Start fluentd as non-root user

[Vivianmeme]

Hi,

I'm trying to bring up fluentd container as a non-root user(e.g. fluentd) within k8s cluster.

bash-4.1$ id

uid=999(fluent) gid=999(fluentd) groups=999(fluentd)

However met the following read-only filey system error:

If adding the user and group options, the Operation not permitted error being thrown:

Do I have to build a new image which gives the user "fluent" enough permission?

Any help is appreciated:)

Ok, I fixed it. 

The root cause is that /tmp is read-only for non-root user inside fluentd container. And this issue can be resolved by mounting a volume (empty dir type) to fluentd.
