No... You can not run docker container in lambda function... — Chetan

Sadly, you can't run docker in the lambda environment. However, even if you could the usefulness of it would be very limited as lambda can run for maximum 15 minutes.

If you want to run docker applications on AWS, there are two options which are usually used for this purpose:

The later is basically serverless equivalent of the first one, where you can just deploy your docker containers and don't worry about managing/scaling underlining infrastructure.
