_______________________________________________Hello Adwait,
We will update the documentation to include information about the environment variables in the near future. Until then, you can find more information about the naming schema for these environment variables here: https://github.com/eclipse-basyx/basyx-java-components/tree/main/basyx.components/basyx.components.lib/src/main/java/org/eclipse/basyx/components/configuration
Thus, for MongoDB, the prefix is “BaSyxMongoDB_” followed by the property name.
E.g. BaSyxMongoDB_dbconnectionstring
Another remark: There is no property for the mongodb user, but you can include this and multiple other connection options in the connection string. See more information about this here:
https://docs.mongodb.com/manual/reference/connection-string/

Betreff: Re: [basyx-dev] Enabling persistence for BaSyx AAS data over AKS using Azure Cosmos DB API for MongoDB
Hi Basyx community,
I followed the https://github.com/eclipse-basyx/basyx-java-examples/, but found Environment variables does not reflect over Azure Kubernetes (AKS) Container.
Further I checked for environment variables for Kubernetes and found details - https://kubernetes.io/docs/tasks/inject-data-application/define-environment-variable-container/
These found working and I came up with below structure
env:
- name: BaSyxContext_contextPath
value: "/aasName"
- name: BaSyxAas_aas.backend
value: "MongoDB"
- name: BaSyxMongodb_dbuser
value: "cosmosdbapiformongo"
- name: BaSyxMongodb_dbname
value: "Data"
- name: BaSyxMongodb_dbconnectionstring
value: "ConnectionString"
- name: BaSyxMongodb_dbcollectionAAS
value: "assetadministrationshells"
- name: BaSyxMongodb_dbcollectionSubmodels
value: "submodels"
From this BaSyxContext_contextPath worked, and I can access the endpoint - http://IP:Port/aasName/shells
But I can't make connectivity with MongoDB and so aas.backend=InMemory remained as default. Reason could be - incorrect variable name format
- name: BaSyxAas_aas.backend
- name: BaSyxMongodb_dbuser
The name must have a specific format to follow and I am not sure where to learn it.
For example - BaSyxContext_contextPath
which is <Provider><PropertyFileName>_<PropertyName>
Here, provider is BaSyx.
Context is name of Context.property file.
contextPath is the property name in Context.property file
Could you please help me to have the names corrected?
Best Regards,
Adwait

Hello Adwait,
Currently, it is possible to configure the components with environment variables instead of property files. Here you can find an example that shows how to do that:
The only “configuration” you cannot include as an environment variable is an actual .aasx-File.
To connect to any MongoDB, you can set up the connection using the MongoDB-Connection string:
https://wiki.eclipse.org/BaSyx_/_Documentation_/_Components_/_MongoDB
https://docs.mongodb.com/manual/reference/connection-string/
Since Azure Cosmos DB API for MongoDB should be compatible with the MongoDB API, using it should work by default. Yet, we did not test the Azure Cosmos DB API for MongoDB in specific. Therefore, we would be glad to get your hands-on input and feedback about this.
Best Regards

Betreff: [basyx-dev] Enabling persistence for BaSyx AAS data over AKS using Azure Cosmos DB API for MongoDB
Hi Basyx community,
Good Day!
With reference to "Aasx_PackEx_Tutorial_-_EN_-_51_Connect_AASX_Server_Repository" earlier email, we have requirement of persisting the BaSyx AAS data in AKS [Azure Kubernetes services].
Our Understanding - To enable data persistence, AAS server image should be imported along configurations shown below [attached for reference]
1] aas.properties - aas.backend=MongoDB
2] mongodb.properties
Question -
1] Is there a possibility to upload these configurations in a yml file while uploading eclipsebasyx/aas-server:latest image over AKS?
2] If configuration in yml file is possible, then please provide guiding steps to achieve this. The yml configuration should align to Question 4] , to have data persisted in Azure Cosmos DB API for MongoDB.
3] If configuration in yml file is not possible, then please suggest alternate way where DockerHub / Azure Container Service / Azure Container Instance or Java Codebase customization is not required.
4] Can we use Azure Cosmos DB API for MongoDB to store data from BaSyx AAS image deployed over AKS?
Best Regards,
Adwait
