kandi X-RAY | jvmkill Summary
jvmkill is a simple JVMTI agent that forcibly terminates the JVM when it is unable to allocate memory or create a thread. This is important for reliability purposes: an OutOfMemoryError or thread creation failure will often leave the JVM in an inconsistent state. Terminating the JVM will allow it to be restarted by an external process manager. It is often useful to automatically dump the Java heap using the -XX:+HeapDumpOnOutOfMemoryError JVM argument. This agent will be notified and terminate the JVM after the heap dump completes.

QUESTION
I am pushing a minimalistic Spring Boot web application on Cloud Foundry. My manifest looks like
...ANSWER
Answered 2022-Jan-20 at 20:34Who is creating the process of type task
The buildpack creates both. This is what's been happening for a while, but recent cf cli changes are making this more visible.
What is the purpose of this process ?
I didn't add that into the buildpack so I can't 100% say its purpose, but I believe it is meant to be used in conjunction with running Java apps ask tasks on CF.
See this commit.
When you run a task, there is a --process
flag to the cf run-task
command which can be used to set a process to use as the command template. I believe the idea is that you'd set it to task
so it can use that command to run your ask. See here for reference to that flag.
QUESTION
I've got a problem with this integration. I use MongoDB based on docker without problems, but when I create a Docker Compose, the Spring Boot WebFlux stop to find the Mongo. I'm trying to find the problem, but I don't know how to solve it.
The service log shows me this problem:
...ANSWER
Answered 2021-Aug-05 at 15:30So what exactly is the problem here? Without knowing more about the application, I can't really tell why it's trying localhost
first, but it seems like it's able to connect to mongo running on the person-db
container after that based on these logs:
QUESTION
I am using spring-boot-maven-plugin to build a docker image from my app with this command:
...ANSWER
Answered 2021-Jan-13 at 21:46It depends on your goal here. It sounds like you want to change the max direct memory in your container when your app runs so you should be just doing what you indicated works here (and what's listed in the docs).
docker run -e JAVA_TOOL_OPTIONS=-XX:MaxDirectMemorySize=64M docker.io/example/app-name:0.0.1
The doc link you're referencing is talking about configuring options at runtime which is what you are doing with the env variables.
