By Arslan Ud Din Shafiq, Alibaba Cloud Tech Share Author. Tech Share is Alibaba Cloud's incentive program to encourage the sharing of technical knowledge and best practices within the cloud community.

Nextcloud is a suite of client-server software for creating and using file hosting services, similar to Dropbox. Nextcloud Talk is an application by Nextcloud, which allows you to organize meetings with colleagues, customers and partners with a single click.

In this tutorial, we will be installing and setting up Nextcloud Talk on an Alibaba Cloud Elastic Compute Service (ECS) with Ubuntu 16.04 installed.

Prerequisites

You must have Alibaba Cloud Elastic Compute Service (ECS) activated and verified your valid payment method. If you are a new user, you can get $300 – $1200 worth in Alibaba Cloud credits for your new account. If you don't know about how to setup your ECS instance, you can refer to this tutorial or quick-start guide. Your ECS instance must have at least 1GB RAM and 1 Core processor.
A domain name registered from Alibaba Cloud. If you have already registered a domain from Alibaba Cloud or any other host, you can update its domain nameserver records.
Domain name must be pointed to your Alibaba Cloud ECS's IP address
Access to VNC console in your Alibaba Cloud or SSH client installed in your PC
Set up your server's hostname and create user with root privileges.

Setting Up Your Server

Before proceeding with installation of any kind of package, use the following command to update your Ubuntu system. To execute this command, remember to login from non-root user with sudo privileges.

# sudo apt update && sudo apt upgrade

Software-properties-common package is required to get the supported files for installation of Docker CE. To install software-properties-common, execute the command.

# sudo apt-get install software-properties-common -y

Apt-transport-https is required for installation of Docker CE. To install apt-transport-https, execute the command.

# sudo apt-get install apt-transport-https -y

Ca-certificates is required for installation of Docker CE. To install ca-certificates, execute the command.

# sudo apt-get install ca-certificates -y

Curl is required for installation of Docker CE. To install curl execute the command.

# sudo apt-get install curl -y

Install Docker CE

To install Docker community edition, follow the steps below.

Step 1:

Add GPG key for Docker by executing command below.

# curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add –

Step 2:

Execute the following command to verify the fingerprint of GPG key.

# sudo apt-key fingerprint 0EBFCD88

Step 3:

Add the Docker repository by executing the command below.

# sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

Step 4:

Update your system by executing command below to load added repository.

# sudo apt update

Step 5:

Execute the following command to install Docker.

# sudo apt install docker-ce

Step 6:

Add your username to docker group by executing command below.

# sudo adduser aareez docker

Step 7:

Close your current shell session and start a new session. Otherwise, you won't be able to run docker and you may see permission errors.

Step 8:

Execute the following command to check either docker run correctly or not.

# docker run hello-world

Install NextCloud

To install NextCloud and Talk, follow the steps below.

Step 1:

Run the following command to download and install NextCloud on Docker.

# docker run -d -p 8080:80 nextcloud

Install Docker compose:

To keep your data consistent through upgrades and automatically handling of all containers on restart, you may use Docker compose. It is easy to launch configuration in separate database container and persistent volume. To download and install Docker compose, follow the steps below.

Step 1:

Execute the following command to download and install latest version of 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

Step 2:

Now set the permissions for file using the command below.

# sudo chmod +x /usr/local/bin/docker-compose

Step 3:

Get list of started containers using the following command.

# docker container ls --all

Stop container using port 8080. To do so, get container id, replace it with 8baab990c424 below and execute the command.

# docker stop 8baab990c424

Step 4:

Option 1 – Without SSL

If you wish to install SSL certificate, skip the steps below and go to Option 2 – With SSL, and then continue from Step 5 of this section.

Create docker-compose.yaml file, paste the following text for configurations and save the file. Before pasting text, remember to set database name, password and user.

# sudo nano docker-compose.yaml

version: '2'

volumes:
  nextcloud:
  db:

services:
  db:
    image: mariadb
    restart: always
    volumes:
      - db:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=654321Ab
      - MYSQL_PASSWORD=654321Ab
      - MYSQL_DATABASE=ncdb
      - MYSQL_USER=aareez

  app:
    image: nextcloud
    ports:
      - 8080:80
    links:
      - db
    volumes:
      - nextcloud:/var/www/html
    restart: always

Execute the following command to launch Docker Compose configuration.

# docker-compose up –d

Option 2 – With SSL

Set Up Firewalls and Ports

If you have activated firewalls, you will have to define a rule in Alibaba Cloud security group for your cloud server to add exception for port 80/tcp and 443/tcp. You can enable these ports while creating ECS instance, but in case if you have forgotten to unblock these ports, you can follow the procedure in this guide: https://www.alibabacloud.com/help/doc-detail/25471.htm

Set Up Reverse Proxy

Get list of started containers using the following command.

# docker container ls --all

Stop container using port 8080. To do so, get container id, replace it with 8baab990c424 below and execute the command.

# docker stop 8baab990c424

In this step, you will setup reverse proxy to access NextCloud Talk so that you can access it via domain name without using any port in the end of address. To do so, you will need to update docker-compose.yml file with the following text.

# sudo nano docker-compose.yml

Now add the following text in the opened file and save it.

version: '3'

services:
  db:
    image: mariadb
    command: --transaction-isolation=READ-COMMITTED --binlog-format=ROW
    restart: always
    volumes:
      - db:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=654321Ab
      - MYSQL_PASSWORD=654321Ab
      - MYSQL_DATABASE=ncdb
      - MYSQL_USER=aareez

  app:
    image: nextcloud:apache
    restart: always
    volumes:
      - nextcloud:/var/www/html
    environment:
      - VIRTUAL_HOST=softpedia.xyz
      - LETSENCRYPT_HOST=softpedia.xyz
      - LETSENCRYPT_EMAIL=arslan@gmail.com
      - MYSQL_HOST=db
      - MYSQL_PASSWORD=654321Ab
      - MYSQL_DATABASE=ncdb
      - MYSQL_USER=aareez
    depends_on:
      - db

      com.github.jrcs.letsencrypt_nginx_proxy_companion.nginx_proxy: "true"
    volumes:
      - certs:/etc/nginx/certs:ro
      - vhost.d:/etc/nginx/vhost.d
      - html:/usr/share/nginx/html
      - /var/run/docker.sock:/tmp/docker.sock:ro
    networks:
      - proxy-tier

  letsencrypt-companion:
    image: jrcs/letsencrypt-nginx-proxy-companion
    restart: always
    volumes:
      - certs:/etc/nginx/certs
      - vhost.d:/etc/nginx/vhost.d
      - html:/usr/share/nginx/html
      - /var/run/docker.sock:/var/run/docker.sock:ro
    networks:

    depends_on:
      - proxy

volumes:
  db:
  nextcloud:
  certs:
  vhost.d:
  html:

networks:
  proxy-tier:
