Need help in Dockerfile syntax error!

Software Docker

Hey everyone,

I’ve been working on integrating Docker into my project, but I’ve encountered a persistent error that’s been giving me quite a headache. Whenever I try to build my Docker image using a specific Dockerfile, I keep getting the following error:

Error Name: Dockerfile syntax error
Description: This error pops up when I run ‘docker build’ with my Dockerfile. Despite carefully checking the syntax and ensuring it follows Docker conventions, I can’t seem to figure out what’s causing this issue. I’ve tried various troubleshooting steps like rebuilding the Dockerfile from scratch, but the error persists.

Thanks in advance!

Hi @rohan02,

Welcome to the Stereolabs forums :wave:

Could you provide more information on the issue you are having? Can you share your Dockerfile as well as the docker build command you are using which results in these errors?

I do not see the error you are mentioning, the image seems to have been successfully built.

If you do not have any questions about the ZED SDK or Stereolabs products, I invite you to ask your questions on the Docker forums or on StackOverflow.
