 /404.html;
    location = /404.html {
            root /usr/share/nginx/html;
            internal;
    }

    location / {
            try_files $uri $uri/index.html =404;
    }
  }
}
