This Docker Compose visual builder is the tool I wish I had as a beginner “If you’ve ever attempted to run too many containers on the same machine, you may have encountered failed deployments because multiple services tried accessing the same port. Fortunately, DCM sidesteps that issue by checking for port conflicts in your multi-container Compose files. Going back to our network stack example, Nginx and Pi-hole both use ports 80 and 443 on the host. If you try to deploy these services with the same Compose files, DCM detects the port conflicts and assigns different numbers to the second container.” With over 40 to 50 containers running on one of my servers I constantly run into that ports clashing issue (when ports are exposed to the host machine). This tool does look quite interesting as well as how it handles volume mappings. It also makes me realise how Portainer really needs to take a few steps forward with regard to better stack editing. I'm going to be looking a bit deeper into this app. It looks like it will work in tandem with Portainer too. Basically DCM will help you create a clean and functional docker-compose file to paste into Portainer.

Meet Roomy: An Open-Source Discord Alternative for the Decentralised Web “Roomy is an open-source Discord alternative built on the AT Protocol (ATProto), the same protocol that powers Bluesky, with ActivityPub (the protocol behind Mastodon, Pixelfed, Pleroma, and others) planned for the near future. Currently in alpha, it sits somewhere between Matrix and Discord in terms of its practical position in the broader chat ecosystem.” It is built on open protocols (no lock-in) and right now you can sign into the web interface using an existing Bluesky login, to be followed soon by any ActivityPub based ID (Mastodon, Pixelfed, Pleroma, etc). Interestingly, it will be bridging many diverse and decentralised networks. From what I understand of it, posts that each person makes to this service, physically go to their own registered servers (decentralised) with Roomy providing the merged view. It seems there are quite a few features still to be implemented such as Fediverse login, moderation regarding removing of users from a room, encryption, self-hosting of Roomy, desktop/mobile apps, and more. Right now Bluesky users can use their login to test it out. See https://itsfoss.com/roomy-discord-alternative and Roomy at https://a.roomy.space #technology #opensource #socialnetworks #decentralised
