Safenode Manager
Safenode Manager is a command-line application for installing, managing, and operating safenode as a service.
It runs on Linux, macOS and Windows.
Installation
The latest version can be installed via safeup:
safeup node-manager
A binary can also be obtained for your platform from the releases in this repository.
Nodes as Services
The primary use case for Safenode Manager is to setup safenode as a long-running background service, using the service infrastructure provided by the operating system.
Create Services
First, use the add command to create some services:
$ sudo safenode-manager add --count 3 --peer /ip4/46.101.80.187/udp/58070/quic-v1/p2p/12D3KooWKgJQedzCxrp33u3dBD1mUZ9HTjEjgrxskEBvzoQWkRT9
This downloads the latest version of the safenode binary and creates three services that will initially connect to the specified peer. Soon, specification of a peer will not be required.
There are many arguments available for customising the service. For example, you can choose the port the node will run on, or the version of safenode. Run safenode-manager add --help to see all available options.
Note: elevated privileges are required for creating services, on all platforms.
Now run the status command:
$ safenode-manager status
=================================================
Safenode Services

Service Name Peer ID Status Connected Peers
safenode1 - ADDED -
safenode2 - ADDED -
safenode3 - ADDED -
We can see the services have been added, but they are not running yet.
Start Services
Use the start command to start each service:
$ sudo safenode-manager start
Providing no arguments will start all available services. If need be, it's possible to start services individually, using the --service-name argument.
With the services started, run the status command again:
$ safenode-manager status

We can see our services are running and the nodes have connections to other peers.
Now, run the status command again, but with the --details flag:

We get some more details for each node, including the path to its logs. Using the location provided, feel free to take a look at the logs being generated by the node.
The nodes could now be left running like this, but for the purposes of this guide, we will do some more things.
Add More Nodes
It's possible to run the add command again, as before:
sudo safenode-manager add --count 3 --peer /ip4/46.101.80.187/udp/58070/quic-v1/p2p/12D3KooWKgJQedzCxrp33u3dBD1mUZ9HTjEjgrxskEBvzoQWkRT9
The subsequent status command will show us an additional three nodes, for a total of six:
$ safenode-manager status

Again, the new nodes have not been started.
Run the start command to start them, then observe the status:

Removing Nodes
If for some reason we want to remove one of our nodes, we can do so using the remove command.
Suppose we wanted to remove the 5th service. First of all, we need to stop the service. Run the following command:
$ sudo safenode-manager stop --service-name safenode5
Observe that safenode5 has been stopped, but the others are still running:
$ safenode-manager status

Now that it's been stopped, remove it:
$ sudo safenode-manager remove --service-name safenode5
The status command will no longer show the service:

The node manager can be used to continually upgrade node services.
Suppose we have five services:

For brevity, the remaining output is snipped, but the four others are also at 0.104.38. At the time of writing, the latest version is 0.105.3.
We can use the upgrade command to get each service on the latest version:
$ sudo safenode-manager upgrade

Upgrade summary:
✓ safenode1 upgraded from 0.104.38 to 0.105.3
✓ safenode2 upgraded from 0.104.38 to 0.105.3
✓ safenode3 upgraded from 0.104.38 to 0.105.3
✓ safenode4 upgraded from 0.104.38 to 0.105.3
✓ safenode5 upgraded from 0.104.38 to 0.105.3
Again, for brevity some output from the command was snipped, but the summary indicates that each service was upgraded from 0.104.38 to 0.105.3.
As with other commands, if no arguments are supplied, upgrade operates over all services, but it's possible to use the --service-name or --peer-id arguments to upgrade specific services. Both those arguments can be used multiple times to operate over several services.
The node manager will determine the latest version of safenode, download it, then for each running service, if the service is older than the latest, it will stop it, copy the new binary over the old one, and start the service again.
Downgrading
In some situations, it may be necessary to downgrade safenode to a previous version. The upgrade command supports this by providing --version and --force arguments. Each of those can be used to force the node manager to accept a lower version.
Local Networks
Safenode Manager can also create local networks, which are useful for development or quick experimentation. In a local network, nodes will run as processes rather than services.
To create a local network, use the run command:
$ safenode-manager run

So by default, 25 node processes have been launched, along with a faucet. The faucet dispenses tokens for use when uploading files. We can now run safe commands against the local network.
The most common scenario for using a local network is for development, but you can also use it to exercise a lot of features locally. For more details, please see the 'Using a Local Network' section of the main README.
Once you've finished, run safenode-manager kill to dispose the local network.
