Failing to deploy nginx docker

Questions / Help Build debugging
1

Hello, I’m quite new to fly.io and still wondering the best ways to deploy my apps. I’m trying to deploy my “production” build of a React app, using nginx + docker. I was successful deploying my backend application just describing the Dockerfile and running ‘fly deploy’, but for some reason it doesn’t work for nginx application.

Here’s logging of the fly deploy:

Just a quick note that building and running the docker locally works fine

3

In that case, you may try building the runc / docker image locally, instead:

flyctl deploy <args> --local-only

If not, and if it is okay, can you share your dockerfile?

4

With --local-only everything went well and it’s now deployed.

Dockerfile is pretty simple:

FROM nginx:1.22

COPY dist /usr/share/nginx/html

Is the COPY command causing issues when running deploy without --local-only?

5

From the logs, it seems the error in remote-builder (operated by Fly) happens when fetching the base nginx:1.22 image (and not when exec’ing COPY):

"[internal] load metadata for docker.io/library/nginx:1.22:"

"DEBUG result image:<nil> error:error building: failed to solve with frontend dockerfile.v0: failed to create LLB definition: unexpected status code [manifests 1.22]: 500 Internal Server Error"

Up to Fly engineers to figure out why nginx:1.22 wouldn’t build. A short googling after, this stackoverflow answer seems to suggest that Docker BuildKit is at fault.

In the meanwhile, you may want to try whether nginx:1.22-alpine or nginx:1.23-alpine or nginx:latest works with the Fly’s (remote) builders.
