Building a docker container using CI

[yash kumar]

Hi, 

I want to build my python project in a docker container using the Kraken CI. I found out that we can use Docker executor, but while using it, shows error 500. I tried testing the Earthly project from the kraken github, that also shows 500 error. 

My question is, Can I install docker on the normal non-docker executors? Though I tried but failed.

Yes, you can install Docker. All your cases are supported.

Could send me some logs of these failures?

Regards,

Michal
