\frametitle{Outline}
|

\begin{itemize}
|
||||
\item From configuration management
|
||||
\item to puppet and existing products
|
||||
\item to cdist development, design and status
|

\end{itemize}

|

\frametitle{Why Configuration Management?}
|
||||
\begin{itemize}
|
||||
\item Needed for automatisation
|
||||
\item Removes burden on reinstallation
|
||||
\item Helps to scale to a big number of hosts
|
||||
\item Has documentation character
|
||||
\end{itemize}

{
|
||||
\frametitle{Why cdist?}
|
||||
\begin{itemize}
|
||||
\item Stopped using puppet (mostly due to bugs and non-intuitive configuration)
|
||||
\item Cfengine2 is more complicated
|
||||
\item Cfengine3 spams into your logfiles
|
||||
\item Did not investitage to deep into chef (based on puppet) or bcfg2
|
||||
\end{itemize}

\begin{frame}
|
||||
\frametitle{Features}
|
||||
\begin{itemize}
|
||||
\item Simplicity: There is only one type to extend cdist called type
|
||||
\item Design: Type and core cleanly seperated
|
||||
\item Design: Sticks completly to the KISS (keep it simple and stupid) paradigma
|
||||
\item Design: Meaningful error messages - do not lose time debugging error messages
|
||||
\end{itemize}
|
||||
\end{frame}
|
||||
|
||||
\begin{frame}
|
||||
\frametitle{Features (2)}
|
||||
\begin{itemize}
|
||||
\item Design: Consistency in behaviour, naming and documentation
|
||||
\item Design: No surprise factor: Only do what is obviously clear, no magic
|
||||
\item Design: Define target state, do not focus on methods or scripts
|
||||
\item Design: Push architecture: Instantly apply your changes
|
||||
\end{itemize}
|
||||
\end{frame}
|
||||
|
||||
\begin{frame}[fragile]
|
||||
\frametitle{Features (3)}
|
||||
\begin{itemize}
|
||||
\item Small core: cdist's core is very small - less code, less bugs
|
||||
\item Fast development: Focus on straightforwardness of type creation is a main development objective
|
||||
\end{itemize}
|
||||
\end{frame}
|
||||
\begin{frame}[fragile]
|
||||
\frametitle{Features (4)}
|
||||
\begin{itemize}
|
||||
\item Requirements, Scalability: No central server needed, cdist operates in push mode and can be run from any computer
|
||||
\item Requirements, Scalability, Upgrade: cdist only needs to be updated on the master, not on the target hosts
|
||||
\item Requirements, Security: Uses well-know SSH as transport protocol
|
||||
\item Requirements, Simplicity: Requires only shell and SSH server on the target
|
||||
\end{itemize}
|
||||
\end{frame}
|
||||
|
||||
\begin{frame}
|
||||
\frametitle{Features (5)}
|
||||
\begin{itemize}
|
||||
\item UNIX: Reuse of existing tools like cat, find, mv, ...
|
||||
\item UNIX, familar environment, documentation: Is available as manpages and HTML
|
||||
\item UNIX, simplicity, familar environment: cdist is written in POSIX shell
|
||||
\item UNIX, simplicity, familar environment: cdist is configured in POSIX shell
