v1.6.0

Release Date: November 14, 2019

Features

This section describes new features and changes in this release.

PKS Control Plane and API

Enterprise PKS v1.6.0 updates include:

• Enables operators to upgrade multiple Kubernetes clusters simultaneously and to designate specific upgrade clusters as canary clusters. For more information about multiple cluster upgrades, see Upgrade Clusters in Upgrading Clusters.
• Adds a new UAA scope, pks.clusters.admin.read, for Enterprise PKS users. For information about UAA scopes, see UAA Scopes for Enterprise PKS Users and Managing Enterprise PKS Users with UAA.
• Provides experimental integration with Tanzu Mission Control. For more information, see Tanzu Mission Control Integration.
• Enables operators to limit the total number of clusters a user can provision in Enterprise PKS. For more information about quotas, see Managing Resource Usage with Quotas and Viewing Usage Quotas.
• Enables operators to configure a single Kubernetes cluster with a specific Docker Registry CA certificate. For more information about configuring a cluster with a Docker Registry CA certificate, see Configuring Enterprise PKS Clusters with Private Docker Registry CA Certificates (Beta).
• Updates the pks delete-cluster PKS CLI command so that all cluster objects, including NSX-T networking objects, are deleted without the need to use the bosh delete deployment command to remove failed cluster deletions.

Kubernetes Control Plane

Enterprise PKS v1.6.0 updates include:

• Increases the Worker VM Max in Flight default value from 1 to 4 in the PKS API configuration pane, which accelerates cluster creation by allowing up to four new nodes to be provisioned simultaneously. The updated default value is only applied during new Enterprise PKS installation and is not applied during an Enterprise PKS upgrade. If you are upgrading Enterprise PKS from a previous version and want to accelerate multi-cluster provisioning, you can increase the value of Worker VM Max in Flight manually.

PKS Monitoring and Logging

Enterprise PKS v1.6.0 updates include:

• Redesigns the Logging and Monitoring panes of the Enterprise PKS tile and renames them to Host Monitoring and In-Cluster Monitoring. For information about configuring these panes, see the Installing Enterprise PKS topic for your IaaS.
• Adds the Max Message Size field in the Host Monitoring pane. This allows you to configure the maximum number of characters of a log message that is forwarded to a syslog endpoint. This feature helps ensure that log messages are not truncated at the syslog endpoint. By default, the Max Message Size field is 10,000 characters. For more information, see Host Monitoring in the Installing Enterprise PKS topic for your IaaS.
  
• Adds the Include kubelet metrics setting. This enables operators to collect workload metrics across all Kubernetes clusters. For more information, see Host Monitoring in the Installing Enterprise PKS topic for your IaaS.
• Adds support for Fluent Bit output plugins to log sinks. For information about configuring Fluent Bit output plugins, see Create a ClusterLogSink or LogSink Resource with a Fluent Bit Output Plugin in Creating and Managing Sink Resources.
• Adds support for filtering logs and events from a ClusterLogSink or LogSink resource. For more information, see Filter Sinks in Creating and Managing Sink Resources.
  

Windows on PKS

Enterprise PKS v1.6.0 updates include:

• Adds support for floating Windows stemcells on vSphere. For information about Kubernetes clusters with Windows workers in Enterprise PKS, see Configuring Windows Worker-Based Kubernetes Clusters (Beta).
• Enables operators to configure the location of the Windows pause image. For information about configuring Kubelet customization - Windows pause image location, see Plans in Configuring Windows Worker-Based Kubernetes Clusters (Beta).

PKS with NSX-T Networking

Enterprise PKS v1.6.0 updates include:

• NSX Error CRD lets cluster managers and users view NSX errors in Kubernetes resource annotations, and use the command kubectl get nsxerror to view the health status of NSX-T cluster networking objects (NCP v2.5.0+). For more information, see Viewing the Health Status of Cluster Networking Objects (NSX-T only).
• DFW log control for dropped traffic lets cluster administrators define network profile to turn on logging and log any dropped or rejected packet by NSX-T distributed firewall rules (NCP v2.5.0+). For more information, see Defining Network Profiles for NCP Logging.
• Load balancer and ingress resource capacity observability using the NSXLoadBalancerMonitor CRD lets cluster managers and users use the command kubectl get nsxLoadBalancerMonitors to view a health score that reflects the current performance of the NSX-T load balancer service, including usage, traffic, and current status (NCP v2.5.1+). For more information, see Ingress Scaling (NSX-T only).
• Ingress scale out using the LoadBalancer CRD lets cluster managers scale out the NSX-T load balancer for ingress routing (NCP v2.5.1+). For more information, see Ingress Scaling (NSX-T only).
• Support for Ingress URL Rewrite. For more information, see Using Ingress URL Rewrite.
• Support for Active–Active Tier-0 router configuration when using a Shared-Tier-1 topology.

Product Snapshot

Upgrade Path

The supported upgrade paths to Enterprise PKS v1.6.0 are from Enterprise PKS v1.5.0 and later.

Breaking Changes

Enterprise PKS v1.6.0 has the following breaking changes:

Persistent Volume Data Loss with Worker Reboot

With old versions of Ops Manager, PKS worker nodes with persistent disk volumes may get stuck in a startup state and lose data when they are rebooted manually from the dashboard or automatically by vSphere HA.

This issue is fixed in the following Ops Manager versions:

• v2.8.0+
• v2.7.6+
• v2.6.16+

For all PKS installations that host workers using persistent volumes, Pivotal recommends upgrading to one of the Ops Manager versions above.

Enterprise PKS Removes Sink Commands in the PKS CLI

Enterprise PKS removes the following Enterprise PKS Command Line Interface (PKS CLI) commands:

• pks create-sink
• pks sinks
• pks delete-sink

You can use the following Kubernetes CLI commands instead:

• kubectl apply -f YOUR-SINK.yml
• kubectl get clusterlogsinks
• kubectl delete clusterlogsink YOUR-SINK

For more information about defining and managing sink resources, see Creating and Managing Sink Resources.

Changes to PKS API Endpoints

This release moves the clusters, compute-profiles, quotas, and usages PKS API endpoints from v1beta1 to v1. v1beta1 is no longer supported for these endpoints. You must use v1. For example, instead of https://YOUR-PKS-API-FQDN:9021/v1beta1/quotas, use https://YOUR-PKS-API-FQDN:9021/v1/quotas.

Known Issues

Enterprise PKS v1.6.0 has the following known issues.

Your Kubernetes API Server CA Certificate Expires Unless You Regenerate It

Symptom

Your Kubernetes API server’s tls-kubernetes-2018 certificate is a one-year certificate instead of a four-year certificate.

Explanation

When you upgraded from PKS v1.2.7 to PKS v1.3.1, the upgrade process extended the lifespan of all PKS CA certificates to four years, except for the Kubernetes API server’s tls-kubernetes-2018 certificate. The tls-kubernetes-2018 certificate remained a one-year certificate.

Unless you regenerate the tls-kubernetes-2018 certificate it retains its one-year lifespan, even through subsequent Enterprise PKS upgrades.

Workaround

If you have not already done so, you should replace the Kubernetes API server’s one-year tls-kubernetes-2018 certificate before it expires. For information about generating and applying a new four-year tls-kubernetes-2018 certificate, see How to regenerate tls-kubernetes-2018 certificate when it is not regenerated in the upgrade to PKS v1.3.x in the Pivotal Knowledge Base.

Cluster Upgrade Does Not Upgrade Kubernetes Version on Windows Workers

When PKS clusters are upgraded, Windows worker nodes in the cluster do not upgrade their Kubernetes version. The master and Linux worker nodes in the cluster do upgrade their Kubernetes version as expected.

When the Kubernetes version of a Windows worker does not exactly match the version of the master node, the cluster still functions. kube-apiserver has no restriction on lagging patch bumps.

PKS clusters upgrade manually with the pks upgrade-cluster command, or automatically with PKS upgrades when the Upgrade all clusters errand is set to Default (On) in the PKS tile Errands pane.

Network Profile for “pks update-cluster” Does Not Use the Defaults from the Original Cluster Manifest

Note: This issue is resolved in Enterprise PKS v1.6.1.

Symptom

The Network profile for pks update-cluster uses contents that are being updated and not using the defaults from the original cluster manifest.

Explanation

The pks update-cluster operation sets the subnet_prefix to 0 in the ncp.ini file when the network-profile has pod_ip_block_ids set but it does not have pod_subnet_prefix.

Workaround

When creating the network profile to be used for update, include all the below fields. Then update-cluster with the network profile should work.

{
    "name": "np",
    "parameters": {
        "t0_router_id": "c501f114-870b-4eda-99ac-966adf464452",
        "fip_pool_ids": ["b7acbda8-46de-4195-add2-5fb11ca46cbf"],
        "pod_ip_block_ids": ["b03bff60-854b-4ccb-9b2b-016867b319c9","234c3652-69e7-4365-9627-8e0d8d4a6b86"],
        "pod_subnet_prefix": 24,
        "single_tier_topology": false
    }
}

Azure Default Security Group Is Not Automatically Assigned to Cluster VMs

Symptom

You experience issues when configuring a load balancer for a multi-master Kubernetes cluster or creating a service of type LoadBalancer. Additionally, in the Azure portal, the VM > Networking page does not display any inbound and outbound traffic rules for your cluster VMs.

Explanation

As part of configuring the Enterprise PKS tile for Azure, you enter Default Security Group in the Kubernetes Cloud Provider pane. When you create a Kubernetes cluster, Enterprise PKS automatically assigns this security group to each VM in the cluster. However, on Azure the automatic assignment may not occur.

As a result, your inbound and outbound traffic rules defined in the security group are not applied to the cluster VMs.

Workaround

If you experience this issue, manually assign the default security group to each VM NIC in your cluster.

Cluster Creation Fails When First AZ Runs Out of Resources

Symptom

If the first availability zone (AZ) used by a plan with multiple AZs runs out of resources, cluster creation fails with an error like the following:

L Error: CPI error 'Bosh::Clouds::CloudError' with message 'No valid placement found for requested memory: 4096

Explanation

BOSH creates VMs for your Enterprise PKS deployment using a round-robin algorithm, creating the first VM in the first AZ that your plan uses. If the AZ runs out of resources, cluster creation fails because BOSH cannot create the cluster VM.

For example, if you have three AZs and you create two clusters with four worker VMs each, BOSH deploys VMs in the following AZs:

In this scenario, AZ1 has twice as many VMs as AZ2 or AZ3.

Cluster Creation Fails with Long Network Profile

Note: This issue is resolved in Enterprise PKS v1.6.1.

Creating a cluster with a long network profile, such as with multiple pod_ip_block_ids values, causes an error Data too long for column 'nsxt_network_profile'.

Azure Worker Node Communication Fails after Upgrade

Symptom

Outbound communication from a worker node VM fails after upgrading Enterprise PKS.

Explanation

Enterprise PKS uses Azure Availability Sets to improve the uptime of workloads and worker nodes in the event of Azure platform failures. Worker node VMs are distributed evenly across Availability Sets.

Azure Standard SKU Load Balancers are recommended for the Kubernetes control plane and Kubernetes ingress and egress. This load balancer type provides an IP address for outbound communication using SNAT.

During an upgrade, when BOSH rebuilds a given worker instance in an Availability Set, Azure can time out while re-attaching the worker node network interface to the back-end pool of the Standard SKU Load Balancer.

For more information, see Outbound connections in Azure in the Azure documentation.

Workaround

You can manually re-attach the worker instance to the back-end pool of the Azure Standard SKU Load Balancer in your Azure console.

Error During Individual Cluster Upgrades

Symptom

While submitting a large number of cluster upgrade requests using the pks upgrade-cluster command, some of your Kubernetes clusters are marked as failed.

Explanation

BOSH upgrades Kubernetes clusters in parallel with a limit of up to four concurrent cluster upgrades by default. If you schedule more than four cluster upgrades, Enterprise PKS queues the upgrades and waits for BOSH to finish the last upgrade. When BOSH finishes the last upgrade, it starts working on the next upgrade request.

If you submit too many cluster upgrades to BOSH, an error may occur, where some of your clusters are marked as FAILED because BOSH can start the upgrade only within the specified timeout. The timeout is set to 168 hours by default. However, BOSH does not remove the task from the queue or stop working on the upgrade if it has been picked up.

Solution

If you expect that upgrading all of your Kubernetes clusters takes more than 168 hours, do not use a script that submits upgrade requests for all of your clusters at once. For information about upgrading Kubernetes clusters provisioned by Enterprise PKS, see Upgrading Clusters.

Kubectl CLI Commands Do Not Work after Changing an Existing Plan to a Different AZ

Symptom

After you update the AZ of an existing plan, kubectl CLI commands do not work for your clusters associated with the plan.

Explanation

This issue occurs in IaaS environments that do not support attaching a disk across multiple AZs.

When the plan of an existing cluster changes to a different AZ, BOSH migrates the cluster by creating VMs for the cluster in the new AZ and removing your cluster VMs from the original AZ.

On an IaaS that does not support attaching VM disks across AZs, the disks BOSH attaches to the new VMs do not have the original content.

Workaround

If you cannot run kubectl CLI commands after reconfiguring the AZ of an existing cluster, contact Support for assistance.

Applying Changes Fails If Plan 8 Is Enabled

Note: This issue is resolved in Enterprise PKS v1.6.1.

Symptom

After you click Apply Changes on the Ops Manager Installation Dashboard, the following error occurs: Cannot generate manifest for product Enterprise PKS.

Explanation

This error occurs if Plan 8 is enabled in your Enterprise PKS v1.6.0 tile.

Workaround

Disable Plan 8 in the Enterprise PKS tile and move your plan settings to a plan that is available for configuration, for example, Plan 9 or 10.

To disable Plan 8:

1. In Plan 8, select Plan > Inactive.
2. Click Save.

One Plan ID Longer than Other Plan IDs

Symptom

One of your plan IDs is one character longer than your other plan IDs.

Explanation

In Enterprise PKS, each plan has a unique plan ID. A plan ID is normally a UUID consisting of 32 alphanumeric characters and 4 hyphens. However, the Plan 4 ID consists of 33 alphanumeric characters and 4 hyphens.

Solution

You can safely configure and use Plan 4. The length of the Plan 4 ID does not affect the functionality of Plan 4 clusters.

If you require all plan IDs to have identical length, do not activate or use Plan 4.

Kubernetes Cluster Name Limitation for Tanzu Mission Control Integration

Tanzu Mission Control integration cannot attach Tanzu Mission Control to Kubernetes clusters that have uppercase letters in their names.

Symptom

Clusters that you create with pks create-cluster do not appear in the Tanzu Mission Control, even though you configured Tanzu Mission Control integration as described in Integrate Tanzu Mission Control.

Explanation

The regex pattern that parses cluster names in Tanzu Mission Control integration fails with names that contain uppercase letters.

Solution

When running pks create-cluster to create clusters that you want to track in Tanzu Mission Control, pass in names that contain only lowercase letters and numbers.

Enterprise PKS Creates a Linux Cluster When You Expect a Windows Cluster

Note: This issue is resolved in Enterprise PKS v1.6.1.

Symptom

When you create an Enterprise PKS cluster using either Plan 11, 12 or 13 the cluster is created as a Linux cluster instead of a Windows cluster.

Explanation

When you create an Enterprise PKS cluster using either Plan 11, 12 or 13 a Windows cluster should be created. If you are using Enterprise PKS v1.6 with Operations Manager v2.7 a Linux cluster is created instead.

Saving UAA Tab Settings Fails With Error: ‘InvalidURIError bad URI’

Symptom

When you save your UAA tab with LDAP Server selected and multiple LDAP servers specified, you receive the error: URI::InvalidURIError bad URI(is not URI?):LDAP URLs.

Explanation

When you configure the UAA tab with multiple LDAP servers your settings will fail to validate when using the following Ops Manager releases:

Workaround

To resolve this issue see the following:

Windows Worker Clusters Fail to Upgrade to v1.6

Symptoms

During your upgrade from Enterprise PKS v1.5 to Enterprise PKS v1.6 a Windows worker VM fails to upgrade, as evidenced by:

• The command line outputs an error Failed jobs: docker-windows.
• The Windows worker VM disappears from the output of kubectl get nodes.
• The command line shows the status failed and the action UPGRADE for the cluster that contains the worker.
• The log shows an entry \docker\dockerd.exe: Access is denied.

Explanation

Between PKS v1.5 and v1.6, the name of the Docker service changed from docker to docker-windows, but your environment continues to use the old Docker service name and paths. The incompatible service name and pathing causes a Windows worker upgrade to fail.

If your cluster has multiple Windows workers, this issue does not incur downtime . Before BOSH attempts to upgrade a Windows worker, it moves the worker’s apps to other Windows workers in the cluster. When the upgrade fails, BOSH stops the cluster upgrade process and the other Windows workers continue running at the earlier version.

Workaround

After upgrading to Enterprise PKS v1.6 and your Windows worker clusters have failed to upgrade, complete the following steps:

1. Upload a vSphere stemcell v2019.8 or later for Windows Server version 2019 to your Enterprise PKS tile.
   
2. To upgrade your Windows worker clusters, perform one of the following:
   • Enable the Upgrade all clusters errand setting and deploy the PKS tile. For more information about configuring the Upgrade all clusters errand and deploying the Enterprise PKS tile, see Modify Errand Configuration in the Enterprise PKS Tile in Upgrading Clusters.
   • Run pks upgrade-cluster or pks upgrade-clusters on your failed Windows worker cluster(s). For more information about upgrading specific Enterprise PKS clusters, see Upgrade Clusters in Upgrading Clusters.

502 Bad Gateway After OIDC Login

Symptom

You experience a “502 Bad Gateway” error from the NSX load balancer after you log in to OIDC.

Explanation

A large response header has exceeded your NSX-T load balancer maximum response header size. The default maximum response header size is 10,240 characters and should be resized to 50,000.

Workaround

If you experience this issue, manually reconfigure your NSX-T request_header_size and response_header_size to 50,000 characters. For information about configuring NSX-T default header sizes, see OIDC Response Header Overflow in the Pivotal Knowledge Base.

NSX-T Pre-Check Errand Fails Due to Edge Node Configuration

Symptom

You have configured your NSX-T Edge Node VM as medium size, and the NSX-T Pre-Check Errand fails with the following error: “ERROR: NSX-T Precheck failed due to Edge Node … no of cpu cores is less than 8”.

Explanation

The NSX-T Pre-Check Errand is erroneously returning the “cpu cores is less than 8” error.

Solution

You can safely configure your NSX-T Edge Node VMs as medium size and ignore the error.

Character Limitations in HTTP Proxy Password

For vSphere with NSX-T, the HTTP Proxy password field does not support the following special characters: & or ;.

Configuring Enterprise PKS Management Console Integration with VMware vRealize Log Insight

Symptom

Enterprise PKS Management Console appliance sends logs to VMware vRealize Log Insight over HTTP, not HTTPS.

Explanation

When you deploy the Enterprise PKS Management Console appliance from the OVA, if you require log forwarding to vRealize Log Insight, you must provide the port on the vRealize Log Insight server on which it listens for HTTP traffic. Do not provide the HTTPS port.

Workaround

Set the vRealize Log Insight port to the HTTP port. This is typically port 9000.

Deploying Enterprise PKS to an Unprepared NSX-T Data Center Environment Results in Flannel Error

Using BOSH CLI from Operations Manager VM

Symptom

The BOSH CLI client bash command that you obtain from the Deployment Metadata view does not work when logged in to the Operations Manager VM.

Explanation

The BOSH CLI client bash command from the Deployment Metadata view is intended to be used from within the Enterprise PKS Management Console appliance.

Workaround

To use the BOSH CLI from within the Operations Manager VM, see Connect to Operations Manager.

From the Ops Manager VM, use the BOSH CLI client bash command from the Deployment Metadata page, with the following modifications:

• Remove the clause BOSH_ALL_PROXY=xxx
• Replace the BOSH_CA_CERT section with BOSH_CA_CERT=/var/tempest/workspaces/default/root_ca_certificate

Run pks Commands against the PKS API Server

Explanation

The PKS CLI is available in the Enterprise PKS Management Console appliance.

Workaround

To be able to run pks commands against the PKS API Server, you must first log to PKS using the following command syntax pks login -a fqdn_of_pks ....

To do this, you must ensure either of the following:

• The FQDN configured for the PKS Server is resolvable by the DNS server configured for the Enterprise PKS Management Console appliance, or
• An entry that maps the Floating IP assigned to the PKS Server to the FQDN exists on /etc/hosts in the appliance. For example: 192.168.160.102 api.pks.local.
