+# Ingress, domains and proxies
+
+## Default configurations for domain and subdomains
+Cloud Harness makes it very easy to configure domains and proxies, by making
+an underlying assumption:
+
+- Applications share a main base domain (say ch.org)
+- Applications can define a subdomain (say myapp)
+
+The main domain is configured in the [root values file](../deployment-configuration/values-template.yaml) and
+it is usually overridden by the `harness-deployment` command, e.g.
+
+```
+harness-deployment ... -d ch.org
+```
+
+The subdomain is defined in the application's values.yaml file in 
+harness.subdomain (see for instance the [samples application configuration](../applications/samples/deploy/values.yaml))
+
+For instance on applications/myapp/deploy/values.yaml:
+
+```yaml
+harness:
+  subdomain: myapp
+```
+
+The above configurations put together create an ingress configuration for https://myapp.ch.org and automatically configure letsencrypt to create and renew certificates.
+
+Note:
+that the tls and letsencrypt configurations are enabled by default but should usually be disabled locally with
+
+```
+harness-deployment ... -dtls -l
+```
+
+## Main application
+
+The "main" application is deployed on the base domain.
+In order to specify a main application, override the value in your `/deployment-configuration/values-template.yaml` file.
+
+Example
+```yaml
+mainapp: myapp
+```
+This creates a reverse proxy to https://ch.org pointing to myapp
+
+## Proxy configurations
+
+Ingress is a reverse proxy and as such has some configurations to take into account.
+The most common configurations are connection timeouts and payload size.
+
+To configure it, override the following values in your `deployment-configuration/values-template.yaml` file.
+
+```yaml
+proxy:
+  timeout:
+    # -- Timeout for proxy connections in seconds.
+    send: 60
+    # -- Timeout for proxy responses in seconds.
+    read: 60
+    keepalive: 60
+  payload:
+    # -- Maximum size of payload in MB
+    max: 250
+```
+
+Note that in the case that gatekeepers are enabled, the same configurations are applied
+to the gatekeepers, unless the application override them on `harness.proxy.*`.
+See also the [gatekeepers documentation](./accounts.md#secure-and-enpoint-with-the-gatekeeper).
