General and Concepts

  • Declarative Deployments & why it matters

Over the last 30 years, the Configuration Management community has learned that using a declarative approach to resource management is beneficial for both stability and change management. How does this apply to the new paradigm of Kubernetes deployments?

YAML has become the de-facto standard to express resources in many fields linked to DevOps practices. What are YAML's strengths and weaknesses, and what are the other options going forward?

  • Software/script => have you considered packaging it?
  • binary/large data file => add metadata (git + vcsrepo type, maybe even git-annex or git-lfs?)

                How to diff PDF files with Git
              
          

        

      

        

  

      

    
One can use MD5 or plain text diff to see differences in PDF files. If that's not enough, here's how to use diff-pdf which knows how to diff based on appearance or words:


    

  • brew install diff-pdf
    • 

  • edit your ~/.gitconfig to add this:
    • 



[difftool "diffpdf"]
  cmd = diff-pdf --view \"$LOCAL\" \"$REMOTE\"
