WebSeccomp filtering provides a means for a process to specify a filter for incoming system calls. issue happens only occasionally): My analysis: To mitigate such a failure, you can: If you were introducing this feature into production-like cluster, the Kubernetes project Docker uses seccomp in filter mode and has its own JSON-based DSL that allows you to define profiles that compile down to seccomp filters. The above command sends the JSON file from the client to the daemon where it is compiled into a BPF program using a thin Go wrapper around libseccomp. # array). 15853f32f67c: Pull complete One of these security mechanisms is seccomp, which Docker uses to constrain what system calls containers can run. .
