Split container setup

This will setup Basicswap so that each coin runs in it's own container.

Install dependencies:

sudo apt install basez docker-compose

Copy and edit .env config:

cp example.env .env

Optionally set random RPC passwords:

for KEY in $(grep -o '^.*_RPC_PWD' .env)
do
    echo "Replacing: $KEY"
    NEW_PWD=$(cat /dev/random | base16 | head -c 48)
    sed -i "s/${KEY}=.*$/${KEY}=${NEW_PWD}/g" .env
done

Set the latest Monero chain height, or the height your wallet must restore from:

echo "DEFAULT_XMR_RESTORE_HEIGHT=$(curl https://localmonero.co/blocks/api/get_stats | jq .height)" >> .env

Create docker-compose config:

cat compose-fragments/0_start.yml > docker-compose.yml

# Add the relevant coin fragments
cat compose-fragments/1_bitcoin.yml >> docker-compose.yml
cat compose-fragments/1_litecoin.yml >> docker-compose.yml
cat compose-fragments/1_monero-wallet.yml >> docker-compose.yml
cat compose-fragments/1_pivx.yml >> docker-compose.yml
cat compose-fragments/1_dash.yml >> docker-compose.yml
cat compose-fragments/1_firo.yml >> docker-compose.yml

# Copy for prepare script config
cp docker-compose.yml docker-compose-prepare.yml
cat compose-fragments/9_swapprepare.yml >> docker-compose-prepare.yml

# Add the Monero daemon if required (should not go in docker-compose-prepare.yml)
cat compose-fragments/8_monero-daemon.yml >> docker-compose.yml

# Add the swapclient
cat compose-fragments/8_swapclient.yml >> docker-compose.yml

Create the docker network, with a specific subnet (for optional tor use):

docker network create coinswap_network --subnet="172.16.238.0/24"

Build the swapclient container:

docker-compose build swapclient

Build the monero container, if required:

docker-compose build monero_daemon

Build the remaining coin containers:

docker-compose build

Build the prepare-only containers:

docker-compose -f docker-compose-prepare.yml build

Create config files:

# Select relevant coins:
export WITH_COINS=bitcoin,litecoin,monero

docker-compose -f docker-compose-prepare.yml run --rm swapprepare \
    basicswap-prepare --nocores --withcoins=${WITH_COINS} --htmlhost="0.0.0.0" --particl_mnemonic=none

Start coin cores only:

docker-compose -f docker-compose-prepare.yml up -d --scale swapprepare=0

Initialise wallets:

docker-compose -f docker-compose-prepare.yml run --rm swapprepare \
    basicswap-prepare --initwalletsonly

Stop cores:

docker-compose -f docker-compose-prepare.yml stop

Start BasicSwap:

docker-compose up

Update code

docker-compose stop

pushd .
cd ../../
git pull
popd

docker-compose build monero_daemon
docker-compose build

docker-compose build --no-cache swapclient
docker-compose up

Add a coin

cat compose-fragments/1_monero-wallet.yml >> docker-compose.yml
cat compose-fragments/1_monero-wallet.yml >> docker-compose-prepare.yml

# Add the Monero daemon if required (should not go in docker-compose-prepare.yml)
cat compose-fragments/8_monero-daemon.yml >> docker-compose.yml



export ADD_COIN=monero
docker-compose -f docker-compose-prepare.yml run --rm swapprepare \
    basicswap-prepare --nocores --addcoin=${ADD_COIN} --htmlhost="0.0.0.0" --particl_mnemonic=none

docker-compose build monero_daemon
docker-compose build

docker-compose -f docker-compose-prepare.yml up -d --scale swapprepare=0

docker-compose -f docker-compose-prepare.yml run -e WALLET_ENCRYPTION_PWD=walletpass \
    --rm swapprepare \
    basicswap-prepare --initwalletsonly --withoutcoin=particl --withcoin=monero

docker-compose -f docker-compose-prepare.yml stop

docker-compose up
