Hi, I trying to run spring boot from your examples with forked tomcat inside docker with latest build 17-crac+5, getting error on the attempt to checkout app, can you give any advice?

root@bacc339c8eaf:/# jcmd 9 JDK.checkpoint
9:
CR: Checkpoint ...
--------------------

        at java.base/jdk.crac.Core.checkpointRestoreInternal(Core.java:262)

Also output of criu check --all contains a lot of not supported and denied lines maybe it is the reason?

 ./criu check --all

Looks good but some kernel features are missing
which, depending on your process tree, may cause
dump or restore failure.

Could you post complete command line for the app. And dump4.log from the CRaC image directory.

I followed the article "How to Run a Java Application with CRaC in a Docker Container" to run the app with CRaC inside a Docker container. I repeated the entire process again to gather the most recent information.

My docker file looks like:

FROM ubuntu:20.04


ENV JAVA_HOME /opt/jdk
ENV PATH $JAVA_HOME/bin:$PATH

RUN apt-get update -y

ADD "https://github.com/CRaC/openjdk-builds/releases/download/17-crac%2B5/openjdk-17-crac+5_linux-x64.tar.gz" $JAVA_HOME/openjdk.tar.gz
RUN tar --extract --file $JAVA_HOME/openjdk.tar.gz --directory "$JAVA_HOME" --strip-components 1; rm $JAVA_HOME/openjdk.tar.gz;

RUN mkdir -p /opt/crac-files

COPY build/libs/crac_spring-0.0.1-SNAPSHOT.jar /opt/app/crac_spring-0.0.1-SNAPSHOT.jar

Then I launched container docker run -it --privileged --rm --name my_app_on_crac my_app_on_crac and inside it run
command java -XX:CRaCCheckpointTo=/opt/crac-files -jar crac_spring-0.0.1-SNAPSHOT.jar.
After that, I connected to it in another terminal and created a checkpoint using the command: jcmd 11 JDK.checkpoint(In this case PID was equal 11).

The application log shows the following:

2023-05-16T07:50:55.163Z  INFO 11 --- [           main] com.example.springboot.Application       : Started Application in 1.646 seconds (process running for 2.436)

JVM: invalid info for restore provided: queued code -1
An exception during a checkpoint operation:

get the same output with docker running with wsl2 backend

I have also had very similar output with the spring-boot example [https://github.com/CRaC/example-spring-boot/] using docker 4.19 running wsl2 backend (Windows 10 Pro).

My Dockerfile is slightly different:

FROM ubuntu:20.04

ENV JAVA_HOME /opt/jdk
ENV PATH $JAVA_HOME/bin:$PATH

RUN apt-get update -y

ADD "https://github.com/CRaC/openjdk-builds/releases/download/17-crac%2B5/openjdk-17-crac+5_linux-x64.tar.gz" $JAVA_HOME/openjdk.tar.gz
RUN cd /opt/; chmod +x $JAVA_HOME/openjdk.tar.gz; tar --extract --file $JAVA_HOME/openjdk.tar.gz --directory "$JAVA_HOME" --strip-components 1; rm $JAVA_HOME/openjdk.tar.gz;

RUN mkdir -p /opt/crac-files

COPY target/spring-boot-initial-0.0.1-SNAPSHOT.jar /opt/app/MY-APP.jar

The debugging guide recommends checking whether the SUID bit is set and the criu file is owned by the root user (which was mentioned in a comment to a similar issue yesterday), however when I run ls -la $JAVA_HOME/lib/criu in Powershell it seems (to me at least) that the permissions are correctly set according to the debugging guide:

CRIU

After having set/ confirmed the SUID bit and criu ownership details I ran the application and attempted to create a checkpoint but ran into the same error:

CheckpointException

the output of the dump4.log file is

Could this issue be due to the chmod +x permissions for the jdk set in my Dockerfile?

I have also had very similar output with the spring-boot example [https://github.com/CRaC/example-spring-boot/] using docker 4.19 running wsl2 backend (Windows 10 Pro).

My Dockerfile is slightly different:

FROM ubuntu:20.04

ENV JAVA_HOME /opt/jdk
ENV PATH $JAVA_HOME/bin:$PATH

RUN apt-get update -y

ADD "https://github.com/CRaC/openjdk-builds/releases/download/17-crac%2B5/openjdk-17-crac+5_linux-x64.tar.gz" $JAVA_HOME/openjdk.tar.gz
RUN cd /opt/; chmod +x $JAVA_HOME/openjdk.tar.gz; tar --extract --file $JAVA_HOME/openjdk.tar.gz --directory "$JAVA_HOME" --strip-components 1; rm $JAVA_HOME/openjdk.tar.gz;

RUN mkdir -p /opt/crac-files

COPY target/spring-boot-initial-0.0.1-SNAPSHOT.jar /opt/app/MY-APP.jar

The debugging guide recommends checking whether the SUID bit is set and the criu file is owned by the root user (which was mentioned in a comment to a similar issue yesterday), however when I run ls -la $JAVA_HOME/lib/criu in Powershell it seems (to me at least) that the permissions are correctly set according to the debugging guide:

CRIU

After having set/ confirmed the SUID bit and criu ownership details I ran the application and attempted to create a checkpoint but ran into the same error:

CheckpointException

the output of the dump4.log file is

Could this issue be due to the chmod +x permissions for the jdk set in my Dockerfile?

I manage to get it working by running as root in WSL, I tried making the container run in privileged mode, and to enable some specifics permissions and nothing worked, at least not in my combination of docker for windows + wsl2 docker backend

only running from the root in wsl allowed it to work correctly

Thanks for the all of the information! We'll look at the issue.

Hi,
For now as a workaround for the seccomp issue, you may want to use --security-opt seccomp=unconfined option when running a container.

One more thought.
I followed the article "How to Run a Java Application with CRaC in a Docker Container" with my home clean macbook and it works fine.
Looks like the initial issue was related with some kind of corporate policies.

The debugging guide recommends checking whether the SUID bit is set and the criu file is owned by the root user (which was mentioned in a comment to a similar issue yesterday), however when I run ls -la $JAVA_HOME/lib/criu in Powershell it seems (to me at least) that the permissions are correctly set according to the debugging guide:

CRIU

After having set/ confirmed the SUID bit and criu ownership details I ran the application and attempted to create a checkpoint but ran into the same error:

CheckpointException

the output of the dump4.log file is

Could this issue be due to the chmod +x permissions for the jdk set in my Dockerfile?

Since commenting, I have managed to successfully create and restore from a checkpoint using CRaC on a hosted VM so, from my side at least, this thread can be considered closed. Bottom line is to work in a linux dev environment where you have full control.
