m3db/m3db-operator v0.10.0

on GitHub

0.10.0 adds initial support for safe, graceful cluster upgrades. See the upgrade
docs for more info.

This release also includes documentation enhancements, and adds the coldWritesEnabled field on namespaces to allow
enabling M3DB cold writes.

Finally, this release includes two new API fields to make it easier for users to manage their clusters:

1. A new freeze field on clusters allows a user to stop all operations on a cluster while potentially performing
   manual changes.

2. The new externalCoordinator.serviceEndpoint field allows controlling the cluster via a coordinator in another
   namespace, allowing users to have a single coordinator responsible for serving m3admin APIs for all clusters across
   any namespace.

   • WARNING: The minumum required M3 version to use with this field is v0.15.9, which includes a fix for managing
     namespaces in environments other than that for which the coordinator is provisioned.

Breaking Changes

0.10.0 makes the default pod management policy for StatefulSets created by the operator
Parallel. This
should be transparent to most users, but means that when new pods are added to a cluster, or pods are manually deleted,
they will all be recreated at once rather than after each has bootstrapped. This should lead to faster upgrades and
cluster resizing operations.
