Hi @alappin10, sorry for the delay.
Note that we do not support f1-micro instances for Bitnami multi-tier images. In fact, Google Cloud does not let you select an instance size with less than 1GB memory (f1-micro has 0.6GB):
In any case, we were able to reproduce this issue when we had an instance with 1GB of memory. We will let you know once we find anything.
In the meantime, we launched a cluster with 2 nodes and 1.25GB of memory and it went well, so you could try again with an instance size that has at least 1.25GB of memory.
