Remote debug not working #23765

edeandrea · 2022-02-16T15:04:51Z

I used the openshift extension to deploy my app to OpenShift via an S2I binary build. The app is up and running and quarkus:remote-dev connects to it fine and any local changes are pushed/reflected as expected.

My challenge is I can't seem to connect a remote debugger to it. I can't seem to get the pod to run in debug.

I've tried lots of combinations of environment variables/arguments, but nothing works. Here's what I've tried:

set env var JAVA_DEBUG=true
set property quarkus.openshift.jvm-arguments=-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005
set property quarkus.openshift.jvm-arguments=-Ddebug=true

The Quarkus OpenShift config says that the base jvm image is registry.access.redhat.com/ubi8/openjdk-11. When looking at the documentation for the image I should just be able to set JAVA_DEBUG=true and it should work, but it doesn't seem to be.

Is this a Quarkus issue? An issue with the openjdk-11 image?

Is this a Quarkus issue?

It can't be as Quarkus has nothing to do with JVM debugging.

set env var JAVA_DEBUG=true

How were you setting this?

In any case, you'll need to see what the configuration of the running Pod is to see what environment variables and/or arguments are set.
Another thing to check is to see exec into the the running container and find the actual java ... command that launched the application.

It can't be as Quarkus has nothing to do with JVM debugging.

But the Dockerfile.jvm that was used to create the image (https://github.com/quarkusio/quarkus-super-heroes/blob/main/rest-villains/src/main/docker/Dockerfile.jvm) came from code.quarkus.io. That Dockerfile defines its own ENTRYPOINT which does not include any debug "stuff".

set env var JAVA_DEBUG=true

How were you setting this?

By adding the environment variable to the DeploymentConfig and then triggering a rollout

In any case, you'll need to see what the configuration of the running Pod is to see what environment variables and/or arguments are set. Another thing to check is to see exec into the the running container and find the actual java ... command that launched the application.

It seems the image used (ubi8/openjdk-11-runtime) doesn't have any kind of cli tools installed (no ps nor lsof), so I'm not sure how to see what the actual java process looks like, although looking at the ENTRYPOINT I would suspect it is simply java -jar.

If I then push the app directly to OpenShift using the Quarkus openshift extension it seems to use the ubi8/openjdk-11 image. If you look at the documentation it mentions the whole JAVA_DEBUG thing.

I do not see the Listening for transport dt_socket at address message in the pod startup.

When I follow the instructions in that guide for the OpenJDK image with the example it uses everything works fine, so something in the ./mvnw package -Dquarkus.kubernetes.deploy=true isn't working the way it should.

Not sure if its helpful, but here's the s2i build log:

But the Dockerfile.jvm that was used to create the image (https://github.com/quarkusio/quarkus-super-heroes/blob/main/rest-villains/src/main/docker/Dockerfile.jvm) came from code.quarkus.io. That Dockerfile defines its own ENTRYPOINT which does not include any debug "stuff".

You never mentioned you were using the Dockerfile...

It seems the image used (ubi8/openjdk-11-runtime) doesn't have any kind of cli tools installed (no ps nor lsof), so I'm not sure how to see what the actual java process looks like, although looking at the ENTRYPOINT I would suspect it is simply java -jar.

Does it comes with jcmd in the directory where java is found? If so, you can do things like:

jcmd <pid> VM.flags
jcmd <pid> VM.command_line

edeandrea · 2022-02-17T14:09:05Z

You never mentioned you were using the Dockerfile...

That's what I tried first, just deploying the image that was built with that Dockerfile. When that didn't work I switched back to the s2i binary build, deploying from my local machine.

Does it comes with jcmd in the directory where java is found? If so, you can do things like:

It does have jcmd but I don't know what the pid is....

If you look at the DeplopymentConfig that was generated by the openshift extension (see the end of my previous comment), take note of the command - it completely skips/ignores/bypasses the run-java.sh script that is included in the base image (which respects the JAVA_DEBUG flag)

edeandrea · 2022-02-17T14:11:47Z

Note - if I manually go into the DeploymentConfig and alter the command by adding -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005 and trigger a rollout, it then works.

Doing -Dquarkus.openshift.jvm-arguments=-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005 when running the ./mvnw package ... does not work though. I would have expected it to.

geoand · 2022-02-17T14:12:13Z

It does have jcmd but I don't know what the pid is....

jps should give it you

geoand · 2022-02-17T14:18:56Z

One question, where does quarkus.openshift.jvm-arguments come from? Is it mentioned somewhere in the docs?
Have you tried quarkus.openshift.arguments=-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005 instead?

edeandrea · 2022-02-17T14:25:59Z

In fact, if I run ./mvnw clean package -DskipTests -Dquarkus.kubernetes.deployment-target=openshift -Dquarkus.container-image.builder=openshift -Dquarkus.openshift.resources.limits.memory=768Mi -Dquarkus.openshift.resources.requests.memory=256Mi -Dquarkus.kubernetes.deploy=true -Dquarkus.openshift.env.vars.JAVA_DEBUG=true -Dquarkus.container-image.build=true -Dquarkus.openshift.jvm-arguments="-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005" the Pod fails to even start. It gives a message

ERROR: JDWP Non-server transport dt_socket must have a connection address specified through the 'address=' option
ERROR: JDWP invalid option: -agentlib:jdwp=transport=dt_socket

If I look. at the command in the DeploymentConfig that was deployed, I see

command:
  - java 
  - '-agentlib:jdwp=transport=dt_socket'
  - server=y
  - suspend=n
  - 'address=*:5005'
  - '-jar'
  - /deployments/quarkus-run.jar

It looks like because the argument has commas in it, its getting separated into separate arguments. If I (manually) change the command to be

command:
  - java 
  - '-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005'
  - '-jar'
  - /deployments/quarkus-run.jar

then it works

One question, where does quarkus.openshift.jvm-arguments come from?

https://quarkus.io/guides/all-config#quarkus-container-image-openshift_quarkus.openshift.jvm-arguments

Have you tried quarkus.openshift.arguments=-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005 instead?

Has no effect whatsoever

geoand · 2022-02-17T14:35:48Z

@iocanel when I set quarkus.openshift.arguments=-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005,
then

        args:
            - -agentlib:jdwp=transport=dt_socket
            - server=y
            - suspend=n
            - address=*:5005

is added to the container instead of appended to the command (the code that is responsible is in KubernetesCommonHelder#createArgsDecorator).
That seems incorrect, no? If it's not, I can fix it

edeandrea · 2022-02-17T14:41:39Z

I guess in addition was not using the provided run script (which handles the presence of the JAVA_DEBUG environment variable) a conscious decision by Quarkus? It seems when the openshift extension generates the DeploymentConfig it is overriding the command from the base image.

Was that a conscious choice? If so, why?

geoand · 2022-02-17T14:43:14Z

Was that a conscious choice? If so, why?

I am not privy to this, it's up to @iocanel to answer

edeandrea · 2022-02-22T20:10:06Z

This looks like its been resolved now.

The DeploymentConfig no longer specified the command.

The latest code.quarkus.io also generates a different Dockerfile - one that's based on the OpenJDK image and does not override the ENTRYPOINT.

geoand · 2022-02-23T04:17:57Z

Good to know!

edeandrea · 2022-02-23T13:32:12Z

Actually I'm going to re-open this as only part of the issue seems to have been resolved. Now that theDockerfile.jvm references the OpenJDK image and doesn't override the ENTRYPOINT, deploying an image I build using the docker extension and setting JAVA_DEBUG=true works.

What seems broken is if I am generating resources and/or deploying via the openshift extension.

In https://github.com/quarkusio/quarkus-super-heroes/tree/main/rest-villains If I run

./mvnw clean package -DskipTests \
  -Dquarkus.kubernetes.deployment-target=openshift \
  -Dquarkus.container-image.builder=openshift \
  -Dquarkus.openshift.resources.limits.memory=768Mi \
  -Dquarkus.openshift.resources.requests.memory=256Mi \
  -Dquarkus.openshift.env.vars.JAVA_DEBUG=true

and then inspect the resulting target/kubernetes/openshift.yml I see that the app's DeploymentConfig looks like the following and the command is overridden.

In this scenario it is almost impossible to turn on remote debug unless I then go in and manually tweak the resulting DeploymentConfig. The DeploymentConfig already references the image (which is already set up for remote debug), so why the need to also specify a command?

Also, the imagePullPolicy doesn't seem to be respected. The docs say that the default value for quarkus.openshift.image-pull-policy (or quarkus.kubernetes.image-pull-policy) is Always, which doesn't seem to be the case, as below it shows IfNotPresent.

Default port env variable seems not correct. On my side I had to specify
JAVA_DEBUG_PORT=*:5005 instead of default 5005 to make it works.

Sgitario · 2022-03-29T12:14:51Z

@florentgarin do you mean that using the configuration in gsmet@67505dc#diff-352a260cfb79854020efe849e44cedb10355aa4bd7b5eed1db676b77d8870a86R14, didn't work for you?
For me, it's working fine tho. But it's also working fine with "*:5005".

florentgarin · 2022-03-29T12:50:05Z

No I mean that if you simply use the generated Dockerfile.jvm, build it with the docker command exactly as mentioned in the comments and run it (as explained, plain basic Docker style). Then you will not be able to remote debug your container without -e JAVA_DEBUG_PORT=*:5005
