+=======================
+ Salt formula backports
+=======================
+------------
+ Readme file
+------------
+
+Setting up downstream mirror
+============================
+
+Setup formula syncronisation after you deployed Drivertain. The backport state can be used to apply any patches/modification which hadn't been included to offical packages. The state uses the backports:patches pillar to keep the neccessary information.
+
+Step 1:
+Check jenkins_admin_public_key and add it to service user in gerrit(git repo).
+
+Got to https://gerrit.mirantis.com/login/
+Login as "service" user.
+Navigate to Setting -> SSH Public Keys.
+Add new key.
+
+Step 2:
+
+Add following pillar to cicd leader::
+
+  parameters:
+    _param:
+      jenkins_git_mirror_downstream_jobs:
+        - name: salt-formula-backports
+          downstream: formulas/salt-formula-backports
+          upstream: "ssh://robot@gerrit.example.com:29418/formulas/salt-formula-backports"
+          branches: master
+    gerrit:
+      client:
+        project:
+          formulas/salt-formula-backports:
+            enabled: true
+            description: Backport formula
+            upstream: "ssh://robot@gerrit.example.com:29418/formulas/salt-formula-backports"
+            access: ${gerrit:client:default_access}
+            require_change_id: true
+            require_agreement: false
+            merge_content: true
+
+Step 3:
+Run the highstate on cid01 node::
+
+  salt "cid01*" state.highstate
+
+Setting up downstream mirror
+============================
+
+This this is how you can setup automated formula installation on salt master from local gerrit.
+Step 1:
+Add following pillar to config::
+
+  root@cfg01:/srv/salt/reclass# cat  ./classes/cluster/mlab/infra/backports/formula.yml
+  parameters:
+    _param:
+      local_salt_formulas: http://${_param:cicd_control_address}:8080/formulas
+      local_salt_formulas_revision: master
+    salt:
+      master:
+        environment:
+          prd:
+            formula:
+              backports:
+                source: git
+                address: '${_param:local_salt_formulas}/salt-formula-backports'
+                revision: ${_param:local_salt_formulas_revision}
+
+
+Step 2:
+
+Run the highstate on cfg01 node::
+
+  salt 'cfg01*' state.highstate
+
+How to enable specific patch
+============================
+For example to enable patch on salt master's ntp formula
+
+Add following class or define the  pillar on the salt master (make sure pillar is visible only for this particular node)::
+
+  root@cfg01:/srv/salt/reclass# cat  ./classes/cluster/lab/infra/config/patches.yml
+  applications:
+    - backports
+
+  parameters:
+    backports:
+      patches:
+        compute_patch:    												# you can refer to jira issue, gerrit CR, salesforce ID or any other id.
+          /etc/init/nova-compute-kvm-upstart.conf:       								# file to apply the patch
+            md5sum: 34dd520613bda0bf572a3bcee5767d29									# md5sum of resulted file

+How to create a new patch
+=========================
+
+Back original file::

+
+Make the necessary  change::
+
+  vim  /etc/init/nova-compute-kvm-upstart.conf

+
+
+Best practice:
+==============
+
+1. Make sure product bug/ticket/review is created to resolve the problem in upstream.
+2. Add a link to the product ticket/review next to the resource in the formula.
+3. Make sure to add service restart if needed.
+4. Pay attention to failed patch resources. Most likely this means that file was changed.  review the file and update or disable the patch if necessary.
