Docker

Introduction

Docker is a set of platform as a service products that use OS-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files but they can communicate with each other through well-defined channels.

https://www.docker.com - Official Web Site.

https://hub.docker.com - Official Repository of Container Images.

It was originally developed for programmers to test their software but has now become a fully fledged answer to running servers in mission critical situations.

Each container has a mini operating system plus the software needed to run the program you want, and no more.

All of the 'hard work' for a piece of software has been 'done for you' and the end result is starting a program with one command line.

For example, the WordPress image contains the LAP part of LAMP (Linux + Apache + PHP) all configured and running.

Installation

Engine

This will remove the old version of 'Docker' and install the new version 'Docker CE'...

sudo apt-get remove docker docker-engine docker.io
sudo apt-get -y install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo apt-key fingerprint 0EBFCD88
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt-get -y install docker-ce
sudo docker run hello-world

https://docs.docker.com/install/linux/docker-ce/ubuntu/#install-docker-ce-1

Compose

curl -I -s "https://github.com/docker/compose/releases/latest" | grep 'location:' | sed 's/^.*[/]//'

Check the latest version of 'Docker Compose' and edit the following command...

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
/usr/local/bin/docker-compose --version

Volumes

Multiple Containers

Use volumes which are bind mounted from the host filesystem between multiple containers.

First, create the volume bind mounted to the folder...

docker volume create --driver local --opt type=none --opt device=/path/to/folder --opt o=bind volume_name

Then, use it in your docker compose file...

services:
  ftp.domain.uk-nginx:
    image: nginx
    container_name: ftp.domain.uk-nginx
    expose:
      - "80"
    volumes:
      - ./data/etc/nginx:/etc/nginx
      - ftp.domain.uk:/usr/share/nginx:ro
    environment:
      - VIRTUAL_HOST=ftp.domain.uk
networks:
  default:
    external:
      name: nginx-proxy-manager
volumes:
  ftp.domain.uk:
    external: true

Using volumes in Docker Compose

Networks

Create your network...

docker network create existing-network

Use it in your docker-compose.yml file...

services:
  service_name:
    image: image_name:latest
    restart: always
    networks:
      - existing-network
networks:
  existing-network:
    external: true

https://poopcode.com/join-to-an-existing-network-from-a-docker-container-in-docker-compose/

Docker Compose

Restart Policy

The "no" option has quotes around it...

restart: "no"
restart: always
restart: on-failure
restart: unless-stopped

Management

Cleaning Space

Over the last month, a whopping 14Gb of space was being used by /var/lib/docker/overlay2/ and needed a way to safely remove unused data.

Check your space usage...

du -mcsh /var/lib/docker/overlay2
14G     /var/lib/docker/overlay2

Check what Docker thinks is being used...

docker system df
TYPE            TOTAL     ACTIVE    SIZE      RECLAIMABLE
Images          36        15        8.368GB   4.491GB (53%)
Containers      17        15        70.74MB   286B (0%)
Local Volumes   4         2         0B        0B
Build Cache     0         0         0B        0B

Clean...

docker system prune
docker image prune --all

Check again...

du -mcsh /var/lib/docker/overlay2
9.4G    /var/lib/docker/overlay2

docker system df
TYPE            TOTAL     ACTIVE    SIZE      RECLAIMABLE
Images          13        13        4.144GB   144MB (3%)
Containers      15        15        70.74MB   0B (0%)
Local Volumes   4         2         0B        0B
Build Cache     0         0         0B        0B

...job done.

Updates

Tracking

Watchtower

A process for automating Docker container base image updates.

With watchtower you can update the running version of your containerized app simply by pushing a new image to the Docker Hub or your own image registry. Watchtower will pull down your new image, gracefully shut down your existing container and restart it with the same options that were used when it was deployed initially.

First Time Run Once Check Only

This will run and output if there are any updates them stop and remove itself...

docker run --name watchtower -v /var/run/docker.sock:/var/run/docker.sock containrrr/watchtower --run-once --debug --monitor-only --rm

Automated Scheduled Run Daily

This will start the container and schedule a check at 4am every day...

~/watchtower/docker-compose.yml

version: "3"
services:
  watchtower:
    image: containrrr/watchtower
    container_name: watchtower
    restart: always
    volumes:

Updating

You can either ask Watchtower to update the containers automatically for you, or do it manually.

Manually updating when using docker-compose...

cd /path/to/docker/stack/
docker-compose stop
docker-compose pull
docker-compose start

Bitwarden

~/bitwardenrs/docker-compose.yml

version: "2"
services:
  bitwardenrs:
    image: bitwardenrs/server:latest
    container_name: bitwardenrs
    volumes:
      - ./data:/data/
    ports:
      - 8100:80
    restart: unless-stopped
    environment:
      - TZ=Europe/London
      #- SIGNUPS_ALLOWED=false
      #- INVITATIONS_ALLOWED=false
      #- WEB_VAULT_ENABLED=false
networks:
  default:
    external:
      name: nginx-proxy-manager

Uncomment the extra security # lines after you have signed up, imported your old vault and set up your phone app and browsers, etc.

docker-compose down
docker-compose up -d

Check that the Bitwarden container environment has all the variables...

docker exec -it bitwardenrs env | sort

HOME=/root
HOSTNAME=e5f327deb4dd
INVITATIONS_ALLOWED=false
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
ROCKET_ENV=staging
ROCKET_PORT=80
ROCKET_WORKERS=10
SIGNUPS_ALLOWED=false
TERM=xterm
TZ=Europe/London
WEB_VAULT_ENABLED=false

... and then refresh your web vault page to see it see "404: Not Found" :-)

InfluxDB

You can have InfluxDB on its own but there is little point without something to view the stats so you might as well include InfluxDB in the Grafana stack and start both at the same time... see below :-)

Grafana

Here is a stack in docker-compose which starts both containers in their own network so they can talk to one another. I have exposed ports for InfluxDB and Grafana to the host so I can use them from the internet.

Obviously, put your firewall in place and change the passwords below!

~/grafana/docker-compose.yml

version: "3"
services:
  grafana:
    image: grafana/grafana
    container_name: grafana
    restart: always
    networks:
      - grafana-influxdb-network
    ports:
      - 3000:3000
    volumes:
      - ./data/grafana:/var/lib/grafana
    environment:
      - INFLUXDB_URL=http://influxdb:8086
    depends_on:
      - influxdb
  influxdb:
    image: influxdb:1.8.4
    container_name: influxdb
    restart: always
    networks:
      - grafana-influxdb-network
    ports:
      - 8086:8086
    volumes:
      - ./data/influxdb:/var/lib/influxdb
    environment:
      - INFLUXDB_DB=grafana
      - INFLUXDB_USER=grafana
      - INFLUXDB_USER_PASSWORD=password
      - INFLUXDB_ADMIN_ENABLED=true
      - INFLUXDB_ADMIN_USER=admin 
      - INFLUXDB_ADMIN_PASSWORD=password 
      - INFLUXDB_URL=http://influxdb:8086
networks:
  grafana-influxdb-network:
    external: true

After this, change your Telegraf configuration to point to the new host and change the database it uses to 'grafana'.

NGiNX Proxy Manager

Provide users with an easy way to accomplish reverse proxying hosts with SSL termination that is so easy a monkey could do it.

Set up your host
Add a proxy to point to the host (in Docker this will be the 'name' and the port)
Go to http://yourhost

https://nginxproxymanager.com

https://github.com/jc21/nginx-proxy-manager

Create the Docker network with a chosen subnet (used later for fixing container IP addresses)...

sudo -i
docker network create --subnet=172.20.0.0/16 nginx-proxy-manager

/root/stacks/nginx-proxy-manager/docker-compose.yml

version: '3'
services:
  db:

      MYSQL_DATABASE: 'npm'
      MYSQL_USER: 'npm'
      MYSQL_PASSWORD: 'npm'
    volumes:
      - ./data/mysql:/var/lib/mysql

      nginx-proxy-manager:
        ipv4_address: 172.20.0.3
    ports:
      - '80:80'
      - '81:81'
      - '443:443'
    environment:
      TZ: "Europe/London"
      DB_MYSQL_HOST: "db"
      DB_MYSQL_PORT: 3306
      DB_MYSQL_USER: "npm"
      DB_MYSQL_PASSWORD: "npm"
      DB_MYSQL_NAME: "npm"
    volumes:
      - ./data:/data
      - ./data/letsencrypt:/etc/letsencrypt
    depends_on:
      - db
networks:
  nginx-proxy-manager:
    external: true

Reset Password

docker exec -it nginx-proxy-manager_db sh
mysql -u root -p npm
select * from user;
delete from user where id=1;
quit;
exit

Custom SSL Certificate

You can add a custom SSL certificate to NPM by saving the 3 parts of the SSL from Let's Encrypt...

privkey.pem
cert.pem
chain.pem

...and then uploading them to NPM.

Updating

docker-compose pull
docker-compose up -d

Quick Container

Run and delete everything afterwards (press CTRL+C to stop it)...

docker run --rm --name test.domain.org-nginx -e VIRTUAL_HOST=test.domain.org nginx

Run and detach and use a host folder to store the web pages and keep the container afterwards...

docker run --name test.domain.org-nginx -e VIRTUAL_HOST=test.domain.org -v /some/content:/usr/share/nginx/html:ro -d nginx

Run and detach and connect to a specific network (like nginx-proxy-manager) and use a host folder to store the web pages and keep the container afterwards...

 docker run --name test.domain.org-nginx --network nginx-proxy-manager -e VIRTUAL_HOST=test.domain.org -v /some/content:/usr/share/nginx/html:ro -d nginx

Check the logs and always show them (like tail -f)...

Proxy

This is very cool and allows you to run multiple web sites on-the-fly.

The container connects to the system docker socket and watches for new containers using the VIRTUAL_HOST environment variable.

Start this, then add another container using the VIRTUAL_HOST variable and the proxy container will change its config file and reload nginx to serve the web site... automatically.

Incredible.

~/nginx-proxy/docker-compose.yml

version: "3"
services:
  nginx-proxy:
    image: jwilder/nginx-proxy
    container_name: nginx-proxy
    ports:
      - "80:80"
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro
networks:
  default:
    external:
      name: nginx-proxy

Normal

When using the nginx-proxy container above, you can just spin up a virtual web site using the standard 'nginx' docker image and link it to the 'nginx-proxy' network...

docker run -d --name nginx-website1.uk --expose 80 --net nginx-proxy -e VIRTUAL_HOST=website1.uk nginx

To use the host filesystem to store the web page files...

docker run -d --name nginx-website1.uk --expose 80 --net nginx-proxy -v /var/www/website1.uk/html:/usr/share/nginx/html:ro -e VIRTUAL_HOST=website1.uk nginx

In Docker Compose, it will look like this...

~/nginx/docker-compose.yml

version: "3"
services:
  nginx-website1.uk:
    image: nginx
    container_name: nginx-website1.uk
    expose:
      - "80"
    volumes:
      - /var/www/website1.uk/html:/usr/share/nginx/html:ro
    environment:
      - VIRTUAL_HOST=website1.uk
networks:

PHP File Uploads Fix

Create a new PHP configuration file, and name it docker-uploads.ini. Add the following configuration then save the changes.

# Allow HTTP file uploads
file_uploads = On

# Maximum size of an uploaded file
upload_max_filesize = 64M

# Maximum size of form post data
post_max_size = 64M

Update the docker-compose.yml to bind the docker-uploads.ini to the wordpress container and then restart the WordPress container.

volumes:
  - ./data/config/docker-uploads.ini:/usr/local/etc/php/conf.d/docker-uploads.ini

WordPress Clone

Create your A record in DNS using AWS Route 53 CLI...

cli53 rrcreate domain.co.uk 'staging 300 A 123.456.78.910'

Create your docker folder for the cloned staging test web site...

mkdir -p ~/docker/stacks/staging.domain.co.uk/data/{db,html}

Edit your docker compose file, with 2 containers, making sure you use the same network as your Nginx Proxy Manager...

Start containers with correct settings and credentials for existing live web site (so that the docker startup script sets up the MySQL permissions)...

docker-compose up -d

Check the logs to make sure all is well...

docker logs staging.domain.co.uk-wordpress
docker logs staging.domain.co.uk-wordpress_db

Copy the WordPress files to the host folder and correct ownership...

rsync -av /path/to/backup_unzipped_wordpress/ ~/docker/stacks/staging.domain.co.uk/html/
chown -R www-data:www-data ~/docker/stacks/staging.domain.co.uk/html/

Copy the sql file in to the running mysql container...

docker cp /path/to/backup_unzipped_wordpress/db_name.sql mysql_container_name:/tmp/

Log in to the database container...

docker exec -it mysql_container_name bash

Check and if necessary, change the timezone...

date
mv /etc/localtime /etc/localtime.backup
ln -s /usr/share/zoneinfo/Europe/London /etc/localtime
date

Delete and create the database...

mysql -u root -p -e "DROP DATABASE db_name; CREATE DATABASE db_name;"

Import the database from the sql file, check and exit out of the container...

mysql -u root -p mysql_db_name < /tmp/db_name.sql
mysql -u root -p -e "use db_name; show tables;"
rm /tmp/db_name.sql
exit

Edit the wp-config.php on your host server to match new DB_HOST and also add extra variables to be sure...

nano /path/to/docker/folder/html/wp-config.php
define( 'WP_HOME', 'http://staging.domain.co.uk' );
define( 'WP_SITEURL', 'http://staging.domain.co.uk' );

Install WordPress CLI in the running container...

docker exec -it wordpress_container_name bash

Search and replace the original site url...

./wp --allow-root search-replace 'http://www.domain.co.uk/' 'http://staging.domain.co.uk/' --dry-run
./wp --allow-root search-replace 'http://www.domain.co.uk/' 'http://staging.domain.co.uk/'

Start your web browser and go to the test staging web site!

WordPress CLI

In your stack, set up the usual two DB + WordPress containers, then add a third services section for wp-cli...

version: "3"
services:
  www.domain.uk-wordpress_db:
    image: mysql:5.7
    container_name: www.domain.uk-wordpress_db
    volumes:
      - ./data/db:/var/lib/mysql
    restart: always
    environment:
      - MYSQL_ROOT_PASSWORD=password
      - MYSQL_DATABASE=wordpress
      - MYSQL_USER=wordpress
      - MYSQL_PASSWORD=password
  www.domain.uk-wordpress:
    depends_on:
      - www.domain.uk-wordpress_db
    image: wordpress:latest
    container_name: www.domain.uk-wordpress
    volumes:
      - ./data/html:/var/www/html
    expose:
      - 80
    restart: always
    environment:
      - VIRTUAL_HOST=www.domain.uk
      - WORDPRESS_DB_HOST=www.domain.uk-wordpress_db:3306
      - WORDPRESS_DB_NAME=wordpress
      - WORDPRESS_DB_USER=wordpress
      - WORDPRESS_DB_PASSWORD=password
  www.domain.uk-wordpress-cli:
    image: wordpress:cli
    container_name: www.domain.uk-wordpress-cli
    volumes:
      - ./data/html:/var/www/html
    environment:
      - WP_CLI_CACHE_DIR=/tmp/
      - VIRTUAL_HOST=www.domain.uk
      - WORDPRESS_DB_HOST=www.domain.uk-wordpress_db:3306
      - WORDPRESS_DB_NAME=wordpress
      - WORDPRESS_DB_USER=wordpress
      - WORDPRESS_DB_PASSWORD=password
    working_dir: /var/www/html
    user: "33:33"
networks:
  default:
    external:
      name: nginx-proxy-manager

...then start it all up.

docker-compose up -d

Then, run your wp-cli commands (e.g. wp user list) on the end of a docker run command...

docker-compose run --rm www.domain.uk-wordpress-cli wp --info
docker-compose run --rm www.domain.uk-wordpress-cli wp cli version
docker-compose run --rm www.domain.uk-wordpress-cli wp user list
docker-compose run --rm www.domain.uk-wordpress-cli wp help theme
docker-compose run --rm www.domain.uk-wordpress-cli wp theme delete --all

Email Server (mailu)

Mailu is a simple yet full-featured mail server as a set of Docker images. It is free software (both as in free beer and as in free speech), open to suggestions and external contributions. The project aims at providing people with an easily setup, easily maintained and full-featured mail server while not shipping proprietary software nor unrelated features often found in popular groupware.

Postscreen

Postscreen is an SMTP filter that blocks spambots (or zombie machines) away from the real Postfix smtpd daemon, so Postfix does not feel overloaded and can process legitimate emails more efficiently.

The example below shows a typical spambot attempt at accessing the SMTP service and being stopped...

Jun 24 10:42:26 mail postfix/postscreen[203907]: CONNECT from [212.70.149.56]:19452 to [172.23.0.2]:25

Jun 24 10:42:26 mail postfix/dnsblog[386155]: addr 212.70.149.56 listed by domain psbl.surriel.com as 127.0.0.2
Jun 24 10:42:29 mail postfix/postscreen[203907]: PREGREET 11 after 2.9 from [212.70.149.56]:19452: EHLO User\r\n
Jun 24 10:42:29 mail postfix/postscreen[203907]: DISCONNECT [212.70.149.56]:19452

Postscreen is enabled by default but there are a few settings to tweak to get the best out of it.

Edit your data/config/postfix-main.cf file and add the following lines, making sure your Docker host IP is in bold...

mynetworks = 127.0.0.0/8 [::1]/128 [fe80::]/64 172.19.0.2/32 172.19.0.1/32
postscreen_greet_action = drop
postscreen_pipelining_enable = yes
postscreen_pipelining_action = drop
postscreen_non_smtp_command_enable = yes
postscreen_non_smtp_command_action = drop
postscreen_bare_newline_enable = yes 
postscreen_bare_newline_action = drop

MakeMKV

This will NOT work on a Raspberry Pi.

Use this in combination with ffmpeg or HandBrake (as shown below) and FileBot to process your media through to your media server - like Emby or Plex..

MakeMKV > HandBrake > FileBot > Emby

To make this work with your DVD drive (/dev/sr0) you need to have the second device (/dev/sg0) in order for it to work. I don't get it, but it works.

Troubleshooting

PROBLEM = "driver failed programming external connectivity on endpoint makemkv: Error starting userland proxy: listen tcp6 [::]:5800: socket: address family not supported by protocol."

SOLUTION = Put 0.0.0.0:5801 in the published ports line of docker compose to restrict the network to IPv4.

HandBrake

This will NOT work on a Raspberry Pi.

Use this in combination with ffmpeg or MakeMKV (as shown below) and FileBot to process your media through to your media server - like Emby or Plex..

I have changed the port from 5800 to 5802 because Jocelyn's other Docker image for MakeMKV uses the same port (so I move that one as well to 5801 - see above).

To make this work with your DVD drive (/dev/sr0) you need to have the second device (/dev/sg0) in order for it to work. I don't get it, but it works.

Automated Downloader

This takes the hassle out of going through the various web sites to find stuff and be bombarded with ads and pop-ups.

FlareSolverr
Jackett
Radarr
Transmission

FlareSolverr > Jackett > Radarr > Transmission

Create a docker network which Jackett and Radarr share to talk to each other...

sudo docker network create jackett-radarr

...then continue setting up the containers below.

FlareSolverr

FlareSolverr starts a proxy server and it waits for user requests in an idle state using few resources. When some request arrives, it uses puppeteer with the stealth plugin to create a headless browser (Chrome). It opens the URL with user parameters and waits until the Cloudflare challenge is solved (or timeout). The HTML code and the cookies are sent back to the user, and those cookies can be used to bypass Cloudflare using other HTTP clients.

Radarr > Jackett > FlareSolverr > Internet

https://github.com/FlareSolverr/FlareSolverr

https://hub.docker.com/r/flaresolverr/flaresolverr

Some indexers are protected by CloudFlare or similar services and Jackett is not able to solve the challenges. For these cases, FlareSolverr has been integrated into Jackett. This service is in charge of solving the challenges and configuring Jackett with the necessary cookies. Setting up this service is optional, most indexers don't need it.

Install FlareSolverr service using a Docker container, then configure FlareSolverr API URL in Jackett. For example: http://172.17.0.2:8191

Command line...

docker run -d \
 --name=flaresolverr \
 -p 8191:8191 \
 -e LOG_LEVEL=info \

      - TZ=Europe/London
    ports:
      - "${PORT:-8191}:8191"
    restart: unless-stopped

Jackett

Jackett works as a proxy server: it translates queries from apps (Sonarr, SickRage, CouchPotato, Mylar, etc) into tracker-site-specific http queries, parses the html response, then sends results back to the requesting software. This allows for getting recent uploads (like RSS) and performing searches. Jackett is a single repository of maintained indexer scraping and translation logic - removing the burden from other apps.

So, this is where you build your list of web sites "with content you want" ;-)

Radarr

Radarr is a movie collection manager for Usenet and BitTorrent users. It can monitor multiple RSS feeds for new movies and will interface with clients and indexers to grab, sort, and rename them. It can also be configured to automatically upgrade the quality of existing files in the library when a better quality format becomes available.

Radarr is the 'man-in-the-middle' to take lists from Jackett and pass them to Transmission to download.

Radarr is the web UI to search for "the content you want" ;-)

So, you use Jackett as an Indexer of content, which answers questions from Radarr, which passes a good result to Transmission...

Start it with no volume mounts, then copy the etc directory to your host...

cd /root/docker/stacks/nagios/
docker cp nagios:/opt/nagios/etc data/
chown -R 999:1000 data/

...then uncomment the # lines in the docker-compose file and restart the container.

Credentials

The default credentials for the web interface is nagiosadmin / nagios

To change the password, generate a new one by logging in to the container and running 'htpasswd'...

docker exec -it nagios bash
htpasswd -n nagiosadmin
(copy the output)

...then editing the /opt/nagios/etc/htpasswd.users file and refreshing the admin web page.

NextCloud

Nextcloud gives you access to all your files wherever you are.

Create your container folders...

mkdir -p /root/docker/stacks/nextcloud/data/{config,files}
chown -R 1000:1000 /root/docker/stacks/nextcloud/data/

/root/docker/stacks/nextcloud/docker-compose.yml

version: "2.1"
services:
  nextcloud:
    image: ghcr.io/linuxserver/nextcloud
    container_name: nextcloud
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
    volumes:
      - ./data/config:/config
      - ./data/files:/data
    ports:
      - 4443:443
    restart: unless-stopped

(I have changed the default port it listens on the local machine to 4443 but if you don't need any ports open then change the lines to:-

    expose:
      - 443

...then use Nginx Proxy Manager to direct traffic to your NextCloud installation)

Now visit https://ip.address.of.host:4443

...and on that setup page, _untick_ the option for "Install recommended apps" which does not install Calendar, Contacts, Mail, Chat, etc.

Enjoy.

Project Send

Self-hosted file sharing... small, simple, secure.

https://www.projectsend.org

https://docs.linuxserver.io/images/docker-projectsend

https://github.com/linuxserver/docker-projectsend

What they don't tell you in the docs is that you need a database backend - which is not in the docker compose file.

So, we just add a MariaDB database container to the stack!

Create your subdomain A record in DNS...

cli53 rrcreate domain.uk 'send 300 A 123.45.678.90'

Create your Proxy Host in Ngnix Proxy Manager with an SSL...

https://send.domain.uk

Create directories on the server for the Docker container files...

sudo -i
mkdir -p /root/docker/stacks/projectsend/data/{config,db,files}
chown -R 1000:1000 /root/docker/stacks/projectsend/data/files

/root/docker/stacks/projectsend/docker-compose.yml

version: "2.1"
services:
  projectsend:
    image: ghcr.io/linuxserver/projectsend
    container_name: projectsend
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
      - MAX_UPLOAD=100
    volumes:
      - ./data/config:/config
      - ./data/files:/data
      - /etc/timezone:/etc/timezone:ro
    expose:
      - 80
    restart: unless-stopped
  projectsend-db:
    image: mariadb
    container_name: projectsend-db
    environment:
      TZ: Europe/London
      MYSQL_ROOT_PASSWORD: projectsend
      MYSQL_DATABASE: projectsend
      MYSQL_USER: projectsend
      MYSQL_PASSWORD: projectsend
    volumes:
      - ./data/db:/var/lib/mysql
      - /etc/timezone:/etc/timezone:ro
    restart: unless-stopped
networks:
  default:
    external:
      name: nginx-proxy-manager

Go to the secure web site URL and complete the installation, using the Docker container name for the 'Database hostname'.

projectsend-db

Then, log in with your Admin username and password...

Create Group 'Public' which is public.
Create Group 'Customers' which is not public.
Create Client 'Customer Name' which is assigned to the 'Customers' group.
Upload some files and test both the Public and Client links.

Enjoy.

Troubleshooting

Change the Site URL

If you move host or domain name, you can log in to the DB container and change the 'base_uri'...

docker exec -it projectsend-db bash
mysql -u root -p projectsend

MariaDB [projectsend]> 
MariaDB [projectsend]> select * from tbl_options where name = 'base_uri';
+----+----------+-------------------------+
| id | name     | value                   |
+----+----------+-------------------------+
|  1 | base_uri | https://send.domain.uk/ |
+----+----------+-------------------------+

MediaWiki

Installation

Create the docker compose file and use default volume. Go to your browser at http://localhost:8080 and finish setup. Download LocalSettings.php file and copy to it to the container filesystem, then copy the whole folder to the host filsystem...

docker cp LocalSettings.php mediawiki:/var/www/html/
docker cp mediawiki:/var/www/html /root/docker/stacks/mediawiki/data/
chown -R www-data:www-data data/html
chmod o-w data/html
docker-compose down
(then edit your docker-compose.yml file so that local folders are used)
docker-compose up -d

Now, all the files are on your docker folder, ready to easily backup :-)
