IIEC_Docker_Project

Under IIEC-RISE 1.0 Campaign I learnt about Docker under the guidance of Vimal Daga Sir. This is my final project using Docker to set-up Nextcloud, Nextcloud is free and open-source. Nextcloud application functionally is similar to Dropbox, Office 365 or Google Drive.

1. Pre-configurations needed:

• I am using RedHat Enterprise Linux. Plus I have also installed Docker Software in it. You can use any OS and inside that OS you should have docker software installed. There might be a possibility that some Linux command might be different from other OS but I will explain what is the work of that command.

2. Setting up the required things:

• Disabling firewall:
  • Firewall might block some networking stuffs that's why I at first stopped the firewall.
  • Use systemctl stop firewalld.
• Starting the docker:
  • Use systemctl start docker to start Docker Service.

3. Downloading required images:

• Pulling MySQL Image:
  • Use docker pull mysql:5.6 to download the mysql version 5.6 image to use as a database server.
  • To know more about MySQL Image go to this page: https://hub.docker.com/_/mysql
• Pulling Nextcloud Image:
  • Use docker pull nextcloud:latest to download the Nextcloud Image in which apache server is already preconfigured.
  • To know more about Nextcloud Image go to this page: https://hub.docker.com/_/nextcloud

4. Setting up MySQL:

• Use docker run -it -e MYSQL_ROOT_PASSWORD=(any password you like) -e MYSQL_USER=(any user name) -e MYSQL_PASSWORD=(any password(recommended not to use root password) -e MYSQL_DATABASE=(any database name) --name joomladb mysql:5.6 this code and it will create a user with a database inside Your MySQL Server.
• Now if you want to see is your database created or not then you have to install MySQL cilent software in your base OS. For that use yum install mysql. Next thing check your database server ip address and use that ip while running the client software. For reference check the image below.

5. Docker-Compose:

• Before using Docker-Compose you should install the software. For reference go to this website : https://docs.docker.com/compose/install/
• You can create and edit this file using vim editor. For that use vim docker-compose.yml. I have attached the screenshots of the nextcloud os in screenshots folder.
