Containers are immutable in nature once created it won't be modified even init containers also

@brahmaiahboddu5762 Ай бұрын

Hi Piyush, Thanks for the detailed explanation of the init container What about a sidecar container.

@TechTutorialswithPiyush Ай бұрын

sidecar containers are being created when you use an application that needs to gather some metrics/data from your pod itself. Monitoring application such as datadog is one of the usecase. We will cover that in a seperate video.

@karnajeetsawant5635 Ай бұрын

Hi Piyush. Thanks for making the concept easier. I have a question though. Can there be a situation where a deadlock occurs between the init container and the pod. If such a situation arises then how would one solve it?

@TechTutorialswithPiyush Ай бұрын

Thank you for the feedback. There wouldnt be a deadlock situation as init containers are always executed first and only after the successfull completion of init container, your main container will be executed.

@debillion Ай бұрын

Instead of each pod having its own sidecar container, is it possible for mutiple pods to use one shared pod container located somewhere? if yes, how can it be done?

@TechTutorialswithPiyush Ай бұрын

Replied this over the livestream but let me add the answer here as well. It is not possible for multiple pods to use one shared pod/container. It involves a lot of dependency on that shared container and other pods will be impacted if something happens to the shared container, it make the application tightly couple which is an anti-pattern of microservices.

@debillion Ай бұрын

@@TechTutorialswithPiyush Thanks for your reply. However, I am still not very clear. Once again, I have a bitbucket Pipelines. I want to use one shared Docker pod instead of the same sidecar in every pod. I have both the runner container and Docker container in a manifest but I wanted to know how to seperate the runner container from the docker container (sidecar container) so that I can run one Docker instance and multiple runner instances on one Kubernetes node.
