Fluent operator: a Swiss Army knife for cloud native log management

With the rapid development of cloud native technology and the continuous iteration of technology, higher requirements are put forward for log collection, processing and forwarding. The log scheme under the cloud native architecture is very different from the log architecture design based on physical machine or virtual machine scenario. As a graduation project of CNCF, fluent bit is undoubtedly one of the preferred solutions to solve the logging problem in cloud environment. However, there is a certain threshold for the installation, deployment and configuration of fluent bit in kubernetes, which increases the user’s use cost.

Harbor v2. 5.0 introduction of cosign

Artifact signature and signature verification are key security functions that allow you to verify the integrity of the finished product. Harbor supports content trust through its integration with notary and cosign.

Harbor v2. 5 integrates support for cosign, an OCI finished product signature and verification solution, which is part of the sigstore project.

A key feature of the combination of cosign and harbor is the ability to use harbor’s copy function to copy signatures and their related signed products. This means that if a replication rule is applied to a signed finished product, Harbo will apply the replication rule to the signature as it applies to the signed finished product.

Tanzu application platform version 1.1 release

Launched by VMware, Tanzu application platform is designed to help users quickly build and deploy software on any public cloud or local kubernetes cluster. Tanzu application platform provides a rich set of developer tools and a pre paved path for enterprises supporting production to develop revenue generating applications faster by reducing the complexity of developer tools.

Version 1.1 provides a number of new features that enable enterprises to accelerate time to value, simplify the user experience, build a stronger security posture, and protect the investments they have made. These leading capabilities enable enterprises to:

  • Accelerate workload deployment across multiple clusters and gain cross environment visibility;
  • Using the installation configuration file significantly simplifies the platform deployment process;
  • With the help of the ability of software supply chain to use pre built container image to improve agility;
  • When the workload moves in the supply chain, you can view the workload status immediately;
  • Build a strong security foundation with consistent role-based access control (RBAC).

Kubernetes 1.24 release postponed

After a period of discussion, the release team decided to postpone the scheduled release date of kubernetes 1.24 to Tuesday, May 3, 2022. This is two weeks later than the original release date of Tuesday, April 19, 2022.

This is the result of preventing the release of bugs. The bug will be fixed in the latest minor version of golang go 1.18.1 and is expected to be released later today. Due to the delay of go release, the release team has taken measures to extend the scheduled release date of kubernetes by two weeks to allow sufficient time for testing and stabilization.

The updated schedule is now:

Tuesday, April 19, 1.24.0-rc 0

Tuesday, April 26, 1.24.0-rc 1。

1.24.0 was officially released on Tuesday, May 3.

Flagger adds gateway API support

Flag version 1.19.0 brings support for the kubernetes gateway API.

Flagger is a progressive delivery tool that automates the release process for applications running on kubernetes. It reduces the risk of introducing new software versions into production by gradually transferring traffic to new versions, measuring indicators and running consistency tests at the same time.

Thanks to the increased support for the gateway API, flagger can now work with all implementations, which means that from today on, these are native support: contour, emissary progress, Google kubernets engine, haproxy progress, hashicorp, consume, istio, Kong and traifik.

The flagger team has successfully tested contour and istio using the v1beta2 gateway API. From flag v1 Beginning with 19, the gateway API is part of an end-to-end test suite implemented using contour.
