Large increase in the number of nodes in the cluster after linkerd rollout

After rolling out linkerd, the number of nodes in our cluster has jumped from 23 to 55. They’re relatively small nodes (8CPU and 28GB), but this seems like a large jump, even with the extra CPU and memory needed by the linkerd sidecars.

Is this increase in the cluster size expected after rolling out linkerd? Or should we be looking for another change that could’ve caused this issue?
