Checked in Docker Hub, seems like the tag exist

Might be an issue with Fly’s remote builders. To unblock yourself for now, see if building your app’s docker image locally (wherever the flyctl cmd is run from) works: fly deploy --local-only.

Switch to remote builders whenever they recover.

3

After installing docker on my machine, fly deploy --local-only works.

In fly.io Status doesn’t seem like they reported any incident :face_with_diagonal_mouth:

If you’re okay, can you share your Dockerfile? Fly’s remote builders cannot pull from private repositories, and that’s another thing to keep in mind. Here are some workarounds (other than --local-only), if that’s the case: Fly deploy permission denied connecting to Docker daemon - #2 by ignoramous

Welcome to the world of Fly.io, I guess :wink:

Will look into your workarounds. Thanks!

Here are my Dockerfile. I didn’t change anything since I ran fly launch

I guess it resolve itself after few days. Thanks for the help!
At least I know what to do if this happen again

Not sure if this is related or not
