QUESTION
In Quarkus, to include random files as classpath resource, we use quarkus.native.resources.includes (https://quarkus.io/guides/writing-native-applications-tips#including-resources).
How to include files in the file system? I.e. something read using new File(thePath).
If we use Jib, we simply put those files inside src/main/jib. But that's for non-native.
ANSWER
Answered 2022-Apr-08 at 06:02Building a native binary has nothing to do with adding files to the file system of the target platform.
If your goal is to create a container image using the native binary and also add files to the container image's filesystem, then you can use Quarkus with Jib and the files to src/main/jib (as you mentioned). These files will be included on the built container image as described here.

I am planning to use gradle as build tool with docker for containerizing spring boot applications.
I currently have one question regarding best practices/pros/cons from:
a. from general perspective as a best practice.
b. from CI /CD perspective.
I have understood that I can do it in three ways:
1. Do gradle build by running command on your host machine + then dockerize your spring boot appeg:
...ANSWER
Answered 2022-Mar-31 at 18:39After almost 7 years of building Docker images from Gradle, long before Docker became a commonplace thing, I’ve never done option 2. I’ve done options 1 and 3, primarily 3.
The problem with #1 is that you lose the information from your Gradle project that can be used to build the image, like the location of the jar file and the project name (there are several others). You end up redefining them on the command line, and the result could be very different.
The problem with #2 is the loss of developer productivity and conflating responsibilities. I can’t imagine building a Docker image every time I made a change to the code. Gradle is a build tool, Docker is a delivery mechanism, and they have different goals.
There are many articles that you can find online for building Docker images that apply equally well to Spring applications. Most notably:
- Use layers to avoid rebuilding code not changed.
- Use a Gradle Docker plugin to integrate Docker build within Gradle. I’m not sure if the Spring Boot plugin has integrated Docker build task now, if so, use that.
- Use a JRE as base instead of JDK if your code can live with that. Many projects don’t need JDK to run.
QUESTION
We are building an app based on Red Hat JBoss AMQ 6. We wrap some Java code around the base image to provide extra functionalities which are lacking in AMQ 6.
Now, when the CVE of Log4j stroke, we found that this component is vulnerable because it uses log4j 1.x. Now I don't just mean our Java code uses it, but also the base image of Red Hat AMQ 6 uses it. As AMQ 6 is EOL now, Red Hat does not provide support anymore, so there will not be official releases with fix.
So, how do I remove vulnerable log4j 1.x classes from:
- my Java code
- the base image
?
I am building with jib maven plugin.
It seems mvn dependency:tree only gives info about our Java wrapper code, not about the base image. And I don't understand what does the "+" and "-" mean while it gives output like this:

...ANSWER
Answered 2022-Mar-16 at 14:38You can always set a custom entrypoint using . You can start a shell script, run a different program, etc. Sometimes, you may want to use the feature to copy a script (and give executable permissions to it).
See here for some ideas to run a shell script:
Another option is to define your own
to use a shell. (Therefore, you need a base image that includes a shell binary (such as/bin/bash). Note that the default base image prior to Jib 3.0 was Distroless and did not include a shell program. OTOH, Jib 3.0+ doesn't use Distroless.) In this method, you'll need to know the right Java runtime classpath and the main class to use in your JVM launch command. To help this, starting with Jib >= 3.1, Jib creates two JVM argument files inside a built image; they will hold, respectively, the classpath and the main class inside a built image.Knowing the entrypoint, you can write a shell script (
my-entrypoint.sh):

QUESTION
I am using Jib to pull a base image, add my wrapper java code to it, and build my image on top of that. Due to the widely known log4j CVE in December 2021, we are looking for a way to remove the vulnerable classes. (Now more CVEs are found in 2022, one of them has a score of 10.0, the highest possible. See https://www.cvedetails.com/vulnerability-list/vendor_id-45/product_id-37215/Apache-Log4j.html)
The base image is near EOL, so the provider answered that they would not release a new version; besides, log4j 1.x also reached EOL long before. But the current situation is that we have no plan of upgrading the base image to next version, so removing the classes seem to be the only way now.
The base image will use /opt/amq/bin/launch.sh as entrypoint. And I have found that I can use customized entrypoint to run a script before that, which removes the classes. Like /opt/amq/bin/my_script.sh, and in that I have run_fix.sh && /opt/amq/bin/launch.sh.
Then I realized that even this would work by mitigating the risk when the application is actually running, the vulnerability scan(part of security process) will still raise alarms while examining the image binary, as this is a static process done before the image is uploaded to the docker registry for production, way before actually running it. They can only be removed at the moment when the application runs, aka at runtime.
Can jib pre-process the base image while doing Maven build(mvn clean install -Pdocker-build) instead of only allowing it at runtime? According to what I have read, I understand it's a big NO, and there's no plugin for it yet.
ANSWER
Answered 2022-Feb-25 at 16:45By the design of container images, it is impossible for anyone or any tool to physically remove files from an already existing container image. Images are immutable. The best you can try is "mark deletion" with some special "whiteout" file (.wh.xyz), which a container runtime will hide the target files at runtime.
However, I am not sure if your vulnerability scanner will take the effect of whiteout files into account during scanning. Hopefully it does. If it doesn't, the only option I can think of is to re-create your own base image.
Take a look at this Stack Overflow answer for more details.
QUESTION
I've built a Quarkus 2.7.1 console application using picocli that includes several subcommands. I'd like to be able to run this application within a Kubernetes cluster and decide its arguments at run-time. This is so that I can use the same container image to run the application in different modes within the cluster.
To get things started I added the JIB extension and tried setting the arguments using a configuration value quarkus.jib.jvm-arguments. Unfortunately it seems like this configuration value is locked at build-time so I'm unable to update this at run-time.
Next I tried setting quarkus.args while using default settings for JIB. The configuration value documentation makes it sound general enough for the job but it doesn't seem to have an affect when the application is run in the container. Since most references to this configuration value in documentation are in the context of Dev Mode I'm wondering if this may be disabled outside of that.
How can I get this application running in a container image with its arguments decided at run-time?
...ANSWER
Answered 2022-Feb-16 at 16:11I was able to find a solution to the problem with a bit of experimenting this morning.
With the quarkus-container-image-docker extension (instead of quarkus.jib.jvm-arguments) I was able to take the template Dockerfile.jvm and extend it to pass through arguments to the CLI. The only line that needed changing was the ENTRYPOINT (details included in the snippet below). I changed the ENTRYPOINT form (from exec to shell) and added an environment variable as an argument to pass-through program arguments.

The container creation fails with the message "Error": "OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "/deployments/run-java.sh": stat /deployments/run-java.sh: no such file or directory: unknown",
The whole process works fine when I change the Quarkus version from 2.7.0.Final to 2.6.3.Final.
I am using jib to generate the image. Please let me know if I am missing anything.
...ANSWER
Answered 2022-Feb-14 at 06:46This is due to the change in base image that went in with Quarkus 2.7. See the relevant entry in the migration guide.
The new base image does not contain the /deployments/run-java.sh shell script.
You can go back to the base image used in previous Quarkus versions using quarkus.jib.base-jvm-image=fabric8/java-alpine-openjdk11-jre
