WSO2 error to find jdbc drivers on kubernetes

I'm trying to create a WSO2 APIM on my K8S, but I'm receiving an error when my pod starts, I receive the error using mysql and postgresql. I'm using overlay file.

Here is the pod error log, my overlay file and the list of jars inside of container.

pod files enter image description here

I tried to updload the .jar copying manually.

kubectl cp postgresql-42.7.5.jar wso2-wso2am-all-in-one-am-deployment-pod:/home/wso2carbon/wso2am-4.4.0/lib/ -n wso2

I tried to map a volume with the .jar, but I received a lot of errors about the deployment name.

I'm trying to create a WSO2 APIM on my K8S, but I'm receiving an error when my pod starts, I receive the error using mysql and postgresql. I'm using overlay file.

Here is the pod error log, my overlay file and the list of jars inside of container.

pod files enter image description here

I tried to updload the .jar copying manually.

kubectl cp postgresql-42.7.5.jar wso2-wso2am-all-in-one-am-deployment-pod:/home/wso2carbon/wso2am-4.4.0/lib/ -n wso2

I tried to map a volume with the .jar, but I received a lot of errors about the deployment name.

Sorted by: Reset to default 0

Files that we are adding/copying to containers will not persist and will be lost when the container/pod rollout.

Therefore, you need to persist the jdbc connector jar files by using config maps or using persistent Volumes.

For further info please refer to [1].
