Permission denied on docker run

[ffuf-kumar]

Hi,

i have scoured through internet but couldn't find an answer which is acceptable to me.

I am new to packeto and trying to run the build via packeto image
docker run -v /var/run/docker.sock:/var/run/docker.sock -v $PWD:/workspace -w /workspace buildpacksio/pack build my-image --builder builder-image
I got this command from https://buildpacks.io/docs/tools/pack/#install

But when i run it i get an error

ERROR: failed to build: failed to fetch builder image 'index.docker.io/library/builder-image:latest': Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post "http://%2Fvar%2Frun%2Fdocker.sock/v1.38/images/create?fromImage=builder-image&tag=latest": dial unix /var/run/docker.sock: connect: permission denied

I assumed this is somehow related to docker socket issue, but if I run
docker run \ -v /var/run/docker.sock:/var/run/docker.sock \ -v $PWD:/workspace -w /workspace \ buildpacksio/pack builder suggest

I get a valid( i think) response

Suggested builders:
Google: 'gcr.io/buildpacks/builder:v1' Ubuntu 18 base image with buildpacks for .NET, Go, Java, Node.js, and Python
Heroku: 'heroku/buildpacks:20' Base builder for Heroku-20 stack, based on ubuntu:20.04 base image
Paketo Buildpacks: 'paketobuildpacks/builder:base' Ubuntu bionic base image with buildpacks for Java, .NET Core, NodeJS, Go, Python, Ruby, Apache HTTPD, NGINX and Procfile
Paketo Buildpacks: 'paketobuildpacks/builder:full' Ubuntu bionic base image with buildpacks for Java, .NET Core, NodeJS, Go, Python, PHP, Ruby, Apache HTTPD, NGINX and Procfile
Paketo Buildpacks: 'paketobuildpacks/builder:tiny' Tiny base image (bionic build image, distroless-like run image) with buildpacks for Java, Java Native Image and Go

Tip: Learn more about a specific builder with:
pack builder inspect

This leads me to believe something is wrong in the first command.
Am I missing something here?

My machine is
Ubuntu 22.04.01
64 Bit
Docker version 20.10.17, build 100c701

This strikes me as a permissions issue with the Docker socket inside the container. I'm not super familiar with using this pack image to build apps. I usually just run the pack CLI directly on my machine. Its worth asking about this over in the Discussions forum for the Buildpacks project, or the pack repo directly.
