D2iQ® Kommander® version 1.4.0 was released on May 5, 2021.
Kommander provides a command center for all your cloud native management needs in public IaaS, on-premises, and edge environments. Kommander provides a multi-tenant experience to create, secure, and configure Kubernetes clusters and cloud native workloads. Kommander unlocks federated cost management across multiple clusters, whether in a new Konvoy cluster or an existing 3rd party/DIY distribution installation.
In Kommander 1.3.2 and earlier versions, the Kubecost cost analyzer requests a PVC of size 0.2Gi by default, which can cause issues with provisioners requiring a minimum storage size of 1Gi. Upgrade to version 1.4.1 to resolve this issue. Refer here for more information.
Workspace Permissions Updates
In previous Kommander versions, Workspace roles were not automatically propagated to Project roles. A user with edit permissions for the Workspace did not automatically receive edit permissions to a Project inside the Workspace. Beginning with Kommander version 1.4, roles are propagated from Workspace to Project, and a user with edit permissions on the Workspace automatically had edit permissions on the Project.
Refer to the instructions in Access Control to disable this propagation.
Prior to release 1.4, Kommander required bi-directional connectivity between the Kommander management cluster and clusters that are under management. This effectively blocked several use cases, for example:
Kommander did not have direct access to the managed cluster, for example, when the cluster was on a laptop or behind a NAT gateway.
The managed cluster did not have direct access to Kommander when Kommander was on-premise and the managed cluster was in a public cloud provider environment.
The managed cluster was behind a firewall, a proxy, or resident in a DMZ.
A new component, kubetunnel, provides communication between Kommander and the managed cluster through a tunneling protocol resolving these blocked use cases. The TLS-encrypted tunnel enables you to access the cluster using SSO and to receive alerts, metrics, and kubecost data.

Catalog Workload Certification
D2iQ now certifies workloads for use with Kommander. All workloads that are tested and certified for successful configuration and provisioning on Konvoy are flagged in Kommander with a certification icon. For more information, see Project Platform Services.
The Projects tab now shows all of the current Helm Release charts, their chart version, and the names of the clusters. For more information, see Project Deployments.
Docker hub rate limiting
Docker Hub announced an update to image pull policies in August, 2020. This results in the need to change cluster configurations to accommodate new account structures that enable image pull rate limiting.
Rate limiting happens on a per-pull basis regardless of whether the pulled image is owned by a paid user. This means D2iQ, as owner of most images used in Konvoy, does not have any influence if your current address is rate-limited or not. Konvoy does not have a strict dependency on Docker Hub accounts or plans.
For more information on addressing this limit, see Docker hub rate limits.
