為 WebSphere 工作負載自訂遷移計畫

事前準備

本文件假設您已建立遷移作業，並擁有遷移計畫檔案。

編輯遷移計畫

複製及分析檔案系統後，您可以在指定輸出路徑 ANALYSIS_OUTPUT_PATH/config.yaml 中建立的新目錄中找到遷移計畫。

視需要編輯遷移計畫並儲存變更。

查看遷移計畫詳細資料和指引性註解，視需要新增資訊。

具體來說，請考慮針對下列部分進行編輯：

遷移計畫結構

WebSphere 工作負載的遷移計畫具有下列結構，您可以按照下列各節的說明進行自訂。

# List of discovered WebSphere application servers and how to migrate their # hosted applications to containers. webSphereApplicationServers: # The application server installation path. - home: /opt/ibm/wlp   applicationServerInfo:     name: WebSphere Application Server     profile: Liberty     version: 23.0.0.4     edition: Base     # List of Java installations available to the application server.     javaDevelopmentKits:     - home: /opt/ibm/java       vendor: IBM Corporation       version:         jdk: java version 1.8.0_361         jre: Java(TM) SE Runtime Environment         jvm: IBM J9 VM   # List of hosted applications and how to migrate them to containers.   applications:   - path: /opt/ibm/wlp/usr/servers/defaultServer/apps/app.war     # Application archives to be migrated into the target container.     archives:     - /opt/ibm/wlp/usr/servers/defaultServer/apps/app.war     # Application configuration files to be migrated into the target container.     configurations:       serverXML: /opt/ibm/wlp/usr/servers/defaultServer/server.xml       serverEnv:       - /opt/ibm/wlp/usr/servers/defaultServer/server.env       bootstrapProperties:       - /opt/ibm/wlp/usr/servers/defaultServer/bootstrap.properties       variableProperties:       - /opt/ibm/wlp/usr/servers/defaultServer/variables/variable.properties       jvmOptions:       - /opt/ibm/wlp/usr/servers/defaultServer/jvm.options     # Application resource files to be migrated into the target container.     resources:       locations:       - /opt/ibm/wlp/usr/servers/defaultServer/resources/ports.xml       libraries:       - /opt/ibm/wlp/usr/servers/defaultServer/resources/postgresql.jar       keystores:       - /opt/ibm/wlp/output/defaultServer/resources/security/key.p12       sharedResources:         - /opt/ibm/wlp/usr/shared/resources/jdbc.jar       additionalResources:       - /opt/ibm/wlp/output/defaultServer/resources/mongodb.jar     javaRuntime:       se: SE8       ee: EE7       vendor: IBM Corporation     targetJavaRuntime:       se: SE8       ee: EE7       vendor: IBM Corporation     targetApplicationServer:       profile: Liberty       version: 23.0.0.4       edition: Base     targetContainer:       # The target container base image name.       baseImage: ibmcom/websphere-liberty:full-java8-ibmjava-ubi       # The application server installation path within the target container       # base image.       home: /opt/ibm/wlp       # The application server default server name.       server: defaultServer       # The UID or name of the user configured within the target container       # base image. Defaults to 1001 for Liberty profile.       user: "1001"       # The GID or name of the group configured within the target container       # base image. Defaults to 0 for Liberty profile.       group: "0"       # Application ports to be exposed in Kubernetes artifacts.       ports:       - name: http-tcp-9080         port: 9080         protocol: TCP       - name: https-tcp-9443         port: 9443         protocol: TCP       # Specify whether discovered keystores are automatically converted to       # Kubernetes secrets. Defaults to true.       enableSecrets: true

排除應用程式

如要將應用程式排除在遷移作業範圍之外，請將其從 applications 清單中移除。

  applications:   # Exclude app1.war:   # - path: app1.war   #  ...   - path: app2.war

控制應用程式檔案

如要控管要納入或排除哪些應用程式檔案，請更新 configurations 和 resources 欄位。

  applications:   - path: app.war     resources:       keystores:       # Exclude key1.p12:       # - key1.p12       # Include key2.p12:       - key2.p12       additionalResources:       # Exclude resource1.xml:       # - resource1.xml       # Include resource2.xml:       - resource2.xml

自訂目標 Java 執行階段

如要為應用程式自訂目標 Java 執行階段，請更新 targetJavaRuntime 欄位。

  applications:   - path: app.war     targetJavaRuntime:       se: SE       ee: EE       vendor: VENDOR

更改下列內容：

  • SE：Java SE 版本。格式：[SE8|SE11|SE17]。
  • EE：Java EE 或 Jakarta EE 版本。格式：[EE7|EE8|EE9|EE10]。
  • VENDOR：Java 供應商。格式：[IBM Corporation|Oracle Corporation]。

自訂目標應用程式伺服器

如要為應用程式自訂目標應用程式伺服器，請更新 targetApplicationServer 欄位。

  applications:   - path: app.war     targetApplicationServer:       profile: PROFILE       version: VERSION       edition: EDITION

更改下列內容：

  • PROFILE：WebSphere 設定檔。格式：[Liberty|Traditional]。
  • TARGET_VERSION：WebSphere 版本。
  • TARGET_EDITION：WebSphere 版本。格式：[Base|Core|Open|ND]。

自訂目標容器

如要自訂應用程式要使用的目標容器，請更新 targetContainer 欄位。

  applications:   - path: app.war     targetContainer:       baseImage: BASE_IMAGE       home: HOME       server: SERVER       user: USER       group: GROUP

自訂 Kubernetes 密鑰

根據預設，keystores 欄位下列出的檔案會遷移至 Kubernetes 機密資料。如要原封不動地遷移這些檔案，可以停用這項功能。

  applications:   - path: app.war     resources:       keystores:       - key.p12     targetContainer:       # Do not migrate keystores to Kubernetes secrets:       enableSecrets: false

自訂 Kubernetes 連接埠

如要控管 Kubernetes Pod 和服務公開的通訊埠，請更新 ports 欄位。

  applications:   - path: app.war     targetContainer:       ports:       # Exclude http-tcp-9080:       # - name: http-tcp-9080       #   port: 9080       #   protocol: TCP       # Include https-tcp-9443:       - name: https-tcp-9443         port: 9443         protocol: TCP
