Move bitcoind data to Dojo bitcoind container

#### Move over block data to your Dojo ####

	## If you wanted to copy over the data instead of moving it, see --> https://gist.github.com/05nelsonm/96ad8da7724de3a66f44d6c2d70b361c

## Written for 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
$ 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

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

	## Be sure to enter the full path below to wherever your /.bitcoin/ directory is located (typically /home/your_username/.bitcoin/)
	## Under the section for `bitcoind` --> `volumes:` add...
	  - /home/path/to/host_machine/.bitcoin:/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:
	    - /home/path/to/host_machine/.bitcoin:/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

## Ensure bitcoind isn't doing anything by checking the bitcoind logs
$ sudo ./dojo.sh logs bitcoind

	## You should see socks errors and unable to connect statements

## 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 host machine's bitcoind files in there
		
## Clear out everything but `bitcoin.pid` and `bitcoin.conf` from the container's home/bitcoin/.bitcoin/ directory
$ mv /home/bitcoin/.bitcoin/bitcoin.conf /home/bitcoin/
$ mv /home/bitcoin/.bitcoin/bitcoind.pid /home/bitcoin/
$ rm -rf /home/bitcoin/.bitcoin/*

## Move over host machine .bitcoin files
$ mv /mnt/bitcoin_data/.bitcoin/ /home/bitcoin/.bitcoin/

## Remove old `bitcoin.conf` file that you moved over from your host machine, and then move your Dojo's files back
$ rm -rf /home/bitcoin/.bitcoin/bitcoin.conf
$ mv /home/bitcoin/bitcoin.conf /home/bitcoin/.bitcoin/
$ mv /home/bitcoin/bitcoind.pid /home/bitcoin/.bitcoin/

## Change ownership of everything to bitcoin:bitcoin
$ chown bitcoin:bitcoin /home/bitcoin/.bitcoin/*
$ chown bitcoin:bitcoin /home/bitcoin/.bitcoin/blocks/*
$ chown bitcoin:bitcoin /home/bitcoin/.bitcoin/blocks/index/*
$ chown bitcoin:bitcoin /home/bitcoin/.bitcoin/chainstate/*
$ chown bitcoin:bitcoin /home/bitcoin/.bitcoin/indexes/*
$ chown bitcoin:bitcoin /home/bitcoin/.bitcoin/indexes/txindex/*
$ chown bitcoin:bitcoin /home/bitcoin/.bitcoin/wallets/*

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

## Double check ownership of everything is bitcoin:bitcoin by going into each directory and executing
$ ls -la

## Reinstall the text editor (it gets uninstalled after Dojo restart)
$ apt-get update && apt-get install nano

## Revert your bitcoin.conf back to allow for clearnet connections
$ nano /home/bitcoin/.bitcoin/bitcoin.conf

    ## Remove from bitcoin.conf
    onlynet=onion
    dnsseed=0
    dns=0
    
    ## Save and exit
    ctrl+x --> y --> return
		
## Exit the container
$ exit

## Restart the Dojo
$ sudo ./dojo.sh stop
$ sudo ./dojo.sh start

## Check bitcoind progress
$ sudo ./dojo.sh logs bitcoind
