# metrics-service
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 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.jar.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/metrics-service-1.0.0-SNAPSHOT-runner`
If you want to learn more about building native executables, please consult <https://quarkus.io/guides/maven-tooling>.

# This Dockerfile is used in order to build a container that runs the Quarkus application in JVM mode
#
# Before building the container image run:
#
# ./mvnw package
#
# Then, build the image with:
#
# docker build -f src/main/docker/Dockerfile.jvm -t quarkus/metrics-service-jvm .
#
# Then run the container using:
#
# docker run -i --rm -p 8080:8080 quarkus/metrics-service-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/metrics-service-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") - Be aware that this will override
# the default JVM options, use `JAVA_OPTS_APPEND` to append options
# - 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")
