+Jenkins Master
+==============
+
+Jenkins master as a head of CI systems handles all tasks related to the build
+system being responsible for its slaves connectivity, users authentication, and
+job launches.
+
+Deployment
+----------
+
+Before you deploy the Jenkins master, perform the following tasks:
+
+#. Verify that the Puppet Master is deployed and DNS solution is working.
+#. Consider using the Hiera role. As an example, see the ``jenkins_master`` role
+   included in the ``fuel-infra/puppet-manifests`` repository.
+#. Set the following parameters for the Hiera role on the Jenkins Master:
+
+   .. code-block:: ini
+
+     ---
+     classes:
+        - '::fuel_project::jenkins::master'

+
+#. Set proper service FQDN of the Jenkins Master instance:
+
+   .. code-block:: ini
+
+     fuel_project::jenkins::master::service_fqdn: 'jenkins-master.test.local'
+
+#. Adjust the security model of the Jenkins after the deployment:
+
+   .. code-block:: ini
+
+     jenkins::master::security_model: 'unsecured' || 'password' || 'ldap'
+
+   .. note::
+      The ``password`` is the most basic one, when Jenkins has no access to
+      the LDAP and you still require some authorization to be enabled in the
+      Jenkins.
+
+To deploy the Jenkins Master, complete the following steps:
+
+#. Install base Ubuntu 14.04 with SSH service and set appropriate FQDN.
+
+#. Install puppet agent package:
+
+   .. code-block:: console
+
+     apt-get update; apt-get install -y puppet
+
+#. Enable puppet agent:
+
+   .. code-block:: console
+
+     puppet agent --enable
+
+#. Run the Jenkins Master deployment:
+
+   .. code-block:: console
+
+     FACTER_ROLE=jenkins_master FACTER_LOCATION=us1 puppet agent -tvd \
+     --server puppet-master.test.local --waitforcert 60
+
+The last action requests the client's certificate. To continue the puppet run,
+the certificate should be signed from the Puppet Master.
