第 3 章 在受限环境中的 Openshift 上安装 Fuse
要在非限制的环境中的 OpenShift 上安装 Fuse，您可以从 registry.redhat.io 中拉取镜像流和模板。在没有或有限的互联网访问的生产环境中，无法实现。本节介绍如何在受限环境中的 OpenShift 上安装 Fuse。
注意
IBM Power Systems、IBM Z 和 LinuxONE 目前不支持在受限环境中安装。
先决条件
- 您已安装并配置了 OpenShift 服务器，以便它可以在受限环境中运行。
3.1. 设置内部 Docker registry
本节介绍如何设置可用于推送或拉取镜像的内部 docker registry。您必须配置可拉取或推送镜像的内部 docker registry。
步骤
安装内部 ROOT CA。
cd /etc/pki/ca-trust/source/anchors sudo curl -O https://password.corp.redhat.com/RH-IT-Root-CA.crt sudo update-ca-trust extract sudo update-ca-trust update
此证书允许系统向 registry 验证其自身。
登录
registry.redhat.io。docker login -u USERNAME -p PASSWORD registry.redhat.io
从
registry.redhat.io拉取 OpenShift 镜像上的 Fuse。docker pull registry.redhat.io/fuse7/fuse-java-openshift-rhel8:1.12 docker pull registry.redhat.io/fuse7/fuse-java-openshift-jdk11-rhel8:1.12 docker pull registry.redhat.io/fuse7/fuse-karaf-openshift-rhel8:1.12 docker pull registry.redhat.io/fuse7/fuse-console-rhel8:1.12 docker pull registry.redhat.io/fuse7/fuse-apicurito-rhel8:1.12 docker pull registry.redhat.io/fuse7/fuse-apicurito-generator-rhel8:1.12
标记拉取的镜像流。
docker tag registry.redhat.io/fuse7/fuse-java-openshift-rhel8:1.12 docker-registry.upshift.redhat.com/fuse7/fuse-java-openshift-rhel8:1.12 docker tag registry.redhat.io/fuse7/fuse-java-openshift-jdk11-rhel8:1.12 docker-registry.upshift.redhat.com/fuse7/fuse-java-openshift-jdk11-rhel8:1.12 docker tag registry.redhat.io/fuse7/fuse-karaf-openshift-rhel8:1.12 docker-registry.upshift.redhat.com/fuse-karaf-openshift-rhel8:1.12 docker tag registry.redhat.io/fuse7/fuse-console-rhel8:1.12 docker-registry.upshift.redhat.com/fuse7-fuse-console-rhel8:1.12 docker tag registry.redhat.io/fuse7/fuse-apicurito-rhel8:1.12 docker-registry.upshift.redhat.com/fuse7-fuse-apicurito-rhel8:1.12 docker tag registry.redhat.io/fuse7/fuse-apicurito-generator-rhel8:1.12 docker-registry.upshift.redhat.com/fuse7-fuse-apicurito-generator-rhel8:1.12
将标记的镜像流推送到内部 docker registry。
docker push docker-registry.upshift.redhat.com/fuse7/fuse-java-openshift-rhel8:1.12 docker push docker-registry.upshift.redhat.com/fuse7/fuse-java-openshift-jdk11-rhel8:1.12 docker push docker-registry.upshift.redhat.com/fuse-karaf-openshift-rhel8:1.12 docker push docker-registry.upshift.redhat.com/fuse7-fuse-console-rhel8:1.12 docker push docker-registry.upshift.redhat.com/fuse7-fuse-apicurito-rhel8:1.12 docker push docker-registry.upshift.redhat.com/fuse7-fuse-apicurito-generator-rhel8:1.12
