Updating OpenJDK Version in an Older jboss/wildfly Docker Image

For TLSv1.3 support we need min Java 8u261-b12 version as discussed here.

How can we update Open JDK version to 8u lastest in an older Docker Image such as jboss/wildfly:10.1.0.Final?

Is there a best practice for that? My DockerFile starts like that:

FROM jboss/wildfly:10.1.0.Final
Solution

  • I download the jdk1.8.0_311 package an unzip it. With using COPY command I override the old JDK in the image with DockerFile, it worked!

    DockerFile

    FROM jboss/wildfly:10.1.0.Final

USER root
COPY JRE/* /usr/lib/jvm/java/
RUN chown -R root /usr/lib/jvm/java/
RUN chmod -R 775 /usr/lib/jvm/java/
