Comment on Got any security advice for setting up a locally hosted website/external service?
dgdft@lemmy.world 4 days agoYou shouldn’t suggest UFW at all then. There are other firewall options that can be used just fine with docker.
It does have real potential to cause serious issues, e.g. if OP were to put their server in DMZ mode on their router and later copy some docker setup instructions that don’t explicitly bind to localhost.

Please tell me more, which firewall would you recommend that plays nice with Docker?
No NAT? Hahaha that’s a big if, and why would you copy paste a docker compose without reading it?

Firewalld
Another user in this thread suggested DMZing, so combine your advice with theirs and boom. It’s not uncommon. Most people don’t knowingly choose to use a firewall that they don’t intend to work, like you would.
There’s more than one way to use docker. Spinning up an official mysql image using the official
docker runORdocker composecall suggested by the docs would start up a server wide open to the entire internet if DMZ’d.
