OpenShift Security (8) - 安装并运行 DevSecOps 应用

《OpenShift 4.x HOL教程汇总》
本文在 OpenShift 4.9 和 RHACS 3.67.1 环境中进行验证。

DevSecOps Pipeline Demo 是使用以下环境的 CI/CD Pipeline，它使用的是基于 Tekton 驱动的 OpenShift Pipeline 组件驱动运行。而 RHACS 负责对镜像进行安全扫描。

• RHACS
• SonarQube
• Nexus
• JUnit
• Gogs
• Git Webhook
• Gatling
• Zap Proxy
  

安装 DevSecOps Pipeline 演示环境

1. 下载 devsecops demo 应用资源

$ pip3 install openshift pyyaml kubernetes --user
$ ansible-galaxy collection install kubernetes.core
$ ansible-galaxy collection install community.kubernetes
$ ansible-galaxy collection install cloud.common
$ git clone https://github.com/rcarrata/devsecops-demo.git
$ cd devsecops-demo

2. 设置 RHACS 的访问密码

$ ACS_PASSWORD_BASE64=$(oc -n stackrox get secret central-htpasswd -o jsonpath={
     
     .data.htpasswd})
$ cat > bootstrap/roles/ocp4-install-acs/templates/acs-password.yml.j2 << EOF
kind: Secret
apiVersion: v1
metadata:
  name: acs-password
  namespace: stackrox
data:
  password: ${ACS_PASSWORD_BASE64}
type: Opaque
EOF

3. 如果用的是 OpenShift 4.9，则需要修改 bootstrap/roles/ocp4-install-gitops/tasks/gitops.yaml 文件的内容，将两处的 “apiextensions.k8s.io/v1beta1” 修改为 “apiextensions.k8s.io/v1”。
4. 安装 devsecops demo 应用资源

$ ./install.sh
。。。

localhost                  : ok=65   changed=9    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0

4. 查看 DevSecOps 相关环境

$ ./status.sh

## ACS/Stackrox Server - Username/Password: admin/stackrox ##

运行 DevSecOps Pipeline

用安全策略控制 CI/CD 的 Security Gate

1. 执行命令，运行 DevSecOps Pipeline。

$ ./demo.sh start
 
# INFO: ## Executing Dev Pipeline... ##
pipelinerun.tekton.dev/petclinic-build-devc9ptn created
 
# INFO: Check the pipeline in:
https://console-openshift-console.apps.cluster-mcz5p.mcz5p.sandbox1644.opentlc.com/pipelines/ns/cicd/pipeline-runs

2. 查看 Pipeline 运行状态，此时管道运行状态是“失败”。然后进入下图的“日志”。
   
3. 可以看到 Pipeline 停在 “image-check”，并提示以下错误：

ERROR: failed policies found: 1 policies violated that are failing the check
ERROR: Policy "Fixable Severity at least Important" - Possible remediation: "Use your package manager to update to a fixed version in future builds or speak with your security team to mitigate the vulnerabilities."

4. 在 RHACS 中进入 System Policies，然后查找到 “Fixable Severity at least Important”。选择查找到的策略，然后在右侧窗口点击“Edit”，在下图的步骤中确保 BUILD 和 DEPLOY 都是 OFF 状态，最后点击 SAVE 即可。
   
5. 重新运行 Pipeline，确认这次可以成功运行。
