ECS FluentBit container is failed to start

Question

I am using Firelens to stream logs to cloudwatch. The fluentbit container is failing to start.

```
AWS for Fluent Bit Container Image Version 2.28.4
Fluent Bit v1.9.9
* Copyright (C) 2015-2022 The Fluent Bit Authors
* Fluent Bit is a CNCF sub-project under the umbrella of Fluentd
* https://fluentbit.io
[2022/12/02 05:06:48] [error] [config] error in /fluent-bit/etc/fluent-bit.conf:32: key has an empty value
[2022/12/02 05:06:48] [error] configuration file contains errors, aborting.
```
I didn't  make any change to this file "/fluent-bit/etc/fluent-bit.conf" . I tried in both ecs & fargate launch type  and both custom & aws default conf. I tried in all the possibilities of the ECS & fluentbit combinations. Everywhere I am getting the same error. Please help me to resolve this.

ECS Agent Version: 1.66.2
Platform: Linux
Tried in both intel & graviton still getting the same error.

Answer

If you want an easy way to get using FluentBit, which is amazing btw, take a look at using FireLens which would configure a lot of things for you right off the back.

What image did you use to have fluentbit?

If there are more things you'd want to do on top of firelens, you could use [ECS Compose-X](https://docs.compose-x.io) which has a built-in mechanism to help with FireLens & add more fluent bit extensions. See [these example](https://github.com/compose-x/compose-x-firelens-examples) to get started.
