红帽全球峰会3.2. 获取镜像 registry 容器镜像列表
要使用镜像 registry，您必须知道哪些容器镜像引用由 MicroShift 的特定版本使用。这些引用在作为 microshift 文件中提供。
-release-info RPM 软件包一部分的 release-<arch>.json
注意
要在断开连接的环境中镜像 Operator Lifecycle Manager (OLM)，请添加 release-olm-$ARCH.json 中提供的引用，该引用包含在 microshift-olm RPM 中，并按照相同的流程操作。使用 oc-mirror 来镜像 Operator 目录和 Operator。
先决条件
- 已安装 jq。
流程
使用以下方法之一访问容器镜像引用列表：
如果在 MicroShift 主机上安装了软件包，请运行以下命令获取文件的位置：
rpm -ql microshift-release-info
$ rpm -ql microshift-release-infoCopy to Clipboard Copied! Toggle word wrap Toggle overflow 输出示例
/usr/share/microshift/release/release-x86_64.json
/usr/share/microshift/release/release-x86_64.jsonCopy to Clipboard Copied! Toggle word wrap Toggle overflow 如果 MicroShift 主机上没有安装该软件包，请运行以下命令在不安装 RPM 软件包的情况下下载并解包 RPM 软件包：
rpm2cpio microshift-release-info*.noarch.rpm | cpio -idmv
$ rpm2cpio microshift-release-info*.noarch.rpm | cpio -idmvCopy to Clipboard Copied! Toggle word wrap Toggle overflow 输出示例
/usr/share/microshift/release/release-x86_64.json
/usr/share/microshift/release/release-x86_64.jsonCopy to Clipboard Copied! Toggle word wrap Toggle overflow
运行以下命令，将容器镜像列表提取到
microshift-container-refs.txt文件中：RELEASE_FILE=/usr/share/microshift/release/release-$(uname -m).json
$ RELEASE_FILE=/usr/share/microshift/release/release-$(uname -m).jsonCopy to Clipboard Copied! Toggle word wrap Toggle overflow jq -r '.images | .[]' ${RELEASE_FILE} > microshift-container-refs.txt$ jq -r '.images | .[]' ${RELEASE_FILE} > microshift-container-refs.txtCopy to Clipboard Copied! Toggle word wrap Toggle overflow
注意
使用 MicroShift 容器镜像列表创建 microshift-container-refs.txt 文件后，您可以在运行镜像步骤前附加文件与其他特定于用户的镜像引用。
