google colaboratory - Docker is not running on Colab

Question

I have tried to install Docker on google Colab through the following ways:

(1)https://phoenixnap.com/kb/how-to-install-docker-on-ubuntu-18-04

(2)https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-18-04

(3)https://colab.research.google.com/drive/10OinT5ZNGtdLLQ9K399jlKgNgidxUbGP

I started the docker service and saw the status, but it showed 'Docker is not running'. Maybe the docker can not work on the Colab.

I feel confused and want to know the reason.

Thanks

Answer 1

I had the same issue as you and apparently Docker is not supported in Google Colab according to the answers on this issue from its Github repository: https://github.com/googlecolab/colabtools/issues/299#issuecomment-615308778.
