Running on windows: "panic: exec: "docker": executable file not found in $PATH"

[christian-laakmann]

HI,

I am trying to run dive using the provided instructions for windows:

docker run --rm -it -v /var/run/docker.sock:/var/run/docker.sock wagoodman/dive:latest <some:image>

This is the output:

Analyzing Image

Is there a workaround for windows?

I had the same problem just tonight! I tried sharing the Windows docker binary, but that doesn't make much sense (as this image is some kind of Linux).

PS> docker run --rm -it `
>>     -v /var/run/docker.sock:/var/run/docker.sock `
>>     -v "$((Get-Command -Name docker).Source):/bin/docker" `
>>     wagoodman/dive alpine

So, I figured docker must be in the MobyLinuxVM that's running under-the-covers, right? Apparently the latest Docker for Windows can figure out when you want to pass a VM path vs. a Windows path (you previously had to use an extra forward slash to escape it or something).

PS> docker run --rm -it `
>>    -v /:/test `
>>    alpine find /test -name docker -type f
/test/user/local/bin/docker
...

OK, so it's in there, we can use it! This command worked on my machine!

PS> docker run --rm -it `
>>     -v /var/run/docker.sock:/var/run/docker.sock `
>>     -v /usr/local/bin/docker:/bin/docker `
>>     wagoodman/dive alpine

@AnthonyMastrean thanks for taking a look at this, I don't have a windows box readily available so this is a huge help.
