Is it possible to increase the number of nodes to more than 10 on Docker Cloud?

Article ID: KB000391

Question

  • Is it possible to increase the number of nodes to more than 10 on Docker Cloud?
  • Is it possible to increase the size of nodes in an existing cluster on Docker Cloud? (e.g. from a t2.small to m4.large)

Answer

It is possible to increase the maximum number of nodes on Docker Cloud. However, it is not possible to increase the number of nodes per cluster currently.

All the quotas on your account page (https://cloud.docker.com/account/#quota) are qualified for adjustment by opening a support case.

As for increasing the size of nodes in an existing cluster, the only method to achieve that currently is to rebuild the cluster as the node size can only be adjusted during cluster creation.
