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。

    # Application archives to be migrated into the target container.
    archives:

    targetApplicationServer:
      profile: Liberty
      version: 23.0.0.4
      edition: Base
    targetContainer:
      # The target container base image name.

      # 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
