+# myapp
+
+This project uses Quarkus, the Supersonic Subatomic Java Framework.
+
+If you want to learn more about Quarkus, please visit its website: https://quarkus.io/ .
+
+## Running the application in dev mode
+
+You can run your application in dev mode that enables live coding using:
+```shell script
+./mvnw compile quarkus:dev
+```
+
+> **_NOTE:_** Quarkus now ships with a Dev UI, which is available in dev mode only at http://localhost:8080/q/dev/.
+
+## Packaging and running the application
+
+The application can be packaged using:
+```shell script
+./mvnw package
+```
+It produces the `quarkus-run.jar` file in the `target/quarkus-app/` directory.
+Be aware that it’s not an _über-jar_ as the dependencies are copied into the `target/quarkus-app/lib/` directory.
+
+The application is now runnable using `java -jar target/quarkus-app/quarkus-run.jar`.
+
+If you want to build an _über-jar_, execute the following command:
+```shell script
+./mvnw package -Dquarkus.package.type=uber-jar
+```
+
+The application, packaged as an _über-jar_, is now runnable using `java -jar target/*-runner.jar`.
+
+## Creating a native executable
+
+You can create a native executable using:
+```shell script
+./mvnw package -Dnative
+```
+
+Or, if you don't have GraalVM installed, you can run the native executable build in a container using:
+```shell script
+./mvnw package -Dnative -Dquarkus.native.container-build=true
+```
+
+You can then execute your native executable with: `./target/myapp-0.1.0-runner`
+
+If you want to learn more about building native executables, please consult https://quarkus.io/guides/maven-tooling.
+

+# docker build -f src/main/docker/Dockerfile.jvm -t quarkus/myapp-jvm .

+#
+# docker run -i --rm -p 8080:8080 quarkus/myapp-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/myapp-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

+# - HTTPS_PROXY: The location of the https proxy. (example: "myuser@127.0.0.1:8080")
