ansible-navigator is the new command line utility (CLI) introduced in Ansible Automation Platform 2, for running and developing Ansible automation content. ansible-navigator can be used to execute a playbook as follows.
$ ansible-navigator run site.yaml -m stdoutNew to Ansible Automation Platform 2 ? Read Introducing Red Hat Ansible Automation Platform 2.1 for more details.
ansible-navigator also has the Text User Interface (TUI) which will help you to visualize the Ansible execution better than the ansible-playbook command.
$ ansible-navigator run site.yamlAnsible navigator can be installed using multiple methods as follows.
## Using Python
$ python3 -m pip install ansible-navigator --user
## Using package manager on RHEL
## A subscription is required
$ dnf install \
--enablerepo=ansible-automation-platform-2.2-for-rhel-8-x86_64-rpms \
ansible-navigatorRefer to the navigator installation document or the Red Hat documentation to learn more.
The changes are very easy to adopt and commands are self-explanatory subsets.

ansible-navigator welcome will show the text user interface (TUI) of Ansible Navigator with instructions and subcommands. (You will get the same interface when you execute ansible-navigator without any arguments)
You can execute the subcommands from the same TUI like a dashboard.
:doc -Checking documentation
:doc dnfIt will load the result in the same TUI interface.

15│ - When used with a `loop:` each package will be processed individually, it is much
16│ more efficient to pass the list directly to the `name` option.
17│ - Group removal doesn't work if the group was installed with Ansible because upstream
18│ dnf's API doesn't properly mark groups as installed, therefore upon removal the
19│ module is unable to detect that the group is installed (https://bugzilla.redhat.com/show_bug.cgi?id=1620324

Execute the playbook with a more summarised output instead of logs and details.
$ ansible-navigator run site.yml -m stdout
If you want to get the standard output the same as the ansible-playbook command, then add -m stdout at the end of your ansible-navigator run command as below.

}You can replay the execution by using the artefacts from the previous run but you need to enable the saving of artefacts in the ansible-navigator.yml configurations.

ANSIBLE_NAVIGATOR_CONFIG(settings file path environment variable if set)./ansible-navigator(project directory)~/.ansible-navigator(home directory)
The settings file can be in JSON or YAML format.
You can configure the execution environments, development styles, and even the code editor details.
$ cat ansible-navigator.yml
