Yaml 你能帮我准备脚本复制源代码行并用nexus:1845替换quay.io吗

我有以下500多行：

source: quay.io/redhat-developer/openshift-jenkins-image-builder
source: registry.redhat.io/ocp-tools-4-tech-preview/jenkins-operator-bundle
source: registry.redhat.io/rhel8/skopeo

输出应该是这样的：（源是重复的，而不是quay.io应该是nexus:1855）

你能帮我准备脚本吗？这不是代码编写服务。到目前为止你都试了些什么。显示您的代码，并就您无法解决的问题询问特定问题。我编辑了我的问题如果这是您的代码-为什么使用python标记？这里没有python代码。对，删除了python标记
