I'm playing a way of the open hand Monk, I use flurry of blows and using a ki point I can opt to shove my target up to 15 ft.
If I pushed it to within 5ft of a fighter in my party, could they use their reaction to make an attack of opportunity? Or do opportunity attacks only occur when leaving a characters reach?
You can make an opportunity attack when a hostile creature that you can see moves out of your reach.
The exception to this is if you have the feat polearm master:
While you are wielding a glaive, halberd, pike, or quarterstaff, other creatures provoke an opportunity attack from you when they enter the reach you have with that weapon.
Even polearm master won't let you take an opportunity attack against the shoved enemy since in order to qualify for an opportunity attack the enemy has to move using their action, reaction, or movement:
You also don’t provoke an opportunity attack when you Teleport or when someone or something moves you without using your Movement, action, or reaction.
A shoved enemy is moved by your action and without using any of their actions or movement. So it will not provoke an opportunity attack.
