JAVA8 Alpine JRE and JDK image tags are broken since last update

[sachingharge]

Hi Team,

We are seeing below errors for JAVA8 Alpine JRE and JDK image tags.
/bin/sh: /app/start.sh: not found

Can you please look into this?
We have also noticed that jre-alpine tag is no more supported but still exist. Is there any plan to stop supporting this tag in future and should use version specific tags only like 8-jre-alpine

Are you referring to the java image tags, or the OpenJDK tags

[sachingharge]

I am referring to OpenJDK tags.

This might help with seeing the layout of OpenJDK and what is supported #272

OpenJDK 11 doesn't have Alpine support #212 (comment)
OpenJDK 12 dropped Alpine support #281
OpenJDK 13 does support Alpine http://jdk.java.net/13/

$ docker pull openjdk:13-alpine
13-alpine: Pulling from library/openjdk
Digest: sha256:3a99d04ea2b4114b57e710cab2560ed86d0629b241a77dea60f0df57704818d8
Status: Downloaded newer image for openjdk:13-alpine

Since OpenJDK 11+ is from Oracle; there aren't JRE versions, just JDK. But for 11 we still have the JRE variant which isn't from Oracle

As for your specific error /bin/sh: /app/start.sh: not found can you give all the commands you ran and any relevant contextual information or files for reproducing that

Here is the example Dockerfile for reference where we are getting error "/bin/sh: /app/start.sh: not found"
We are just copying jar file in /app and start.sh in /app.

FROM openjdk:8-jre-alpine

ADD build/libs /app
ADD docker-bin /app

RUN chown -R daemon:daemon /app && \
    chmod -R 0777 /app && \
    chmod 0500 /app/start.sh

EXPOSE 8080
WORKDIR /app
USER daemon

CMD /app/start.sh

If the shebang of your "start.sh" script is bash, that's a common cause of that error (the Alpine images don't include Bash).

Closing since this doesn't seem to be an issue with the image

If you have further questions you could try asking the Docker Community Forums, the Docker Community Slack, or Stack Overflow. Since these repositories are for issues with the image and not necessarily for questions of usability

Thanks for your reply and indeed start.sh script was having bash.

Another question, does 8-jre-alpine docker tag is deprecated for openjdk:jre-alpine?
