flyctl VS s6-overlay

For frontend deployment, I used Netlify (for the generous free package) and the recommended fly.io for server + database (also cheap package).

Create an account on Fly.io.

You can learn more about fly.io and tigris, we will need to create an account on both platforms for this project regardless. Anyway with the theory out of the way let's get started in the next section as we create our accounts and start building the app.

Fly.io is a platform that helps you run your apps and databases closer to your users all around the world. It takes your app code, packages it up neatly, and puts it on virtual machines that can be quickly started or stopped. This makes your app faster for users and more reliable. Fly.io is easy to use, works well for small projects or personal apps. It's a great way to make sure your app runs smoothly for people no matter where they are.

In this post, we'll start from scratch, running FerretDB locally via Docker, trying out the connection with mongosh and the MongoDB Node.js client, and finally deploy FerretDB to Fly.io for a production ready set up.

2- fly.io

Fly is a cloud platform that focuses on global edge computing. Fly specializes in high-performance hosting and provides a global network of edge locations. Fly is known for its scalability and performance optimizations.

But videototextai.com is built using NextJS + Firebase auth + Firestore and a backend deployed at fly.io . Fly makes it really easy to deploy docker containers and that is IMO the fastest way to develop, you can setup a local setup

Alternatives explored: * northflank: While running the wrk test, requests were taking 3-7 seconds. Couldn't repeat Heroku's phenomenon of "400ms-800ms" during such a load test. * fly.io: Reliability: It’s Not Great * render.com: I remember the time when indiehackers.com was down because of an outage on Render, not sure if it's worth trusting.

For personal/portfolio projects fly.io and render.com both have free tiers that support the major backend frameworks and Postgres at the very least (although I think with Render at least the DB expires and has to be reloaded after a certain amount of time, have not personally tried it).

Learn S6-Overlay that allows to have one docker container for multiple processes... make immich docker compose not a two page 8 containers long? But just one clean container with healthcheck. Convince the devs to switch to it.

Custom base docker image with S6 overlay (for more details : just-containers/s6-overlay)

https://github.com/just-containers/s6-overlay can do what you need.

Used s6-overlay[1] to start a lot daemons in a docker-image for demo purposes - postgres, tomcat, mysql, php-fpm, apache (don't ask why ;) - s6 worked really well and was reliable and stable - I enjoyed it very much. It was also possible to reliable pass SIGTERM to the daemons in the image for clean shutdown and it was easily possible to configure logging to stdout with a prefix. Modelling dependencies (waiting on database before starting app etc.pp) is possible via shell-scripts. It's super flexible but out of the box it's more like a collection of powerful tools not a complete package - but that's good. It's in the tradition of djb daemontools and is very unix - as in doesn't talk a lot and you better know how each part works but - and that's really cool - it's modular and simple and once you get a grip on it you can easily reason about it. systemd takes a completely different approach and also solves a kind of differnt problem - this is like small pieces of lego that compose well instead of one big chunk of glib/dbus/glibc only c-code.

Every container has some entrypoint, whether it launches a single binary, runs a "process supervisor" like s6, or does some pre-setup before running a service, like a database.

If you *really* want to make your own containers with PUID/PGID support checkout "S6-overlay" and the linuxserver "baseimage". Somewhere in the startup they end up running:

FROM ubuntu:20.04 ARG S6_OVERLAY_VERSION=3.1.0.1 ARG DEBIAN_FRONTEND=noninteractive ENV TZ="America/New_York" RUN apt-get update && apt-get install -y xz-utils ADD https://github.com/just-containers/s6-overlay/releases/download/v${S6_OVERLAY_VERSION}/s6-overlay-noarch.tar.xz /tmp RUN tar -C / -Jxpf /tmp/s6-overlay-noarch.tar.xz ADD https://github.com/just-containers/s6-overlay/releases/download/v${S6_OVERLAY_VERSION}/s6-overlay-x86_64.tar.xz /tmp RUN tar -C / -Jxpf /tmp/s6-overlay-x86_64.tar.xz RUN apt-get autoclean && rm -rf /tmp/* ENTRYPOINT ["/init"]

Not sure about unbound or what have inside the pihole base image, you may try to run the service in foreground or use some tiny init service for that container (I just learnt that s6 may work for that, but you must be aware how it should be used)
