The easiest and cheapest path is to use the one-click application in the DigitalOcean marketplace.

After deploying, log into your new DigitalOcean Droplet as root using the password you provided when creating a “Droplet” (virtual machine) with Lotus pre-installed:

ssh root@<your_droplet_public_ipv4>

Using the DigitalOcean API to deploy Lotus

You can also spin up Lotus nodes programmatically. For example, to create a 4 GB filecoin-lotus Droplet in the SFO2 region, you can use the following curl command:

curl -X POST -H 'Content-Type: application/json' \
-H 'Authorization: Bearer '$TOKEN'' \
-d '{"name":"a_name","region":"sfo2","size":"s-2vcpu-4gb",
"image":"protocollabs-filecoinlotus-20-04"}'  ""

Amazon Web Services

We regularly publish AMIs for each of the filecoin networks. To use one of these images, just search for one of our AMIs. You can use this example link which populates a search for Lotus in the us-west-2 region.

After you launch your AWS instance, you should log in with the ‘ubuntu’ account. The filecoin instance runs a host-based firewall (UFW) which blocks all incomming ports except for port 22 and 5678 (libp2p). This works well if you want to place your instance behind a permissive security group.

ssh ubuntu@<your_instance_public_ipv4>

Using the Instance

As soon as the instance is started, it will download a large file containing the last 2000 state roots. During this time the lotus API will not be up, but lotus is working. After about 20 minutes, the state root download will complete and lotus will start normally. This process happens automatically. You don’t need to do anything for lotus to start.

If you’re interested in seeing what’s going on, you can view lotus’s logs in the systemd journal.

journalctl -u lotus-daemon

While the stateroot file is downloading, systemctl will show the status of this job as “Activating”.

You will notice that the job has not started yet. Don’t worry, it will transition into an active state after the stateroot file is imported.

[mainnet ~] ⨎ systemctl status lotus-daemon

After about 20 minutes, the stateroot snapshot will have completed its download and lotus will start normally.

Now that the stateroot has been downloaded successfully, you can interact with the lotus network.
