Docker: problem with run a file jar in docker

271 Views Asked by Antonio Romano At 17 April 2025 at 17:56

I'm new in the community and i'm new in docker's world. i have to virtualize a leshan server through docker and I have to do this with the option "--redis" that leshan makes avaible. so I decided to take a dockerfile from docker hub and modify the last "CMD" operation adding the option "--redis". The Build of images is successful but when i try to run the image in a container the error is "Invalid or corrupt jarfile". This problem show up also without the option "--redis" (with the no modify dockerfile). The strange thing is that if I pull the image from dockerhub and run the server build through same dockerfile, it works!

This is the docker file:

FROM linarotechnologies/alpine:edge

RUN apk add --no-cache openjdk8-jre-base ca-certificates shadow curl
runit

RUN mkdir -p /opt/leshan-server-demo && \
    curl -o /opt/leshan-server-demo/leshan-server-demo.jar \
    https://hudson.eclipse.org/leshan/job/leshan/lastSuccessfulBuild/artifact/leshan-server-demo.jar
RUN useradd -r -d /opt/leshan-server-demo -s /sbin/nologin -U leshan

CMD cd /tmp && chpst -u leshan java -jar /opt/leshan-server-demo/leshan-server-demo.jar $LESHAN_ARGS

this is the build:

 ---> 68acab7c306e
Successfully built 68acab7c306e
Successfully tagged leshan-server:latest

And this is the error when i run:

sudo docker run --rm -ti --name leshan-server leshan-server Error: Invalid or corrupt jarfile /opt/leshan-server-demo/leshan-server-demo.jar

Any ideas? Thank you for help!

https://hudson.eclipse.org/leshan/job/leshan/lastSuccessfulBuild/artifact/leshan-server-demo.jar

This url has redirect with 302. You have to use -L parameter with curl to follow the link.

~# curl -o test.jar https://hudson.eclipse.org/leshan/job/leshan/lastSuccessfulBuild/artifact/leshan-server-demo.jar

~# cat leshan-server-demo.jar
<html>
<head><title>302 Found</title></head>
<body>
<center><h1>302 Found</h1></center>
<hr><center>nginx</center>
</body>
</html>

curl is downloading the html redirect page.

You can tell curl to follow the redirects using -L option.

/opt/leshan-server-demo # curl -L -o test.jar https://hudson.eclipse.org/leshan/job/leshan/lastSuccessfulBuild/artifact/leshan-server-demo.
