It's been inspired by official Redmine image but optimized in size. Image has mysql and sqlite3 support built in. Also there is image with fast web server Unicorn for production usage.
If you need another database or web server or even some scm support feel free to inherit these images from Docker hub.
Test run:
docker run -d -p 3000:3000 inspiredgeek/redmine-alpine
More close to production run with unicorn:
docker run -d -p 8080:8080 -v redmine-files:/usr/src/redmine/files inspiredgeek/redmine-alpine:unicorn
