Totally agree. In trying to make self contained debug environments like
containers, to help users with developers tackle tricky problems:
Example:
$ podman run -d --rm -p 2345 --cap-add CAP_SYS_PTRACE --name mdb-debug -e
MARIADB_ALLOW_EMPTY_ROOT_PASSWORD=1
quay.io/mariadb-foundation/mariadb-debug:10.5
1f2f0246ad656dad10be8cacedf312f94f7b98651906f29d09f07dbf048c4f70
$ podman port mdb-debug 2345
0.0.0.0:44663
$ podman exec -ti mdb-debug gosu mysql gdbserver --attach :2345 1
Attached; pid = 1
Listening on port 2345
$ gdb
