Symbol Shoestring Deployment Tool

Security

[!IMPORTANT] CLI commands will generate unencrypted PEM file by default. The file specified via the argument --ca-key-path is expected to contain the main private key. This file itself is NOT needed to run the node and can be removed after the node is properly configured.

Additionally, the pemtool command can produce a encrypted PEM file, which is supported by all CLI commands.

In order to limit security risk, it is recommended to:

1. Make sure to back up ca.key.pem
2. Remove ca.key.pem after node setup
3. Use an encrypted PEM file if main account is sufficient valuable.

[!WARNING] shoestring.wizard does not currently support encrypted PEM files because there is no password input currently.

PEM files

To import existing private key and optionally encrypt it, we recommend using pemtool command, described below in pemtool section.

OpenSSL can be used to inspect the contents of a PEM file.

To print the public key only:

openssl pkey -in PEM_FILE.pem -noout -text_pub

To print both the private key and public key:

openssl pkey -in PEM_FILE.pem -noout -text

OpenSSL can also be used to generate completely new key:

openssl genpkey -algorithm ed25519 -out ca.key.pem

To generate new encrypted key:

openssl genpkey -algorithm ed25519 -out ca.key.pem -pass OPTIONS-FOLLOW

For details on openssl -pass switch we refer to openssl passphrase documentation.

Tips

If you are setting up a new node from scratch, it is recommended to use init and setup.

If you are setting up a new node but have existing harvesting and/or voting keys, it is recommended to update the imports section of the shoestring configuration file downloaded by init before running setup.

If you need to renew voting key files, it is recommended to use renew-voting-keys. This command will unregister all expired voting keys and register a new set of voting keys starting at first epoch without a registered voting key.

CLI Commands

In commands that require --package switch, the list of currently supported network aliases are:

• mainnet
• sai (current testnet)

As documented below, alternatively full path to package zip file can be provided using file:///filename or http(s)://.

Files

Shoestring Configuration INI

INI file used by shoestring to customize a Symbol node deployment. It is composed of five sections: network, images, services, transaction, imports, node.

network

Describes properties of network that deployed node should connect with. These should match values in config-network.properties Symbol configuration file. If init command is used, these values shouldn't be modified

name                  Network name
identifier            Network numeric identifier
epochAdjustment       Network epoch adjustment
generationHashSeed    Network generation hash seed

images

Describes Symbol docker images to use. If init command is used, these values shouldn't be modified

client  Catapult client docker image
rest    REST docker image

services

Describes network services to use during deployment. If init command is used, these values shouldn't be modified

nodewatch  URL to nodewatch service.

transactions

Describes properties of generated transactions. If init command is used, most of these values generally shouldn't be modified. min-cosignatures-count command can be used to automatically update minCosignaturesCount setting.

General properties:

feeMultiplier             Min fee multiplier of generated transactions
timeoutHours              Timeout of generated transactions (in hours)
minCosignaturesCount      Minimum number of cosignatures generated transactions will require

When signer command is signing an aggregate bonded transaction, it will additionally generate a hash lock transaction using the following properties:

hashLockDuration          Hash lock duration in blocks
currencyMosaicId          Network currency mosaid id
lockedFundsPerAggregate   Locked funds per aggregate

imports

Describes keys to import. These need to be manually set if there are harvesting and/or voting keys that need to be imported.

harvester Path to a config-harvesting.properties Symbol configuration file containing harvesting keys to import
voter     Path to a directory containing private_key_tree*.day files to import

node

Describes settings to customize a node.

features supports the following:

• PEER - Peer support
• API - REST support
• HARVESTER - Node will be configured to harvest and accept delegated harvesters
• VOTER - Node will be configured to vote

caPassword supports all available openssl passphrase options: https://www.openssl.org/docs/man3.0/man1/openssl-passphrase-options.html.

features       One or more node features to deploy (| delimited)
userId         User id of node used to set process and file permissons
groupId        Group id of node used to set process and file permissons
caPassword     Password of CA (main) PEM private key file (if applicable)
apiHttps       Set to enable HTTPS REST (only applicable when features include API)

caCommonName   Common name of generated CA certificates
nodeCommonName Common name of generated Node certificates

Overrides

INI file that is used to customize advanced Symbol settings.

Sections should have the format [<config-short-name>.<config-section>]. Section contents will then be applied to the appropriate Symbol configuration file.

For example, in order to set two custom settings:

1. connectTimeout - located in the config-node.properties file in section node
2. maxUnlockedAccounts - located in the config-harvesting.properties file in section harvesting

The following snippet will suffice:

[node.node]

connectTimeout = 5s

[harvesting.harvesting]

maxUnlockedAccounts = 2

Notice that these custom settings are applied BEFORE shoestring updates the Symbol configuration files. In cases of conflicts, the shoestring changes will take precedence.

Node Metadata

JSON file that is ingested and used to replace the contents of nodeMetadata in rest.json. This data is then accessible via the node/metadata REST endpoint. This file is optional and only used for deployments including API role.
