container build hangs on downloading BuildKit image

[steinwaywhw]

Hi community,

I'm running container build . and it hangs on this step

[1/3] Fetching BuildKit image [a really really long time]

What can I do to debug more and understand what it is blocked on? I'm running this

container CLI version 0.2.0 (build: release, commit: 3b5c253)

Hi @steinwaywhw! Are you able to collect container logs by running this:

container system stop
container system start 
container system logs --follow
<repro issue>

Then providing that output? This output may include details about your images/containers/setup that you may want to censor, as a heads up.

Also, could you elaborate on how long the image fetching is taking? Like is it more than 5 minutes, etc?

Sorry I'm not used to checking GitHub notifications but here you go.

When I'm in this state, I also tried to stop it by

container system stop

It prints out these

Seems like the service is not running but I'm also not sure how to run it.

I install using brew install container, and I also tried brew services start container but it seems that the service is always in a stopped state using brew services
