You may compile GDB inside the docker (or share a volume of a compiled GDB into
the docker from the host). Then you can put it ahead in PATH so it's picked up
before
/venv/bin/gdb . E.g. if the compiled GDB with debug info is in the home dir you
can:

```bash
cd ~
PATH=$(pwd):$PATH ./exploit.py
```

Alternatively, you can:
```bash
pip install -U pwntools
```
and put
```python
context.gdb_binary = "path/to/my/gdb"
```
near the top of the `./exploit.py` file. In this case you don't need to touch
PATH.

I'm on arch, so https://debuginfod.archlinux.org/ , though not sure if the
debug info
for packages that get updated is kept.
