Faraz, I use git every day.
We have Bitbucket here, and have linked the repositories to Jira for our
sprint planning and kanban.
Anyway - you say something very relevant "I have never had a need to go
back to an older version of my script."
It is not only about rollback to older versions. If you are workign in a
small team, I think you really have to have the production version of
scripts defined somewhere.
For instance I work with PBS Hooks, which are Python scripts. I need to
know which are the ones in use on our PBS server.
(Yes -you can do a fetch of the script from the PBS server. I know how to
But it is cleaner and easier to point towards the master of that repo and
say - these are the PBS hooks we are using right now.
I can then create a branch and go off to implemen tchanges on our test
cluster - knowing that the master branch remains untouched.
When we are happy I get a colleague to to a merge.
Regarding the command line of git, I do agree that it can be confusing.
I discovered the Atom editor, which has an in-build GUI for git.
Also now start to think about disaster recovery, and software defined
Firstly, lets us be extreme. Your data centre burns down. Your management
are breathing down your neck. They want the service back up and running.
Funds magically appear, and a bunch of servers appears on the loading dock
of the new data centre.
Are you confident those scripts can be integrated onto the new setup?
Also the trend now is to software defined infrastructures. You stand up new
nodes and configure them using defined rules.
You may want to copy some of those scripts onto the nodes - lets' say they
are PBS hooks, or pre job healthchecks.
I admit we are nowhere near doing that effictively, but it is our goal.
