Devcontainer setup modal

[KyleBarton]

Adds the ability to create a dev container definition from scratch. Additionally, separates devcontainer logic out into its own crate, since it was getting sufficiently complex to separate from the recent_projects crate.

A screen recording of the modal experience:

Release Notes:

• Added modal to initialize a dev container definition in the project with projects: initialize dev container
• Added podman support for dev container actions with the use_podman setting
• Improved devcontainer error handling

This is great! Is there any documentation on how/where to use the new use_podman setting?

[conbruno]

where do i set use_podman? i get property not allowed in .zed/settings.json

{
"use_podman": true,
}

I am on Windows.

@conbruno the setting should exist at the root level. What version of Zed are you using? What you've written looks to be a valid settings object to me.

[astrosticks]

@KyleBarton I am on Fedora and Zed 0.225.10, and I can confirm that use_podman gives the error "Property use_podman is not allowed."

[conbruno]

@KyleBarton first of all thanks for your swift reply and sorry for my delayed response.

I can not tell you the version i was on then, but I am now on:
Zed 0.226.5
07dae3b

0.226.5+stable.197.07dae3b7020b0ad79ed91e18c750a16952432866

and I no longer get an error in .devcontainer/devcontainer.json when using the use_podman option.

However, I still get an error when trying to start the devcontainer:

... the weird thing is that nothing shows up in the logs. my last entry in the logs is from 2026-03-05.

I have the docker compatibility settings in podman enabled. Again I am on Windows.
