This article describes how to bring up servers within Digital Ocean a cloud-based virtual private server (VPS) to host a server (Jenkins).

I want you to feel confident that you’ve mastered this skill. That’s why this takes a hands-on approach where you type in commands and we explain the responses and possible troubleshooting. This is a “deep dive” because all details are presented.

Like a good music DJ, I’ve carefully arranged the presentation of concepts into a sequence for easy learning, so you don’t have to spend as much time as me making sense of the flood of material around this subject.

Sentences that begin with PROTIP are a high point of this website to point out wisdom and advice from experience. NOTE point out observations that many miss. Search for them if you only want “TL;DR” (Too Long Didn’t Read) highlights.

Stuck? Contact me and I or one of my friends will help you.

Define SSH Keys
Open a Terminal shell window to a folder where you generate SSH key pair:

cd ~/.ssh

See https://www.digitalocean.com/community/tutorials/how-to-use-ssh-keys-with-digitalocean-droplets

ssh-keygen -t rsa
Save the file as “do_s” or another file of your choosing. Unlike other programs, we won’t be using the default file names on your machine.
Copy the public key file into your clipboard:

pbcopy < ~/.ssh/do_s.pub

Alternately, use a text editor to open the file to copy, such as:

atom ~/.ssh/id_rsa.pub
Switch back to the Create Droplet webpage to click “New SSH Key”.
Click in the box and press command+V to paste.

Server
Specify a server name.

PROTIP: Define (in writing) a server naming convention for use by your team. Use of sequential numbers would require a tracking system.
Select the location, etc.
Select Droplet image.

QUESTION: Select my own.
Copy the hostname to your clipboard and paste to your notes.

ubuntu-512mb-nyc1-01
Click the green Create button.
Copy the IP Address to your clipboard and paste to your notes. For example:

192.241.155.147
Click More to Access Console.

NOTE: Each Droplet spun up is a new VPS for your personal use.

Alternately,

ssh root@192.241.155.147

The first time you connect, you’ll see a message such as:
```
The authenticity of host '192.241.155.147 (192.241.155.147)' can't be established.
ECDSA key fingerprint is SHA256:sdfsdfsdfu5+Xsaf4COHb0UaRTxeoycUh4tLj1kwNQ.
Are you sure you want to continue connecting (yes/no)?
```
Type yes because this is expected behavior.
Enter your password.
Click API at the top menu.

Register the app.

Auto Deploy to Digital Ocean

We should then be able to trigger a manual deployment into production by supplying a valid RC release from the list of RC tagged releases.
