- building the Dockerfile
docker build -t clj-graal ., compiles the project in testgraal to a binary. - to get compiled binary either use docker cp or mount a volume where the
binary is made
/home/clj/app/target/testgraal-0.1.0-SNAPSHOT-standalone
- blueprint for project laid down by https://www.astrecipes.net/blog/2018/07/20/cmd-line-apps-with-clojure-and-graalvm/ =======
A Clojure library designed to ... well, that part is up to you.
- build `` ./build.sh
- to use
./run.sh --help
- this scripts uses entyrpoint/command tricks to essentially turn the compiled
clj app into an "executable" docker container. If this is not what you want I
recommend starting the container, and using "docker cp" to extract the executable
or using the -v parameter to get the binary out of the running container.
## Compare
To test the difference between the two...
docker run -it --entrypoint /bin/bash testgraal
time java -jar ./target/testgraal --help
on my hardware: `target/testgraal --help 0.00s user 0.00s system 96% cpu 0.004 total`
versus
lein uberjar
time java -jar ./target/testgraal-0.1.0-SNAPSHOT-standalone.jar --help
on my hardware: `java -jar testgraal-0.1.0-SNAPSHOT-standalone.jar --help 3.68s user 0.19s system 216% cpu 1.787 total`
