compose-spec VS Podman Desktop

Specification: https://compose-spec.io

https://github.com/compose-spec/compose-spec/blob/master/spe...

There are a number of incorrect statements in this post.

1) One should neither be using the "latest" nor just the "version" tag as the version can still vary depending on when it is pulled.

Instead, one should use a combination of version + hash, say alpine:3.18.2@sha256:82d1e9d7ed48a7523bdebc18cf6290bdb97b82302a8a9c27d4fe885949ea94d1 for reproducibility reasons. This provides for human readable versions as well as the specific hash.

2) Next, afaik, Compose has removed the need for version tags. All of the compose.yml files that I now use do not specify versions.

See https://github.com/compose-spec/compose-spec/blob/master/04-...

Docker Compose v2 specifications provide a useful Secrets feature which may also be used for standalone Compose Application Stacks and not just in Docker Swarm mode. With Docker Secrets the environment variables that contain credentials for other subsystems are mounted into the Telegraf Container as files. These secret files are read through the Docker Secret Store plugin and passed to the respective plugins in a relatively safe manner. By using the Docker Secret Store Plugin, one can also avoid credentials that were previously visible via environment variables, to be now hidden behind runtime secret files within the container. Standard Method with Environment Variables As an example, it is possible to pass the credentials to a plugin via the environment variable placeholder in a telegraf configuration file where the credentials for a plugin exist in a .env file (e.g. MQTT input Plugin)

also the docker-compose.yml file is very picky about what you have in it and where. Please read this so you know how to format it https://github.com/compose-spec/compose-spec/blob/master/spec.md

As part my quadlet helper tool, podlet, I'm adding functionality to convert compose files into k8s yaml to use with quadlet as an alternative to creating a bunch of separate quadlet files, which I've also added functionality for. So I would like to be able to transform the options on compose volumes into k8s yaml. For example, using the volume.podman.io/driver annotation to change the volume driver for a specific volume if possible.

If you find this helpful feature, please leave your feedback and suggestions here.

The compose spec will give what you need. https://github.com/compose-spec/compose-spec/blob/master/spec.md

Indeed, as per the compose-spec a lot of what was version specific is going away

Hello everyone, I just made a tool to visualize compose files, and all the parsing rules follow the [compose-spec](https://github.com/compose-spec/compose-spec/blob/master/spec.md). I hope this tool will help you :D

A new, search-driven command palette is now available to enable quick access to various commands available across 🦭 Podman Desktop. You can try this new tool out by hitting the F1 key. #4081 && #3979

Please share this experience and what went wrong with the postman team. It is the only way things can improve.

You don’t have to solve the problem. Just state your problem. If you need inspiration, here is an example: https://github.com/containers/podman-desktop/issues/868

I wanted to try a while ago so I downloaded Podman Desktop, but I couldn't get past the initial setup due to issues in the desktop app. I was able to reproduce this on two or three Macs, can't recall exactly.

It has been a long-standing issue but seems as though it is on its way to resolution: https://github.com/containers/podman-desktop/issues/1633.

I am waiting for a few months to make sure it is all sorted and will try again to see if it works then.

I'm not happy with Podman Desktop's Svelte GUI.

Antd or MUI (React) feel much more mature.

But they are working on it.

I don't know if that's really a core difference from podman. Assuming I track your meaning Podman has GUI management as well and it can be made to integrate with system and can produce Kubernetes manifests from the pods you define locally.

Optional extensions will follow their own lifecycle and update independently from Podman Desktop. As of this release you'll be able to see when there is an update available and install from within Podman Desktop #2655.

Podman Desktop 0.15 embeds Podman 4.5 in Windows and macOS installers #2115.

u/Chunkypewpewpew it's karpersky that has a false positive https://github.com/containers/podman-desktop/issues/700

Podman Desktop has a new release: you can check milestone v0.11.0 and Release Notes

> docker desktop is pretty dead now that it's got restrictive licensing etc...

It would probably be nice to hear more about why you think this is! I've certainly heard of some having to move away from Docker Desktop.

However, at the scale where you need a license (250 employees or 10 million $ in annual revenue) it's not quite as big of an issue, especially at their current pricing per seat: https://www.docker.com/pricing/

> stick to standard open source tools like Colima etc...

Sticking to open source is a great idea!

I think mentioning that Colima runs on macOS and Linux only at the moment is also a good idea: https://github.com/abiosoft/colima

A large market share of the Docker Desktop installs are Windows in particular (since it's "the one way" how most install Docker nowadays, as opposed to not really needing a GUI or the supporting tools on Linux).

In another comment I mentioned Podman Desktop as a mostly viable alternative: https://github.com/containers/podman-desktop

Then there's also Rancher Desktop as well: https://github.com/rancher-sandbox/rancher-desktop

Regardless, it's nice to see reputable orgs behind the open source projects as well, which gives a bit more credence to their chances of surviving for the years to come.
