Question

我想在修补任何部署配置时动态传递参数

oc patch dc / action-msa -p“ $（cat msa-patch.yml）” --param service_account = msa-service-account

  spec:
     template:
       spec:
       serviceAccountName: ${service_account}
       restartPolicy: "Always"

       initContainers:
         - name: vault-init
           image: ${init_container_image}
           imagePullPolicy: Always
       containers:
        - name: ${SERVICE_NAME}-java-service
          image: ${main_container_image}

在使用openshift oc修补时，是否有任何选项或方法可以动态传递service_account，init_container_image和service_name？

您需要此解决方案的模板层，例如Kustomize，HELM等。或者，您可以在部署yaml文件之前使用环境文件作为源，如下所示

您的 deployment.yaml 看起来像这样：

  spec:
     template:
       spec:
       serviceAccountName: {{service_account}}
       restartPolicy: "Always"

       initContainers:
         - name: vault-init
           image: {{init_container_image}}
           imagePullPolicy: Always
       containers:
        - name: {{SERVICE_NAME}}
          image: {{main_container_image}}

您的 env.file 看起来像这样：

service_account="some_account"
init_container_image="some_image"
SERVICE_NAME="service_name"

然后运行

oc patch dc/action-msa -p \
"$(source env.file && cat deployment.yml  | \
sed "s/{{service_account}}/service_account/g"| \
sed "s/{{init_container_image}}/init_container_image/g"| \
sed "s/{{SERVICE_NAME}}/SERVICE_NAME/g")" --param service_account=msa-service-account
