# exoscale-instance-type
A parameter with all Exoscale instance types. This allows developers to select
their desired virtuell machine for the workspace.
Customize the preselected parameter value:
```hcl
module "exoscale-instance-type" {
source = "https://registry.coder.com/modules/exoscale-instance-type"
default = "standard.medium"
}
resource "exoscale_compute_instance" "instance" {
type = module.exoscale-instance-type.value
...
}
resource "coder_metadata" "workspace_info" {
item {
key = "instance type"
value = module.exoscale-instance-type.name
}
}
```
![Exoscale instance types](../.images/exoscale-instance-types.png)
## Examples
### Customize type
Change the display name a type using the corresponding maps:
```hcl
module "exoscale-instance-type" {
source = "https://registry.coder.com/modules/exoscale-instance-type"
default = "standard.medium"
custom_names = {
"standard.medium": "Mittlere Instanz" # German translation
}
custom_descriptions = {
"standard.medium": "4 GB Arbeitsspeicher, 2 Kerne, 10 - 400 GB Festplatte" # German translation
}
}
resource "exoscale_compute_instance" "instance" {
type = module.exoscale-instance-type.value
...
}
resource "coder_metadata" "workspace_info" {
item {
key = "instance type"
value = module.exoscale-instance-type.name
}
}
```

### Use category and exlude type
Show only gpu1 types
```hcl
module "exoscale-instance-type" {
source = "https://registry.coder.com/modules/exoscale-instance-type"
default = "gpu.large"
type_category = ["gpu"]
exclude = [
"gpu2.small",
"gpu2.medium",
"gpu2.large",
"gpu2.huge",
"gpu3.small",
"gpu3.medium",
"gpu3.large",
"gpu3.huge"
]
}
resource "exoscale_compute_instance" "instance" {
type = module.exoscale-instance-type.value
...
}
resource "coder_metadata" "workspace_info" {
item {
key = "instance type"
value = module.exoscale-instance-type.name
}
}
```
