Created a new Droplet

Before creating a Droplet let's first understand what is Digital Ocean and Droplet. DigitalOcean is a cloud hosting provider that offers cloud computing services and Infrastructure as a Service (IaaS). Droplets in DigitalOcean are Linux based Virtual Machines running on top of some hardware and each droplet you create a new server you can use.

Follow this blog on how to create a Droplet (server) in DigitalOcean

Conﬁgured Firewall

Conﬁgured Firewall rule to open port 22 for SSH access. Apply firewall on the droplet Networking > Firewall > Add Droplets
Now, copy the IP-Address of Droplet and Connect it via SSH
```
ssh root@<ip-address>
```

Installed Docker on Droplet

Install Docker on Droplet
```
snap install docker
```

Created docker volume for persistence nexus data

For persistence of data we need to config the docker volume for nexus. Otherwise we will lost our Nexus data if container stop or crash by some reason
```
docker volume create --name nexus-data
```
You can check if volume is create and it will spit out the name of volume
```
docker volume ls | grep nexus-data
```
local nexus-data

Run Nexus as Docker container with necessary parameters

docker run -d -p 8081:8081 --name nexus -v nexus-data:/nexus-data sonatype/nexus3

-d : detached, it will run the container in the background
-p 8081:8081 : it make this container accessible at port 8081 in your server (Droplet)
--name : container name
-v : volume (named volume here)
sonatype/nexus3 : Docker image name

Accessed Nexus in browser

Grab the IP Address of your Droplet and open your browser on that IP Address with port number 8081
```
http://IPaddress:8081
```
Change with your Droplet IP Address
If you see an interface like this on your browser then congratulation you have successfully deployed the nexus on your DigitalOcean droplet

Deploy Nexus as Docker Container on DigitalOcean Droplet
