Why the container life is less than a week ??

[Manikya Holla]

Hi,

I am Amitha. I have query on Container.
I read that ,container life in production is 1 or 2 days. Wondering why they get killed so soon ?
Any input ?

Containers' short lifetimes and increased density have significant implications for infrastructure monitoring. They represent an order-of-magnitude increase in the number of things that need to be individually monitored. Monitoring solutions that are host-centric, rather than role-centric, quickly become unusable. We thus expect Docker to continue to drive the sea change in monitoring practices that the cloud began several years ago.

Is it because, new Application changes keep coming everyday and CI/CD deploys more builds per day to deployment ?

Hi Amitha,

Essentially, it can be many things, but I guess it filters out to two :-

1. If there is a change, you take that container out and put in a new container with your change.
1. If this doesn't work, you take out the new container with your change and put back in the old one ( rebuilt )
2. If it works, you keep it that way until your next change comes up.

Now, if your change is a month away and you are doing things manually, I don't see the necessity of using a container based approach.

If you are doing ~5 builds a day, then yeah, you fall into the above category that two steps repeat ( as in a cycle ).

Docker accelerates application deployment thanks to seamless dependency management.

The word is "replace" and not "repair" !

As a result, depending on how often you 'replace' the application, you are going to see a docker container restart.
