# Quick Start

Write a short introduction and the getting started guide to your product. 
If there are any standout features to call it, this is probably the place to do it. 

NOTE: Take a look at the quick-start of Object Storage (community/community/content/product/storage/object-storage/quick-start/_index.md) for an idea on the tone and the level of detail.

## Creating an Elastic IP
You can create an Elastic IP through the [Portal](https://portal.exoscale.com/), the [CLI](https://github.com/exoscale/cli) or
the [API](https://community.exoscale.com/reference/api/compute/elastic-ip/#list-elastic-ips).


This is an example from the CLI:

__`exo compute elastic-ip create ...`__

Create a manual Elastic IP:

```bash
exo compute elastic-ip create --zone de-fra-1
```

Output:

```bash
 ✔ Creating Elastic IP... 3s
┼─────────────┼──────────────────────────────────────┼

│ ID          │ 5a5aed48-7a46-442a-8456-0a15d931fd0b │
│ IP Address  │ 203.0.113.202                        │
│ Description │                                      │
│ Zone        │ de-fra-1                             │
│ Type        │ manual                               │
┼─────────────┼──────────────────────────────────────┼
```

Create a managed Elastic IP:

```bash
exo compute elastic-ip create  \
  --zone de-fra-1                \
  --healthcheck-interval 60      \
  --healthcheck-mode tcp         \
  --healthcheck-port 80          \
  --healthcheck-strikes-fail 5   \
  --healthcheck-strikes-ok 5     \
  --healthcheck-timeout 10
```

Output:

```bash
 ✔ Creating Elastic IP... 3s
┼──────────────────────────┼──────────────────────────────────────┼
│        ELASTIC IP        │                                      │

│ ID                       │ 868d029d-b1a2-4fd3-9006-4b98998240b4 │

│ Zone                     │ de-fra-1                             │
│ Type                     │ managed                              │
│ Healthcheck Mode         │ tcp                                  │
│ Healthcheck Port         │ 80                                   │
│ Healthcheck Interval     │ 1m0s                                 │
│ Healthcheck Timeout      │ 10s                                  │
│ Healthcheck Strikes OK   │ 5                                    │
│ Healthcheck Strikes Fail │ 5                                    │
┼──────────────────────────┼──────────────────────────────────────┼
```

Note that in order to create a managed Elastic IP, you have to provide health
check parameters. Without those parameters, the Elastic IP is created as manual
management type.

## Attaching an Elastic IP
Once the Elastic IP address as been created, you can attach it to one or more
Compute instances. Here is another example from the CLI:

__`exo compute instance elastic-ip attach ...`__

```bash
exo compute instance elastic-ip attach my-instance 203.0.113.202
```

Output:

```bash
 ✔ Attaching Elastic IP "203.0.113.202" to instance "my-instance"... 3s

The Elastic IP is now routing traffic to `my-instance`.

After an Elastic IP is attached to an instance, a managed Elastic IP does not
require explicitly configuring an extra network interface on the instance.
However, a manual Elastic IP requires some
[further configuration](/product/networking/eip/how-to#configure-a-manual-elastic-ip-on-an-instance).
