Error 404 when downloading the released binary

[dhiller]

There was one case when the krew-release-bot ran into a 404 error as he'd tried to download the released binary.

I suspect that this rather was a failure on the CDN of GitHub as the released binaries should already have been present. When I tried to download the file manually (by clicking the link in the browser window) it succeeded right away.

oh. let me see if some info in logs of the bot.

thanks for reporting it

i will close this for now as it does look like a CDN problem. If it happens again and more frequently, then we will explore the option of retrying etc.

[dhiller]

/reopen

Had this again twice now:

• https://github.com/kubevirt/kubectl-virt-plugin/runs/1859240444?check_suite_focus=true#step:4:8
• https://github.com/kubevirt/kubectl-virt-plugin/runs/1780812104?check_suite_focus=true#step:4:8

[dhiller]

This has prevented the release tonight and a version update that should have happened. Can you please take a look? Thanks!

[dhiller]

Fortunately I could restart the GitHub actions by hand, so no pressure :)

[rajatjindal]

Hi @dhiller

I will add some retry mechanism to handle this kind of transient failure.

[rajatjindal]

Hi @dhiller

sorry for the long wait, i've released v0.0.39 with this fix. now it will retry 4 times with backoff if the released tar file is not found.

in anycase if this happens again, please let me know

[dhiller]

Thanks for taking the time fixing this! :bow:
