Why is Fluentd Azure blob plugin not working in kubernetes
azure-storage-append-blob plugin is not installed by default. So you need to install it. Docs on how to install Fluentd plugin is here.
As said by @ArghyaSadhu in his answer, Currently fluentd docker image does not come with azure blob plugin pre-installed. We can obtain the docker image and customize it. Please refer to the following link on how to customize fluentd's docker image. https://github.com/bitnami/bitnami-docker-fluentd#customize-this-image
