How to restore droplet with R pulmber API running?

I have created a Rstudio droplet with a plumber API under the user ‘rtest’ at location ’/home/test/api.R’. I have taken a snapshot of this droplet. Now I am trying to restore the droplet using digital ocean API and run the command to start the plumber API. The following steps need to be done to run the API:

  1. Restore the droplet
  2. LogIn as “rtest” with credentials
  3. Change directory to “/home/rtest/
  4. Execute command "Rscript api.R”

How can I accomplish this? Or I need to do something else?

You could use the following request to generate your new Droplet:

curl -X POST -H 'Content-Type: application/json' \
    -H 'Authorization: Bearer $TOKEN' -d \
    '{"name":"","region":"nyc3","size":"512mb","image": 12345}' \

You need to change the details so that they match your requirements, and also you need to change the image ID with your snapshot ID as well.

In case that you need to get your image ID, you can do it with this request:

  • curl -X GET -H "Content-Type: application/json" -H "Authorization: Bearer $TOKEN" ""

For more information, you can take a look at the official documentation here:

In case that you wanted to run some specific commands, you could also pass user data to your API request like this:

curl -X POST "" \

apt-get -y update
apt-get -y install nginx
export HOSTNAME=$(curl -s
export PUBLIC_IPV4=$(curl -s
echo Droplet: $HOSTNAME, IP Address: $PUBLIC_IPV4 > /usr/share/nginx/html/index.html",
      "ssh_keys":[ < SSH KEY IDs > ]}' \
      -H "Authorization: Bearer $TOKEN" \
      -H "Content-Type: application/json"

For more information on user data you can take a look at the following documentation:
