遇到问题五 java.lang.UnsupportedOperationException: seccomp unavailable: CONFIG_SECCOMP not compiled into kernel, CONFIG_SECCOMP and CONFIG_SECCOMP_FILTER are needed
网上资料是这样说的
seccomp是linux kernel从2.6.23版本开始所支持的一种安全机制，seccomp（安全计算模式的简称）是Linux内核中的计算机安全设施。 它被合并到2005年3月8日发布的内核版本2.6.12中的Linux内核主线上。[1] seccomp允许进程单向转换为“安全”状态，除了exit（），sigreturn（），read（）和write（）之外，它不能对已经打开的文件描述符进行任何系统调用。 如果它尝试任何其他系统调用，内核将使用SIGKILL或SIGSYS [2] [3]终止进程。 从这个意义上说，它不会虚拟化系统的资源，而是将过程与它们完全隔离开来。
环境的内核是
