Part 11 - Node Operator's Configuration Guide for Dummies - Intro to the Command Line Interface


Part 11 - Intro to the Command Line Interface

Part 11 - Intro to the Command Line Interface


As a node operator, the CLI is your primary tool for interacting with Rocket Pool. You will use it to create new minipools, check on the status of everything, claim periodic RPL rewards, exit and withdraw from your minipools when you're ready and do a host of other activities.


Once you've finished syncing the ETH1 and ETH2 chains, all the commands will be available for you to use. In this section, we'll go over a brief tour of some of the more common ones and some other tricks that the CLI can do.

This lists out each of the available commands along with a shortcut for them (the letter next to them), as well as some advanced flags you can set when running a command. Below, we'll go through the common operations you can expect to use as a node operator.


Service Commands

The service group is all about managing the Rocket Pool services themselves. You've already done some of this during the initial setup process. To see them all, run:

 rocketpool service help 

The output will look like this:

NAME:
   rocketpool service - Manage Rocket Pool service

   --help, -h                      show help

status

This command shows you the current running status of each of the Docker containers managed by Rocket Pool. For example, the default Docker install's output looks like this:

        Name                       Command              State                                                       Ports                                                     
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
rocketpool_api          /bin/sleep infinity             Up                                                                                                                    
rocketpool_eth1         sh /setup/start-node.sh         Up      0.0.0.0:30303->30303/tcp,:::30303->30303/tcp, 0.0.0.0:30303->30303/udp,:::30303->30303/udp, 8545/tcp, 8546/tcp
rocketpool_eth2         sh /setup/start-beacon.sh       Up      0.0.0.0:9001->9001/tcp,:::9001->9001/tcp, 0.0.0.0:9001->9001/udp,:::9001->9001/udp                            
rocketpool_node         /go/bin/rocketpool node         Up                                                                                                                    
rocketpool_validator    sh /setup/start-validator.sh    Up                                                                                                                    
rocketpool_watchtower   /go/bin/rocketpool watchtower   Up

You can use it to quickly check if any of the Docker containers are having trouble or to make sure that a start or stop command worked correctly.


start and stop

These two commands you are already familiar with. They simply start all of the Rocket Pool containers or stop them.

TIP The pause command does the same thing as stop. It's just leftover as a legacy command from earlier versions of Rocket Pool.

logs

This command is another one you should have already seen. You can use it to look at the output logs of each Docker container. This can be useful for troubleshooting or getting a more detailed status report from them.


If you simply do rocketpool service logs without any other arguments, it will aggregate all of the logs together and show them to you at once.


If you want to focus on one container's output, you can add an argument to the end to specify the container. Valid values are eth1, eth2, validator, api, node, and watchtower.


stats

This command shows you some resource stats from each of the containers, which you can use to profile each one's hardware and network consumption.


You might find it useful for monitoring the containers if your system starts running slow or has RAM problems.


Here is some example output:

CONTAINER ID   NAME                    CPU %     MEM USAGE / LIMIT     MEM %     NET I/O           BLOCK I/O         PIDS

NOTE The RAM statistic here shows total allocated memory, which includes virtual memory. It does not show the raw resident memory consumption.
Similarly, the CPU usage shows the total amount of CPU consumption averaged over all of the CPU cores that the container uses. Here, the CPU for ETH2 shows almost 100% because it is using Nimbus, which is single-threaded.
You may find that a program like htop offers better insight into actual resource consumption.

config

This command runs through the configuration interview again. You can use it if you want to change your selection of ETH1 or ETH2 client, or change some of the parameters that you initially specified when you selected them (such as your validator's graffiti message, the max number of peers to connect to, and so on).


You can call this command at any time, but the changes won't take effect until you call rocketpool service stop and rocketpool service start.


terminate

This command will shut down the Docker containers, then delete them, delete the Rocket Pool virtual network, and delete the ETH1 and ETH2 chain data volumes. It essentially removes all of the Rocket Pool items from your Docker setup. Use it when you want to clean up that portion of the Rocket Pool installation.

WARNING This will irreversibly remove your chain data, which means you'll need to sync ETH1 and ETH2 again.
This will not remove your wallet and password files, your configured settings, or your validator keys. To remove those, you will need to delete the ~/.rocketpool/data folder in Docker or Hybrid Mode, or the corresponding directory in Native Mode.

Node Commands

The node group involves operations on your Rocket Pool node. We'll cover these more in-depth in the next section, where we create a minipool, but it may be helpful to see them all at a glance.


Here is what the rocketpool node help output will show:

NAME:
   rocketpool node - Manage the node

USAGE:
   rocketpool node [global options] command [command options] [arguments...]

VERSION:
   1.1.1

COMMANDS:
   status, s                      Get the node's status
   sync, y                        Get the sync progress of the eth1 and eth2 clients
   register, r                    Register the node with Rocket Pool
   rewards, e                     Get the time and your expected RPL rewards of the next checkpoint
   set-withdrawal-address, w      Set the node's withdrawal address
   confirm-withdrawal-address, f  Confirm the node's pending withdrawal address if it has been set back to the node's address itself
   set-timezone, t                Set the node's timezone location
   swap-rpl, p                    Swap old RPL for new RPL
   stake-rpl, k                   Stake RPL against the node
   claim-rpl, c                   Claim available RPL rewards for the current checkpoint
   withdraw-rpl, i                Withdraw RPL staked against the node
   deposit, d                     Make a deposit and create a minipool
   send, n                        Send ETH or tokens from the node account to an address

GLOBAL OPTIONS:
   --help, -h  show help

Below is a summary of some of the commands you'll tend to need during typical node operation.


status

This command will give you a high-level view of your entire node at a glance. It includes how much ETH and RPL you have staked, how many minipools you have and their statuses, your RPL collateral ratio, and more.


This is an example of what rocketpool node status shows once you have your node registered and some minipools set up:

The node <node address> has a balance of 852.221778 ETH and 4820.395655 RPL.

The node is registered with Rocket Pool with a timezone location of <timezone>.

The node has a total stake of 11763.477482 RPL and an effective stake of 11763.477482 RPL, allowing it to run 41 minipool(s) in total.
This is currently a 10.60% collateral ratio.
The node must keep at least 11094.621444 RPL staked to collateralize its minipools and claim RPL rewards.

The node has a total of 39 minipool(s):
- 1 staking
- 37 withdrawable (after withdrawal delay)
- 1 dissolved
* 37 minipool(s) are ready for withdrawal!
* 1 dissolved minipool(s) can be closed!


sync

This command will show you the current sync status of your ETH1 and ETH2 clients. You'll probably use it a lot when you first set the node up, then never need it again (unless you change or reset your clients).


The output of rocketpool node sync will look like this:

Your eth1 client is still syncing (76.26%). 
Your eth2 client is still syncing (39.92%). 

Note that Prysm currently doesn't provide its completion percent - you'll need to look in the eth2 logs if you use it.


stake-rpl

This command is what you'll use when you want to add more RPL collateral to your node. Doing so will increase your collateral ratio, which will increase your RPL rewards at each checkpoint (more on this later). It may allow you to run more minipools or withdraw your rewards for the current checkpoint if your collateral is currently too low.


Unlike the other commands so far, this one is actually interactive because it will trigger a transaction - it isn't simply informational.


It will first ask you how much RPL you'd like to stake, with some pre-defined options for convenience or the ability to specify a custom amount:

Please choose an amount of RPL to stake:
1: The minimum minipool stake amount (284.477473 RPL)?
2: The maximum effective minipool stake amount (4267.162095 RPL)?
3: Your entire RPL balance (4820.395655 RPL)?
4: A custom amount

Once you select an option, you will be shown some information about the suggested gas price and estimated amount to be used, along with a confirmation dialog:

Please enter an amount of RPL to stake:
0.00001

Suggested gas price: 1.000000 Gwei
Estimated gas used: 69484 gas
Estimated gas cost: 0.000069 ETH

NOTE: This operation requires multiple transactions.
The actual gas cost may be higher than what is estimated here.
Are you sure you want to stake 0.000010 RPL? You will not be able to unstake this RPL until you exit your validators and close your minipools, or reach over 150% collateral!. [y/n]

If you confirm, you will be shown the transaction hash and given a link to Etherscan, so you can follow its progress:

Approving RPL for staking...
Transaction has been submitted with hash <transaction hash>.
You may follow its progress by visiting:
https://goerli.etherscan.io/tx/<transaction hash>

Waiting for the transaction to be mined... **DO NOT EXIT!** This transaction is one of several that must be completed.

Most operations only require one transaction, so the CLI will wait until it has been mined and then exit. However, stake-rpl is one of the few commands that requires two transactions, so this dialog will appear twice.


deposit

This command will let you deposit ETH and create a new minipool (a new ETH2 validator). As with stake-rpl, this is an interactive command that will perform a transaction.


It will start by asking you how much you want to deposit to the new minipool:

Please choose an amount of ETH to deposit:
1: 32 ETH (minipool begins staking immediately)
2: 16 ETH (minipool begins staking after ETH is assigned)

(For more information on these options, see the section on Creating a Minipool).


Once you select your deposit amount, it will prompt you for your choice of commission rate slippage:

The current network node commission rate that your minipool should receive is 20.000000%.
The suggested maximum commission rate slippage for your deposit transaction is 1.000000%.
This will result in your minipool receiving a minimum possible commission rate of 19.000000%.
Do you want to use the suggested maximum commission rate slippage? [y/n]

After that, you will be prompted with the expected gas cost for the transaction and one final confirmation dialog. If you accept, your ETH deposit will be processed, and you will create a new minipool (and a corresponding ETH2 validator).


claim-rpl

This command lets you manually trigger an RPL rewards claim after an RPL checkpoint. This process is normally handled automatically by the rocketpool_node Docker container or process, but if you disable automatic claiming and prefer to do it manually, you can use this command to do it.


send

This command lets you send ETH, RPL, or other Rocket Pool-related tokens from the node wallet to a different address. This might be useful if you want to move your funds on the wallet elsewhere.

The syntax for using the send command is like this:

 rocketpool node send <amount> <token> <address> 

The arguments are as follows:

  • <amount> is the amount of the token to send.

  • <token> is the token to send - this can be eth, rpl, fsrpl (the old legacy RPL token), or reth.

  • <address> is the Ethereum address to send the tokens to.

For example:

 rocketpool node send 1 eth <my friend's address> 

would send 1 ETH to my friend.


Minipool Commands

The minipool group involves commands that affect your minipools.


Here is what the rocketpool minipool help output will show:

NAME:
   rocketpool minipool - Manage the node's minipools

USAGE:
   rocketpool minipool [global options] command [command options] [arguments...]

VERSION:
   1.1.1

COMMANDS:
   status, s                   Get a list of the node's minipools
   refund, r                   Refund ETH belonging to the node from minipools
   exit, e                     Exit staking minipools from the beacon chain
   delegate-upgrade, u         Upgrade a minipool's delegate contract to the latest version
   delegate-rollback, b        Roll a minipool's delegate contract back to its previous version
   set-use-latest-delegate, l  If enabled, the minipool will ignore its current delegate contract and always use whatever the latest delegate is
   find-vanity-address, v      Search for a custom vanity minipool address


GLOBAL OPTIONS:
   --help, -h  show help

Below is a summary of the commands that you'll typically use.


status

This command simply provides a summary of each of your minipools. This includes its current status, the eth1 address of the minipool, the commission on it (called the node fee), the public key of the corresponding ETH2 validator, and some other things:

$ rocketpool minipool status

1 Staking minipool(s):

--------------------

Address:              <minipool eth1 address>
Status updated:       2021-05-21, 14:05 +0000 UTC
Node fee:             20.000000%
Node deposit:         16.000000 ETH
RP ETH assigned:      2021-05-23, 13:32 +0000 UTC
RP deposit:           16.000000 ETH
Validator pubkey:     <validator eth2 address>
Validator index:      0
Validator seen:       yes

refund

This command lets you pull 16 ETH back from a minipool if you deposited 32 ETH to create one, once Rocket Pool was able to contribute 16 ETH from the rETH staking pool.


exit

This command submits a voluntary exit for your validator on the Beacon Chain. Use this when you want to close a validator and withdraw its final ETH balance. Note that this cannot be undone - once you trigger an exit, the validator will shut down permanently.


Useful Flags

There are some useful global flags that you can add to some of the above commands, which you may want to take advantage of.


Setting a Custom Max Fee or Priority Fee (Gas Price)

Starting with the London ETH1 hardfork in July 2021, Ethereum transactions no longer use a single gas price for their transactions. Instead, modern Ethereum transactions use two values:

  • The max fee, which describes the absolute maximum gas price you're willing to accept on a transaction

  • The max priority fee, which describes the maximum amount you're willing to "tip" the miner for including your transaction in a block

TIP The way these two values work can be a bit convoluted, so here are some simple examples.
Let's say the current network fee, called the base fee, is at 50 gwei. You submit a transaction with an 80 gwei max fee, and a priority fee of 2 gwei.
Because the network's base fee is lower than your max fee, this transaction could get picked up in the current block. It would cost you 50 gwei for the base fee and 2 gwei for the priority fee; even though you set your max fee to 80, it would only cost you 52 gwei total.
As another example, say you have that same transaction, but now the network's base fee is 100 gwei. Since 100 gwei is larger than your 80 gwei max fee, your transaction will not be included in this block. Instead, it will simply sit in the transaction pool until the base fee is low enough to include it.
Now, let's say the current base fee is 50 gwei again, and your transaction has a max fee of 80 gwei and a priority fee of 4 gwei. It would execute with a total cost of 54 gwei. The 4 gwei priority fee would ensure that it was included in front of all of the transactions with a lower priority fee.
If you really want the transaction to go through at all costs, you can set the priority fee to be the same as the max fee. This emulates the legacy gas behavior, so your transaction will use all the gas you give it - regardless of whether the network's base fee is lower than your max fee or not.

By default, Rocket Pool will use an oracle to look at the current transaction pool and suggest a reasonable max fee for any transactions you trigger. It uses EtherChain for its primary suggestion oracle, and Etherscan as a backup.


If you prefer, you can set a custom max fee (in gwei) you'd be willing to pay with the -f flag. You can also set a custom priority fee with the -i flag.


To do this, add them after rocketpool and before the other command information.


For example, calling node set-timezone with this flag would provide the following output:

$ rocketpool -f 10 node set-timezone

Would you like to detect your timezone automatically? [y/n]
n

Please enter a timezone to register with in the format 'Country/City':
Australia/Brisbane

You have chosen to register with the timezone 'Australia/Brisbane', is this correct? [y/n]
y

Using the requested max fee of 10.00 gwei (including a max priority fee of 2.00 gwei).
Total cost: 0.0005 to 0.0007 ETH
Are you sure you want to set your timezone? [y/n]

This shows that regardless of what max fee the network recommends, it will use your custom max fee of 10 gwei (and priority fee if you specify it) instead when submitting this transaction.

NOTE If you set a manual max fee, we strongly encourage you to use a third-party gas price oracle such as EtherChain to determine if that fee is high enough for the current network conditions before submitting the transaction.

Canceling / Overwriting a Stuck Transaction

Sometimes, you might run into a scenario where you sent a transaction to the network, but you used a gas price that is far too low for the network conditions, and it will take a prohibitively long time to execute. Since all of your subsequent transactions will wait until that one goes through, that transaction essentially blocks all of the operations on your Rocket Pool node. To deal with this situation, we've added a global flag that lets you "cancel" such a transaction by replacing it with something else.


Every Ethereum wallet, including your node wallet, sends transactions sequentially. Each transaction you send has a number called a nonce that identifies where it lives in that sequence. The very first transaction you send will have a nonce of 0, the next one you send will have a nonce of 1, and so on.


This overwriting technique involves sending a new transaction that uses the same nonce as your existing stuck transaction but will ideally include a higher gas price than the stuck one. This means that the new one will be mined first. As soon as it's mined into a block, the old one will be discarded from the network as though it was never sent in the first place.


To use this flag, you first need to find the nonce of your stuck transaction:

  1. Go to an ETH1 block explorer like https://etherscan.io

  2. Navigate to the address of your wallet, and look at the list of transactions.

  3. Go through them, starting with the most recent, until you find the furthest one down the list that has the Pending state.

  4. Mark the nonce of that transaction. That's what you'll need.

Once you have it, simply call any transaction with the CLI using the --nonce <value> -i 2.2 flags after rocketpool and before the rest of the command.

NOTE You must include the -i (priority fee) flag in order to overwrite a previous transaction. This number must be at least 10% higher than whatever priority fee your old transaction used. The Smartnode uses a priority fee of 2 gwei by default, so a value of 2.2 is usually sufficient for an override.
If your old transaction used a custom fee (say, 10 gwei), you will need to set it at least 10% higher in the overriding transaction (so in this example, 11 gwei).

As an example, say I submitted a transaction with a nonce of 10 and a max fee of 20 gwei, but the current network fee is 100 gwei so my transaction is stuck. To fix it, I will submit a transaction where I send a small amount of ETH from myself back to myself with a higher max fee (say, 150 gwei) and a higher priority fee. I'll burn a little gas doing it, but it will unstick the broken transaction:

$ rocketpool --nonce 10 -f 150 -i 2.2 node send 0.0001 eth <node wallet address>

Using the requested max fee of 150.00 gwei (including a max priority fee of 2.20 gwei).
Total cost: 0.0032 to 0.0032 ETH
Are you sure you want to send 0.000100 eth to <node wallet address>? This action cannot be undone! [y/n]

The Smartnode stack will automatically check to make sure that the nonce you have provided is valid (it refers to a pending transaction) before sending it and wasting your gas accidentally. If not, it will return an error message. Otherwise, it will go through and provide you with the transaction details, so you can monitor it to confirm that it did, in fact, overwrite your old stuck transaction.


That's it for the common CLI commands.
