v0.7.0

Feature:

• Multi k8s cluster management capability, requiring only one set of management surfaces to manage multiple clusters;

• Expose the configuration of the traffic injection executor #145

BugFix:

• Fix jvm injection failure problem #127

• Fix the problem that the container memory filling will be automatically GCed in 3 minutes. #108
• Front-end image package size optimization

v0.6.0

In this release, support fault capabilities such as DNS fault and log injection, and the visual orchestration interface provides support for various nodes such as traffic injection and measurement, providing support capabilities for automated chaos engineering

Enhancements

• User interface orchestration interface supports measure engine nodes and traffic injection nodes #62
• Supports offline deployment solutions and provides tools to import internal image registry with one click #106

• The CR of the measurement engine supports recording the time point when the condition is met for the first time #86
• Support injection capabilities related to DNS anomalies: DNS record injection, DNS server address injection #85
• Implement a memory injection method that does not rely on container directories at all #71 #94

Bug Fixes

• Fixed user interface failure to support memory injection in absolute value mode #84
• Fixed the problem that the fault injection capabilities of modules such as file, process, and mem depended on the container/bin/bash command #71
• Fixed the calculation method of container memory usage based on the /proc directory and changed it to based on the host's /sys/fs/cgroup directory #94

v0.5.2

This release mainly supports JVM fault injection in the container and the front-end switching between Chinese and English, and fixes many bugs

Enhancements

• Support jvm inject in container java process in chaosmetad. #78
• The frontend supports Chinese-English switching. #77 #60

Bug Fixes

• Fix the experimental arrangement serial and parallel execution, and the fault of each row is executed sequentially #70
• Fixed the issue where JVM fault injection cannot be performed on processes within the container #78
• Fix experimental attack scope: label configuration #69
• Fix some experimental configuration parameters #76
• Fix the problem of not supporting bool type parameters #73
• Fix some display bugs on the frontend #68

v0.5.1

This patch mainly enables chaosmetad to support the containerd container runtime, and enables ChaosMeta to operate in the k8s cluster of the containerd container runtime

Enhancements

• Chaosmetad support "containerd" container runtime. #59
• ChaosMeta as a whole can operate in the k8s cluster in the containerd runtime.

Bug Fixes

• Fix when deploying multiple operator components, webhook certificate verification fails. #74

v0.5.0

This version mainly released platform interface components (chaosmeta-platform), measurement components (chaosmeta-measure-operator) and flow injection components (chaosmeta-flow-operator).

For additional information, please refer to the changelog provided below.

Features

The following new features are supported:

Features of the platform interface

• Space management: Isolate data according to organization or activity to ensure data security and privacy.
• User rights management: Provide access rights control for different roles, which can effectively manage the use of chaos engineering experiments.
• Arranging experiments: Through drag-and-drop visual operations, the experiment arrangement is more friendly and flexible, and the work efficiency of users is improved. The current version of the interface only supports fault injection type nodes.
• Experimental results: Provide the traceability function of the experimental execution details, allowing users to know the execution status and results of the experiment at any time, which is convenient for users to conduct data analysis and decision-making.

Features of the measurement component

Currently includes 4 measurement capabilities:

• monitor: It is expected to judge the value of the monitoring item, such as whether the cpu usage monitoring value of a certain machine is greater than 90%, and prometheus is supported by default
• pod: predictive judgment on pod-related data, such as whether the number of pod instances of an application is greater than 3
• http: It is expected to judge the http request, for example, when the specified http request is made, whether the returned status code is 200
• tcp: To judge the expectations of tcp requests, such as testing whether port 8080 of a server can communicate

Features of the flow injection component

• HTTP: Inject HTTP request traffic

Bug Fixes

• Fix recovery processing logic when there is no attack target. #33

Others

• Deployment Tool: Implemented a unified and easy-to-use deployment tool. deployment documentation

v0.1.1

This patch release has some fixes for JVM experiment, remote injection. Added support for domestic docker image registry

Major Bug Fixes

• Fix the ClASSPATH dependency problem of JVM experiment #22
• Fix the underscore self-adaptation problem of multi-word args in Remote Injection
