\"Easily<\/p>\n

<\/p>\n

We have already talked about Tarantool Cartridge<\/a><\/noindex>, which allows you to develop distributed applications and package them. There's just one more step: learning how to deploy these applications and manage them. Don't worry, we've got everything covered! We have gathered all the best practices for working with Tarantool Cartridge and written the ansible role<\/a><\/noindex>, which will unpack the package on the servers, start instances, cluster them, configure authorization, bootstrap vshard, enable automatic failover, and patch the cluster config.<\/p>\n

<\/p>\n

Interested? Then come on in, we will tell and show you everything.<\/p>\n

<\/a><\/noindex><\/p>\n

Let's start with an example<\/h1>\n

<\/p>\n

We will only consider a part of the functionality of our role. You can always find a complete description of all its capabilities and input parameters in the the documentation<\/a><\/noindex>. But it's better to try once than to see a hundred times, so let's deploy a small application.<\/p>\n

<\/p>\n

Tarantool Cartridge has a tutorial<\/a><\/noindex> for creating a small Cartridge application that stores information about bank customers and their accounts, as well as providing an API for managing data via HTTP. For this, the application describes two possible roles: api<\/code> and storage<\/code>, which can be assigned to instances.<\/p>\n

<\/p>\n

The Cartridge itself does not dictate how to run processes; it only provides the means to configure already running instances. The rest, the user must do on their own: unpack configuration files, start services, and set up the topology. But we won't be doing all that, Ansible will handle it for us.<\/p>\n

<\/p>\n

From words to action<\/h3>\n

<\/p>\n

So, let's deploy our application on two virtual machines and set up a simple topology:<\/p>\n
