Дополнительные инструкции

Please provide a link to at least one of the following challenges together with your application. It can be a URL, Git repository or a Github Pull Request depending on the challenge. You can send your application as soon as you sent your Pull Request or git repository and then continue interacting with the developers while your application is reviewed. Challenge #1 Install Spacewalk nightly (http://www.spacewalkproject.org/) with PostgreSQL backend on a Virtual Machine Checkout this simple project: https://github.com/SUSE/spacewalk-osad2 Look at the README and understand what it does. Implement a missing feature, code improvement or open issue and create a Pull Request. Discuss with the developer that looked at your Pull Request. Challenge #2 Install Spacewalk nightly (http://www.spacewalkproject.org/) with PostgreSQL backend on a Virtual Machine Configure any kind of High Availability replication for the PostgreSQL RDBMS, making sure the correct server is used in case of failover at least for the Java portion of the Web UI, or propose a configuration based on a pooling server (pgpool, pgbouncer…); Document the steps needed to implement the above together with a discussion over advantages and disadvantages of the chosen approach. Ideally, use vagrant (https://www.vagrantup.com/) and/or SaltStack (http://saltstack.com/). Challenge #3 Install Saltstack (http://www.saltstack.com) on a pair of virtual machines and create a master/minion configuration. Ideally, use Vagrant for automating the setup (https://www.vagrantup.com/). Understand how Saltstack works and the concepts of modules, states, beacons, etc. Implement a new execution/state, beacon, or authentication module of your choice. Point us to the source code.
