Flink client will automatically ship the "flink-conf.yaml" and "log4j-console.properties" under FLINK_HOME/conf directory on the client side.

After the application is submitted successfully, you could find a ConfigMap named "flink-config-<cluster-id>".

If you want to mount your own ConfigMaps, it could not be supported now. We will get it done via pod template[1]. It is still in progress and

have a PR[2] waiting for review.

thank you Yang

but is there a way I can load my own ConfigMap and specify it via the dynamic argument?

it seems that kubernetes.hadoop.conf.config-map.name exists but it's only for custom hadoop config

I'd want to encapsulate all the my custom config (flink-conf.yaml, log4j-consle.yaml etc) and feed it into native K8S CLI

If you are setting the config options in flink-conf.yaml, then you could directly add the following example.

kubernetes.jobmanager.annotations: iam.amazonaws.com/role:'arn:aws:iam::XXXXXXXX:role/XX/XXXX'

However, if you are using the dynamic properties in the CLI. Then the configuration value should also

be wrapped with a double quote. It just because we need to escape the value with single quote.

-Dkubernetes.jobmanager.annotations="iam.amazonaws.com/role:'arn:aws:iam::XXXXXXXX:role/XX/XXXX'"

It seems that IAM is not a common feature in Kubernetes. But from the documentation of AWS[1],

I think it could be specified via service account[2]. Hope this helps.

I think it will be more generic question of how I inject IAM roles in Native Kubernetes pods

I'm using Kubeiam and seems the namespace annotation doesn't work

Hi team, I'm using Native Kubernetes annotation config

kubernetes.jobmanager.annotations

and I'm facing some problem with parsing.

I use annotation

iam.amazonaws.com/role:'arn:aws:iam::XXXXXXXX:role/XX/XXXX'

but seems no matter what I do, the colon is getting parsed for key, value. can anyone help?
