They now have a chance to win the global competition, the prize being free ticket to DockerCon Europe, but only if they can get enough votes on the voting page: [https://docker.com/community/globalhackday](https://docker.com/community/globalhackday) Each city that hosted a Docker HackDay event also had the opportunity to choose a team for the ‘local winner’ prize. Local winners get higher visibility on the global voting page, giving that team a much higher chance of winning the global prize. Amsterdam’s winning project was [unblocker](https://github.com/bastichelaar/dockerhackday) created by Remmelt Pit, Bas Tichelaar and Simon van der Veldt: *“**The idea is that if you push a new image to a Docker registry, all the running containers with an old version of that image are automatically replaced by the new version.”* > “*Had a wonderful and inspiring Docker hack day. We created unblocker.py, a script that automatically upgrades Docker images on a server. It was great to be able to host the hack day.*” - Remmelt Pit, [Info.nl](http://info.nl/) Find links to more information about unblocker, and runner up team, binocular, at the end. The event was a great success, the community members enjoyed a great moment hacking together as evidenced the group pictures posted by Mark Coleman - organizer of the Amsterdam Hack Day - on his Twitter account [https://twitter.com/mrmrcoleman](https://twitter.com/mrmrcoleman) along with the numerous ‘favorites’ and ‘retweets’! --- *Links* Amsterdam Docker Meetup: [http://www.meetup.com/Docker-Amsterdam/](http://www.meetup.com/Docker-Amsterdam/) unblocker github: [https://github.com/bastichelaar/dockerhackday](https://github.com/bastichelaar/dockerhackday) unblocker demo video: [https://asciinema.org/a/13551](https://asciinema.org/a/13551) binocular github: [https://github.com/dockpit/binocular](https://github.com/dockpit/binocular) binocular demo video: [https://www.youtube.com/watch?v=HBotw-L04xY](https://www.youtube.com/watch?v=HBotw-L04xY) [### Slides from Berlin ](https://blog.container-solutions.com/slides-berlin) [![prev-arrow](https://cdn2.hubspot.net/hubfs/3842749/Wow%202019/Images/left-arrow.png) Previous article](https://blog.container-solutions.com/slides-berlin) [ Next article ![next-arrow](https://cdn2.hubspot.net/hubfs/3842749/Wow%202019/Images/right-arrow.png) ](https://blog.container-solutions.com/tour-docker-nl-unix-user-group) [ ### A Tour of Docker at NL Unix User Group ](https://blog.container-solutions.com/tour-docker-nl-unix-user-group) Comments Leave your Comment ![cs-logo-white](https://blog.container-solutions.com/hs-fs/hubfs/cs-logo-white.png?width=150&height=61&name=cs-logo-white.png "cs-logo-white") #### **Talk to sales** [info@container-solutions.com](mailto:info@container-Solutions.com) #### Stay In Touch - [**](https://www.linkedin.com/company/container-solutions/) - [**](https://twitter.com/containersoluti) © 2024 Container Solutions
