## Inception

A project that aims to broaden your knowledge of sys admin by using Docker.

### Steps

After a lot(and I mean a lot!) of trial and error these are the steps I took to complete the project.  

1. Set up virtual machine using latest Debian image (12.5 at time of writing)

2. Install required software - apt udpate


                             - apt install -y sudo, ufw, docker, docker-compose, make, openbox, xinit, kitty, firefox-esr

3. Do the port forwarding - ufw enable


                          - modify /etc/ssh/sshd.confit for Port 42


                          - ufw allow 443, 80 & 42


                          - shutdown the virtaul machine and add port forwarding rules in Settings


                             - SSH 42


                             - HTTP 80


                             - HTTPS 443


                         - restart the vm


                         - open a terminal and ssh into the vm with ssh [email protected] -p 42

4. Configure sudo - nano /etc/sudoers


                  - add user ALL to user priveleges


                  - add user to sudo and docker groups sudo usermod -aG docker username

5. Make directories and files for the project using the subject pdf structure

7. Modify /etc/hosts so that 127.0.0.1 points to user.42.fr

8. Create nginx container. There is lots of documentation on the internet about this.


                 - image is the Dockerfile. Needs to contain the run commands for both nginx and openssl. We use openssl to generate a self-signed certificate in TLSv1.3


                 - configuration goes in conf/nginx.conf


                 - google what is required for an openssl certificate, there is a format to follow

10. Create worpress container. In the .env file that you would have created enter login details required for wordpress (there is an example included in my github).


                - the Dockerfile needs to include the installalation of php-fpm and its dependicies


                - in the /conf folder you will need a bash script to configure wordpress (I used wp-cli for this)


                - at this point you will need the docker-compose.yml file (located at /srcs)

12. Create mariadb container - in the /conf folder you will need a bash script to configure the mysql database and store the login details in the .env file

13. Create Makefile with docker-compose commands to build, up, down, fclean etc

### Useful commands

docker-compose up -d - start container


docker-compose down - stop container


docker-compose up -d --build - build the container
  

docker ps -a - shows the list of running containers


docker-compose down --volumes - stops the container and removes the volumes


docker exec -it wordpress ps aux | grep 'php' - shows that wordpress and php have been installed


docker exec -it mariadb mysql -u user -ppwd - log into the mariadb


SHOW DATABASES - when in the mariadb will show a list of databases installed. Use this to check that a wordpress db exists.
