Running AWS SAM projects locally get error

Question

I am trying to run an AWS Lambda project locally on Ubuntu. When I run the project with AWS SAM Local it shows me this error: Error: Running AWS SAM projects locally requires Docker. Have you got it installed?

Answer 1

I had trouble installing it on Fedora.

When I followed the Docker postinstall instructions I managed to get past this issue.

https://docs.docker.com/install/linux/linux-postinstall/

I had to:

1. Delete the ~/.docker directory;
2. Create the "docker" group;
3. Add my user to the "docker" group;
4. Logout and back in again;
5. Restart the "docker" daemon.

I was then able to run the command:

sam local start-api
