Dockerfile to run this maven cache?

[jamshid]

Found this project in a search, will give it a try, thanks! I'm having no end of problems using artifactory as a maven cache. Building maven projects in docker really needs a caching maven proxy since it's hard to share a ~/.m2/repository with docker builds.

I could try to make a Dockerfile to build and run this project. But sorry I'm not sure what the settings.xml should look like for this? Below is artifactory's, is this all that is needed?

I just got this working (mostly) for a Maven build using this docker image:

docker run -p 5956:5956 --name tiny-maven-proxy slamdev/tiny-maven-proxy

Then running my mvn build steps using:

mvn -gs /opt/build/mvn-mirror-settings.xml <command>

With a /opt/build/mvn-mirror-settings.xml of:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <mirrors>
        <mirror>
            <id>tiny-maven-mirror</id>
            <name>tiny-maven-mirror</name>
            <url>http://192.168.99.101:5956/</url>
            <mirrorOf>maven2,central</mirrorOf>
        </mirror>
    </mirrors>
</settings>

Two problems in my tests:

1. there is an issue with the maven build process hanging after a request is made through the proxy for an artifact the proxy can't find. I'm still tracking down why that's happening.
2. This is faster than downloading the artifacts directly, for sure, but it's still a lot slower than directly building from ~/.m2/repository/.

UPDATE The hanging seems to be related to this issue: #10 - I have no issues when I only use the single repository https://repo.maven.apache.org/maven2/
