Hocon | Hocon IConfigurationSource for aspnet configuration | Configuration Management library

I am setting up a ktor api that connects with a postgres container in docker. I can get everything working when I hard code things. When I try to use the hocon config and print values I can see my dburl and dbuser but when I print my dbpassword I get an address like value.

Here is my hocon config:

I have this application using Akka.net cluster feature. The people who wrote the code have left the company. I am trying to understand the code and we are planning a deployment.

The cluster has 2 types of nodes

QueueServicer: supports sharding and only these nodes should participate in sharding.
LightHouse: They are just seed nodes, nothing else.

Lighthouse : 2 nodes
QueueServicer : 3 Nodes

I see one of the QueueServicer node unable to join the cluster. Both lighthouse nodes are refusing connection. It constantly tries to join and never succeeds. This has been happening for the last 5 days or so and the node is never dying also. Its CPU and memory usage is high. Also It doesn't have any queue processor actors running when filtered search through the log. It takes long hours for Garbage collection etc. I see in the log for this node, the following.

{"timestamp":"2021-09-08T22:26:59.025Z", "logger":"Akka.Event.DummyClassForStringSources", "message":Tried to associate with unreachable remote address [akka.tcp://myapp@lighthouse-1:7892].

There are other "Now supervising", "Stopping" "Started" logs which I am omitting here.

Can you please verify if the HCON config is correct for split brain resolver and Sharding?

I think LightHouse/SeeNodes should not have the sharding configuration specified. I think it is a mistake. I also think, split brain resolver configuration might be wrong in LightHouse/SeedNodes and should not be specified for seed nodes.

I appreciate your help.

Here is the HOCON for QueueServicer Trimmed

akka {
    loggers = ["Akka.Logger.log4net.Log4NetLogger, Akka.Logger.log4net"]
    log-config-on-start = on
    loglevel = "DEBUG"
    actor {
        provider = cluster
        serializers {
            hyperion = "Akka.Serialization.HyperionSerializer, Akka.Serialization.Hyperion"
        }
        serialization-bindings {
            "System.Object" = hyperion
        }
    }

I have defined the values.yaml like the following:

Currently I'm using the akka.net lighthouse docker image which is on dockerhub. Together with Akka.Bootstrap.Docker it's nice to override akka hocon configuration from the environment variables. I've set the following environment variables in my k8s deployment file

I'm new to rust and want to understand how to load config from file to use it in code.

In main.rs and other files i want to use config loaded from file:

I have a case class like the following:

Using Ktor as a web server and configuring it with the (HOCON) application.conf file.

I've setup a default password for connecting to a database in the configuration, as well as the ability for it to be overridden with an environment variable.

When the server starts, the configurations is printed to the console (and probably in future stored in logs), the problem is that the password is plainly visible.

Does anyone know of a way to prevent this?

Representative application.conf:

I am trying to setup a custom @ConfigurationProperties class loaded from a HOCON syntax .conf file.

I have a Class annotated with @PropertySource(factory=TypesafePropertySourceFactory.class, value = "classpath:app.conf")

I have following HOCON config:
