Doesn't use socket from current docker context

[bzoks]

In Docker Desktop (for Linux), when trying to analyze local image, dive doesn't use current docker context endpoint (socket), but apparently always uses "default" endpoint (/var/run/docker.sock), which means it fails to access images built under Docker Desktop environment. Example: Docker Desktop turned off. Built an image. I'm able to analyze it:

$ dive 627547a71182
Image Source: docker://627547a71182
Fetching image... (this can take a while for large images)
Analyzing image...
Building cache...

When I start Docker Desktop (or switch docker context), this same image is still accessible by dive, even if it is not available for docker (under current context):

$ docker image inspect 627547a71182
[]
Error: No such image: 627547a71182

When listing images from current (Docker Desktop) context, listed-ones are not accessible to dive:

$ docker image ls
REPOSITORY                                                          TAG          IMAGE ID       CREATED         SIZE
something_phpfpm-pa                                                latest       36328f223adc   11 hours ago    114MB

$ dive 36328f223adc
Image Source: docker://36328f223adc
Fetching image... (this can take a while for large images)
Handler not available locally. Trying to pull '36328f223adc'...
Using default tag: latest
Error response from daemon: pull access denied for 36328f223adc, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

exit status 1

Output of docker context ls:

$ docker context ls

ecs-prod            ecs  

(asterix on desktop-linux line shows which context is current, so which will be used for all docker commands).

I tried also running dive using docker run and mounting correct endpoint (so the one from current context), but it still didn't worked...

bump: please make the Docker REST API endpoint configurable on CLI, so that dive can also be directly used with other engines, such as podman that support the Docker REST API; these tend to run on their own socket API paths in order to allow side-by-side co-existance.

Hi.

I have just faced with this problem. Use this environment variable to change default socket. DOCKER_HOST=unix:///home/kamil/.docker/desktop/docker.sock

Of course home catalog may be different :)

On macos, if you have Advanced/User settings ("Choose how to configure the installation of Docker's CLI tools"), you'll need to do this to make local builds work:

export DOCKER_HOST=unix:///Users/yourusername/.docker/run/docker.sock
