Matching application.yaml file for two specific profiles

Question

Relevant similar (unanswered) question

I am having troubles implementing a simple configuration matrix for multi-tenant multi-environment Spring Boot application.

We have defined two sets of profiles: country_[iso2] (the tenant!), e.g. country_uk, country_ro, country_de; and the environment, development, test, qa, prod

The thing is I now need to inject some URLs that depend/change according to the combination tenant and environment. A matrix configuration.

And since there is a large number of properties to set, I haven't been following the approach of the linked answer, instead I have created multiple dash-separated-name files

• application.yaml (common for all)
• application-country_xx.yaml (all environments in xx share this)
• application-country_xx-development.yaml (supposed to match country_xx & development)
• etc.

When I start the application with either country_xx, development, or the opposite, I don't get the value for the property I have set. I am using @ConfigurationProperties.

In order not to end up with a huge single YAML file I don't like to merge every file into one and using the spring.profiles key. I prefer separate files.

Am I missing something here?

This is not possible in Spring. Profiles are taken one at a time

Source code

private Set<StandardConfigDataReference> getProfileSpecificReferences(ConfigDataLocationResolverContext context,
            ConfigDataLocation[] configDataLocations, Profiles profiles) {
        Set<StandardConfigDataReference> references = new LinkedHashSet<>();
        for (String profile : profiles) {
            for (ConfigDataLocation configDataLocation : configDataLocations) {
                String resourceLocation = getResourceLocation(context, configDataLocation);
                references.addAll(getReferences(configDataLocation, resourceLocation, profile));
            }
        }
        return references;
    }

The above evaluates one profile at a time, not all the combinations
