An earlier version of this tutorial was written by Brennen Bearnes.
Introduction
DigitalOcean’s web-based control panel provides a point-and-click interface for managing Droplets. However, you may prefer a command-line tool if you have many Droplets to manage, need to administer Droplets from the terminal without a graphical desktop available, or have tasks which would benefit from a scriptable interface.
doctl is the official DigitalOcean command-line client. It uses the DigitalOcean API to provide access to most account and Droplet features.
Prerequisites
To follow this tutorial, you will need:
A local computer with doctl installed by following the project’s installation and configuration instructions.
This tutorial is intended as a reference for most of doctl’s operations. Because doctl commands closely parallel the API, it may also be helpful to read the API documentation and How To Use the DigitalOcean API v2.
Generic doctl Usage
Invoking Commands
In doctl, individual features are invoked by giving the utility a command, one or more sub-commands, and sometimes one or more options specifying particular values. Commands are grouped under three main categories:
account for account-related information
auth for authenticating with DigitalOcean
compute for managing infrastructure
To see an overview of all commands, you can invoke doctl by itself. To see all available commands under one of the three main categories, you can use doctl category, like doctl compute. For a usage guide on a specific command, enter the command with the --help flag, as in doctl compute droplet --help.
Retrieving Data in JSON Format
In scripting environments, or when working on the command line with data-processing tools, it’s often helpful to get machine-readable output from a command.
By default, doctl formats its output in columns of human-readable text, but can produce detailed JSON output using the --output json option.
doctl compute droplet get droplet_id --output json
Sample {
"id": droplet_id,
"name": "droplet_name",
"memory": 1024,
"vcpus": 1,
"disk": 30,
"region": {
"slug": "nyc3",
"name": "New York 3",
"sizes": [
...
In addition to being a format readable with standard libraries in most programming languages, the JSON output may allow more fine-grained inspection of Droplets and other resources.
Formatting
It’s often useful to obtain only a set of fields from output. To do this, you can use the --format flag followed by a list of your desired fields. For example, if you want to obtain only the ID, name, and IP address of your Droplets, you can use the following command:
doctl compute droplet list --format "ID,Name,PublicIPv4"
Sample outputID Name Public IPv4
50513569 doctl-1 67.205.152.65
50513570 test 67.205.148.128
50513571 node-1 67.205.131.88
Templates
The doctl compute droplet get command supports output templating, which lets you customize the format of the output. To use this feature, specify the Go-formatted template via the --template flag.
For example, if you want to get a Droplet’s name in the format droplet_name: droplet_name, you would use the following get command:
doctl compute droplet get 12345678 --template "droplet_name: {{ .Name}}
droplet_name: ubuntu-1gb-nyc3-01
Working with Resources
Listing Resources
To get a list of resources, like Droplets, you can use the list command with no parameters.
doctl compute droplet list
Sample output for list commandID Name Public IPv4 Private IPv4 Public IPv6 Memory VCPUs Disk Region Image Status Tags
50513569 test-1 67.205.152.65 512 1 20 nyc1 Ubuntu 16.04.2 x64 active
50513571 test-2 67.205.131.88 512 1 20 nyc1 Ubuntu 16.04.2 x64 active
50513570 site 67.205.148.128 512 1 20 nyc1 Ubuntu 16.04.2 x64 active
The list command supports a glob as an optional parameter. A glob represents pattern with wildcard characters which can be used to filter specific resources by name. For example, to get a list of Droplets whose names start with test, you can use the following command:
doctl compute droplet list 'test*'
Sample output for list command with 'doctl-' as globID Name Public IPv4 Private IPv4 Public IPv6 Memory VCPUs Disk Region Image Status Tags
50513569 test-1 67.205.152.65 512 1 20 nyc1 Ubuntu 16.04.2 x64 active
50513571 test-2 67.205.131.88 512 1 20 nyc1 Ubuntu 16.04.2 x64 active
Creating Resources
Creating a resource requires longer commands with more detailed parameters. To create a Droplet, you’ll need to specify the image you want to use, the datacenter region, and the kind of Droplet you want by using its associated slug. See New Size Slugs for Droplet Plan Changes
to find the slug you want to use. Alternatively, run the doctl compute size list command.
For example, the following command creates a 64-bit Debian 8 Droplet named test with 1GB of memory, one CPU, an SSH key, and backups enabled.
doctl compute droplet create test --size s-1vcpu-1gb --image debian-8-x64 --region nyc1 --ssh-keys 4d:23:e6:e4:8c:17:d2:cf:89:47:36:b5:c7:33:40:4e --enable-backups
You’ll see this output:
Sample Droplet creation outputID Name Public IPv4 Memory VCPUs Disk Region Image Status
11450164 test 1024 1 30 nyc1 Debian 8.3 x64 new
Deleting a resource requires a resource ID as an argument, or a resource name in the event that an ID doesn’t exist for given resource (e.g. tags). To confirm your intentions, you need to confirm all delete actions by answering the confirmation question with y or yes.
doctl compute droplet delete 123456
Warning: Are you sure you want to delete droplet(s) (y/N) ?
Not providing an answer or providing an answer different from y or yes will cancel the action without deleting the resource. You can make doctl assume an affirmative answer without explicitly providing it, using --f (--force) flag:
doctl compute droplet delete -f 123456
Finding Unique Identifiers for Resources
The Droplet creation command requires a series of identifiers, like nyc1 for the NYC1 region, debian-8-x64 for the Debian image, and an SSH key fingerprint like 4d:23:e6:e4:8c:17:d2:cf:89:47:36:b5:c7:33:40:4e.
A number of resources, such as Droplets and images, are identified by a value (often numeric) unique within DigitalOcean’s database.
You can get the required unique identifiers for most commands from the API:
Command
Notes
doctl compute droplet list
Your Droplets. Some commands also take the name; most require the numeric value from the ID column.
doctl compute ssh-key list
The SSH keys associated with your account. For Droplet creation, you can specify either the numeric ID or fingerprint.
doctl compute region list
Available regions. Use the string in the Slug column.
doctl compute image list
Available images, including snapshots, backups, and base distribution images. Use the string in the Slug column for creating new Droplets.
doctl compute size list
Available Droplet sizes. Use the string in the Slug column.
doctl compute tag list
Available Tags. Use the string in the Name column.
Working with Droplets
Creating, Deleting, and Inspecting Droplets
The doctl compute droplet command lets you create, delete, and inspect Droplets. Again, most commands for working with individual Droplets require the Droplet’s unique ID, and these can be found in the output from doctl droplet list.
doctl compute droplet subcommand
Notes
actions droplet_id
Display a history of actions taken for a Droplet.
backups droplet_id
List backups for a Droplet.

snapshot droplet_id --snapshot-name snapshot_name
Take a snapshot of a Droplet, naming it snapshot_name.
Working with SSH
Making SSH Connections
In order to connect to an individual Droplet with SSH, it’s usually necessary to know either its IP address or fully-qualified domain name. You can instead use doctl to connect to a Droplet by its name, numeric ID or Private IP:
doctl compute ssh droplet_name
doctl compute ssh droplet_id
doctl compute ssh --ssh-private-ip droplet_private_ip
Also, you can provide a command to execute once the SSH connection is established using the --ssh-command flag. This will run the command, the output of which will be printed on your local terminal, and then the SSH session will close.
doctl compute ssh --ssh-command command
Note: SSH command forwarding is currently not available on Windows.
The default SSH user name is root (core for CoreOS) and the default port is 22. You can use flags to set non-default values and enable other features:
Flag
Description
--ssh-user string
User name to use for the SSH session.
--ssh-port int
The port for the SSH session.
--ssh-key-path string
Path to SSH key.
--ssh-agent-forwarding
Enable agent forwarding.
You can also change the default configuration values in a configuration file. The project’s README file has more detail on how to do this.

Working with Your Account
Reading History of Actions for Your Account
The DigitalOcean system logs a history of the actions taken on your Droplets, Floating IPs, and other resources. You can access this data with the doctl compute action command:
doctl compute action list
You can see actions for a specific Droplet like so:
doctl compute droplet actions droplet_id
Retrieving Your Account Information
You can discover basic details about your account, such as your configured e-mail address and Droplet limit:
doctl account get
Because API requests are rate-limited, it may be helpful to see how many requests you’ve made recently, and when the limit is due to reset:
doctl account ratelimit
Conclusion
The doctl utility is a helpful tool for managing Droplets and other resources at the command line. It can greatly reduce the amount of manual interaction with web-based interfaces needed for daily development and administrative tasks.
In addition to learning about the underlying API, you may want to explore libraries which wrap the API for popular programming languages, and tools such as Ansible for automating system-level tasks.
