2.2. 在 OpenShift 4.x 服务器上安装 Fuse 镜像流和模板

流程

1. 启动 OpenShift 4 服务器。

2. 以管理员身份登录 OpenShift 服务器。

   oc login --user system:admin --token=my-token --server=https://my-cluster.example.com:6443

3. 验证您是否使用您为其创建 docker-registry secret 的项目。

   oc project openshift

4. 查看 Samples operator 的当前配置。

   oc get configs.samples.operator.openshift.io -n openshift-cluster-samples-operator -o yaml

5. 配置 Samples operator 以忽略添加的 fuse 模板和镜像流。

   oc edit configs.samples.operator.openshift.io -n openshift-cluster-samples-operator

6. 添加 Fuse imagestreams Skipped Imagestreams 部分，并将 Fuse 和 Spring Boot 2 模板添加到 Skipped Templates 部分。

     - s2i-fuse710-spring-boot-2-cxf-jaxws-xml

7. 在 OpenShift 镜像流上安装 Fuse：

   1. 将 BASEURL 变量设置为镜像流的位置：

      对于 Fuse 7.10.1

      BASEURL=https://raw.githubusercontent.com/jboss-fuse/application-templates/application-templates-2.1.0.fuse-sb2-7_10_1-00010-redhat-00001

      对于 Fuse 7.10.0

      BASEURL=https://raw.githubusercontent.com/jboss-fuse/application-templates/application-templates-2.1.0.fuse-sb2-7_10_0-00015-redhat-00001

   2. 运行安装镜像流的命令：

      oc create -n openshift -f ${BASEURL}/fis-image-streams.json

      注意

      如果显示错误，并显示消息 "Error from server (AlreadyExists): imagestreams.image.openshift.io <imagestreamname> already exists"，请使用以下命令将现有镜像流替换为最新的镜像流。

      oc replace --force -n openshift -f ${BASEURL}/fis-image-streams.json

8. 在 OpenShift 快速启动模板上安装 Fuse：

   for template in eap-camel-amq-template.json \
    eap-camel-cdi-template.json \
    eap-camel-cxf-jaxrs-template.json \
    eap-camel-cxf-jaxws-template.json \
    karaf-camel-amq-template.json \
    karaf-camel-log-template.json \
    karaf-camel-rest-sql-template.json \
    karaf-cxf-rest-template.json ;
    do
    oc create -n openshift -f \
    https://raw.githubusercontent.com/jboss-fuse/application-templates/application-templates-2.1.0.fuse-sb2-7_10_0-00015-redhat-00001/quickstarts/${template}
    done

9. 安装 Spring Boot 2 Quickstart 模板：

   for template in spring-boot-2-camel-amq-template.json \
    spring-boot-2-camel-config-template.json \
    spring-boot-2-camel-drools-template.json \
    spring-boot-2-camel-infinispan-template.json \
    spring-boot-2-camel-rest-3scale-template.json \
    spring-boot-2-camel-rest-sql-template.json \
    spring-boot-2-camel-template.json \
    spring-boot-2-camel-xa-template.json \
    spring-boot-2-camel-xml-template.json \
    spring-boot-2-cxf-jaxrs-template.json \
    spring-boot-2-cxf-jaxws-template.json \
    spring-boot-2-cxf-jaxrs-xml-template.json \
    spring-boot-2-cxf-jaxws-xml-template.json ;
    do oc create -n openshift -f \
    https://raw.githubusercontent.com/jboss-fuse/application-templates/application-templates-2.1.0.fuse-sb2-7_10_0-00015-redhat-00001/quickstarts/${template}
    done

10. （可选） 查看 OpenShift 模板上安装的 Fuse：

    oc get template -n openshift
