When Cisco extended the deadline for the DevNetClassof2020 though, I took that as a sign and started my journey at short notice towards the end of 2020. Now you can learn what I think about the exam and the way I prepared.Continue reading “DevNet Associate – Travel Report”
So far this little InfraAsCode series was all about declarative Ansible playbooks and Git version control. In this last post we go full circle and discover how CI/CD pipelines helps with automation workflows, taking full advantage of good software development practices.Continue reading “Network InfrastructureAsCode with Ansible & Git – Part 3”
In part one we learned how to use Ansible and a data model to represent infrastructure as code. Now it’s time to introduce Git as the central network automation tool to use the advantages that result from working with text files.
I cannot emphasize enough how important this step is to long-term success with an automation initiative. Unversioned files with funny names in a random directory are not the solution.Continue reading “Network Infrastructure As Code With Ansible & Git – Part 2”
Infrastructure as code is all the rage, but sounds hypercomplex. How should it be possible to represent a router or even a whole network as code? We definitely need deep software development skills and an extensive version control plus CI/CD pipeline, right? Well, no! Actually, it’s pretty darn simple and by the end of this blog post you might wonder what took you so long to get started.Continue reading “Network Infrastructure As Code With Ansible – Part 1”
Tired of scrolling through massive directories on a file server, flooded with config files? Easy to implement ‘backup’ solution at day one (IOS archive?), but often based on debatable, unreliable protocols like TFTP, combined with great challenges in tracking changes on day two.Continue reading “Configbackup with Ansible + Git”
