This is a diagram that I have used for this lab.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I have explained how to build a customized Docker image using Docker compose on-prem (https:\/\/tungle.ca\/?p=2<\/a>486). In this post, I will build a customized Docker image using Docker compose on AWS, then deploy WordPress via this docker container.<\/p>\n\n\n\n

+ Create a new Debian Linux instance on AWS. Then, SSH to the instance and check Debian’s host version.<\/p>\n\n\n\n

lsb_release -a<\/code><\/pre>\n\n\n\n
\"\"<\/figure>\n\n\n\n
+ Create an index.php file with your customized information.<\/p>\n\n\n\n
nano index.php<\/p>\n\n\n\n
<?php\n$yourname = \"Tung Blog!\";\n$yourstudentnumber = \"A123456789\";\n$image=\"tung.jpg\"; \/\/ this must be included and uploaded as yourpic.jpg in your docker image (Dockerfile)\n$uname=php_uname();\n$all_your_output = <<<HTML\n<html>\n<head>\n<meta charset=\"utf-8\"\/>\n<title>$yourname - $yourstudentnumber<\/title>\n<\/head>\n<body>\n<h1>$yourname - $yourstudentnumber<\/h1>\n<img src=\"\/$image\">\n<div>$uname<\/div>\n<\/body>\n<html>\nHTML;\necho $all_your_output;\n?><\/code><\/pre>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Download a free .jpg image from the Internet and change it to tung.jpg<\/p>\n\n\n\n
\"\"
Create your sample docker file.<\/figcaption><\/figure>\n\n\n\n
This tells Docker to:
– Build an image starting with the Debian 10 image.
– Label the container with your email address.
– Install Apache web service and PHP module.
– Remove the default index.html on the Apache web server document root directory.
– Copy a new index.php file and your customized image to the Apache document root directory on the docker container.
– Run the command hostname and apachectl -DFOREGROUND runs in the foreground.
– Image to describe that the container is listening on port 80.<\/p>\n\n\n\n
nano Dockerfile<\/code><\/pre>\n\n\n\n

+ Build your app with Docker Compose.<\/p>\n\n\n\n
docker build -t tung-a0123456789 .<\/code><\/pre>\n\n\n\n
\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Run your app with Docker compose.<\/p>\n\n\n\n
docker run -d -p 80:80 --cap-add sys_admin -dit tung-a0123456789<\/code><\/pre>\n\n\n\n
---\n-- -d starts docker in daemon mode, in the foreground.\n-- -d p 80:80 listening the port 80 on docker container \n-- -cap-add sys_admin: basically root access to the host.\n-- -dit: it is used for getting access to terminal inside a docker container. In this example is tung-a0123456789.<\/code><\/pre>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Check that port 80 is running on the docker container.<\/p>\n\n\n\n
netstat -antp | grep 80<\/code><\/pre>\n\n\n\n
\"\"<\/figure>\n\n\n\n
+ Check your application is running on a Docker container.<\/p>\n\n\n\n
docker container ps -a<\/code><\/pre>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Connect to the Apache website with the PHP module on the docker container (http:\/\/3.239.117.185)<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
A few commands to use for checking the docker container.<\/p>\n\n\n\n
docker ps -a\ndocker images\ndocker container ps -a\ndocker stop \"Container ID\"\ndocker rm \"Container ID\"\ndocker image rm \"ImageID\"<\/code><\/pre>\n\n\n\n
