--- title: Define Proxy Settings slug: install-10x/define-proxy-settings docTags: createdAt: 2025-07-16T13:29:40.590Z --- If your environment requires a proxy server, you can add proxy settings (under the kurl spec) to the installer-override.yaml patch file `spec:` section. For example: :::BlockQuote apiVersion: cluster.kurl.sh/v1beta1 kind: Installer metadata: name: "patch" spec: kurl: proxyAddress: "http\://\:\" additionalNoProxyAddresses: \- .corporate.internal \- .other.domains ::: - Set `proxyAddress:` to the address and port of the proxy server. - Set `additionalNoProxyAddresses:` to a yaml list of IP CIDR ranges or domains that should not be proxied. - You must add the private IPs of every cluster node - Swimlane recommends specifying an IP range in CIDR notation to encompass future node IPs in order to prevent re-running the install command when addition nodes are added to the cluster. - All addresses specified here will be added to the default set of no-proxy addresses. The default set includes: - The CIDR used for assigning IPs to Kubernetes services - The CIDR used for assigning IPs to pods - The private IP of the host where the script runs - The load balancer address for the Kubernetes API servers (on HA installs) - The .svc and .local search domains for cluster services - Add-on namespaces - Other service hostnames referenced by add-ons without fully qualified domain names :::hint{type="danger"} Prior to installing or joining additional nodes, include the address of all nodes in the cluster in the `additionalNoProxyAddresses` parameter. If you do not include the addresses of all the nodes, then you will have to re-run the install command on *every other node* along with the new node IP address added to the additionalNoProxyAddresses parameter. Because of this, Swimlane recommends that you use a range of addresses, in CIDR notation, during the initial install and join commands instead of individual node IPs. ::: See [Overriding Installer Settings](docId\:X7jKIJjG4IP6y3FqQqxyI) for instructions on how to specify the installer override file during the install and join node commands.
