To learn more about common\nroles and example tasks that we reference in Google Cloud content, see\n[Common GKE user roles and tasks](/kubernetes-engine/enterprise/docs/concepts/roles-tasks).\n\nIn certain situations you must enter an IP address, and in other situations you\nmust enter a hostname. And in some cases, it doesn't matter. You can determine\nthe appropriate value by inspecting the serving certificate of your vCenter\nserver.\n\nDownload the serving certificate of your vCenter server, and save it to a file\nnamed `vcenter.pem`:\n\n```\ntrue | openssl s_client -connect VCENTER_IP:443 -showcerts 2\u003e/dev/null | sed -ne '/-BEGIN/,/-END/p' \u003e vcenter.pem\n```\n\nReplace \u003cvar translate=\"no\"\u003eVCENTER_IP\u003c/var\u003e with the IP address of your\nvCenter Server.\n\nOpen the certificate file to see the Subject Common Name and the Subject\nAlternative Name:\n\n```\nopenssl x509 -in vcenter.pem -text -noout\n```\n\nThe output shows the Subject Common Name (CN). This might be an IP address, or\nit might be a hostname. For example:\n\n```\nSubject: ... CN = 203.0.113.100\n```\n\n```\nSubject: ... CN = my-host.my-domain.example\n```\n\nThe output might also include one or more DNS names under\n`Subject Alternative Name`:\n\n```\nX509v3 Subject Alternative Name:\n DNS:vcenter.my-domain.example\n```\n\nChoose the Subject Common Name or one of the DNS names under\n`Subject Alternative Name` to use as the value of the vCenter server address\nin your configuration file. For example:\n\n```\nvCenter:\n credentials:\n address: \"203.0.113.1\"\n```\n\n```\nvCenter:\n credentials:\n address: \"my-host.my-domain.example\"\n```"]]
