php-laravelHow can I use Docker to deploy a Laravel application written in PHP?

1. First, pull a Docker image from Docker Hub that contains the necessary components for running a Laravel application, such as an Apache web server and PHP. For example, docker pull php:7.4-apache.

2. Next, create a Dockerfile that will be used to build the container image for the Laravel application. The Dockerfile should include commands that copy the application files from the local filesystem into the image, install any necessary dependencies, and configure the web server.

3. Once the Dockerfile is created, build the container image using docker build command.

4. After the container image is built, create a container from the image using docker run command.

5. Finally, deploy the container to a server using docker push command.

6. After the container is deployed, it can be accessed by using the server's IP address or domain name.

7. To test the application, open a browser and enter the IP address or domain name of the server.

Example code block:

docker build -t laravel-app:1.0 .
