JVM and Native images are available in the Docker Hub

https://hub.docker.com/repository/docker/treblereel/jscompressor/general https://hub.docker.com/repository/docker/treblereel/jscompressor-native/general

JVM based

  1. Clone the repository
  2. Run mvn clean package
  3. Run docker build -f src/main/docker/Dockerfile.jvm -t quarkus/jscompressor .
  4. Run docker run -d -v /home/${username}/${volumes}:/volume:Z -p 8080:8080 localhost/quarkus/jscompressor:latest

Native based

  1. Clone the repository
  2. Run mvn clean package -Pnative
  3. Run docker build -f src/main/docker/Dockerfile.native -t quarkus/jscompressor .
  4. Run docker run -d -v /home/${username}/${volumes}:/volume:Z -p 8080:8080 localhost/quarkus/jscompressor:latest

Note: You should be familiar with such topics like Docker root/rootless containers, selinux and such topics. For instance, if you get permission denied error, you should check the selinux context of the volume. That is why I prefer rootless Podman containers, that configure the context automatically.

Tips: If you are a mac user, check you build the native image for Linux. (docs docker buildx)

Configuration

The application can be configured using the following environment variables:

  • MAX_DOWNLOAD_FILE_SIZE - Sets the maximum file/script size that can be uploaded to the server. Default is 1048576 bytes (1MB).
  • MAX_DOWNLOAD_URLS_PER_REQUEST - Sets the maximum number of URLs that can be uploaded to the server. Default is 10.
  • MAX_CACHE_DIR_SIZE - Sets the maximum size of the cache directory. Default is 1073741824 bytes (1GB). Once limit is reached, the oldest files will be deleted.

All of the above can be set in the application.properties file or provided as environment variables to the docker container.
