Localstack deployment fails

[MarioSimou]

When I deploy my code in a locastack container, the cloudformation deployment fails and I am not sure why. Initially I thought is a bundler issue, so I tested it with webpack and esbuild, but unfortunately the issue persists in both of them. I have also tested the issue with different versions of localstack(v1.4, v2.2). In all cases the deployment failed.

Below, you will find the error message I get:

I have aslo created this repository.

Steps to reproduce:

• Install node dependencies (pnpm i).
• Run localstack container. I am using v2.2 (docker compose up -d localstack).
• Deploy lambda function in localstack (pnpm deploy:dev). You should get the error message that I shared above.

Hi @MarioSimou , thanks for reporting. Can you please enable DEBUG=1 in the LocalStack container environment, and then share the detailed debug logs here? This would be very helpful for us to reproduce and resolve this issue. Thanks for your help!

Okay, I found the issue. I am not sure if its written anywhere in the documentation, but the localstack container needs to have the docker volume (/var/run/docker.sock:/var/run/docker.sock) attached to it. If not, cloudformation fails with an error similar to the one I shared above.

Do you think I should add this issue in the readme?

Hi @MarioSimou,

great to hear that identified the problem! So we could close the ticket, or do you still have any issues?

We do have a documentation, respectively an example of the docker-compose.yml in our docs here.
It also states that the mount is required for lambda to work:

Mounting the Docker socket /var/run/docker.sock as a volume is required for the Lambda service. Check out the Lambda providers documentation for more information.

Would you still expect additional information in our docs?

Feel free to close it then. Thanks
