We’ll show you the steps needed to install Ansible on your machine, configure it to connect a Docker host (localhost) and deploy a container.

Ansible docker network how to#
You will explore how to adapt to other open source tools and write Python programs accordingly. Ansible is a powerful and simple configuration management tool that can be used in many different ways for managing your infrastructure and services. The previous task indeed does this, so just remove the dependson attribute and the task should complete properly. You should create the containers in order to simulate the dependency tree. Finally, you will learn to monitor your network device’s CPU utilization with your Python application and then use a free Twilio SMS account to send an SMS to your smartphone using the Twilio API. The Ansible dockercontainer module indeed has no dependson attribute. You will have made a quick start on Ansible and pyATS (Genie) and learned how sending an email works on Linux and Python using Sendmail. At the end of this chapter, you will be able to work in a Python virtual environment for testing without affecting the existing Python setup. We have to learn how to get around these obstacles and still implement our solutions (or applications) in such a production environment. In a production environment, often we do not always get a dedicated Linux server for testing and implementation often you will be given a limited resource on a Linux server with shared access with other engineers. Thus far in this book, we have focused on using Python’s basic Telnet and SSH remote access methods to probe, configure, and manage network devices in the lab topology. It should definitely not mean "all 2000 reachable hosts that are accidentally reachable".This chapter is designed to introduce you to Python virtualenv and to Docker concepts and expose you to other ways of exploring Python external modules and features. But that probably depends on how you use this Ansible file. When you wrote the code, it was immediately clear to you what they are supposed to mean, but will that still be the case in 2 years? I'd choose longer, more expressive names.Īll the rest looks good, and it serves as a nice and brief instruction how to set up a Docker Swarm cluster. I found the filenames in /tmp a bit short. Same for pip3, Python packages also have versions, and if you want a reproducible setup, you must use fixed version numbers instead of always taking the latest versions. Also, downloading the now-current file prevents the setup from being reproducible.
Ansible docker network download#
You should verify this download as well, just as you do with the Debian packages above. You trust to always serve you the file you expect. Speaking of which, you don't specify which versions of the packages you want to have installed. In case the hosts die all of a sudden, it should be possible to set up the exact same setup as before. Is it a Debian, Ubuntu, Alpine, Arch, Red Hat (probably not)? This should be documented somewhere. Talking of the distribution: From reading the Ansible file, I have no idea what base system I should install before applying Ansible to it. Isn't there some newer release of that distribution? You are basing the system on a Linux distribution that still has Python 2 installed as default. Verifying the download is something that the apt_key module should provide out-of-the-box, or its documentation must warn about the practice of downloading an untrusted key, otherwise its authors have no clue of IT security. Since the hash by itself does not tell a story, I'd write a comment along it, summarizing the information from the GPG key, something like: # : 9DC858229FC7DD38854AE2D88D81803C0EBFCD88 Then I'd compute a hash of the file and use that to verify the download.
Ansible docker network Offline#
Instead, I would download this key and verify offline that it comes from the person it says. You currently trust the URL of that task to always provide the correct GPG key. The basic idea of a GPG key is that it provides a trust anchor.

Here are some things I noted by just looking at the code:
Ansible docker network code#
I have done some Ansible tasks 5 years ago, so I looked at your code just out of interest, and I didn't read any documentation. maybe you could post an answer showing how you would write the playbook using this module? my playbook was pretty simple to write, if using the module can save time, i dont mind changing.
