We are bringing the best of Tectonic to Red Hat OpenShift to build the most secure, hybrid Kubernetes application platform.
This document gives an overview of variables used in all platforms of the Tectonic SDK.
Name | Description | Type | Default |
---|---|---|---|
tectonic_admin_email | (internal) The e-mail address used to: 1. login as the admin user to the Tectonic Console. 2. generate DNS zones for some providers. Note: This field MUST be in all lower-case e-mail address format and set manually prior to creating the cluster. |
string | - |

tectonic_base_domain | The base DNS domain of the cluster. It must NOT contain a trailing period. Some DNS providers will automatically add this if necessary. Example: openstack.dev.coreos.systems .Note: This field MUST be set manually prior to creating the cluster. This applies only to cloud platforms. [Azure-specific NOTE] To use Azure-provided DNS, tectonic_base_domain should be set to "" If using DNS records, ensure that tectonic_base_domain is set to a properly configured external DNS zone. Instructions for configuring delegated domains for Azure DNS can be found here: https://docs.microsoft.com/en-us/azure/dns/dns-delegate-domain-azure-dns |

string | `` |
tectonic_etcd_ca_cert_path | (optional) The path of the file containing the CA certificate for TLS communication with etcd. Note: This works only when used in conjunction with an external etcd cluster. If set, the variable tectonic_etcd_servers must also be set. |
string | /dev/null |
tectonic_etcd_client_cert_path | (optional) The path of the file containing the client certificate for TLS communication with etcd. Note: This works only when used in conjunction with an external etcd cluster. If set, the variables tectonic_etcd_servers , tectonic_etcd_ca_cert_path , and tectonic_etcd_client_key_path must also be set. |
string | /dev/null |
tectonic_etcd_client_key_path | (optional) The path of the file containing the client key for TLS communication with etcd. Note: This works only when used in conjunction with an external etcd cluster. If set, the variables tectonic_etcd_servers , tectonic_etcd_ca_cert_path , and tectonic_etcd_client_cert_path must also be set. |
string | /dev/null |
tectonic_etcd_count | The number of etcd nodes to be created. If set to zero, the count of etcd nodes will be determined automatically. Note: This is not supported on bare metal. |
string | 0 |
tectonic_etcd_servers | (optional) List of external etcd v3 servers to connect with (hostnames/IPs only). Needs to be set if using an external etcd cluster. Note: If this variable is defined, the installer will not create self-signed certs. To provide a CA certificate to trust the etcd servers, set "tectonic_etcd_ca_cert_path". Example: ["etcd1", "etcd2", "etcd3"] |
list | <list> |
tectonic_etcd_tls_enabled | (optional) If set to true , all etcd endpoints will be configured to use the "https" scheme.Note: If tectonic_experimental is set to true this variable has no effect, because the experimental self-hosted etcd always uses TLS. |
