+# exoscale-zone
+
+A parameter with all Exoscale zones. This allows developers to select
+the zone closest to them.
+
+Customize the preselected parameter value:
+
+```hcl
+module "exoscale-zone" {
+    source = "https://registry.coder.com/modules/exoscale-zone"
+    default = "ch-dk-2"
+}
+
+
+data "exoscale_compute_template" "my_template" {
+  zone = module.exoscale-zone.value
+  name = "Linux Ubuntu 22.04 LTS 64-bit"
+}
+
+resource "exoscale_compute_instance" "instance" {
+  zone    = module.exoscale-zone.value
+  ....
+}
+```
+
+![Exoscale Zones](../.images/exoscale-zones.png)
+
+## Examples
+
+### Customize zones
+
+Change the display name and icon for a zone using the corresponding maps:
+
+```hcl
+module "exoscale-zone" {
+    source = "https://registry.coder.com/modules/exoscale-zone"
+    default = "at-vie-1"
+    custom_names = {
+        "at-vie-1": "Home Vienna"
+    }
+    custom_icons = {
+        "at-vie-1": "/emojis/1f3e0.png"
+    }
+}
+
+data "exoscale_compute_template" "my_template" {
+  zone = module.exoscale-zone.value
+  name = "Linux Ubuntu 22.04 LTS 64-bit"
+}
+
+resource "exoscale_compute_instance" "instance" {
+  zone    = module.exoscale-zone.value
+  ....
+}
+```
+
+![Exoscale Custom](../.images/exoscale-custom.png)
+
+### Exclude regions
+
+Hide the Switzerland zones Geneva and Zurich
+
+```hcl
+module "exoscale-zone" {
+    source = "https://registry.coder.com/modules/exoscale-zone"
+    exclude = [ "ch-gva-2", "ch-dk-2" ]
+}
+
+data "exoscale_compute_template" "my_template" {
+  zone = module.exoscale-zone.value
+  name = "Linux Ubuntu 22.04 LTS 64-bit"
+}
+
