Nextcloud with WebRTC and etherpad with private and group pads

The Dockerfile used here starts with FROM ubuntu which means that by each build you run you will be starting from the latest ubuntu image available on Docker. It also means you can use this Dockerfile to build this image for diferent architectures eg. x86_64 (Mac); ARM (Raspberry Pi).

As we will be generating ssl certificates with a Certificate Authority you will need to make sure your raspberry pi is accessible to the world. For this you will need to make sure your router is forwarding ports 80 (http) and 443 (https) to your raspberry pi. For instructions on how to do this consult your router's manual.

Also, as you might not have a fixed IP you might wanna create a public Hostname with a Free Dynamic DNS. A good place for this is noip.com for which you can install the Dynamic Update Client (DUC) so that your web address continuously points to your router's external IP address. You will need 2 hostnames, 1 for Nextcloud, 1 for etherpad.

To test that this is working you can have your router forward port 22 to your raspberry pi and try to ssh to your pi over the Hostname you created at noip.com. For safety reasons you might stop this forwarding once your test comes through.

Clone the repo:

cd ~/
git clone https://github.com/jorgeboucas/docker_nextcloud_etherpad.git

Edit the variables in the Dockerfile between ##### USER GIVEN VARIABLES ##### and ##### END OF USER GIVEN VARIABLES #####. You might wanna check this blog post for help on choosing passwords.

##### USER GIVEN VARIABLES #####

# root password
ENV ROOTPASS=my_root_pass

# password for mysql
ENV myqsl_password=sqpass

# user and password for the database used by nextcloud
ENV MAINDB=nextcloud
ENV PASSWDDB=ncdbpass

# user and password for the nextcloud administrator
ENV ADMIN=nextcloud
ENV ADMINPASS=ncpass

# server info for ssl certificates
ENV SERVER_ADDRESS=nextcloud.myhostname.com
ENV SERVER_ADMIN="[email protected]"

# company info for hacking the nextcloud's landing page
ENV COMPANY_NAME=company_name
ENV COMPANY_WEBPAGE='http:\/\/www.company.com'
ENV COMPANY_SLOGAN='My Company Slogan'

# internal host ip for trusted hosts
ENV HOST_INTERNAL_IP=pi_ip_on_my_network

# user and password for the database used by etherpad
ENV ETHERPAD_MYSQL_USER=ETHERPAD_MYSQL_USER
ENV ETHERPAD_MYSQL_PASS=ETHERPAD_MYSQL_PASS

# user and password for the etherpad administrator
ENV ETHERPAD_ADMIN=ETHERPAD_ADMIN
ENV ETHERPAD_ADMIN_PASS=ETHERPAD_ADMIN_PASS

# etherpad address, ip bind,  and port
ENV ETHERPAD_WEB_ADDRESS=etherpad.myhostname.com

##### END OF USER GIVEN VARIABLES #####

Build the image and run the container:

cd ~/docker_nextcloud_etherpad
docker built -t webserver .

Run the container mapping the certificates /etc/letsencrypt, nextcloud /var/www/html, databases var/lib/mysql, and etherpad /etherpad-lite folders to your host. If you wish to create backups of your Nextcloud and etherpad instances these are the folders you need to copy/backup to a separate/3rd drive. If you ever restart your raspberry pi you can relaunch your instances by starting here:

cd ~/docker_nextcloud_etherpad
mkdir -p persistent_data/letsencrypt \
persistent_data/nextcloud \
persistent_data/db \
persistent_data/etherpad && \
docker run \
-v $(pwd)/persistent_data/letsencrypt:/etc/letsencrypt \
-v $(pwd)/persistent_data/nextcloud:/var/www/html \
-v $(pwd)/persistent_data/db:/var/lib/mysql \
-v $(pwd)/persistent_data/etherpad:/etherpad-lite \
--name cloud -d -p 80:80 -p 443:443 -p 9001:9001 webserver /bin/bash

If you wish to get a shell on the running container you can do so by

docker exec -it cloud /bin/bash

You can now access your Nextcloud instance at your defined hostname nextcloud.myhostname.com and etherpad at your defined etherpad.myhostname.com.

For login in to Nextcloud you can use the values you've set for ADMIN and ADMINPASS. You can add users to yout Nextcloud instace by using the managment console inside Nexcloud.

For WebRTC you can use the Talk app inside Nextcloud.

For login to etherpad you can use the values you've set to ETHERPAD_ADMIN and ETHERPAD_ADMIN_PASS. For private pads you can access etherpad.myhostname.com/mypads which you can administrate on etherpad.myhostname.com/mypads/?/admin.
