# test-quarkus
|
||
|
||
This project uses Quarkus, the Supersonic Subatomic Java Framework.
|
||
|
||
If you want to learn more about Quarkus, please visit its website: https://quarkus.io/ .
|
||
|
||
## Building and deploying natively
|
||
|
||
Build the native image with the Mandrel-based multi-stage Dockerfile and push it
|
||
to a remote Docker host over an SSH tunnel. The script starts a temporary
|
||
`registry:2` container on the remote (localhost only), forwards it to the build
|
||
machine, pushes the image through that tunnel, then pulls and retags it on the
|
||
remote Docker daemon. No external registry is required.
|
||
|
||
```shell script
|
||
./scripts/build-and-push.sh --remote deploy@prod.example.com
|
||
```
|
||
|
||
The script reads `artifactId` and `version` from `pom.xml` for the image name
|
||
and version tag, builds for `linux/amd64`, and verifies the image is present on
|
||
the remote after pushing. On the remote (and locally) that push is tagged three
|
||
ways, all pointing at the same image:
|
||
|
||
- `<name>:<version>` — the version from `pom.xml` or `--tag`
|
||
- `<name>:latest` — moved to this push on every successful deploy
|
||
- `<name>:sha256-<12 hex chars>` — immutable tag taken from the registry digest
|
||
|
||
The temporary registry container and SSH tunnel are removed when the script
|
||
finishes. See `./scripts/build-and-push.sh --help` for all flags.
|
||
|
||
To remove leftover temporary registry containers and `localhost:<port>/...` image
|
||
tags on the remote (for example after an interrupted push or manual tests):
|
||
|
||
```shell script
|
||
./scripts/build-and-push.sh --remote deploy@prod.example.com --cleanup
|
||
```
|
||
|
||
This does not rebuild or push; it only needs SSH access to the remote host.
|
||
|
||
It can be invoked from any directory: by default it resolves the project root
|
||
from the script's own location. Override with `--project-dir PATH` or the
|
||
`PROJECT_DIR` environment variable when needed.
|
||
|
||
### SSH config aliases
|
||
|
||
`--remote` accepts either an explicit `user@host[:port]` or a bare alias that
|
||
is resolved from `~/.ssh/config`. The matching `Host` block supplies
|
||
`HostName`, `User`, `Port` and `IdentityFile` automatically:
|
||
|
||
```text
|
||
# ~/.ssh/config
|
||
Host prod
|
||
HostName prod.example.com
|
||
User deploy
|
||
Port 22
|
||
IdentityFile ~/.ssh/deploy_ed25519
|
||
```
|
||
|
||
```shell script
|
||
./scripts/build-and-push.sh --remote prod
|
||
# Resolves to deploy@prod.example.com:22 using ~/.ssh/deploy_ed25519
|
||
```
|
||
|
||
`--ssh-key` always overrides the config `IdentityFile`. Use `--ssh-config PATH`
|
||
to point at a non-default config file.
|
||
|
||
## 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/test-quarkus-1.0.0-SNAPSHOT-runner`
|
||
|
||
