How were the bushido of the samurai and the code of chivalry of knights similar?

Bushido is a term translated as "the way of the warrior". The code of chivalry complies with an ethical code based on ecclesiastical ethics because they are knights of Christ. Both of them were similar because they were based on an ethic for the common good.

Explanation:

For Samurais the Bushido is a strict and particular ethical code to which many samurai gave their lives, which demanded loyalty and honor until death. It is said that since childhood, the bushidō was instilled in the Japanese of the ruling class even before taking off from the mother's chest.

For Knights the code of chivalry governed their behavior. They should love the country they were born in, don't surrender to the enemy, war against infidels, fulfill feudal duties, be faithful and do not lie, be generous, keep good against injustice and evil.
