OWnCloud-Docker-Compose-IIEC_RISE-Project

ownCloud is a self-hosted file sync and share server. It provides access to your data through a web interface, sync clients or WebDAV while providing a platform to view, sync and share across devices easily—all under your control. And to don't get any failure of data loss and making automation for files have used docker here.

With this repo you can Automatically:-

1. Pull images from DockerHub
2. Create Docker volumes for permanent use.
3. Set Up MySQl Database.
4. Set up ownCloud self-hosted file sync and share server.

Built with

• RedHat Linux RHEL8
• Docker
• owncloud
• MYSQl

Requirements/Installation

Make sure you have the latest versions of Docker and Docker Compose installed on your machine.

If Not than run the following commands:-

For Docker installation on linux[Ubuntu Distro/Similar commands for other distro as well]

sudo apt-get update
sudo apt-get remove docker docker-engine docker.io
sudo apt install docker.io

For Docker Installation on RedHAt/Centos:

• Configure yum by adding docker.repo and dvd.repo inside the /etc/yum.repos.d for local installation using https://download.docker.com/linux/centos/docker-ce.repo
• Now, run command yum install docker-ce --nobest

Start Docker:

$ sudo systemctl start docker

After Docker installation Now install Docker Compose:-

sudo curl -L https://github.com/docker/compose/releases/download/1.21.2/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

After installation of the above files:-

sudo systemctl start docker
sudo systemctl enable docker

Download the Required Images

Download The NextCloud and MySQL image from https://hub.docker.com using

docker pull owncloud:latest
docker pull mysql:5.7 

commands.

MySQL setup

Write a command

docker -i -t -e MYSQL_ROOT_PASSWORD=(your_password) -e MYSQL_USER=(username) -e MYSQL_PASSWORD=(your_password) -e MYSQL_DATABASE=       (any_database_name) --name dbos mysql:5.7

MySQL client

If you want to verify that your database folder has been created or not, install MySQL client software using yum install mysql. After installation run this command :

mysql -h 172.17.0.0/16 (your MySQL container IP) -u (username) -p

Docker-Compose

Install a docker-compose software from https://docs.docker.com/compose/install. Make a compose file using

mkdir mycompose. 

You can create/edit your docker-compose file using

vim docker-compose.yml

The file name should always be docker-compose.yml

Usage

Open a terminal and cd to the folder in which docker-compose.yml is saved and run:-

docker-compose up

Hola!, Everything is Set now the containers are now built and running. You should be able to access the WordPress installation with the configured IP in the windows browser address by http://192.168.xx.xx:8081 and for linux OS http://172.1x.x.x:8081.[Change it accordingly]

Here is an instance of my ownCloud server webssite which I built using this repo:-

Fore more reference on docker-compose

Start the containers with the up command in daemon mode (by adding -d as an argument) or by using the start command:

docker-compose start

Stopping containers

docker-compose stop

Volumes :

All our data will be permanent if we mount a volume to the folders where OwnCloud and MySQL stores data. The data will remain permanent if any of the container terminates. For that you have to create volumes first.

Depends_on :

OwnCloud uses database server. We have to specify which database container it should depend on.

Ports :

To expose our container to outside world by using PAT.

Troubleshooting the errors

Linux firewall won't allow to connect to MySQL database server and to outside world. Hence following commands should be implemented first in order to connect to server.

- selinux 0
- iptables -F
- iptables -P FORWARD ACCEPT
- firewall-cmd --zone=trusted --change-interface=docker0 --permanent (If there are any other networks for docker add them too like br-xxxxx)
- firewall-cmd --zone=trusted --add-masquerade --permanent
- firewall-cmd --add-port=3306/tcp
- firewall-cmd --reload
- systemctl restart docker
- Change your network settings to Bridge Adapter

About

This is a docker project built for need of automation and maintaining the server database in cases when local system crashes, Docker is too fast in building OS i.e. in few seconds this will help owncloud to maintain file storage safe.
