satellite6-upgrade's Introduction

Satellite6-upgrade

Satellite6 upgrade contains a set of tools that helps to perform various upgrade specific scenarios and moreover, it helps to validate data between pre and post upgrade to ensure data integrity after upgrade.

The major tasks of Satellite6 upgrade are:

  1. Create and delete satellite/capsule instances using RHEVM templates/Openstack images
  2. Upgrade Satellite6, Capsule instances spawn from RHEVM templates and clients generated through docker
  3. In case user has its own existing satellite/capsule and clients setup and wants to perform upgrade then Satellite6 upgrade has the capability to perform upgrade on user provided setups
  4. Performs data validation post upgrade to ensure the entities created before upgrade exists post upgrade as well

Supported Upgrade Paths are:

Product Major Version zStream
Satellite 6.1 -> 6.2 and 6.2-> 6.3 6.1 -> 6.1 and 6.2 -> 6.2
Capsule 6.1 -> 6.2 and 6.2-> 6.3 6.1 -> 6.1 and 6.2 -> 6.2
Clients 6.1 -> 6.2 and 6.2-> 6.3 6.1 -> 6.1 and 6.2 -> 6.2

Installation

Satellite6-Upgrade depends on pycurl being installed, but installing it, specially on a virtual environment is not straight forward. You must run the pycurl install script in order to have pycurl installed properly.

Finally, python packages listed in requirements.txt must be installed before satellite6-upgrade can be used:

pip install -r requirements.txt

Basic Usage Examples

Create Satellite/Capsule Instance from RHEVM template

To create a live satellite/capsule instance from RHEVM template: Pre-Conditions: The template should have a satellite/capsule populated in it already.

RHEV_USER=<user@domain> RHEV_PASSWD=<passwd> RHEV_URL='https://<rhev_url:port>/api'
fab create_rhevm_instance:<new_instance_name>,<template_name>,<datacenter>,<quota>,
<cluster>,<timeout_in_minutes>

Delete Satellite/Capule Instance from RHEVM template

To delete a satellite/capsule instance from RHEVM template: Pre-Condition - The instance should be already created

RHEV_USER=<user@domain> RHEV_PASSWD=<passwd> RHEV_URL='https://<rhev_url:port>/api'
fab delete_rhevm_instance:<new_instance_name>,<timeout_in_minutes>

Upgrade

Following are the upgrade type we support:

  1. Satellite
    • Upgrades only Satellite and NOT its capsule nor clients
  2. Capsule
    • Upgrades Capsule and its associated Satellite and NOT clients
  3. Clients
    • Upgrades Clients and its associated Satellite and NOT capsule
  4. Longrun
    • Upgrades Satellite, Capsules and clients

We would need different environment variables and fab commands depends on Upgrade Types.

As we look in usage examples above, the command is consisted of mainly two parts:

  1. Environment variables Again, environment variables required for each upgrade type has been divided into parts and its subparts, those are:
    • Common Environment Variables required for all types of upgrade
    • Environment Variables required for specific type of upgrade
      • Downstream Environment Variables
      • CDN Environment Variable
      • RHEVM Environment Variables
      • User Setup Environment Variables
  2. fab commands After Setting Environment Variables in Shell, We are good to run fab commands that will run upgrades on setup.

Environment Variables:

Common Environment Variables required for all types and combinations of upgrade

1. FROM_VERSION=<preSat_ver> TO_VERSION=<nextSat_ver> OS=<rhel6|rhel7>
2. Set FROM_VERSION and TO_VERSION to same current satellite version for Z-Stream Upgrade

Fab Commands for Setup and Upgrade Execution

These fab commands sets up the pre-requisites for upgrade and runs upgrade on satellite, capsule and clients.

Pre-Condition: - If RHEVM Setup, the ssh key of your machine should be added to the RHEVM images of satellite/capsule - If User setup, the ssh key of your machine should be added to user satellite, capsule and clients

NOTE: To run upgrade, one needs to run both setup and upgrade commands listed below.

SATELLITE UPGRADE

Satellite Upgrade will only upgrade Satellite, NOT Capsule and NOT Clients

Setup : fab setup_products_for_upgrade:satellite,<os: rhel6|rhel7>
Upgrade: fab product_upgrade:satellite
CAPSULE UPGRADE

Setup : fab setup_products_for_upgrade:capsule,<os: rhel6|rhel7>
Upgrade: fab product_upgrade:capsule
CLIENTS UPGRADE

Clients Upgrade will only upgrade Satellite and Clients, NOT Capsule

Setup : fab setup_products_for_upgrade:client,<os: rhel6|rhel7>
Upgrade: fab product_upgrade:client
LONGRUN UPGRADE

Longrun Upgrade will upgrade Satellite, Capsule and Clients

Setup : fab -u root setup_products_for_upgrade:longrun,<os: rhel6|rhel7>
fab product_upgrade:longrun

Post Upgrade Satellite Entity Verification

Satellite6-upgrade provides a facility to check if the entities before upgrade are existing/retained post upgrade.

Its very simple, We collect the data before upgrade and post upgrade from satellite and then we compare each entity. And display the results on stdout as well as XML file of reports will be generated, which further can be used.

This solely depends on pytest python package. So make sure that is installed.

To run the Satellite Post Upgrade Entity Verification, follow below steps :

  1. Set RUN_EXISTANCE_TESTS=true environment variable, with the environment variables for upgrade and before setup and upgrade fab commands.
  2. After Upgrade is Completed Successfully, for post upgrade entity verification results run following command : 
    py.test --junit-xml=reports.xml --continue-on-collection-errors upgrade_tests/test_existance_relations/

The results will be displayed on stdout and reports.xml file will be generate after all entities verification.
