Need to update GitHub actions, after that will be good to go.

You should add --retry-delay ( for example --retry-delay 30 ) to curl. Otherwise, curl will use an exponential backoff algorithm.

When curl is about to retry a transfer, it will first wait one second and then for all forthcoming retries it will double the waiting time until it reaches 10 minutes which then will be the delay between the rest of the retries. Using --retry-delay you can disable this exponential backoff algorithm and set your own delay between the attempts

Source: https://everything.curl.dev/usingcurl/downloads/retry#tweak-your-retries

This means:

request	delay in seconds
1	1
2	2
3	4
4	8
5	16

Using the exponential backoff algorithm results in an overall delay of only 31 seconds.

You missed my comment?: #5269 (comment)

You can keep it:

# List of sources to destination (final path):
COPY --from=build \
  /usr/local/bin/bun /usr/local/bin/bunx \
  /usr/local/bin

Comparision:

# Resolved with single COPY, symlink works:
$ docker save local-bun-build | gzip -c | wc -c | numfmt --to iec
40M

# The duplicate issue that previously existed:
$ docker save oven/bun | gzip -c | wc -c | numfmt --to iec
97M

# Resolved vs original image size:
$ docker images
