Ghost-application

1. Latest version of docker-compose installed

To launch the application, follow below steps:

1. Clone/Download the code in your local
2. run "docker-compose up"

Application involves 3 services:

1. Backend : MySQL
2. Application : Ghost-app
3. Webserver : NGINX

• Firstly, MySQL container starts. Make sure to use the username and password to login to mysql DB as mentioned in compose file. To make the data persistent we will use a named Docker volume called "mysql-volume". The data from /var/lib/mysql (path inside our MySQL container) will be mounted in the volume.

• Ghost service starts after mysql only. Ghost will use this DB to connect with the MySQL container. There is a script file under ghost folder "wait-for-it.sh". Ghost will use this script to check if the MySQL service inside the MySQL container is already running, before it will connect. ghost folder contains a Dockerfile and scriptfile "wait-for-it.sh". Ghost service use this Dockerfile to build the ghost image. To make the data persistent we will use a named Docker volume called "ghost-volume". The data from /var/lib/ghost/content (path inside our Ghost container) will be mounted in the volume.

• Lastly, We are using NGINX webserver. We are using cutom NGINX configuration "default.conf" which are stored in nginx folder with a Dockerfile to use the custom configuration while building NGINX image. Custom NGINX configuration includes foloowing:

  1. Enable HTTPS and redirect HTTP to HTTPS

  2. Creation of self-signed certificates with the help of following command : openssl req -x509 -nodes -days 365 -newkey rsa:4096 -keyout nginx-selfsigned.key -out nginx-selfsigned.crt

  3. Generate a DH key and enable dhparam with the help of following command : openssl dhparam -out dhparam.pem 2048

  4. Enable HSTS

All the newly created certificates and keys are stored in "/etc/selfsign" for this project and we are using mount volume from the same path in docker-compose.yml

To access the NGINX container from outside world, Make sure to map host port (80/443) with container port (80/443)

To run the app Use : docker-compose up Check if all the 3 containers are running, use docker ps

If all the containers are runnig, Browse the application on browser using http://HOSTIP>
