Description
We noticed a large number of resets happening while pushing the images and cache to repositories (3rd parties).
write tcp 172.17.0.2:41332->_Redacted_:443: write: connection reset by peer
We saw this exacerbated around May - June, 2023. And they caused the image pushes to fail as the resets became more than the number of retries.
Reported this to GitHub and they helped us with investigations and provided a fix, which was to set the network to Host.

image=moby/buildkit:v0.11.6
network=host
Posting this here, as this could help others coming across it.
Tried various versions of Buildkit and as you could see in the config, this problem is there with 0.11.6. At the time of raising this issue, this is/was the latest version.
It was spotted by GitHub that the 'bridge' mode was the culprit.
May be someone from Buildkit can look into this, as the problem could be something not working cordially with GitHub's runners or the network provisions around them. It might be an issue with TTL being set too low.
This also seems similar to an earlier issue here:
Issue-2713
but it might not be the same problem.
