Move Dojo bitcoind container data to host machine

#### Move your bitcoind data from the Dojo's bitcoind docker container, to outside of the container on your host machine ####

## Written for use with Ubuntu Desktop 18.04 LTS & Dojo v1.0.0 ##

## Start Dojo
$ cd /path/to/docker/my-dojo/ && sudo ./dojo.sh start

## Login to the bitcoind docker container as root
$ sudo docker exec -u root -it bitcoind /bin/bash

## Update and install a text editor
$ apt-get update && apt-get install nano

## Stopping bitcoind via 'sudo ./dojo.sh bitcoin-cli stop' shuts the container down, so I found it easiest to
## just add the following to bitcoin.conf and then stop the tor container to cut internet so the bitcoind
## container won't be able to download anything while moving the .bitcoin directory
## In [terminal Doc]
$ nano /home/bitcoin/.bitcoin/bitcoin.conf

    ## Add to bitcoin.conf
    onlynet=onion
    dnsseed=0
    dns=0

    ## Save and exit
    ctrl+x --> y --> return
    
## Make a new directory in the bitcoind container to mount a host directory to
$ mkdir /mnt/bitcoin_data

## Exit the bitcoind container
$ exit

## Stop Dojo
$ sudo ./dojo.sh stop

## Make a new directory in your /path/to/docker/my-dojo/ directory to bind to the bitcoind container
## and create a test file to make sure it mounted properly
## *** your current working directory should be /path/to/docker/my-dojo/ ***
$ mkdir bitcoin_data
$ touch bitcoin_data/test

## Modify the docker-compose.yaml file to bind mount a host directory to a bitcoind container directory

	## Under the section for `bitcoind` --> `volumes:` add:
	- ./bitcoin_data:/mnt/bitcoin_data


	#### Your bitcoind section should now look something like the following ####
	bitcoind:
	  image: "samouraiwallet/dojo-bitcoind:1.0.0"
	  container_name: bitcoind
	  build:
	    context: ./bitcoin
	  env_file:
	    - ./.env
	    - ./conf/docker-bitcoind.conf
	  restart: on-failure
	  command: "/wait-for-it.sh tor:9050 --timeout=360 --strict -- /restart.sh"
	  expose:
	    - "28256"
	    - "9501"
	    - "9502"
	  volumes:
	    - ./bitcoin_data:/mnt/bitcoin_data
	    - data-bitcoind:/home/bitcoin/.bitcoin
	  depends_on:
	    - db
	    - tor
	  networks:
	    dojonet:
	      ipv4_address: 172.28.1.5


	## Save and exit
	ctrl+x --> y --> return

## Start Dojo
$ sudo ./dojo.sh start

## Pause the TOR container. This will stop bitcoind from downloading anything b/c it won't have an internet connection
$ sudo docker container pause tor

## Login to bitcoind container as root
$ sudo docker exec -u root -it bitcoind /bin/bash

## Ensure that things mounted properly
$ cd /mnt/bitcoin_data
$ ls -la

	## You should see the `test` file we created earlier. You can remove it now.
	$ rm -rf test

## Move the .bitcoin directory to your bind mounted directory
$ mv /home/bitcoin/.bitcoin/ /mnt/bitcoin_data/

## This takes a bit, and seemed like it locked up my computer but it did not. Be patient.
## Took my pc about 15 minutes on an SSD.

## Open another terminal [ctrl + alt + t] and make sure the files are there
$ cd /home/path/to/docker/my-dojo/
$ du -h bitcoin_data

	## As of June 2019, my .bitcoin directory was 263G

## Exit that new terminal you just opened
$ exit

## Switching back to your previous terminal and exit the docker container
$ exit

## Stop Dojo
$ sudo ./dojo.sh start

## Move files to your host system's home folder
$ cd bitcoin_data
$ sudo mv .bitcoin ~

## Change ownership of everything to your current user
$ sudo chown $USER:$USER ~/.bitcoin/*
$ sudo chown $USER:$USER ~/.bitcoin/blocks/*
$ sudo chown $USER:$USER ~/.bitcoin/blocks/index/*
$ sudo chown $USER:$USER ~/.bitcoin/chainstate/*
$ sudo chown $USER:$USER ~/.bitcoin/indexes/*
$ sudo chown $USER:$USER ~/.bitcoin/indexes/txindex/*
$ sudo chown $USER:$USER ~/.bitcoin/wallets/*

##### If there are issues with changing ownership of the txindex/* files (Arguments being too long), try the following:
$ sudo find ~/.bitcoin/indexes/txindex/ -type f -exec chown $USER:$USER {} \;

## Remove the `.lock` , `.pid` , and `.walletlock` files
$ rm -rf ~/.bitcoin/.lock
$ rm -rf ~/.bitcoin/bitcoind.pid
$ rm -rf ~/wallets/.walletlock

## Modify bitcoin.conf (it might need to be modified again if installing the next Dojo release which can be installed ontop
## of an already existing bitcoind instance. Follow those directions when doing so for modifying bitcoin.conf as needed).
$ nano ~/.bitcoin/bitcoin.conf

Begin sample bitcoin.conf file
-----------------------------------------------------------------------------------------------------------------------------
# Bitcoin Configuration

End bitcoin.conf file

## Note: if you've previously followed my guide for installing Electrs (Electrum Personal Server), as well as LND with
## Dojo v1.0.0, you will **NOT** have to change the configurations for either of those **IF** you use the above .conf file.
## If you do need to modify them to work with the standard bitcoindrpc port (default is 8332), those files can be found at:
		$ nano ~/.lnd/lnd.conf
		$ sudo nano /usr/share/applications/electrum-personal-server.desktop

########## Install Tor ############################################################################################################
