warning: Error disabling address space randomization: Operation not permitted

Question

what have i done wrong (or didn\'t do) that gdb is not working properly for me?

root@6be3d60ab7c6:/# cat minimal.c 
int main()
{
  int i = 1337;         


        

Answer 1

Building on wisbucky's answer (thank you!), here are the same settings for Docker compose:

security_opt:
  - seccomp:unconfined
cap_add:
  - SYS_PTRACE

The security option seccomp:unconfined fixed the address space randomization warnings.

The capability SYS_PTRACE didn't seem to have a noticeable effect even though the Docker documentation states that SYS_PTRACE is a capability that is "not granted by default". Perhaps I don't know what to look for.
