Profiles can contain more granular filters based on the value of the arguments to the system call. Start a new container with the --security-opt seccomp=unconfined flag so that no seccomp profile is applied to it. You signed in with another tab or window.

When editing the contents of the .devcontainer folder, you'll need to rebuild for changes to take effect. files, Compose combines them into a single configuration. Additional information you deem important (e.g. This is extremely secure, but removes the in an environment file. In this step you removed capabilities and apparmor from interfering, and started a new container with a seccomp profile that had no syscalls in its whitelist.
