  • There’s a container web UI called Portainer, but I’ve never used it. It may be what you’re looking for.

    I also use a container called Watchtower to automatically update my services. Granted there’s some risk there, but I wrote a script for backup snapshots in case I need to revert, and Docker makes that easy with image tags.

    There’s another container called Autoheal that will restart containers with failed healthchecks. (Not every container has a built in healthcheck, but they’re easy to add with a custom Dockerfile or a docker-compose.)


  • It’s really not! I migrated rapidly from orchestrating services with Vagrant and virtual machines to Docker just because of how much more efficient it is.

    Granted, it’s a different tool to learn and takes time, but I feel like the tradeoff was well worth it in my case.

    I also further orchestrate my containers using Ansible, but that’s not entirely necessary for everyone.

    You can tinker in the image in a variety of ways, but make sure to preserve your state outside the container in some way:

    1. Extend the image you want to use with a custom Dockerfile
    2. Execute an interactive shell session, for example docker exec -it containerName /bin/bash
    3. Replace or expose filesystem resources using host or volume mounts.

    Yes, you can set a variety of resources constraints, including but not limited to processor and memory utilization.

    There’s no reason to “freeze” a container, but if your state is in a host or volume mount, destroy the container, migrate your data, and resume it with a run command or docker-compose file. Different terminology and concept, but same result.

    It may be worth it if you want to free up overhead used by virtual machines on your host, store your state more centrally, and/or represent your infrastructure as a docker-compose file or set of docker-compose files.



  • I’m using a combination of:

    • The Boox Palma reader, though they have larger tablets if you prefer. I’m not sure about the others, but the Palma runs Android with the Play Store.
    • Kavita to host my ebooks online.
    • FolderSync with SFTP to sync all of my books ahead of time to my SD card.
    • Moon Reader to add my Kavita server’s OPDS feed as an online catalog if I need to grab something manually.
    • Calibre to manage and embed metadata.


  • It doesn’t quite say that, but I think the meaning is essentially the same: “Don’t choose a name after a project unique to that machine.” - RFC 1178

    For my homelab, I think that’s fine to do. I’m unlikely to have multiple Plex servers locally, for example, and if so, numerically naming them is fine - I provision with Ansible, and if I’m at the point where I’m having sequentially numbered hosts, they’ll be configured as cattle anyway. Also, having the names reflect the services a host provides makes it easier to match in my playbooks.

    I think it’s a better scheme than turning to mythology, fiction, or animal species, which oddly enough RFC 1178 does encourage you to do.
