Usage

The container can either be used as a classic headless wallet or a masternode, only the command arguments will differ.

Headless wallet

1. Run a wallet container and specify at least the rpcuser and rpcpassword to interact with the Sparks daemon:

docker run --name sparks-wallet --restart always -d lepetitbloc/sparksd:v0.12.3.2 -rpcuser=sparks-wallet -rpcpassword=uxwuvl94

We recommend to mount a volume for easier access to the data and the configuration files. You should also create a configuration for your RPC credentials (see ./wallet/.sparkscore/sparks.conf) to avoid retyping them when using the internal sparks-cli.

docker run --name sparks-wallet --restart always -d -v ${PWD}/wallet/:/home/sparks/ lepetitbloc/sparksd:v0.12.3.2

⚠️ Ensure that a data directory exists and is writable in the mounted host directory.

2. Once your wallet is running, you can print your main address:

docker exec sparks-wallet sparks-cli getaccountaddress ""

2. Encrypt your wallet:

You can use pwgen first to generate your passphrase:

pwgen 32 1

quohd4kaw9guvi8ie7phaighawaiLoo6

docker exec sparks-wallet sparks-cli encryptwallet quohd4kaw9guvi8ie7phaighawaiLoo6

Wallet encrypted; Sparks Core server stopping, restart to run with encrypted wallet. The keypool has been flushed, you need to make a new backup.

‼️ Don't forget to backup your passphrase.

Masternode

Prerequisites

1. You must have received 1000 SPK on your wallet in a single transaction, and must have waited for, at least, 1 confirmation.

Note1: If the 1000 SPK came from multiple transactions, you can send them back to yourself.

Note2: Beware of the transaction cost, you should own 1001 SPK as a safety measure.

2. Only then you may find the corresponding transaction hash and index :

docker exec sparks-wallet sparks-cli masternode outputs

{
 "8e835a7d867d335434925c32f38902268e131e99a5821557d3e77f8ca3829fd8" : "0"
}

3. Then generate a masternode private key:

masternode genkey

7ev3RXQXYfztreEz8wmPKgJUpNiqkAkkdxt24C3ZKtg5qEVfou9

4. And finally creates the ./wallet/.sparkscore//masternode.conf file, and fill in following this template:

mn01 masternode:21529 YouMasterNodePrivateKey TransactionHash 0 YourWalletAddress:100

touch ./wallet/.sparkscore//masternode.conf

Setup

1. As a classic wallet, create a ./masternode/.sparkscore/sparks.conf configuration file

rpcuser=sparks-mn01
rpcpassword=uxwuvl94
masternode=1
masternodeprivkey=7ev3RXQXYfztreEz8wmPKgJUpNiqkAkkdxt24C3ZKtg5qEVfou9
externalip=YOUR.EXTERNAL.IP:8890

2. Run a container as a masternode:

docker run --name sparks-masternode --restart always -d -p 8890:8890 -p 8892:8892 -v ${PWD}/masternode/:/home/sparks/ lepetitbloc/sparksd:v0.12.3.2 -masternode=1

3. Check the the number of blocks until the chain is sync:

docker exec sparks-masternode sparks-cli getinfo

4. Once the chain synced you can start the masternode from your wallet:

docker exec sparks-wallet sparks-cli sparks-masternode start-all

You might need to unlock your wallet first:

 docker exec sparks-wallet sparks-cli walletpassphrase quohd4kaw9guvi8ie7phaighawaiLoo6 60

⚠️ Mind the space before the command above, that's not a typo, it’s meant to avoid storing your passphrase in history.

5. Then check the masternode status with your initial transaction hash:

docker exec sparks-wallet sparks-cli masternodelist | grep 6d94f70499c3f7ba2c59acaa5c04e54ef123d0e460bb07c55ace6464deaf3c85

"6d94f70499c3f7ba2c59acaa5c04e54ef123d0e460bb07c55ace6464deaf3c85-1": "ENABLED",

docker-compose

You could setup both at the same time using docker-compose. Check the provided docker-compose.yml as an example and tweak it to your needs!

docker-compose up --build
