Start a new container with the --security-opt seccomp=unconfined flag so that no seccomp profile is applied to it. From the terminal of the container run a whoami command to confirm that the container works and can make syscalls back to the Docker Host. Exit the new shell and the container. is going to be removed with a future release of Kubernetes. profile frontend and services without specified profiles. Docker Compose will shut down a container if its entry point shuts down. A devcontainer.json file in your project tells VS Code how to access (or create) a development container with a well-defined tool and runtime stack.
