Docker: Why Am I Getting "Permission Denied" When Running My Container?

Docker: Error Creating Shim Task - Permission Denied

When attempting to build and run a Docker container, you might encounter the error "docker: Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "./deployment-service": permission denied: unknown." This error occurs due to insufficient permissions to execute the ./deployment-service executable within the container.

Solution:

To resolve this issue, add the following line to your Dockerfile before the CMD ["./deployment-service"]:

RUN chmod +x deployment-service

This command will grant execution permissions to the ./deployment-service executable, allowing the container to run successfully. Here's the updated portion of your Dockerfile:

...
# ... Code before this line ...

RUN chmod +x deployment-service

CMD ["./deployment-service"]

After adding this line, rebuild and re-run your Docker container. You should no longer encounter the permission denied error.
