Pistachio trees are not particularly suitable as container plants. However, they can be grown in containers (the bigger the tree, the bigger your container will need to be) until they reach about 3-5 years old, at which point you should plant it in a permanent location outdoors. Mature pistachios have an extremely long tap root, requiring deep, well-draining soil that containers cannot provide. Dig the planting hole as deep and wide as its current pot.
