How to change *.properties after ant production - ant

I have 2 .properties files for my project on hybris .
First one is used for CI process and as a result a got 4 zip files with my already built platform(after ant production).
On my prod instance i need to switch to another properties because there are all my connections to extended services such as mysql solr.. etc
How i can do that without running all ANT steps.
. ./setantenv.sh && sync && ant config -Denv=my_new_properties
then ./hybrisserver.sh start doesn't work.
There is no information on wiki https://cxwiki.sap.com/display/release5/ant+production+improvements

Check if Updating Configuration Settings at Runtime will be useful for you. You will need to use the FileBasedConfigLoader class and the runtime.config.file.path property.
Other best practices include using system variables for secure settings like DB URL. See "Using Environment Variables instead of Files for Secure Settings" section in Configuring the Behavior of SAP Commerce.
Another option you can look at is to have different config folders for different environments (e.g. config-dev, config-prd), and pass it to ant. e..g -Denv=config--dev

How to set dependency-mapping binding in gradle bootBuildImage (Spring-boot 2.7.1, native)

I am using spring-boot 2.7.1 with native configuration as the guide follows in the link.
Spring native official doc
My problem is that when running bootBuildImage, the buildpack ["gcr.io/paketo-buildpacks/java-native-image:7.19.0"] is trying to download external dependency paketo-buildpacks/bellsoft-liberica from https://download.bell-sw.com/vm/22.3.0/bellsoft-liberica-vm-core-openjdk17.0.5+8-22.3.0+2-linux-amd64.tar.gz which is not allowed by company firewall.
I then researched that you can configure dependeny-mapping bindings towards these dependencies within required buildpack, at-least using this pack cli guide.
But when using purely pack-cli the gradle bootBuildImage gets a bit irrelevant and then I have to use some external tool to fix the native docker container and image. And I would like to only use the bootBuildImage to map these dependency-bindings.
I found this binding function within Gradle bootBuildImage docs. but I am not sure what string it expects, if the path should be similar to pack-cli config or not, can't find any relevant info.
The provided image show the bootBuildImage config
bootBuildImage {
builder = 'docker.io/paketobuildpacks/builder:tiny'
runImage = 'docker.io/paketobuildpacks/run:tiny-cnb'
buildpacks = ['gcr.io/paketo-buildpacks/java-native-image']
binding("bindnings/bellsoft-jre-config:/platform/bindings/bellsoft-jre-config")
environment = [
"BP_NATIVE_IMAGE" : "true",
]
}
The dependency-mapping config contains 2 files:
The type file contains:
echo "dependency-mapping" >> type
The sha256 (bellsoft-liberica) file 3dea0f7a9312c738d22b5e399b6ce9abe13b45b2bc2c04346beb941a94e8a932 contains:
'echo "https://download.bell-sw.com/vm/22.3.0/bellsoft-liberica-vm-core-openjdk17.0.5+8-22.3.0+2-linux-amd64.tar.gz" >> 3dea0f7a9312c738d22b5e399b6ce9abe13b45b2bc2c04346beb941a94e8a932'
And yes I'm aware that this is the exact same url, but this is just to test that the binding config is correctly setup. Because if ok it should fail on untrusted certificate when downloading instead.
Currently the build fails with:
Caused by: org.springframework.boot.buildpack.platform.docker.transport.DockerEngineException: Docker API call to 'localhost/v1.24/containers/create' failed with status code 400 "Bad Request"

Which i assume is caused by invalid binding config. But I can't find what is should be.
Paketo configuration (binding)
Dependency mapping bindings can be tricky. There are a number of things that have to be just right, or the buildpacks won't pick up the binding and won't map dependencies.
While there are talks of how we can change this in buildpacks to make swapping out dependencies easier, the short-term solution is to use binding-tool.
You can run bt dm -b paketo-buildpacks/bellsoft-liberica and it will go download the dependencies from the specified buildpack and generate the binding files for you.
It will by default download dependencies and write the bindings to $PWD/bindings but you can change that. For example, I like to put my dependencies in my home directory so I can share them across apps. Ex: SERVICE_BINDING_ROOT=~/.bt/bindings bt dm ..., or export SERVICE_BINDING_ROOT=~/.bt/bindings (or whatever command you run to set an env variable in your shell).
Once you have the bindings created, you just need to point your app to them. How you set the property differs between Maven & Gradle, but the value of the property is the same. It should be <local-path>:<container-path>.
The local path should be the full or relative path to where you created the bindings with bt dm. The container path should almost always be /platform/bindings. This maps your full set of bindings locally to the full set of bindings that the buildpacks will consume. In other words, put all of your bindings into the same directory locally, map that to /platform/bindings and the buildpacks will see everything.
For example with Gradle: binding("bindings/:/platform/bindings").
You can adjust the container path by setting SERVICE_BINDING_ROOT in the container as well, but it doesn't offer a lot of advantage.
You can also set multiple entries for bindings, so long as the paths are unique. So you could set binding("/home/user/.bt/bindings/foo:/platform/bindings/foo") and also binding("bindings/bar:/platform/bindings/bar"). That would let you take bindings from two different locations locally and map them into the /platform/bindings directory so both would be visible to buildpacks. This gives you more fine-grained control but as you can see becomes pretty verbose.
Details on configuring Maven and configuring Gradle for buildpacks can be found at those links.

How to read in other config information into a dropwizard service

I am building a dropwizard service which will connect to multiple data sources including mySQL and Elasticsearch. All the mySQL settings can be defined in the yaml config file which gets read in after running from the commandline.
But what about other settings that I need to read in for other data sources that I will connect with myself, for example Elasticsearch? Where can I define those settings?
I thought I could add another commandline Command - which I tried, but I can only run a single command (from the commandline) at a time - so I can't seem to run both the 'server' command as well as my custom command, 'custom' which is followed by the my own config file for elasticsearch.
How can I introduce settings either individually or from a file - which are defined at run time (not hard coded)?
Thanks
Anton
Check out the Dropwizard Core documentation on adding custom configuration.
You'd create an ElasticSearchFactory class similar to the MessageQueueFactory in the example, reference this in your Configuration (that's in turn referenced in your Application), and then the options you need can be added to your main yaml configuration.

Grails 3 plugins configuration

New to Grails 3- starting to port.
Have tried placing config values in application.groovy and application.yml within plugin conf dir to no avail - trying to read values from within plugin service fails. Adding values to the main application's application.groovy works.
What is the secret here? Previously I could load specific conf files via config.locations simply by naming them which was nice and simple. I've seen some resolutions that include needing to setup env vars with paths to config files which I'd like to avoid. Then they set up file URIs for dev and classpath URIs for other envs that will be war packaged - don't really want to do any of this.
Do we no longer have the ability to place config within a plugin and have that automatically merged with the applications config?
The plugin may provide config settings in grails-app/conf/plugin.yml.

Troubleshooting Grails merged configuration during application startup

Suppose I have a Grails application named myCoolApp.
Furthermore, suppose I have defined some basic properties in grails-app/conf/Config.groovy and grails-app/conf/DataSource.groovy under the test and production profiles.
Config.groovy is set to merge with the following .groovy external configuration file, if found at all:
grails.config.locations = ["file:${userHome}/.grails/${appName}-config.groovy"]
Finally, I have also defined, inside an external testing server, such a file, under a local *NIX user path:
/home/appServerTestUser/.grails/myCoolApp-config.groovy
Sadly, I find that for some reason, the external .groovy file's properties are not being merged when a Tomcat instance starts up.
What options do I have to make Grails tell me: "Oh, yes, I found your external config file at: /home/appServerTestUser/.grails/myCoolApp-config.groovy" and these are the properties I merged into Config.groovy?
Thanks!
File-based paths don't make much sense in a deployed app. It could work when deploying on your dev machine for testing, but will likely fail on any other machine. And it'll probably fail locally even if configured with the correct path since the process will like run as a different low-priviledge user.
You can use absolute paths, e.g. /etc/myapp/path/to/file, but this tends to couple deployment to filesystem structure, so if you develop in Windows and deploy on Linux it'd be tricky to get them both working.
So the best bet for Tomcat deployment is to use the classpath syntax. You can specify multiple files and it will load all that it finds, so I usually have one entry for local dev and one for the deployed app:
grails.config.locations = [
"classpath:${appName}-config.groovy",
"file:./${appName}-config.groovy"
]
I delete the entries for .properties files because Groovy syntax is so much more flexible, but use them if you like. I also keep the dev files in the project root (and exclude from source control).
So when deploying, name the file correctly (different apps will have different files, so no clashing there) and put them in Tomcat's lib directory. This is in the classpath, and so the classpath: entry will see it.

specify env settings in command line

I have a node that runs several applications. These applications each have specific env settings. When I generate a release I start my node by just running ./rel/mynode/bin/mynode start. Is there an option that I could add to this command to override apps' env settings?
To answer your question: No, there is no parameter that you can pass into that command to load a different application env file.
However, if you are trying to load a different config file, for example a development file vs. a production file, you should check out how to do dynamic configuration with rebar.
I use it for running my application between different configured environments (production, and local testing).
I don't quite get what you mean by env settings. If you mean the applications configuration parameters that are set in the {Par,Val} tuples of the key env in the .app files then these can also be overridden in a system configuration file or directly in the command line. See the Configuring an Application section.
