body: <p>I'm use these how to install the FreeIPA with Docker (centos7) [<a href="https://hub.docker.com/r/freeipa/freeipa-server/" rel="nofollow noreferrer">https://hub.docker.com/r/freeipa/freeipa-server/</a> ] and I do not see any errors after these command: </p>
  
  <p>`</p>
  
  <pre><code>docker run --name freeipa-server-container -ti -h ipa.labs.net -v /sys/fs/cgroup:/sys/fs/cgroup:ro --sysctl net.ipv6.conf.all.disable_ipv6=0 --cap-add=SYS_ADMIN --tmpfs /run --tmpfs /tmp -v /var/lib/ipa-data/ipa:/data:Z freeipa-server:centos7 exit-on-finished --no-ntp

  The ipa-client-install command was successful

  Setup complete
  
  Next steps:
          1. You must make sure these network ports are open:
                  TCP Ports:
                    * 80, 443: HTTP/HTTPS
                    * 389, 636: LDAP/LDAPS
                    * 88, 464: kerberos
                  UDP Ports:
                    * 88, 464: kerberos
  
          2. You can now obtain a kerberos ticket using the command: 'kinit admin'
             This ticket will allow you to use the IPA tools (e.g., ipa user-add)
             and the web user interface.
          3. Kerberos requires time synchronization between clients
             and servers for correct operation. You should consider enabling ntpd.
  
  Be sure to back up the CA certificates stored in /root/cacert.p12
  These files are required to create replicas. The password for these
  files is the Directory Manager password
  FreeIPA server does not run DNS server, skipping update-self-ip-address.
  Created symlink from /etc/systemd/system/container-ipa.target.wants/ipa-server-update-self-ip-address.service to /usr/lib/systemd/system/ipa-server-update-self-ip-address.service.
  Created symlink from /etc/systemd/system/container-ipa.target.wants/ipa-server-upgrade.service to /usr/lib/systemd/system/ipa-server-upgrade.service.
  Removed symlink /etc/systemd/system/container-ipa.target.wants/ipa-server-configure-first.service.
  FreeIPA server configured.
