Honestly, you already have the image locally if you’ve pulled it.

I guess not everyone treats their PC as an ephemeral storage, huh? I don’t trust anything that’s available only locally to survive.

1. For all the mentioned cases, if your firewall blocks incoming packets by default, no one can access it, no matter what is the source of the port being open.

2. You don’t configure it on the docker level, at least if you care about outside connections. If you mean from your local computer to a docker container, by default you cannot connect, unless you expose the port to the system. If you mean from other docker containers, just create your own separate network to run the container in and even docker containers cannot access the ports.

3. I usually use netstat -tulpn, it lists all ports, not only docker, but docker is included. docker ps should also show all exposed ports and their mappings.

In general, all docker containers run on some internal docker network. Either the default or a custom one. The network’s ports don’t interfere with your own, that’s why you can have 20 nginx servers running in a docker container on the same port. When you bind a port in docker, you basically create a bridge from the docker network to your PC’s local network. So now anything that can connect to your PC can also connect to the service. And if you allow connection to the port from outside the network, it will work as well. Note that port forwarding on your router must be set up.

So in conclusion, to actually make a service running in docker visible to the public internet, you need to do quite a few steps!

• bind a port to your local host
• have your local firewall allow connection to the port
• have your router set up to forward connections on the port to your machine

On Linux, local firewall is usually disabled by default, but the other two steps require you to actively change the default config. And you mention that all incoming traffic is dropped using UFW, so all three parts should be covered.

I once tried it for work, it was nice, just lying down in a comfortable position and simply moving the screen wherever I wanted it.

Buy a phone controller (like Razer Kishi or Razer Junglecat) and use some streaming technology to play your PC games on phone. My favourite is Sunshine/Moonlight combo, but Steam Link might work as well for you.

I’m using Proton mail, I like their focus on privacy and e2e (only with other Proton users, though).

On the 1st page I found exactly one game that I’d maybe want to play, but not like I couldn’t live without it. None on page 2 and one game again on page 3. Every single game I wanted to play on the Deck works (true, some of them needed some tinkering).

Remember, I said the solution is simple for me. Generally the games that don’t work are not really my cup of tea, like online games and generally stuff that’s more cash-grab than a game. There are few games that would make me consider getting Windows to play, but luckily all of those work well. I still wouldn’t install Windows on the Deck, though, I’d probably stream it from some PC.

Well, at least for me the solution is simple: don’t buy those games.

True, still a little salty I had to cancel the subscription, I genuinely liked it. But I’m not installing Windows.

We use .lh, short for localhost. For local network services I use service discovery and .local. And for internal stuff we just use a subdomain of our domain.

I personally only turn it off when someone’s visiting over night and the noise disturbs them, otherwise I just leave it on nonstop. Mainly because it would annoy me to try to open whatever and find out I have to turn on the server first. I don’t have a UPS and never even thought about getting one (for the server, I’m thinking of getting one for my 3D printer).

I have only positive experience with them. The only downside is it gets hot like hell, but other than that it works spectacularly.

Most games I bought are from GOG and I play them easily on my Steam Deck using Heroic Games Launcher.

Step-by-step:

1. Switch to desktop mode
2. Open Heroic Games Launcher
3. Install game from GOG
   1. Log in to GOG if you’re not already
4. Add the game to Steam launcher using Heroic
5. Switch back to gaming mode
6. Play

I use Proton Mail for my primary domain and then addy.io for redirects to it. It costs $10 a year or something like that and it’s all I actually need.

Replying to emails is as easy as just hitting reply, the only thing that’s slightly harder is sending entirely new email (as in not replying) but even that can either be remembered, or the special email address copied from the addy.io app.
