What I expect

• Successfully build the docker image.

Encore Version

encore version v1.39.5

Suspected Root Cause

The code that thrown the error:

https://github.com/encoredev/encore/blob/f8b785d73b213e01f25bbef44bccc5928b26d7e5/cli/daemon/export/export.go#L133-L147

Which from:

go-containerregistry/pkg/v1/daemon/write.go

Lines 66 to 70 in b8e87ed

	// write the image in docker save format first, then load it
	resp, err := o.client.ImageLoad(o.ctx, pr, false)
	if err != nil {
	return "", fmt.Errorf("error loading image: %w", err)
	}

Suspected related issues:

• daemon.Write implementation is pretty naive #205
• pkg/v1/daemon should avoid compression #552
• getting image ID (sha) takes longer than docker cli #627

Related issues:

• [ERROR]: encore eject docker <DOCKER_IMAGE_TAG> encoredev/encore#1316

Command

encore eject docker encore-nextjs

Tried Potential Solution

1. After identifying the selected docker context as desktop-Linux and its mismatch with the error given by encore, I switched it to default, and the error was still the same.
2. After that, I thought it was similar to could not start process: exec: "node": executable file not found in $PATH encoredev/encore#1309, so I restarted my Ubuntu machine, but the error was still there.

Let me know if there is any other info you need.

[Rakhmanov]

This is not a bug, your default context is not working.
When you switch with docker context to the one that does not give you error it does not applying to everything on your machine, only docker cli.

1. modify your default context to match the one that does not cause error when running docker version.
2. Alternatively you can provide DOCKER_HOST='unix:///home/imbios/.docker/desktop/docker.sock' environmental var to specify path where docker deamon is listening.

Otherwise you are asking a feature to have ability to specify docker context in go-containerregistry and in the encore.

@Rakhmanov If I may ask, how do I modify the default context (your first advice)?

UPDATE 1:

I tried, but still can't
