Hello and welcome Little Bird
Honeysuckle, being a woodland and hedgerow plant, likes it's face in the sun and a deep cool root run and will suffer from powdery mildew if its roots dry out.
If grown in a container it needs to be really large, deep and kept in the shade, and the soil needs to be kept moist (not wet, but moist).
I suggest that John Innes No 3 loam based compost is the most suitable, and I would add a good helping of organic material to this I'd use well rotted farmyard manure and leaf mould.
