Some notes now that I've finally finished this: - Docker Desktop is not required thanks to mCoding basically using it as a visual reference and sticking to CLI, you can just install the Docker Engine if you want - If you do install only Docker Engine, note that you will need to install Docker-Compose separately, and note that all commands will be "docker-compose" instead of "docker compose" - Although development is not the focus of the video, typing out everything will take longer but also gives you time to digest all the moving parts - Don't forget to import 'os' and from uuid import 'UUID' and 'uuid4' in the python code. In fact, always double check the imports as mCoding only mentions the vital packages Great video, I went from knowing of Docker as a concept to feeling confident enough to start incorporating it into my development work. I cannot express how nice it was to start using Compose after a succession of minor edits to files trying to fix errors. Thank you!

Excellent tutorial! I wish Docker could help me where I struggle with dependency and compatibility issues most, but I don't think it can. I am an embedded developer (so no support for Docker on our targets), but as such, you end up with various different tool chains and libraries on your computer, often causing compatibility issues or at least quite a headache until you got things configured to somehow cooperate. But with us working in a Windows environment (because our IT department doesn't know Linux🙄) and most of these tools being GUI based, I don't think that Docker could help containerizing things there. For us, it goes so far, that we started a project not too long ago using a 20 year old tool chain (which doesn't even support C99 or C++98 fully), because we can't install a newer version - that would break the old version which we still need to run to support older products. You just can't have both versions on one computer at the same time, it has even been confirmed by the tech support of the tool chain vendor.. (At least I found a way to use VS Code instead of their crappy editor and get things somewhat integrated, but it still sucks...) And of course we don't have the manpower to convert the legacy code to the new environment, which (of course) is not compatible in some finicky ways (let's just say that previous generations of programmers exploited erroneous behavior of this very compiler - so if a newer one does things right, have fun)... And of course being bound to Windows means that you can't just spin up separate VMs for everything either, as for each and every one of them you would have to get licensing straight.

I just thought that Docker would provide the isolation to begin with. I did the .venv and it seems to work fine. Then I nested containers without .venv which made it slimmer in terms of resources it’s using. But the same effect as far as I can tell. I imagine in production you’d want that generally speaking.

@VideoklipBG2 ай бұрын
One problem I can't seem to find a solid answer to that has made it difficult using Docker is how do you modify the host's firewall without restarting the daemon? Most firewals use iptables under the hood and the Docker daemon creates its iptables chains and many virutal networks as needed, say for a docker-compose app with some ports exposed to the host. After changing firewall rules (e.g. for exposing a port on the host publicly) by doing `iptables flush` or `iptables-restore ` all networking configuration for Docker is gone and the entire service needs to be restarted with all currently running containers in order to regenerate it and have the networking work again. This is not acceptable as I often need to modify the firewall for development and testing purposes and have long-running applications as well without interruption. Some advice?

Nice video! One thing though, why would you use a .venv inside along with docker containers? Thanks.
@mCodingАй бұрын
Thanks! In theory, you use a venv in a docker container for the same reason you use one on the host. Outside a venv, python is your system python, and critical programs required for your operating system to function might depend on the packages already installed. You installing new ones or upgrading them might therefore break your system (inside the container). In practice, I have not had an issue with this even once and I haven't seen anyone use a venv inside docker in production. But in theory, it could be a problem.

Quick question - at 35:55, why copy and install the wheels instead of installing "normally" in the builder and then just copying the python site-packages directory?
@mCoding2 ай бұрын
Hmm I think either one should work fine. In general if you had build dependencies they would be in your site packages too so you would want to start fresh and install wheels to avoid copying build deps. In this case we didnt have any so I don't see any reason copying the site packages wouldnt work too.

@mCoding2 ай бұрын
If you are using Docker Engine directly with local volumes, then you can find them as just a plain directory somewhere. With Docker Desktop it becomes slightly more obfuscated because the volumes live within the Docker Desktop VM for performance reasons. If you are using other volume types besides local, like an efs volume, then it becomes increasingly more inconvenient to work with them outside containers!
