Thank you @Sh1ftry ! Sorry for the delay, I haven't got any notifications from GitHub lately.

@weeco The build for this PR failed. I suppose it means that we don't have a release. Could you do a rebuild?

[weeco]

@amexboy Currently we are moving the build pipelines and docker registry from CloudHut to Redpanda Data due to the recent acquisition (see: https://cloudhut.dev/blog/2022-04-01-redpanda-acquires-cloudhut-kowl/), hence they do not yet work. I plan to fix the build pipeline by the end of this week though. Sorry!

[amexboy]

That would be awesome! Thank you so much

[weeco]

@amexboy Sorry it took longer than expected, but docker builds are now available under: https://hub.docker.com/r/vectorized/kminion/tags

[amexboy]

@weeco Thank you so much. I will give it a spin
