//TODO OSDOCS-11789: Consider adding the following to a subsection about the initiating/control machine, along with CLI sections?
The machine that you run the installation process from must have access to the following:
2023-09-22 14:29:12 -04:00
* Amazon Web Services API and authentication service endpoints
* Red{nbsp}Hat OpenShift API and authentication service endpoints (`api.openshift.com` and `sso.redhat.com`)
* Internet connectivity to obtain installation artifacts during deployment
//TODO OSDOCS-13133 update when zero egress is GA: "either during deployment or prior to deploying a cluster with egress zero enabled"
2023-09-22 14:29:12 -04:00
//TODO OSDOCS-11789: This needs to be accessible from parts of the cluster, but not the deploying machine - omit entirely, or leave in place for Classic?

[IMPORTANT]
====
Starting with version 1.2.7 of the {rosa-cli-first}, all OIDC provider endpoint URLs on new clusters use Amazon CloudFront and the link:http://oidc.op1.openshiftapps.com/[oidc.op1.openshiftapps.com] domain. This change improves access speed, reduces latency, and improves resiliency for new clusters created with the {rosa-cli} 1.2.7 or later. There are no supported migration paths for existing OIDC provider configurations.
