To try the image, run the `java -version` command:
```bash
openjdk version "1.8.0_422"
OpenJDK Runtime Environment (IcedTea 3.32.0) (Alpine 8.422.05-r0)
OpenJDK 64-Bit Server VM (build 25.422-b05, mixed mode)
$ docker run --rm ghcr.io/openzipkin/java:8.432.06 -version
openjdk version "1.8.0_432"
OpenJDK Runtime Environment (IcedTea 3.33.0) (Alpine 8.432.06-r1)
OpenJDK 64-Bit Server VM (build 25.432-b06, mixed mode)
```

## Release process
Build the `Dockerfile` using the current version without the revision classifier from here:
* https://pkgs.alpinelinux.org/packages?name=openjdk8
```bash
# Note 8.422.05 not 8.422.05-r1!
./build-bin/build 8.422.05
# Note 8.432.06 not 8.432.06-r1!
./build-bin/build 8.432.06
```

Next, verify the built image matches that version:
```bash
openjdk version "1.8.0_422"
OpenJDK Runtime Environment (IcedTea 3.32.0) (Alpine 8.422.05-r0)
OpenJDK 64-Bit Server VM (build 25.422-b05, mixed mode)
$ docker run --rm openzipkin/java:test -version
openjdk version "1.8.0_432"
OpenJDK Runtime Environment (IcedTea 3.33.0) (Alpine 8.432.06-r1)
OpenJDK 64-Bit Server VM (build 25.432-b06, mixed mode)
```

To release the image, push a tag matching the arg to `build-bin/build` (ex `8.422.05`).
To release the image, push a tag matching the arg to `build-bin/build` (ex `8.432.06`).
This triggers a [GitHub Actions](https://github.com/openzipkin/docker-java/actions) job to push the image.
