Chapter 2. Ceph Dashboard installation and access As a system administrator, you can access the dashboard with the credentials provided on bootstrapping the cluster. Cephadm installs the dashboard by default. Following is an example of the dashboard URL: Note Update the browser and clear the cookies prior to accessing the dashboard URL. The following are the Cephadm bootstrap options that are available for the Ceph dashboard configurations: [-initial-dashboard-user INITIAL_DASHBOARD_USER ] - Use this option while bootstrapping to set initial-dashboard-user. [-initial-dashboard-password INITIAL_DASHBOARD_PASSWORD ] - Use this option while bootstrapping to set initial-dashboard-password. [-ssl-dashboard-port SSL_DASHBOARD_PORT ] - Use this option while bootstrapping to set custom dashboard port other than default 8443. [-dashboard-key DASHBOARD_KEY ] - Use this option while bootstrapping to set Custom key for SSL. [-dashboard-crt DASHBOARD_CRT ] - Use this option while bootstrapping to set Custom certificate for SSL. [-skip-dashboard] - Use this option while bootstrapping to deploy Ceph without dashboard. [-dashboard-password-noupdate] - Use this option while bootstrapping if you used above two options and don't want to reset password at the first time login. [-allow-fqdn-hostname] - Use this option while bootstrapping to allow hostname that is fully-qualified. [-skip-prepare-host] - Use this option while bootstrapping to skip preparing the host. Note To avoid connectivity issues with dashboard related external URL, use the fully qualified domain names (FQDN) for hostnames, for example, host01.ceph.redhat.com . Note Open the Grafana URL directly in the client internet browser and accept the security exception to see the graphs on the Ceph dashboard. Reload the browser to view the changes. Example Note While boostrapping the storage cluster using cephadm , you can use the --image option for either custom container images or local container images. Note You have to change the password the first time you log into the dashboard with the credentials provided on bootstrapping only if --dashboard-password-noupdate option is not used while bootstrapping. You can find the Ceph dashboard credentials in the var/log/ceph/cephadm.log file. Search with the "Ceph Dashboard is now available at" string.
