To me, orchestration is not really the core problem. The bigger challenge is handling agent coherency over long periods of time, (drift) so my solution is a living forum-like system where agents shout to one another, document work in items, and follow doctrine handed down by the developer and work against a known specification that's checkable. I have used this workflow in several large projects that MUST be correct, and it works for me. Currently cleaning it up for other users.

Yup, I literally just hate their web UI. Once I found the Atlassian-blessed jira "cli" [0] (after searching for a long time for a tui, which is actually what the "cli" is primarily) I have actually be fine with using Jira again. As an added bonus, being a cli has made it easy to interface with using my AI tooling.
And I think most people who hate Jira actually just hate the process their company has imposed inside of Jira.
The vanilla out of the box product is actually quite close to old Trello, in simplicity. But there are so many ways to fuck it up and overcomplicate it, and so many companies proceed to fuck it up and overcomplicate it.

It's all about what story you can tell.
Cursor is easily the worst experience I've had with an AI harness, yet it was acquired for billions of dollars in spite of being a middleman tied to a ripoff of VS Code. None of the colleagues of mine who were touting it last year are still using it. But if you can make yourself look like the next big thing, you'll get money thrown at you. Just look at Omarchy.
A good experience necessarily takes time and careful thought. Nobody these days can do that while also remaining relevant, or even surviving.

Now Angular v1, man… if I ever see another digest loop error in my life, I will scream
ravenstine 43 minutes ago [-]
So glad I never had to deal with Angular, especially v1. I tried learning it and it just seemed like it would actually make applications more incomprehensible than before. React originally addressed the actual problem that most frameworks mistook for not being that important. I still don't particularly like React, but it makes sense why it became popular.

Go doesn't have a good mod/plugin story for harness devs to provide to their users
I say this as a gopher who also has a custom harness written in Go, it's a real challenge compared to the TS setups, but TS plugins are also a security concern
gandreani 3 hours ago [-]
I agree! Comes with the territory of a compiled language I suppose?
I haven't given this much thought (I also just started with golang last year) but I'm assuming the only real path here is to provide extension SDKs in Lua or other languages whose interpreters have been implemented in go.
I think that's what grafana's k6 [1] does with a JS interpreter
I was thinking I recalled something like that, but the nice thing about the TS ecosystem is that you can write the same language, importing and using the harness sdk types.
Go has the plugin package, but I haven't actually seen anyone use it (outside of toys and blog posts)
fails at step two, precompiled binary is already built, you can't change the code
why not just use an SDK where you are using a plugin?

Docker Agent is a harness. There is a sandbox mode that can be used to run it in docker sandbox (a VM, not a container). If you don't use sandbox mode then I assume it is running in a container.
If you don't want to use their harness then you wouldn't use docker agent and instead use their `sbx` cli to run the harness of your choice (claude, codex, pi, etc).
I think it will be great if Docker can get people used to using secure VMs. I am developing a similar project (still a work in progress): https://github.com/gregwebs/agent-vm
genghisjahn 3 hours ago [-]
I've found sbx to be very helpful. really like the sentinel value wrapper they have going so you can add secrets but the model can't see them. Outbound calls get looked up by sentinel value and the real one goes out to whatever API you're auth'ing too. There's other features but just having claude run in a sandbox and easily see what it does and doesn't have access to has been great.

Last year (2025), I lost count of how many times I tried using an LLM to set up Docker. It was still the era of prompting, then copy-pasting the response and seeing if it worked... and it almost never did. It’s great to see this new Docker agent. For me, it would be even more appealing to see an agent and a model specialized in Docker working together, capable of proposing advanced configurations and getting them working on the first try.

Modern models should be better with mainstream technologies like docker engine or docker compose, but still to try to help them we started to work on distributing skills ( https://github.com/docker/skills ) in addition of our specialized agent (gordon) integrated in various products.

Sessions just broke all the time for me. The one time I dug into it, it ended up being a known issue where if codex returned over 10k characters for a turn it breaks the session. Because docker agent does not use protocols like ACP, instead trying to parse Codex's internal state in a brittle manner.
I tried not to do anything too crazy, but even use using an API key in the docker agent natively was getting me sessions that would hang and couldn't be recovered.
Combination with Codex is indeed not the most common use case around us. I'll see what can be improved. Sorry that it broke your workflow!

How is not using it with the most popular coding agent not a common use case?

Not the most common use case around them: likely meaning that the Codex harness isn’t used that often internally at Docker, is what I would surmise, at least that is how I read it.
I work at another big tech company, and up until recently that would’ve been true for us as well (but it’s changed now, we partnered with OpenAI)

Docker Agent could be beneficial for research studies. For example, while writing a ML paper about agents I need to rerun experiments so that:
- others can repeat my results
- validate that variability from LLMs is not causing overconfidence in the results
But currently uv is good enough to create isolated, repeatable environments. And it isn't limited to Linux like standard Docker. So when I want to test small samples on my local PC's GPU (Windows or mac) before running on beefier hardware, I can do that easily.

There was a brief point in time at the beginning of the internet where if you saw an image online you could be kind of confident that it hadn't been manipulated significantly... But somewhere around the mid to late 2000s it became prudent to just assume any image you've seen online got at least a blemish filter pass through something like Photoshop.
Same thing now with written text. Sometimes you'll be a little bit more or less sure than an llm produced the output but never able to say 100% confidently.

You don't really have to use the docker agent sub-command. docker-agent is a standalone binary. When it was created, though, 1.5 year ago, the idea was that it would be the docker compose for agents (original name was cagent, compose for agents).
But it evolved differently and although it runs very well in docker containers and docker sandboxes, it also runs very well anywhere else.

Nowadays there are only two justifiable public languages you should be using for anything

Rust itself is dubious due to abysmal compile times and the fact that the only guarantees it gives you are of security (aka a skill issue). Modern LLMs write C++ that is as safe if not safer than Rust. Any other language choice is objectively wrong.
