Are there any logs? from Azure

ItsurranOP•2w ago

ive been sitting on this for 4 days 😂

dan1st•2w ago

And is /health a custom endpoint? Because the actuator one is normally/actuator/health

ItsurranOP•2w ago

is it this hard to deploy a backend 😂 yh /health is a custom endpoint i created

dan1st•2w ago

any logs after that? also maybe fix the warning

ItsurranOP•2w ago

all the same

dan1st•2w ago

How is the application deployed? Can you show your pom.xml?

ItsurranOP•2w ago

dan1st•2w ago

yes

dan1st•2w ago

If you remove the <version> from the Netty dependency, does your project still build?

ItsurranOP•2w ago

i just added it to se if it helps with the warning in my logs

dan1st•2w ago

so you added the version?

ItsurranOP•2w ago

the whole dependecy it wasnt there then i did nvm clean isntall and now pushing it to github actions to redeploy

dan1st•2w ago

Can you remove netty temporarily and run mvn dependency:tree? that should show you information on what uses netty/where it comes from

ItsurranOP•2w ago

removed the whole netty and did the command

dan1st•2w ago

Is there anything above that? especially something mentioning netty

ItsurranOP•2w ago

yep thats it

dan1st•2w ago

anything else mentioning netty in that list?

ItsurranOP•2w ago

nop thats all but that wouldnt fix the issue though right

ItsurranOP•2w ago

still get the warn

dan1st•2w ago

Can you switch to web server logs?

ItsurranOP•2w ago

even my postman when i try to hit the endpint its just loading and giving 503

ItsurranOP•2w ago

dan1st•2w ago

ItsurranOP•2w ago

sec

dan1st•2w ago

it kinda looks like there should be more

ItsurranOP•2w ago

im so confused

dan1st•2w ago

How are you deploying the app? that one looks like there should be more mentioning netty

ItsurranOP•2w ago

github actions with .jar

dan1st•2w ago

Can you show it?

ItsurranOP•2w ago

dan1st•2w ago

Can you run the application with java -jar locally?

ItsurranOP•2w ago

ah wait my appliaction was running

ItsurranOP•2w ago

dan1st•2w ago

Are you following a tutorial?

ItsurranOP•2w ago

atm no i did in the beginning but now its been 4 days i cant get this done 😭

dan1st•2w ago

Did you specify the port of your application in Azure?

ItsurranOP•2w ago

dan1st•2w ago

Like how should Azure know which port to use?

ItsurranOP•2w ago

true So do i add it in azure env or in my applaiction.properties

dan1st•2w ago

Do you have an Azure publish profile?

ItsurranOP•2w ago

yes wait nnmv

ItsurranOP•2w ago

dan1st•2w ago

Are there settings related to that?

ItsurranOP•2w ago

mby here?

dan1st•2w ago

You have an azure dependency - can you update that?

ItsurranOP•2w ago

what was the command to update all dependecies again in intellij also thats storage anyways

dan1st•2w ago

mvn versions:use-latest-versions that one?

dan1st•2w ago

also you might want to use Azure Spring Apps? https://learn.microsoft.com/en-us/azure/spring-apps/basic-standard/how-to-github-actions?pivots=programming-language-java

Use Azure Spring Apps CI/CD with GitHub Actions

How to build up a CI/CD workflow for Azure Spring Apps with GitHub Actions

ItsurranOP•2w ago

azure already provides that and created then

maybe you want to check the answers to https://stackoverflow.com/q/55354045/10871900, especially the one about networking

Azure web app is 503 Service Unavailable. How do I get it back runn...

Our website has been hosted on Azure for a few years. Tonight it is throwing 503 Service unavailable errors. I cannot even load a url to a .jpg file. I have restarted the app and still nothing load...

dan1st•2w ago

What does the "diagnose and solve problems" thing show?

ItsurranOP•2w ago

dan1st•2w ago

ok idk about that The app service logs there also doesn't have anything useful?

ItsurranOP•2w ago

literally nothing useful like wtf can it be

dan1st•2w ago

Is there a monitoring > metrics thing?

ItsurranOP•2w ago

sec'

ItsurranOP•2w ago

what metric should i show

dan1st•2w ago

cpu or memory also other thing to check: Is there a configuration > general > always on setting?

ItsurranOP•2w ago

yes

ItsurranOP•2w ago

dan1st•2w ago

can you show it? seems like the application is doing something

ItsurranOP•2w ago

dan1st•2w ago

I don't see an always on setting there?

ItsurranOP•2w ago

ah no alwqays on setting

ItsurranOP•2w ago

you mean this?

dan1st•2w ago

ok yes seems fine

ItsurranOP•2w ago

haha bro im telling you

dan1st•2w ago

Can you go to the console?

ItsurranOP•2w ago

dan1st•2w ago

uhh Windows Can you run netstat to see open ports? Is 8080 among them?

ItsurranOP•2w ago

yes

dan1st•2w ago

... Can you make an http request there? Is curl or Invoke-WebRequest available? you might need to allow networking somewhere

ItsurranOP•2w ago

dan1st•2w ago

Is that possible? from the console

ItsurranOP•2w ago

yes curl

dan1st•2w ago

Can you do curl http://localhost:8080 in the server console?

ItsurranOP•2w ago

dan1st•2w ago

so assuming it is running there, it isn't running on port 8080

ItsurranOP•2w ago

yes

dan1st•2w ago

Are you using the azure aervice blob for anything?

ItsurranOP•2w ago

yes

dan1st•2w ago

Did you update it before?

ItsurranOP•2w ago

how do you mean

dan1st•2w ago

What version of Spring Boot are you using?

ItsurranOP•2w ago

17 <java.version>17</java.version>

dan1st•2w ago

that's a Java version, not a Spring Boot version

ItsurranOP•2w ago

where do i check the spring boot version <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>3.4.0</version> <relativePath/>  </parent>

dan1st•2w ago

ItsurranOP•2w ago

good? should i push to github?

dan1st•2w ago

yes, try it

ItsurranOP•2w ago

What would you suspect the issue is

dan1st•2w ago

and in the thing where you got cpu and memory metrics, maybe there's also a requests metric azure gettkng the request but it not getting passed to the application in some way

ItsurranOP•2w ago

dan1st•2w ago

you could also try going to the console and typing ls to see what's in that directory Is there more information on these things? Like failing requests?

ItsurranOP•2w ago

dan1st•2w ago

Whag does "Service health" show on the left? doesn't look useful

ItsurranOP•2w ago

wait app.jar?

ItsurranOP•2w ago

thats not my jar

dan1st•2w ago

Can you run java -jar app.jar just to see what happens? maybe they just renamed it?

ItsurranOP•2w ago

na i remember i put that 4 days ago manually but i never used that

ItsurranOP•2w ago

this is my jar rn

dan1st•2w ago

oh ok then it's probably not the real one

ItsurranOP•2w ago

hmm fk i dont remeber how i put that in there

dan1st•2w ago

doesn't matter maybe you can establish a direct remote connection to your app from your machine?

dan1st•2w ago

for example like steps 2 and 3 in https://stackoverflow.com/a/71093211/10871900 but fir port 8080

How to remote debug a java application running on Azure App Service

When browsing to Settings > Configuration > General Settings Microsoft is pretty clear in that it currently doesn't support remote debugging (Linux App Service Plan, Java 11 SE). However, I ...

ItsurranOP•2w ago

dont get it

ItsurranOP•2w ago

What should i do :/

ItsurranOP•2w ago

now i get this @dan1st | Daniel

dan1st•2w ago

oh, interesting can you check the logs?

ItsurranOP•2w ago

still same

dan1st•2w ago

that looks like it at least received some response now Can you maybe increase the logging level and restart the application? Are you getting the exact same error about netty you got before?

ItsurranOP•2w ago

yep

dan1st•2w ago

with the exact same version numbers?

ItsurranOP•2w ago

this

dan1st•2w ago

this does look ok

ItsurranOP•2w ago

im trying something new in my securityconfig i let only localhost5173 t allow orgins mabe it can be that idk

dan1st•2w ago

How did you increase the log level?

ItsurranOP•2w ago

dan1st•2w ago

you could also try deploying without GitHub Actions if applicable

ItsurranOP•2w ago

should i try with docker

dan1st•2w ago

change the level from error to info or similar and you can change the log level for Spring via environment variables

ItsurranOP•2w ago

in my application.properties?

dan1st•2w ago

either there with e.g. logging.level.ROOT=DEBUG or with an environment variable like LOGGING_LEVEL_ROOT set to DEBUG

ItsurranOP•2w ago

now its back to

dan1st•2w ago

Did you change the logging level? tbh you could try if you did, check the logs again

ItsurranOP•2w ago

sry had to take a break this shit is giving me im gonna try with docker when i try with container it costs like 300$/m wtf @dan1st | Daniel

ItsurranOP•2w ago

so container worked
