  MAXI J1535-571 is a Galactic black hole candidate X-ray binary that was
discovered going into outburst in 2017 September. In this paper, we present
comprehensive radio monitoring of this system using the Australia Telescope
Compact Array (ATCA), as well as the MeerKAT radio observatory, showing the
evolution of the radio jet during its outburst. Our radio observations show the
early rise and subsequent quenching of the compact jet as the outburst
brightened and then evolved towards the soft state. We constrain the compact
jet quenching factor to be more than 3.5 orders of magnitude. We also detected
and tracked (for 303 days) a discrete, relativistically-moving jet knot that
was launched from the system. From the motion of the apparently superluminal
knot, we constrain the jet inclination (at the time of ejection) and speed to
$\leq 45^{\circ}$ and $\geq0.69$c, respectively. Extrapolating its motion back
in time, our results suggest that the jet knot was ejected close in time to the
transition from the hard intermediate state to soft intermediate state. The
launching event also occurred contemporaneously with a short increase in X-ray
count rate, a rapid drop in the strength of the X-ray variability, and a change
in the type-C quasi-periodic oscillation (QPO) frequency that occurs $>$2.5
days before the first appearance of a possible type-B QPO.
