The system doesn't support reading configurations from environment/system variables for file repository/conf/axis2/axis2.xml

[yhilem]

Hi,
I have defined a system variable in repository/conf/axis2/axis2.xml :

    <parameter name="keystore" locked="false">
        <KeyStore>
            <Location>${wso2_keystores_keystore_location}</Location>
            <Type>JKS</Type>
            <Password>wso2carbon</Password>
            <KeyPassword>wso2carbon</KeyPassword>
        </KeyStore>
    </parameter>

</transportReceiver>

But apparently, reading the environment variables is not supported for the file axis2.xml.
At startup, I have this exception:

Some values (variables) are specific to each environment (DEV, QA, PRE-PROD, PROD).
If I can not put them in variables, this will result in the creation of as many docker images as the environments for the same component.

In addition, it is already supported for other configuration files (https://wso2.org/jira/browse/CARBON-15791).

Hi Youcef,

Reading all configurations from environment variables is not currently supported for axis2.xml. Therefore the preferred way is to maintain separate images for each environment.

Thanks,
Isuru H.

Thank you.

From APIM v3 onward, this will be support by default. All configs can be read from environment variables.
