I can't decide which is more robust in real-life applications:
A) using fluentd docker logging driver - docker sends its data to fluentd driver
B) using fleund to tail default docker json logs.
Why I have a problem with A? Well, it is like "inversion of control" principle in programming:
it is one more dependency, docker will not start if it is not set correctly
Filtering and formatting different types of logs may be a pain, when all logs are forwarded as stdout to the same port.
The biggest issue: in case of fluentd failure, there is no option to recover the logs!
I am leaning more to solution B, but I miss some experience on this subject. Do I miss something?
