Online installs that require a proxy to reach the public Internet can be configured with the
kurl section of the yaml spec.
apiVersion: cluster.kurl.sh/v1beta1 kind: Installer spec: kurl: proxyAddress: http://10.128.0.70:3128 additionalNoProxyAddresses: - .corporate.internal noProxy: false
The proxy configuration will be used to download packages required for the installation script to complete and will be applied to the docker and KOTS add-ons. See Modifying an Install Using a YAML Patch File for more details on using patch files.
proxyAddress is not configured in the installer spec, the following environment variables will be checked in order:
Any addresses set in either the
no_proxy environment variable will be added to the list of no proxy addresses.
All addresses set in the
additionalNoProxyAddresses list will be added to the default set of no proxy addresses.
Addresses can be specified as a single IP address or a range of addresses in CIDR notation.
The default set of no proxy addresses includes:
.localsearch domains for cluster services
Addresses of all hosts in the cluster must be to included in the
additionalNoProxyAddresses parameter in advance of installing or joining additional nodes.
This parameter can be set using a YAML patch file or passed into the install script using the
When a host is added to the cluster, if the original list of addresses did not encompass this host's address, the install or upgrade script must be re-run on each host with the new host added to the
For this reason it is recommended to use a range of addresses in CIDR notation to prevent the need for retroactively running the installer when adding additonal nodes.
