红帽全球峰会第 4 章 在 Red Hat Developer Hub 中配置 readOnlyRootFilesystem
Red Hat Developer Hub 部署由两个容器组成：一个 initContainer，用于安装 Dynamic Plugins，以及一个运行应用程序的后端容器。initContainer 默认启用 readOnlyRootFilesystem 选项。要在后端容器上启用这个选项，您必须有权通过 Helm 部署资源，或为 Operator 支持的部署创建或更新 CR。您可以使用以下方法在后端容器上手动配置 readOnlyRootFilesystem 选项：
- Red Hat Developer Hub Operator
- Red Hat Developer Hub Helm chart
4.1. 在 Red Hat Developer Hub Operator 部署中配置 readOnlyRootFilesystem 选项
当使用 Operator 部署 Developer Hub 时，您必须在 Backstage 自定义资源(CR)中为 部署 指定一个 补丁，它将 readOnlyRootFilesystem 选项应用到 Developer Hub 后端容器中的 securityContext 部分。
流程
在
BackstageCR 中，添加securityContext规格。例如：spec: deployment: patch: spec: template: spec: containers: - name: backstage-backend securityContext: readOnlyRootFilesystem: truespec: deployment: patch: spec: template: spec: containers: - name: backstage-backend1 securityContext: readOnlyRootFilesystem: trueCopy to Clipboard Copied! - 1
- Operator 默认配置中定义的主容器的名称。
