自定义 WebSphere 工作负载的迁移计划
准备工作
本文档假设您已经创建迁移并已有迁移计划文件。
修改迁移计划
复制并分析文件系统后,您可以在指定输出路径 ANALYSIS_OUTPUT_PATH/config.yaml
中创建的新目录中找到迁移计划。
根据需要修改迁移计划,然后保存更改。
查看迁移计划的详细信息和指导性注释以根据需要添加信息。
具体而言,请考虑针对以下部分的修改。
迁移计划结构
WebSphere 工作负载的迁移计划具有以下结构,您可以按照以下部分中的说明进行自定义。

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
排除应用
如需从迁移中排除应用,请从 applications
列表中移除相关应用。
applications:
# Exclude app1.war:
# - path: app1.war
# ...
- path: app2.war
控制应用文件
如需控制在迁移中包含或排除哪些应用文件,请更新 configurations
和 resources
字段。
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
自定义目标 Java 运行时
如需自定义应用的目标 Java 运行时,请更新 targetJavaRuntime
字段。
applications:
- path: app.war
targetJavaRuntime:
se: SE
ee: EE
vendor: VENDOR
替换以下内容:
- 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 供应商。格式:[IBM Corporation|Oracle Corporation]。
自定义目标应用服务器
如需自定义应用的目标应用服务器,请更新 targetApplicationServer
字段。
applications:
- path: app.war
targetApplicationServer:
profile: PROFILE
version: VERSION
edition: EDITION
替换以下内容:
- PROFILE:WebSphere 配置文件。格式:[Liberty|Traditional]。
- TARGET_VERSION:WebSphere 版本号 (version)。
- TARGET_EDITION:WebSphere 版本 (edition)。格式:[Base|Core|Open|ND]。
自定义目标容器
如需自定义要用于应用的目标容器,请更新 targetContainer
字段。
applications:
- path: app.war
targetContainer:
baseImage: BASE_IMAGE
home: HOME
server: SERVER
user: USER
group: GROUP
自定义 Kubernetes Secret
默认情况下,keystores
字段下列出的文件会迁移到 Kubernetes Secret。如需按原样迁移这些文件,您可以停用此功能。
applications:
- path: app.war
resources:
keystores:
- key.p12
targetContainer:
# Do not migrate keystores to Kubernetes secrets:
enableSecrets: false
自定义 Kubernetes 端口
如需控制 Kubernetes Pod 和 Service 开放哪些端口,请更新 ports
字段。
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
