 # CaddyServer with PHP-FPM

-# This is a simple Docker image to run CaddyServer with PHP-FPM.
+This is a simple Docker image to run CaddyServer with PHP-FPM.

+## Usage
+
+The following examples use images that have already been built; you can build your own images as described below.
+
+### Single Container
+
+- Configure your Caddyfile and place it in a folder on your host. Exapmle:
+
+```plaintext
+{
+    email admin@rainss.cn
+}
+example.com:80 {
+    encode gzip
+    root * /www/websites
+    php_fastcgi localhost:9000
+    file_server
+}
+```
+
+- Run the container with the following command. Example:
+
+```bash
+docker run -d -p 80:80 -p 443:443 -v /path/to/your/Caddyfile:/etc/caddy/Caddyfile -v /path/to/your/site:/www/websites --name caddyserver-php-fpm rainautos/caddyserver-php-fpm
+```
+
+### Docker Compose [Multi-container]
+
+You can use Docker Compose to run CaddyServer with PHP-FPM. For example:
+
+- Configure your Caddyfile and Using the following command to create a container. 
+
+- Caddyfile
+
+```plaintext
+{
+    email admin@rainss.cn
+}
+example.com:80 {
+    encode gzip
+    root * /www/websites
+    # notice: php-fpm is the name of the container
+    php_fastcgi php-fpm:9000
+    file_server
+}
+```
+
+#### Using Dockerfile
+
+```bash
+version: '3'
+services:
+  webservice:
+    container_name: caddy
+    image: caddy:latest
+    ports:
+      - "80:80"
+      - "443:443"
+    volumes:
+      - ${PWD}/Caddyfile:/etc/caddy/Caddyfile
+      - ${PWD}/config:/config
+      - ${PWD}/data:/data
+      - ${PWD}/websites:/www/websites
+    depends_on:
+      - php-cgi
+    restart: unless-stopped
+    networks:
+      - website
+  php-cgi:
+    container_name: php-fpm
+    build:
+      context: ./php-fpm/8.2
+      dockerfile: Dockerfile
+    volumes:
+      - ${PWD}/websites:/www/websites
+    restart: unless-stopped
+    networks:
+      - website
+networks:
+  website:
+    driver: bridge
+```
+
+#### Using Repository Image
+
+```bash
+```yaml
+version: '3'
+services:
+  webservice:
+    container_name: caddy
+    image: caddy:latest
+    ports:
+      - "80:80"
+      - "443:443"
+      - "443:443/udp"
+    volumes:
+      - /etc/localtime:/etc/localtime
+      - ${PWD}/Caddyfile:/etc/caddy/Caddyfile
+      - ${PWD}/opt/caddy/config:/config
+      - ${PWD}/opt/caddy/data:/data
+      - ${PWD}/websites:/www/websites
+    depends_on:
+      - php-cgi
+    restart: always
+    networks:
+      - website
+  php-cgi:
+    container_name: php-fpm
+    image: rainautos/php-fpm:8.1.15
+    volumes:
+      - /etc/localtime:/etc/localtime
+      - ${PWD}/websites:/www/websites
+    restart: always
+    networks:
+      - website
+networks:
+  website:
+    driver: bridge
+```
+## Build images
+
+You can find the Dockerfiles in the `supervisor` or `php-fpm` folder to build the images.
+
+### Build Caddy + PHP-FPM image
+
+```bash
+cd caddy-with-php/supervisor
+docker build -t rainautos/caddyserver-php-fpm:latest .
+```
+
+### Build PHP-FPM image
+
+```bash
+cd php-fpm/8.3
+docker build -t rainautos/php-fpm:latest .
+```

+				Your web server is working. Now make it work for you. 💪
+			</p>
+			<p>
+				Caddy is ready to serve your site over HTTPS:
+			</p>
+			<ol>
+				<li>Point your domain's A/AAAA DNS records at this machine.</li>
+				<li>Upload your site's files to <code>/var/www/html</code>.
+				<li>
+					Edit your Caddyfile at <code>/etc/caddy/Caddyfile</code>:
+					<ol>
+						<li>Replace <code>:80</code> with your domain name</li>
+						<li>Change the site root to <code>/var/www/html</code></li>
+					</ol>
+				</li>
+				<li>Reload the configuration: <code>systemctl reload caddy</code></li>
+				<li>Visit your site!</li>
+			</ol>
+			<h2>If that worked 🥳</h2>
+			<p>
+				Awesome! You won't have to look at this slanted page anymore.
+			</p>
+			<p>
+				Remember, Caddy can do a lot more than serve static files. It's also a powerful reverse proxy and
+				application platform. You can use the Caddyfile to enable any other features you need. Or you could use
+				Caddy's API to configure it programmatically.
+			</p>
+			<p>
+				Everything you need to know is either in the <a href="https://caddyserver.com/docs/">📖 Caddy
+					documentation</a> or the manual for your OS/platform. Have fun!
+			</p>
+
+			<h2>If that didn't work 😶</h2>
+			<p>
+				It's okay, you can fix it! First check the following things:
+			</p>
+			<ul>
+				<li>Service status: <code>systemctl status caddy</code></li>
+				<li>Logs: <code>journalctl --no-pager -u caddy</code></li>
+				<li>Are your site's files readable by the caddy user and group? <code>ls -la /var/www/html</code></li>
+				<li>Is the caddy home directory writeable? <code>ls -la /var/lib/caddy</code></li>
+				<li>Ensure your domain's A and/or AAAA records point to your machine's public IP address:
+					<code>dig example.com</code></li>
+				<li>Are your ports 80 and 443 externally reachable, and is Caddy able to bind to them? Check your
+					firewalls, port forwarding, and other network configuration.</li>
+			</ul>
+			<p>
+				<b class="warn">WAIT!</b> Before trying again, switch to <a
+					href="https://letsencrypt.org/docs/staging-environment/">Let's Encrypt's staging environment</a> to
+				avoid being accidentally <a href="https://letsencrypt.org/docs/rate-limits/">rate limited</a>. Once you
+				get everything else working, it's safe to switch back.
+			</p>
+			<p>
+				Depending on your DNS provider, it may take a while for the DNS records to propagate. Even when
+				everything is configured properly, automated challenges to obtain TLS certificates usually take several
+				seconds, but may take up to several minutes or hours.
+			<p>
+				If you still need help, we have a <a href="https://caddy.community/">great community</a>! First <a
+					href="https://caddy.community/search">try a search</a>, and if your question is original, go ahead
+				and ask it! Remember to pay it forward and help others too. 😁
