Managing Ansible environments on MacOS with Conda

If you’re a Python developer utilizing MacOS and concerned with Ansible administration, you might need to use the Conda bundle supervisor to maintain your Ansible work separate out of your core OS and different native initiatives.

Ansible is predicated on Python. Conda is just not required to make Ansible work on MacOS, but it surely does make managing Python variations and bundle dependencies simpler. This means that you can use an upgraded Python model on MacOS and hold Python bundle dependencies separate between your system, Ansible, and different programming initiatives.

There are different methods to put in Ansible on MacOS. You may use Homebrew, however if you’re into Python improvement (or Ansible improvement), you would possibly discover managing Ansible in a Python digital atmosphere reduces some confusion. I discover this to be less complicated; quite than making an attempt to load a Python model and dependencies into the system or in /usr/native, Conda helps me corral all the pieces I would like for Ansible right into a digital atmosphere and hold all of it utterly separate from different initiatives.

This article focuses on utilizing Conda to handle Ansible as a Python undertaking to maintain it clear and separated from different initiatives. Read on to learn to set up Conda, create a brand new digital atmosphere, set up Ansible, and take a look at it.


Recently, I wished to be taught Ansible, so I wanted to determine the easiest way to put in it.

I’m usually cautious of putting in issues into my each day use workstation. I particularly dislike making use of handbook updates to the seller’s default OS set up (a desire I developed from years of Unix system administration). I actually wished to make use of Python three.7, however MacOS packages the older 2.7, and I used to be not going to put in any international Python packages that may intrude with the core MacOS system.

So, I began my Ansible work utilizing an area Ubuntu 18.04 digital machine. This supplied an actual degree of secure isolation, however I quickly discovered that managing it was tedious. I got down to see easy methods to get a versatile however remoted Ansible system on native MacOS.

Since Ansible is predicated on Python, Conda gave the impression to be the best answer.

Installing Conda

Conda is an open supply utility that gives handy package- and environment-management options. It might help you handle a number of variations of Python, set up bundle dependencies, carry out upgrades, and keep undertaking isolation. If you might be manually managing Python digital environments, Conda will assist streamline and handle your work. Surf on over to the Conda documentation for all the small print.

I selected the Miniconda Python three.7 set up for my workstation as a result of I wished the most recent Python model. Regardless of which model you choose, you possibly can all the time set up new digital environments with different variations of Python.

To set up Conda, obtain the PKG format file, do the same old double-click, and choose the “Install for me only” possibility. The set up took about 158MB of area on my system.

After the set up, convey up a terminal to see what you’ve got. You ought to see:

  • A brand new miniconda3 listing in your residence
  • The shell immediate modified to prepend the phrase “(base)”
  • .bash_profile up to date with Conda-specific settings

Now that the bottom is put in, you’ve got your first Python digital atmosphere. Running the same old Python model verify ought to show this, and your PATH will level to the brand new location:

(base) $ which python
(base) $ python --version
Python three.7.1

Now that Conda is put in, the following step is to arrange a digital atmosphere, then get Ansible put in and operating.

Creating a digital atmosphere for Ansible

I need to hold Ansible separate from my different Python initiatives, so I created a brand new digital atmosphere and converted to it:

(base) $ conda create --name ansible-env --clone base
(base) $ conda activate ansible-env
(ansible-env) $ conda env listing

The first command clones the Conda base into a brand new digital atmosphere referred to as ansible-env. The clone brings within the Python three.7 model and a bunch of default Python modules that you may add to, take away, or improve as wanted.

The second command modifications the shell context to this new ansible-env atmosphere. It units the correct paths for Python and the modules it accommodates. Notice that your shell immediate modifications after the conda activate ansible-env command.

The third command is just not required; it lists what Python modules are put in with their model and different information.

You can all the time change out of a digital atmosphere and into one other with Conda’s activate command. This will convey you again to the bottom: conda activate base.

Installing Ansible

There are numerous methods to put in Ansible, however utilizing Conda retains the Ansible model and all desired dependencies packaged in a single place. Conda supplies the pliability each to maintain all the pieces separated and so as to add in different new environments as wanted (as I will show later).

To set up a comparatively current model of Ansible, use:

(base) $ conda activate ansible-env
(ansible-env) $ conda set up -c conda-forge ansible

Since Ansible is just not a part of Conda’s default channels, the -c is used to look and set up from an alternate channel. Ansible is now put in into the ansible-env digital atmosphere and is able to use.

Using Ansible

Now that you’ve got put in a Conda digital atmosphere, you are prepared to make use of it. First, be sure the node you need to management has your workstation’s SSH key put in to the correct person account.

Bring up a brand new shell and run some fundamental Ansible instructions:

(base) $ conda activate ansible-env
(ansible-env) $ ansible --version
ansible 2.eight.1
  config file = None
  configured module search path = ['/Users/jfarrell/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /Users/jfarrell/miniconda3/envs/ansibleTest/lib/python3.7/site-packages/ansible
  executable location = /Users/jfarrell/miniconda3/envs/ansibleTest/bin/ansible
  python model = three.7.1 (default, Dec 14 2018, 13:28:58) [Clang (tags/RELEASE_401/ultimate)]
(ansible-env) $ ansible all -m ping -u ansible | SUCCESS =>
        "discovered_interpreter_python": "/usr/bin/python"
    "changed": false,
    "ping": "pong"

Now that Ansible is working, you possibly can pull your playbooks out of supply management and begin utilizing them out of your MacOS workstation.

Cloning the brand new Ansible for Ansible improvement

This half is solely optionally available; it is solely wanted in order for you further digital environments to switch Ansible or to soundly experiment with questionable Python modules. You can clone your principal Ansible atmosphere right into a improvement copy with:

(ansible-env) $ conda create --name ansible-dev --clone ansible-env
(ansible-env) $ conda activte ansible-dev
(ansible-dev) $

Gotchas to look out for

Occasionally you might get into bother with Conda. You can often delete a nasty atmosphere with:

$ conda activate base
$ conda take away --name ansible-dev --all

If you get errors that you just can not resolve, you possibly can often delete the atmosphere immediately by discovering it in ~/miniconda3/envs and eradicating all the listing. If the bottom turns into corrupt, you possibly can take away all the ~/miniconda3 listing and reinstall it from the PKG file. Just you’ll want to protect any desired environments you’ve got in ~/miniconda3/envs, or use the Conda instruments to dump the atmosphere configuration and recreate it later.

The sshpass program is just not included on MacOS. It is required provided that your Ansible work requires you to produce Ansible with an SSH login password. You can discover the present sshpass source on SourceForge.

Finally, the bottom Conda Python module listing could lack some Python modules you want to your work. If you should set up one, the conda set up <bundle> command is most well-liked, however pip can be utilized the place wanted, and Conda will acknowledge the set up modules.


Ansible is a strong automation utility that is price all the hassle to be taught. Conda is a straightforward and efficient Python digital atmosphere administration software.

Keeping software program installs separated in your MacOS atmosphere is a prudent method to take care of stability and sanity along with your each day work atmosphere. Conda might be particularly useful to improve your Python model, separate Ansible out of your different initiatives, and safely hack on Ansible.
