Is it possible to customize Dropwizrd's healthcheck output so that, e.g.: /health for healthchecks instead of /healthcheck and some output like {“status”: 200}.
I realise I could simply write a new resource that does what ever I need, I was just wondering if there is a more standard way to do this.
From what I have read on the 0.7.1 source code it's not possible to change the resource URI for healthchecks unfortunately, I highly doubt you can change the healthcheck format. I also remember people complaining about not being able to add REST resources to admin page, only servlets. Maybe on 0.8.0?
Here are the details of what I've tracked so far on the source code. Maybe I have misread or misunderstood something, so somebody could fix it.
Metrics has actually written AdminServlet to add healtcheck servlet in a way that it checks the servlet config whether the URI is defined or not.
this.healthcheckUri = getParam(config.getInitParameter(HEALTHCHECK_URI_PARAM_KEY), DEFAULT_HEALTHCHECK_URI);
But dropwizard doesn't provide a way to inject this configuration in any way on AbstractServerFactory.
handler.addServlet(new NonblockingServletHolder(new AdminServlet()), "/*");
NonblockingServletHolder is the one which is providing the config to AdminServlet but is created by AbstractServerFactory with empty constructor and provides no way to change the config.
I've thought of and tried to access the ServletHolder from the Environment object on Application.run method but the admin servlets are not created until after run method is run.
environment.getAdminContext().getServletHandler().getServlets()[0].setInitParameter("healthcheck-uri", "/health");
Something like this in your run() function will help you control the URI of your healthchecks:
environment.servlets().addServlet(
"HealthCheckServlet",
new HealthCheckServlet(environment.healthChecks())
).addMapping("/health");
If you want to actually control what's returned you need to write your own resource file. Fetch all the healthchecks from the registery, run them and return whatever aggregated value you want based on their results.

The documentation only shows that you can pass the SystemConfigService as a parameter to another service.
Is there also the possibility to pass directly the value from the plugin configuration?
Background of the question: I would like to initialize directly an instance of an external component. But this expects fixed arguments as strings. Alternatively, one would otherwise have to write some kind of factory.
Hm, it's possible to do. I have not done this directly myself, but 99% confident that it will work. You may need to play around with it a little.
In the services.xml you can use symfony expressions.
<argument type="expression">service('Shopware\Core\System\SystemConfig\SystemConfigService').get('SwagBasicExample.config.example')</argument>
You may need to find the alias name for the Shopware\Core\System\SystemConfig\SystemConfigService class instead. Also check the Symfony documentation, you can do a lot more with this!
I myself passed an array as an argument, but used a custom class as a config getter like so:
<argument type="expression">
{
"shop_is_active": service('config_bridge').get('isActive'),
"customer_number": service('config_bridge').get('customerNumber'),
"shop_number": service('config_bridge').get('shopNumber'),
"apikey": service('config_bridge').get('apiKey')
}
</argument>
Not strictly necessary as Shopware already requires it, but always a good practice to add the requirement to your plugin composer file:
"require": {
...,
"symfony/expression-language": "~5.3.0|~5.4.0"
},
As of today it's not possible to inject specific system_config values in services.
I want to get access to external YAML file which I specify through command-line argument:
java -jar target/app-thorntail.jar -s./test.yaml
This file I need to use to get my custom properties tree by SnakeYaml.
You can use #Inject #ConfigurationValue for your custom properties, and you can #Inject a ConfigView to read the entire configuration tree. I believe that should be enough for your usecase. This approach will also provide correct values in case multiple configuration files are used.
I'm not sure if you can get access to the file itself, except maybe provide a custom main method and parse the command-line arguments yourself.
I have been triggering google dataflow templates through endpoints. Now, I want to pass some input to the dataflow template through these endpoints. These inputs are custom made e.g the name of the output file. I have been around valueProviders, would these help in this context?
ValueProviders is the way to add template support to a parameter.
If you want to be able to provide a runtime option for a job, you first need to define that ValueProvider in your user code:
https://cloud.google.com/dataflow/docs/templates/creating-templates
Once you do that, you'll be able to run the job providing a runtime value for the specific parameter:
https://cloud.google.com/dataflow/docs/templates/executing-templates
Yes, Value Providers helps in taking runtime params. Although, you would need to make some stub call to expose the custom params otherwise dataflow jobs would not take the param as input. Hope it helps to others as well.
I'm currently mapping my ZF1 applications to ZF2 and was wondering if there is a similar function like $this->view->getScriptPath() from ZF1 in ZF2? I spend already my half day, but didn't find a good solution. It would also be fine to get at least the basePath of the Module or the template folder of the Module.
Based on the follow-up questions, what you are really looking for is the path to a given template file. This is actually relatively easy, assuming you're using the default PhpRenderer: you grab the resolver, and resolve the path.
If you're inside a view script already, the following should work:
$path = $this->resolver($templateName);
If you're elsewhere, you need access to either the PhpRenderer, or the ViewResolver. If you have access to the service manager, pull the ViewResolver service, and call resolve() on it:
$resolver = $services->get('ViewResolver');
$path = $resolver->resolve($templateName);
This is superior to knowing where the module lives, as the developer may have chosen to override the template within the application; the resolver will know where even the new location is.
I have a question about ruby and wsdl soap.
I couldn't find a way to get each method's params and their type.
For example, if I found out that a soap has a methods called "get_user_information" (using wsdlDriver) is there a way to know if this method requires some params and what type of params does it require (int, string, complex type, ecc..)?
I'd like to be able to build html forms from a remote wsdl for each method...
Sorry for my horrible English :D
Are you using soapr4?
Soap4r comes with a command line client to build proxies for accessing web services via SOAP. This is preferable to using the wsdlDriver which has to build the proxy dynamically every time it runs.
To build a "permanent" proxy then you need to run the following command
wsdl2ruby.rb --type client --wsdl http://some/path/to/the/wsdl
When this command runs then you should end up with a bunch of ruby files one of which (probably default.rb) will call each method in turn and document the necessary inputs and outputs.
Alternatively you may find the Wsdl Analyser useful. This will allow you to enter the URL for a WSDL which it will then analyse and list all of the operations and (sometimes) the paramaters required
Thank you for the very quick response!
I'll try to explain myself a little better :D
I've tried soap4r, and I'm able to get soap's methods with something like this:
require "soap/wsdlDriver"
client = SOAP::WSDLDriverFactory.new(my-wsdl-url).create_rpc_driver
puts client.singleton_methods
What I'd like to know is:
If, for example, my soap has a method called "get_some_params_and_sum_them", is there a way to know how many params it takes and which type they should be?
Something like
puts client.method("get_some_params_and_sum_them").params
Wsdl Analyser does it, and I'd like to know if this is possible also in a ruby script without tons of code lines :D
