  • I guessed it was a “once bitten twice shy” kind of thing. This is all a hobby to me so the cost-benefit, I think, is vastly different, nothing on my setup is critical. Keeping all those records and up to date on what version everything is on, and when updates are available and what those updates do and… sound like a whole lot of effort when currently my efforts can be better spent in other areas.

    In my arrogance I just installed Watchtower, and accepted it can all come crashing down. When that happens I’ll probably realise it’s not so much effort after all.

    That said I’m currently learning, so if something is going to be breaking my stuff, it’s probably going to be me and not an update. Not to discredit your comment, it was informative and useful.

    When I asked this question

    So there are many reasons, and this is something I nowadays almost always do. But keep in mind that some of us have used Docker for our applications at work for over half a decade now. Some of these points might be relevant to you, others might seem or be unimportant.

    • The first and most important thing you gain is a declarative way to describe the environment (OS, dependencies, environment variables, configuration).
    • Then there is the packaging format. Containers are a way to package an application with its dependencies, and distribute it easily through the docker hub (or other registries). Redeploying is a matter of running a script and specifying the image and the tag (never use latest) of the image. You will never ask yourself again “What did I need to do to install this again? Run some random install.sh script off a github URL?”.
    • Networking with docker is a bit hit and miss, but the big thing about it is that you can have whatever software running on any port inside the container, and expose it on another port on the host. Eg two apps run on port :8080 natively, and one of them will fail to start due to the port being taken. You can keep them running on their preferred ports, but expose one on 18080 and another on 19080 instead.
    • You keep your host simple and empty of installed software and packages. Less of a problem with apps that come packaged as native executables, but there are languages out there which will require you to install a runtime to be able to start the app. Think .NET, Java but there is also Python out there which requires you to install it on the host and have the versions be compatible (there are virtual environments for that but im going into too much detail already).

    I am also new to self hosting, check my bio and post history for a giggle at how new I am, but I have taken advantage of all these points. I do use “latest” though, looking forward to seeing how that burns me later on.

    But to add one more:- my system is robust, in that I can really break my containers (and I do), and to recover is a couple clicks in Portainer. Then I can try again, no harm done.






  • Strict if the artist is alive. Much less so if they’re dead. Much, much less so if they’re dead, and so is everyone attached to them.

    I try not to separate the art from its context, I feel I get a more shallow experience by doing so. But, how much context, how I seek it out, etc are all up in the air. So when talking about a piece I’ll mention something of the context, the writer being living garbage is easy context to contrast/support against their work.

    Ender’s game being written by a bigot is interesting because of the contrast. H.P Lovecraft being a bigot is interesting because it is so obvious in the work.



  • You have cleared up a lot of misconceptions for me, I have not been port forwarding, I have not learned how yet. I think I’m good. I don’t mind breaking functional stuff, and have a lot already, but I really don’t want to explain to my fiancée that the reason someone is in her bank is because I wanted to watch Samurai Jack.

    I have been keeping it as insular as possible for this reason, and the next thing I intent to learn is to make it more insular by putting the pi on a subnet of its own. Actually, thank you for writing that up. I have been actively resisting using people for IT support, as I know it takes time. I have been trying to find everything I can, there isn’t much or what there is assumes knowledge I don’t have.

    There’s a comment with a list of stuff to do that I’ve saved. So I’ll probably start knocking that out one by one.




  • Both pi’s have static IPs.

    I asked the *arrs to talk to each other, and when they didn’t work (and only when they didnt work) I "ufw allow"ed the relevant port.

    I just want to patch up my firewall layer as best I can, and then start building security layers on top/below it as I learn how.

    So I told Sonarr that qBit it at 192.168…:port. The test failed, “ufw allow port”, then the test passed. Could I instead have told Sonarr qBit is at 172.18…:port(dockers network address) and then close up the firewall. Or can I set them all to “ufw limit”. Or set the firewall to only allow local local traffic… You get the idea, I know enough to be dangerous but not enough to ask the right questions.



  • ISP modem. I have a pi3 running pihole-dhcp-unbound, ufw and log2ram.

    My system is a pi4 running *arrs, qBit, fail2ban, portainer in docker and ufw for now. Use case is: via mobile phone access *arrs, let them do their things and manually play files via hdmi or move files via thumbdrive. I was thinking giving up the phone access to put them on their own network, but subnets are beyond my ken for now.

    Hoping to increment my security, and then the system as my skills develop.

    Edit, qBit and prowlarr are behind gluetun set up for mullvard. I’m in the UK so had to put the indexer behind a VPN. UFW
