k8s去掉managedFields的简洁编排文件

下载yq，使用yq截取我们需要的编排文件
点击下载yq

下载yq后，拷贝到/usr/local/bin下，例如cp yq_linux_amd64 /usr/local/bin/yq && chmod +x /usr/local/bin/yq

将下面内容添加到～/.bashrc

neat () {
  yq eval 'del(
    .metadata.managedFields,
    .metadata.resourceVersion,
    .metadata.selfLink,
    .metadata.creationTimestamp,
    .metadata.ownerReferences,
    .metadata.uid,
    .spec.strategy,
    .spec.revisionHistoryLimit,
    .spec.template.spec.containers[].terminationMessagePath,
    .spec.template.spec.containers[].terminationMessagePolicy,
    .status)' -
}

neatv () {
  s=.spec.template.spec$1
  yq eval $s 
}

执行source ~/.bashrc
