Unable to connect to docker.sock file while running dive

[hariprasadpo28]

I have been trying to run dive on some of my images, after running dive ubuntu:latest I am seeing this error:

Image Source: docker://ubuntu:latest Fetching image... (this can take a while for large images) Handler not available locally. Trying to pull 'ubuntu:latest'... latest: Pulling from library/ubuntu Digest: sha256:dfd64a3b4296d8c9b62aa3309984f8620b98d87e47492599ee20739e8eb54fbf Status: Image is up to date for ubuntu:latest docker.io/library/ubuntu:latest cannot fetch image Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

But I am able to use docker without any problems, docker is also running.
OS: MacOS 13.4
Docker engine: v23.0.5

A better solution is described by @Tantalor93 below

Original proposed solution
I had the same problem, but this is not an issue related to dive, this is more related to Docker and how docker.sock seems to be managed on Mac now.

A Docker upgrade on Mac moved the docker.sock from /var/run/ to ~/.docker/run/

An easy fix is:

ln -s ~/.docker/run/docker.sock /var/run/docker.sock

If sudo is required:

sudo ln -s ~/.docker/run/docker.sock /var/run/docker.sock

Note sure how long this fix can work, but for now, it is doing the job!

If you are using Docker Desktop on Mac, you can enable the option for creating the default Docker socket

This looks like a change in Docker Desktop 4.18 to allow installation on macOS without needing admin privileges: https://www.docker.com/blog/docker-desktop-4-18/ . It still asks for admin privileges, but if you don't grant them then tools like dive won't work until you enable this new setting.

This could be worth adding as a note to the installation steps. I ran into this issue too!

I haven't used my personal computer in quite a long time for programming. My Docker client updated itself to Docker Desktop - and at no point during the upgrade process did it prompt me for a password (and luckily I kind of stumbled onto this fix myself) 😅

I get a similar error since I switched from Docker Desktop to colima at my MacBook (Ventura 13.3.1). Dive (0.11.0) can not load a local image. Docker version is 24.0.4.

$>dive a6cfd372bba2

The post of TG-KK in #397 (comment) helped me.

For docker rootless: sudo ln -s /run/user/$(id -u)/docker.sock /var/run/docker.sock

[cjconnor24]

Awesome @Tantalor93 - this was sooo annoying thank you :)

Following instructions to setup rootless docker on ubuntu 24.04 I end up with a $DOCKER_HOST of unix:///run/user/1000/docker.sock and I still get "cannot find docker client executable".

[williamdes]

And did you run my command above?

[delanym]

@williamdes I already have a /var/run/docker.sock. I renamed it temporarily and tried your command. Dive still complains

$ dive redmine:5.1.3-alpine
Image Source: docker://redmine:5.1.3-alpine
Fetching image... (this can take a while for large images)
Handler not available locally. Trying to pull 'redmine:5.1.3-alpine'...

[williamdes]

cannot find docker client executable

Seems explicit, does docker --version work ?

[delanym]

I setup it up last week. Everything working. Docker version 27.1.2, build d01f264
Rather than fiddling with my system it would be more convenient to configure the socket dive should connect to
