Pyracantha 'Soleil D'Or' HELP!

Couple of questions please.
Does anyone have any simple instructions or video links that I can use to train my Pyracantha’s against a brick wall without using any wires or supports?
My OH won’t allow me to drill into his newly built brick shed so that I can hang supports.
I want to put them into pots shown. Are these large enough for them to be trained and left in for a few years? I have the the orange glow and a red column.
Thank you for your help.

Could you put together larger wooden and lined planters and incorporate some kind of frame to train them to? Not ideal but better than nothing.
If your OH's shed is any good it should be able to cope with a couple of vine eyes and some wire surely.
The other option is to stick canes down at 1 ft intervals into the soil behind the plant and tie the new branches into it, again loosely so you can cut them off and pull the canes out. But the issue is, you want to grow into pots. I can't see that working. You need to plant them into really large containers or into some type of raised bed. That way, the trellis/canes can be slotted and buried into the soil as support behind the shrub, and then removed once the shrub has established the main frame for the branches. That's possibly 3-4 years on.
You’ve given me some really good ideas. Noticed that whenever I post a question it is mostly you 3 lovely people that always offer your amazing advice. Now just have to persuade my OH to let me put some eye hooks in the shed or get me the brick clips. Failing that I’ll have to go with Borderline’s idea.
I'd agree with Ppauper though - those troughs aren't going to be big enough - even though pyracanthas are tough, you'll find it hard to keep them healthy and thriving in such small containers. Even a really big pot would be better if you can't get them in the goround
