Chaosblade-box: An chaos engineering platform with rich scenes

Introduction

Chaosblade-box is an chaos engineering platform with rich scenes, the scenes currently included are:

• chaosblade-exec-os: Implementation of basic resource experimental scenarios.
• chaosblade-exec-docker: Docker container experimental scenario implementation, standardized by calling the Docker API.
• chaosblade-operator: Kubernetes platform experimental scenario is implemented, chaos experiments are defined by Kubernetes standard CRD method, it is very convenient to use Kubernetes resource operation method To create, update, and delete experimental scenarios, including using kubectl, client-go, etc., and also using the chaosblade cli tool described above.
• chaosblade-exec-jvm: Java application experimental scenario implementation, using Java Agent technology to mount dynamically, without any access, zero-cost use It also supports uninstallation and completely recycles various resources created by the Agent.
• chaosblade-exec-cplus: C ++ application experimental scenario implementation, using GDB technology to implement method and code line level experimental scenario injection.
• limus-chaos-generic: An toolset to do cloud-native chaos engineering

Compile

Go to the project root directory which you cloned and execute compile:

mvn clean package -Dmaven.test.skip=true

If you compile the chaosblade-box image, you can do:

make build_image

clean compilation:

mvn clean

helm package:

helm package deploy/chaosblade-box

Pre Run Application For Host

1. If don't have ansible installed, you need install ansible

# Check if there is already installed
ansible --version

# install ansible, eg: Fedora || RedHat 
yum install ansible -y

2. If don't have expect installed, you need install expect, put sshKey.sh and chaosblade-box-1.0.4.jar in a directory

# Check if there is already installed
expect -v

# install expect, eg: Fedora || RedHat 
yum install expect -y

3. Generate public key

# Check if there is already a key, if there is, delete the previous backup
ls ~/.ssh
rm -rf ~/.ssh/*

# generate public key
ssh-keygen -t rsa

Run Application

If you already have MySQL installed, you need to create a schema named chaosblade, if you don't have MySQL installed, you can run it via Docker, run method is as follows:

docker run -d -it -p 3306:3306 \
            -e MYSQL_DATABASE=chaosblade \
            -e MYSQL_ROOT_PASSWORD=[DATASOURCE_PASSWORD] \
            --name mysql-5.6 mysql:5.6 \
            --character-set-server=utf8mb4 \
            --collation-server=utf8mb4_unicode_ci \
            --default-time_zone='+8:00' \
            --lower_case_table_names=1

Notes: You must replace the follow parameters: DATASOURCE_HOST, DATASOURCE_USERNAME, DATASOURCE_PASSWORD, BOX-HOST(localHostIP:port, eg:...:7001)

Then run the application, run method is as follows:

nohup java -Duser.timezone=Asia/Shanghai -jar chaosblade-box-1.0.0.jar --spring.datasource.url="jdbc:mysql://DATASOURCE_HOST:3306/chaosblade?characterEncoding=utf8&useSSL=false" --spring.datasource.username=DATASOURCE_USERNAME --spring.datasource.password=DATASOURCE_PASSWORD --chaos.server.domain=BOX-HOST> chaosblade-box.log 2>&1 &

You can use a browser to access the http://127.0.0.1:7001 website to use the platform.

If you're deployed on kubernetes, the usage method is as follows:

helm install chaosblade-box chaosblade-box-1.0.0.tgz --namespace chaosblade --set spring.datasource.password=DATASOURCE_PASSWORD

You can get BOX-HOST by services. You can use a browser to access the http://10.10.10.03:7001 website to use the platform.

➜  shell kubectl get services -n chaosblade

We welcome every contribution, even if it is just punctuation. See details of CONTRIBUTING

Business Registration

The original intention of our open source project is to lower the threshold for chaos engineering to be implemented in enterprises, so we highly value the use of the project in enterprises. Welcome everyone here ISSUE. After registration, you will be invited to join the corporate mail group to discuss the problems encountered by Chaos Engineering in the landing of the company and share the landing experience.
