通过以上步骤,你应该能够解决 “Can't attach to the process: ptrace(PTRACE_ATTACH, ..) failed for 1: Operation not permitted” 的问题。如果问题仍然存在,建议进一步检查 Docker 的配置和权限设置。
echo 0 > /proc/sys/kernel/yama/ptrace_scope 重启之后失效。 (2)永久解决 编辑/etc/sysctl.d/10-ptrace.conf这个文件,若没有,创建之。设置(默认是1) kernel.yama.ptrace_scope = 0 这样下次启动时会生效。 参考: https://rajeeshknambiar.wordpress.com/2015/07/16/attaching-debugger-and-ptrace_scope/...

Turn send_sig_info(SIGSTOP) into send_signal_locked(SIGSTOP) and move it from ptrace_attach() to ptrace_set_stopped(). This looks more logical and avoids lock(siglock) right after unlock(). Link: https://lkml.kernel.org/r/20240122171631.GA29844@redhat.com Signed-off-by: Oleg Nesterov...

类似于 jmap 这些 JDK 工具依赖于 Linux 的 PTRACE_ATTACH,而是 Docker 自 1.10 在默认的 seccomp 配置文件中禁用了 ptrace。 主要提及三种: 1.1 –security-opt seccomp=unconfined 直接关闭 seccomp 配置或者将ptrace添加到允许的名单中。用法: docker run --security-opt seccomp:unconfined ... 官方文档提到...
