Nautobot v1.1

This document describes all new features and changes in Nautobot 1.1.

If you are a user migrating from NetBox to Nautobot, please refer to the "Migrating from NetBox" documentation.

Release Overview

Added

Computed Fields (#4)

Computed fields offers users the ability to create read-only custom fields using existing data already stored in the database. Users define Jinja2 templates that populate the value of these fields. Computed fields are available on all data models that currently support custom fields.

Config Context JSON Schemas (#274)

While config contexts allow for arbitrary data structures to be stored within Nautobot, at scale it is desirable to apply validation constraints to that data to ensure its consistency and to avoid data entry errors. To service this need, Nautobot supports optionally backing config contexts with JSON Schemas for validation. These schema are managed via the config context schema model and are optionally linked to config context instances, in addition to devices and virtual machines for the purpose of validating their local context data. Please see the docs for more details.

Just like config contexts, config context JSON schemas can optionally be managed via a Git repository.

Dynamic Navigation Menus (#12)

Applications and plugins can now define tabs, groups, items and buttons in the navigation menu. Using navigation objects a developer can add items to any section of the navigation using key names and weight values. Please see Application Registry for more details.

MySQL Database Support (#17)

MySQL 8.x is now fully supported as a database backend!

The installation and configuration guides have been revised to include MySQL. If you prefer MySQL or it is more easily supported in your environment, configuring Nautobot to use MySQL is as easy as changing value of ENGINE in your DATABASES setting to point to django.db.backends.mysql and installing the MySQL Python driver using pip3 install nautobot[mysql].

A new NAUTOBOT_DB_ENGINE environment variable has been added to allow for specifying the desired database engine at runtime without needing to modify your nautobot_config.py. Please see the configuration guide on DATABASES for more details on how to configure Nautobot to use MySQL.

Please see the MySQL setup guides for Ubuntu and CentOS to get started.

Plugin Defined Jinja2 Filters

Plugins can now define custom Jinja2 filters to be used when rendering templates defined within computed fields or custom links. To register your own filters, you may add a jinja_filters.py to your plugin and any filters defined there will be automatically registered and globally usable.

Please see the plugin development documentation on including Jinja2 filters to get started.

Read Only Jobs (#200)

Jobs may be optionally marked as read only by setting the read_only = True meta attribute. This prevents the job from making any changes to nautobot data and suppresses certain log messages. Read only jobs can be a great way to safely develop new jobs, and for working with reporting use cases. Please see the Jobs documentation for more details.

Saved GraphQL Queries (#3)

Saved GraphQL queries offers a new model where reusable queries can be stored in Nautobot. New views for managing saved queries are available; additionally, the GraphiQL interface has been augmented to allow populating the interface from a saved query, editing and saving new queries.

Saved queries can easily be imported into the GraphiQL interface by using the new navigation tab located on the right side of the navbar. Inside the new tab are also buttons for editing and saving queries directly into Nautobot's databases.

Additionally, two new GraphQL utility functions have been added to allow easy access to the GraphQL system from source code. Both functions can be imported from nautobot.core.graphql:

  1. execute_query(): Runs string as a query against GraphQL.
  2. execute_saved_query(): Execute a saved query from Nautobot database.

Changed

Background Tasks now use Celery (#223)

Celery has been introduced to eventually replace RQ for executing background tasks within Nautobot. All Nautobot core usage of RQ has been migrated to use Celery.

Note

Custom background tasks implemented by plugins are not part of Nautobot core functions

Prior to version 1.1.0, Nautobot utilized RQ as the primary background task worker. As of Nautobot 1.1.0, RQ is now deprecated. RQ and the @job decorator for custom tasks are still supported for now, but will no longer be documented, and support for RQ will be removed in a future release.

RQ support for custom tasks was not removed in order to give plugin authors time to migrate, however, to continue to utilize advanced Nautobot features such as Git repository synchronization, webhooks, jobs, etc. you must migrate your nautobot-worker deployment from RQ to Celery.

Please see the section on migrating to Celery from RQ for more information on how to easily migrate your deployment.

Warning

If you are running plugins that use background tasks requiring the RQ worker, you will need to run both the RQ and Celery workers concurrently until the plugins are converted to use the Celery worker. See the Migrating to Celery from RQ for details.

Fixed

HTTP "Remote end closed connection" errors (#725)

The example uwsgi.ini provided in earlier versions of the Nautobot documentation was missing a recommendation to include the configuration http-keepalive = 1 which enables support for HTTP/1.1 keep-alive headers.

Warning

If you are upgrading from an earlier version of Nautobot (including 1.1.0) you should check your uwsgi.ini and ensure that it contains this important configuration line.
