Software Included

Creating an App using the Control Panel

Click the Deploy to DigitalOcean button to create a Droplet based on this 1-Click App. If you aren’t logged in, this link will prompt you to log in with your DigitalOcean account.

Creating an App using the API

In addition to creating a Droplet from the IceWarp 1-Click App using the control panel, you can also use the DigitalOcean API. As an example, to create a 4GB IceWarp Droplet in the SFO2 region, you can use the following curl command. You need to either save your API access token to an environment variable or substitute it in the command below.

curl -X POST -H 'Content-Type: application/json' \
         -H 'Authorization: Bearer '$TOKEN'' -d \
        '{"name":"choose_a_name","region":"sfo2","size":"s-2vcpu-4gb","image":"icewarp"}' \
        "https://api.digitalocean.com/v2/droplets"

Getting Started After Deploying IceWarp

Getting started

Step 1: Deploy your Droplet

Launch the IceWarp 1-Click App from the DigitalOcean Marketplace. Once your Droplet is created, give it a few minutes—IceWarp runs post-deployment configuration in the background to set everything up for you. You can connect to your Droplet via SSH to see the status.

Step 2: Check configuration status

SSH into your Droplet:

ssh root@your_droplet_public_ipv4

You’ll see a message indicating that configuration is in progress:

--- Your IceWarp instance is being configured. Please wait, this message will change when it's done.

This typically takes 2–3 minutes. Grab a coffee.

Step 3: Access your IceWarp instance

Once configuration completes, you’ll see:

--- Log into your IceWarp using admin@<domain>.do.tryicewarp.com on https://<domain>.do.tryicewarp.com! Password is stored in /tmp/iw_password.

Retrieve your admin password through the shell:

cat /tmp/iw_password

Open your browser and navigate to the URL shown in the message, or access IceWarp directly at https://your_droplet_public_ipv4. Log in with your admin credentials and start exploring.

Step 4: Connect your own domain (optional)

Your Droplet comes with a temporary *.do.tryicewarp.com domain so you can start immediately. When you’re ready to use your own domain, configure it through the IceWarp admin console and update your external DNS records (MX, SPF, DKIM, DMARC) to point to your Droplet.
