Hi everyone! So I installed docker the other day and I’m currently getting used to the terminal. I had a few questions about self-hosting web apps that would determine what apps I start using.

  1. If I hypothetically moved, would the change in IP address affect anything?
  2. Can other people on my internet access my webapps?
  3. Would a VPS solve any issues caused by question 1/2? Or is there a different type of software that would help?
  4. When I install an app and they both require the same localhost, is there a list of numbers that I can use as an alternative? For example, instead of 8080 could I use a hypothetical number like 1234?

Thank you very much. Sorry if these questions seem rather obvious, I’m just very new to self-hosting and I don’t want to lose any data in the future. 😅

    1 - Possibly yes, depends if you configured to auto detect like linking to Eth0 or an app accepts 0.0.0.0 as a key to auto detect local ip

    2 - Some routers allow you to isolate devices, some don’t. So you just have to check it out.

    3- yes

    4 - technically, you can do anything from 0 to 65535, but some are usually reserved, like 20 for file transfer, 22 for SSH, 25 for SMTP, etc.
