One of the key elements of working with Ansible is Python. Python is an important programming language that simplifies a lot of tasks. Ansible leverages this language to help you automate IT processes, configure systems and provision powerful infrastructure.
It is good to know which version of Python Ansible is using. This can help you determine the compatibility of your existing modules and figure out if you need to upgrade the Python version or Ansible itself. This also helps in troubleshooting any issues you might encounter while running Ansible playbooks.
There are multiple ways to find out the Python version used by Ansible. One method is by using the ‘ansible-config dump’ command. This will print all the Ansible configuration, which includes the Python version. Another option is by using the ‘ansible’ command with the ‘–version’ flag. This will print the Ansible version, along with the name of the current Python interpreter.
Identify Python Ansible Version using Command Line
There are multiple ways to identify the version of Python that Ansible is using. One of the most straightforward methods is to use the command line. Here’s a step-by-step guide on how to do it:
Using the ansible –version flag
The ‘ansible –version’ command displays the version of Ansible and the Python interpreter it is using. Here’s an example:
Command | Output |
---|---|
ansible –version | ansible 2.9.16 config file = /etc/ansible/ansible.cfg configured module search path = [‘/home/user/.ansible/plugins/modules’, ‘/usr/share/ansible/plugins/modules’] ansible python module location = /usr/lib/python3.8/site-packages/ansible executable location = /usr/bin/ansible python version = 3.8.10 (default, Oct 7 2021, 19:20:08) [GCC 9.4.0] |
As you can see, the output includes the version of Ansible (2.9.16) and the version of Python it is using (3.8.10).
Using the python –version flag
Another method to determine the Python version used by Ansible is via the ‘python –version’ command. This command directly invokes the Python interpreter and displays its version. Here’s an example:
Command | Output |
---|---|
python –version | Python 3.8.10 |
The output simply shows the Python version, in this case, it’s 3.8.10. Keep in mind that this method only provides the Python version, not the Ansible version.
Check Version via Ansible’s inbuilt Python Module
Ansible provides a native Python module, `ansible.builtin.setup`, which offers a convenient way to retrieve information about the Python interpreter used by Ansible. This module exposes a variable named `ansible_python_version`, which contains the version number of the Python interpreter.
To utilize this module, simply include the following code block in your Ansible playbook:
- name: Get Python version
setup:
register: python_version
This will execute the `setup` module and store the output in a variable named `python_version`. You can then access the Python version information by referencing the `ansible_python_version` key within the `python_version` variable.
Playbook | Output | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
- name: Get Python version setup: register: python_version |
TASK [Get Python version] *** ok: [localhost]
By leveraging these commands, you gain a comprehensive view of the Python versions installed on your system and their designated roles. This knowledge proves invaluable in managing and utilizing various Python versions for specific projects or tasks. Examine the Docker ImageIf you're utilizing Ansible within a Docker container, you can inspect the image to determine the Python version. To do so, follow these steps: 1. Pull the Docker ImageBegin by pulling the Ansible Docker image using the following command: ``` 2. Run the Docker ContainerNext, run the Docker container with the `-it` flag to enter interactive mode and the `--rm` flag to clean up the container upon exit: ``` 3. Check the Python VersionWithin the container, you can now check the Python version using the following command: ``` This will display the Python version installed within the container, which corresponds to the Ansible version being utilized. 4. Inspect the Docker Image Using Ansible-LintAnsible-Lint is a static code analyzer that can provide additional insights into your Ansible environment, including the Python version used. To install Ansible-Lint, run the following command: ``` Once installed, you can inspect the Docker image using Ansible-Lint with the following command: ``` This will provide a detailed report of your Ansible environment, including information about the Python version. The report will contain a section titled "Python interpreter," which will specify the Python version used by the Ansible image. Inspecting Environment VariablesInspecting environment variables is a common way to determine the version of Python used by Ansible. Here's a step-by-step guide: 1. Open a Terminal or Command PromptOpen a terminal window or command prompt on the server or workstation where Ansible is installed. 2. Type the Following CommandEnter the following command to display the Python version: ``` bash 3. Check the OutputThe command will output the path to the Python executable. The first line of the output typically includes the Python version:
4. Verify the Ansible Python VersionTo confirm that the Python version displayed matches the version used by Ansible, type the following command: ``` bash 5. Check the OutputThe output of the command will include the Python version used by Ansible. If it differs from the version displayed in Step 3, you may need to update Ansible or your Python installation: ``` bash Reading the Ansible Configuration FileThe Ansible configuration file is located at
The path specified after To determine the version of Python that is installed at this path, run the following command:
This command will output the version of Python that is installed at the specified path. Using Python Virtual EnvironmentsIf you are using Python virtual environments, you can specify a different Python interpreter for Ansible to use. To do this, add the following line to your Ansible configuration file:
Replace Using the Ansible Interpreter PluginStarting with Ansible 2.9, you can use the
Replace Reviewing the Python Package Manager (pip)The Python Package Manager (pip) is a versatile tool used to install, update, and manage Python packages. It offers a convenient way to access a vast repository of pre-built software packages, simplifying the installation process and ensuring compatibility with various Python environments. Installing Pip for Various Python VersionsTo determine the version of Python that Ansible is using, it's crucial to first ensure that pip is installed and configured properly. Here are the steps to install pip for different Python versions:
Verifying Pip InstallationOnce pip is installed, verify its successful installation by running the following command:
This command should output the version of pip installed on your system. #### Using Pip to Check Python Version To determine the version of Python that Ansible is using, run the following command:
