Over half way through winter and spring is nearly on-premises. While the temperatures have been icy, come get some hot new insights from our vendor portal.  It’s time for another fresh batch of exciting capabilities newly available in our application manager, our Kubernetes installer, and the vendor portal. Check out the recently shipped features and release highlights for February 2023 below.

What’s New for The Vendor Portal:

Vendor Portal: New: Improved Customer Instance Telemetry

The instance detail page helps vendor support engineers, product engineers, and anyone else on a vendor team who might be jumping into a customer engagement, quickly gain context on 

  • Instance app details
  • Kubernetes and KOTS versions
  • App uptime in time series format
  • Any recent update activity or infrastructure changes
  • Insights around instance performance like overall uptime and time-to-install

What’s New for The Application Manager:

Application Manager: Troubleshoot Log Collection Now Limits Log Sizes (v0.54.0)

Previously, pod logs containing very long lines could bloat support bundles to an unreasonable size. The size of each pod log is now limited to 5MB (configurable), in addition to the existing limits of number of lines and age.

If you want to customize the number of bytes are collecting for a specific log file. The example below changes this log file size to collect 10mb.

Application Manager: New: Use Your Own Domains to Alias the Replicated Registry and Proxy Service Endpoints (Beta) (v.1.93.1)

A vendor’s branding, and the security review process they go through with customers, can be improved by removing references to Replicated from the installation of their application. A vendor’s own domain can be used to replace references to when images are hosted in the Replicated registry, and when the app manager proxies images from an external private registry. See this this demo for more about how to use this feature yourself.

Application Manager: New: Add UDP Port Availability Preflight (Troubleshoot v0.55.0)

Troubleshoot now as the availability to test UDP port status. If you have an application using UDP be sure to leverage this new functionality to enhance your supportability. See the details here.

Application Manager: Troubleshoot Collector Updates (Troubleshoot v0.49.0)

The sysctl collector now includes virtual memory parameters. Files which previously generated ‘noise’ in results, e.g. the ‘previous’ log files from pods, can now be excluded from analysis so the results are much cleaner.

Both the Postgres and Redis collectors now support connections with TLS. Vendors wanting to use preflights and/or collectors for Redis and Postgres databases that require TLS can now use the collector.

Application Manager: Troubleshoot Stores Logs in A Consistent Manner and sbctl Support for Logs  (Troubleshoot v0.48.1)

Previously pod logs were stored in various directories within a support bundle depending on the path defined in the logs collector spec. This made it hard to discover logs, and for sbctl to show them as users expected. With this change logs are now stored in the same root directory to work with sbctl, which allows sbctl to return collected pod logs from more than just the cluster-resources collector, better meeting user expectations of how sbctl should work. For backwards compatibility, symlinks to logs are created to allow people to find logs where they used to, without needing to store those logs twice. 

Application manager: Troubleshoot textAnalyze analyzer can select files to exclude from the list of files to review (Troubleshoot v0.49.0)

Files which previously generated ‘noise’ in results, e.g. the ‘previous’ log files from pods, can now be excluded from analysis so the results are much cleaner.

If you’ve had noisy log files you want to exclude from your analyzer, you can use this to make sure the analyzer providing value. 


What’s New for the Kubernetes installer

Kubernetes Installer: New: Migrate From Weave to Flannel (v2023.01.23-0)

This migration allows a seamless transition from weave to Flannel, our new CNI of choice, for all Kubernetes installer clusters.

Update your installer specifications today to receive the latest supported networking technologies that Flannel brings to your application.

Kubernetes Installer: Rook Migration Supported From 1.0.4 to 1.10.8 (v2023.01.23-0)

This update brings kurl up to with the very latest rook version. This update is a rolling update that takes you through each minor release until you reach the latest version. Before your customers upgrade, if they were using file backed devices in rook (pre Rook v1.3),  they will need to have a unmounted block device available, as newer versions of rook do not have host file device support. If your app doesn’t need replication, hold tight for a coming details on a migration to OpenEBS that won’t require the block devices. 

What’s New for the Replicated Documentation

Replicated Documentation: Generating a Merged Support Bundle

Vendors have inquired about how customers can generate a merged support bundle, which is a support bundle generated from multiple sources (e.g., a URL, file, ConfigMap/Secret). To reduce support tickets and to help vendors self-serve their customers, we added some conceptual and procedural information in the Enterprise documentation.

Replicated Documentation: Using modular, Online, and Discoverable Troubleshoot Specifications

The vendor documentation now contains some examples about how vendors can use a modular design approach for support bundle specifications, including using online specifications and making them discoverable. This supports our goal of helping vendors to onboard successfully with Replicated.

Follow these instructions to make your support bundle generation more simple and efficient!

Replicated Documentation: Improved Table of Contents

Come see our new table of contents designed to reduce the number of clicks necessary to find the information you need. 

Replicated Documentation: Improved Documentation for Enterprise Users on Updating Embedded Cluster

We re-wrote the documentation about how to update the version of Kubernetes, the app manager (KOTS), and any kURL add-ons in embedded clusters to provide more clear, detailed instructions and conceptual information. If you are using embedded clusters be sure to read the latest documentation on keeping clusters up to date.
