## Create your server
Co-op Cloud has itself near zero system requirements. You only need to worry about the system resource usage of your apps and the overhead of running containers with the docker runtime (often negligible. If you want to know more, see [this FAQ entry](/faq/#isnt-running-everything-in-container-really-inefficient)). We will deploy a new Nextcloud instance in this guide, so you will only need 1GB of RAM according to [their documentation](https://docs.nextcloud.com/server/latest/admin_manual/installation/system_requirements.html).

## Wire up your DNS

On your server, you'll want to install [Docker](https://www.docker.com/). This can be done by following the [install documentation](https://docs.docker.com/engine/install/).
On a Debian system, that can be done like so.
```bash
$ sudo apt-get remove docker docker-engine docker.io containerd runc
$ sudo apt update
$ sudo apt-get install -y apt-transport-https ca-certificates curl gnupg-agent software-properties-common
$ curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"
$ sudo apt-get update
$ sudo apt-get install -y docker-ce docker-ce-cli containerd.io
```
## Bootstrap abra
Once your DNS and docker daemon are up, you can install [abra](https://git.autonomic.zone/autonomic-cooperative/abra) locally on your developer machine and hook it up to your server.

Where `example.com` is replaced with your identifier for your server DNS.
`abra server add` accepts also a `<user>` and `<port>` argument for your custom SSH connection details. What is happening here is that you are using the underlying SSH connection to make a secure connection to the server installed Docker daemon. This allows `abra` to run remote deployments from your local development machine.

What is happening here is that you are using the underlying SSH machinery to make a secure connection to the server installed Docker daemon. This allows `abra` to run remote deployments from your local development machine.
Once you've added the sever, you can initialise the new single-host swarm.
```bash
$ abra server init example.com
$ abra server example.com init
```
You will now have a new `~/.abra/` folder on your local file system which stores all the configuration of your Co-op Cloud instance. You can easily share this as a git repository with others.

```bash
$ abra app new --server example.com --domain traefik.example.com traefik
$ abra app traefik.autonomic.zone deploy
```
You will want to take a look at your generated configuration and tweak the `LETS_ENCRYPT_EMAIL` value:
```bash
$ abra app traefik.example.zone config
```
This is the required environment variables that you can configure and are injected into the app configuration when deployed.
```
$ abra app traefik.example.zone deploy
```
We can then check that everything came up as expected.
```bash
$ abra app traefik.example.zone ps # status check
$ abra app traefik.example.zone logs # logs watch
```
## Deploy Nextcloud
And now we can deploy apps. Go ahead and create a new nextcloud app, generate secrets and deploy it.
And now we can deploy apps.
Let's create a new Nextcloud app.
```bash
$ abra app new --server example.com --domain cloud.example.com nextcloud
$ abra app cloud.example.com secret generate --all
$ abra app cloud.autonomic.zone deploy
```
And we need to generate secrets for the app: database connection password, root password and admin password.
```bash
$ abra app cloud.example.com secret generate --all
```
Take care, these secrets are only shown once on the terminal so make sure to take note of them! Abra makes use of the [Docker secrets](https://docs.docker.com/engine/swarm/secrets/) mechanism to ship these secrets securely to the server and store them as encrypted data.
Then we can deploy the Nextcloud.
```bash
$ abra app cloud.example.zone deploy
```
And once again, we can watch to see that things come up correctly.
```bash
$ abra app nextcloud.example.zone ps # status check
$ abra app nextcloud.example.zone logs # logs watch
```
!!! note
Since Nextcloud takes some time to come up live, you can run the `ps` command under `watch` like so.
```bash
$ watch abra app nextcloud.example.zone ps
```
And you can wait until you see that all containers have the "Running" state.
Your Traefik instance should now detect that a new app is coming up and generate SSL certificates for it.
