Fnet dockerized algod

Overview

A set of scripts to configure and run a dockerized algod for FNet.

Getting Started

Use the run script to configure and launch an FNet node

./run.sh

Automatic Updates

To update your node automatically, set up a cron job to execute auto-update.sh

The Fnet network may be reset. The scripts support automatically resetting the node to follow along with the new network.

The on-network-reset.sh script can also be utilized to bootstrap some user actions when a new instance of the network is created, such as keyreg online, create applications, fund other addresses, etc.

KMD & Participation keys

A default passwordless KMD will be available in the container. Accounts you import will be persisted when you reset the network data dir (through utils/reset.sh)

Participation keys in partkeys/ will be copied into the data directory and automatically installed when the node first boots (without network data state). If you generate participation keys after booting your node, you can reset it with ./utils/reset.sh -y and it will import the participation keys the next time you run ./run.sh. Note: the filename is required to follow this format: [name].[first round].[last round].partkey e.g. 2AQQU742K66T26EUYXH7CB3D4TL5KG7GN3S52CJZAYHDVQ76HFPSWCJUJ4.0.1000000.partkey

Participation keyfiles (.partkey) can be generated standalone using utils/algokey, e.g. algokey part generate --parent 2AQQU742K66T26EUYXH7CB3D4TL5KG7GN3S52CJZAYHDVQ76HFPSWCJUJ4 --first 0 --last 1000000 --dilution 1000 --keyfile 2AQQU742K66T26EUYXH7CB3D4TL5KG7GN3S52CJZAYHDVQ76HFPSWCJUJ4.0.1000000.partkey

Table of Contents

These scripts are to be run on your host machine.

./run.sh Entry point. Configures a local docker algod instance and starts it

./stop.sh stops the docker instance

./goal.sh wraps goal, e.g. ./goal.sh node status. It can also be piped to, e.g. echo "apple apple ..." | ./goal.sh account import

./auto-update.sh should be cronned to check for upstream network resets. When it finds a different genesis file, it will reset the node (wiping all local data) and restart it with the new genesis file. 👉 Finally it will run the on-network-reset.sh script, where you can place any bootstrap commands you want to execute when the network resets, e.g. waiting for funds and registering online. If you import accounts to goal/kmd, these will be persisted through resets.

Utilities

These scripts are to be run on your host machine.

./utils/shell.sh starts a shell in the docker container

./utils/reset.sh clears local algod data and genesis file and restarts the node. Does not reset KMD data. This is required if genesis has changed since you last ran your node.

./utils/catchup.sh Starts fast catchup, waits for sync.

./utils/create_tokens.sh Creates algod.token and algod.admin.token

./utils/get_account_eligibility.sh $account Gets the specified $account's incentives eligibility.

./utils/get_balance.sh $account Gets microALGO balance of account $account through local node

./utils/get_genesis.sh Fetches latest genesis file from a relay

./utils/is_node_running.sh Exits successfully if node is running and ready

./utils/is_node_syncing.sh Exits successfully if node is syncing

./utils/wait_for_balance.sh $account $amount Waits until account $account has a balance of at least $amount

./utils/wait_node_start.sh Waits briefly for the node to start

./utils/wait_sync.sh $timeout Waits for node to sync, optionally with timeout of $timeout seconds

./utils/wipe.sh Resets the repository to initial state (note: also wipes KMD)
