Whenever you do any change to a Capsule, it will happen as a Rollout of a new configuration. A Rollout is thus the operation of deploying and running a given configuration of the Capsule. When a change is made, e.g. the number of replicas is changed, a new Rollout is automatically initiated, succeeding the currently running.

This Rollout will run until it's being replace by a new one.


All Rollouts captures the full configuration, meaning Rollouts serves as an immutable historic view of all changes made to the system, including the resources written to Kubernetes. Because of this, Rollouts naturally works as Rollback points for revering changes made to the system.


To perform a Rollback to a previous version, simply select the Rollout in question and click Rollback. Because changes only can happen as a Rollouts, the Rollback itself will happen as a new Rollout.


A Rollout has 3 basic stages in its lifecycle:

  • Configuration: In this stage, the new resources for the Capsule is generated and being applied. In the basic setup, that means writing it directly to Kubernetes. In a GitOps setup, this is where the new files are written and committed to Git.
  • Creating resources: This stage stars when the new resources has been written to Kubernetes. From here a number of Operator-generated resources is further created.
  • Running: When all resources are created, the Running stage starts. This tracks the health of the Capsule in the cluster, with initially ensuring all instances are being upgraded.
