##### This Dockerfile is used in order to build a container that runs the Quarkus application in JVM mode## Before building the container image run:## ./gradlew build## Then, build the image with:## docker build -f src/main/docker/Dockerfile.jvm -t quarkus/basic-java-jvm .## Then run the container using:## docker run -i --rm -p 8080:8080 quarkus/basic-java-jvm## If you want to include the debug port into your docker image# you will have to expose the debug port (default 5005 being the default) like this : EXPOSE 8080 5005.# Additionally you will have to set -e JAVA_DEBUG=true and -e JAVA_DEBUG_PORT=*:5005# when running the container## Then run the container using :## docker run -i --rm -p 8080:8080 quarkus/basic-java-jvm## This image uses the `run-java.sh` script to run the application.# This scripts computes the command line to execute your Java application, and# includes memory/GC tuning.# You can configure the behavior using the following environment properties:# - JAVA_OPTS: JVM options passed to the `java` command (example: "-verbose:class")# - JAVA_OPTS_APPEND: User specified Java options to be appended to generated options# in JAVA_OPTS (example: "-Dsome.property=foo")# - JAVA_MAX_MEM_RATIO: Is used when no `-Xmx` option is given in JAVA_OPTS. This is# used to calculate a default maximal heap memory based on a containers restriction.# If used in a container without any memory constraints for the container then this# option has no effect. If there is a memory constraint then `-Xmx` is set to a ratio# of the container available memory as set here. The default is `50` which means 50%# of the available memory is used as an upper boundary. You can skip this mechanism by# setting this value to `0` in which case no `-Xmx` option is added.# - JAVA_INITIAL_MEM_RATIO: Is used when no `-Xms` option is given in JAVA_OPTS. This# is used to calculate a default initial heap memory based on the maximum heap memory.# If used in a container without any memory constraints for the container then this# option has no effect. If there is a memory constraint then `-Xms` is set to a ratio# of the `-Xmx` memory as set here. The default is `25` which means 25% of the `-Xmx`# is used as the initial heap size. You can skip this mechanism by setting this value# to `0` in which case no `-Xms` option is added (example: "25")# - JAVA_MAX_INITIAL_MEM: Is used when no `-Xms` option is given in JAVA_OPTS.# This is used to calculate the maximum value of the initial heap memory. If used in# a container without any memory constraints for the container then this option has# no effect. If there is a memory constraint then `-Xms` is limited to the value set# here. The default is 4096MB which means the calculated value of `-Xms` never will# be greater than 4096MB. The value of this variable is expressed in MB (example: "4096")# - JAVA_DIAGNOSTICS: Set this to get some diagnostics information to standard output# when things are happening. This option, if set to true, will set# `-XX:+UnlockDiagnosticVMOptions`. Disabled by default (example: "true").# - JAVA_DEBUG: If set remote debugging will be switched on. Disabled by default (example:# true").# - JAVA_DEBUG_PORT: Port used for remote debugging. Defaults to 5005 (example: "8787").# - CONTAINER_CORE_LIMIT: A calculated core limit as described in# https://www.kernel.org/doc/Documentation/scheduler/sched-bwc.txt. (example: "2")# - CONTAINER_MAX_MEMORY: Memory limit given to the container (example: "1024").# - GC_MIN_HEAP_FREE_RATIO: Minimum percentage of heap free after GC to avoid expansion.# (example: "20")# - GC_MAX_HEAP_FREE_RATIO: Maximum percentage of heap free after GC to avoid shrinking.# (example: "40")# - GC_TIME_RATIO: Specifies the ratio of the time spent outside the garbage collection.# (example: "4")# - GC_ADAPTIVE_SIZE_POLICY_WEIGHT: The weighting given to the current GC time versus# previous GC times. (example: "90")# - GC_METASPACE_SIZE: The initial metaspace size. (example: "20")# - GC_MAX_METASPACE_SIZE: The maximum metaspace size. (example: "100")# - GC_CONTAINER_OPTIONS: Specify Java GC to use. The value of this variable should# contain the necessary JRE command-line options to specify the required GC, which# will override the default of `-XX:+UseParallelGC` (example: -XX:+UseG1GC).# - HTTPS_PROXY: The location of the https proxy. (example: "myuser@127.0.0.1:8080")# - HTTP_PROXY: The location of the http proxy. (example: "myuser@127.0.0.1:8080")# - NO_PROXY: A comma separated lists of hosts, IP addresses or domains that can be# accessed directly. (example: "foo.example.com,bar.example.com")####FROM registry.access.redhat.com/ubi8/openjdk-21:1.18ENV LANGUAGE='en_US:en'# We make four distinct layers so if there are application changes the library layers can be re-usedCOPY --chown=185 build/quarkus-app/lib/ /deployments/lib/COPY --chown=185 build/quarkus-app/*.jar /deployments/COPY --chown=185 build/quarkus-app/app/ /deployments/app/COPY --chown=185 build/quarkus-app/quarkus/ /deployments/quarkus/EXPOSE 8080USER 185ENV JAVA_OPTS_APPEND="-Dquarkus.http.host=0.0.0.0 -Djava.util.logging.manager=org.jboss.logmanager.LogManager"ENV JAVA_APP_JAR="/deployments/quarkus-run.jar"ENTRYPOINT [ "/opt/jboss/container/java/run/run-java.sh" ]
