批量导出deploy、svc、ingress等信息

DEPLOY=`/usr/local/bin/kubectl get deployment -n zisefeizhu | awk '{print $1}'|grep -E "service|server" ` 
SVC=`/usr/local/bin/kubectl get svc -n zisefeizhu | awk '{$1=""; print $1}'`
INGRESS=`/usr/local/bin/kubectl get ingress -n zisefeizhu | awk '{$1=""; print $1}'`

pwd

mkdir -p $PWD/zisefeizhu/deploy
mkdir -p $PWD/zisefeizhu/svc
mkdir -p $PWD/zisefeizhu/ingress

for deploy in $DEPLOY
do
  /usr/local/bin/kubectl get deployment $deploy -n zisefeizhu -o yaml  > $PWD/zisefeizhu/deploy/"${deploy}".yaml;  
done


for svc  in $SVC
do
  /usr/local/bin/kubectl get svc $svc -n zisefeizhu -o yaml  > $PWD/zisefeizhu/svc/"${svc}".yaml;    
done


for ingress  in $INGRESS
do
  /usr/local/bin/kubectl get ingress $ingress -n zisefeizhu -o yaml  > $PWD/zisefeizhu/ingress/"${ingress}".yaml;             
done

删除一些附加字段

for object in $(find . -name '*.yaml')
do
  objectName=$object
  /usr/local/bin/yq eval 'del(.metadata.annotations)'  $object > ${object}.1
  object=${object}.1
  /usr/local/bin/yq eval 'del(.metadata.creationTimestamp)' $object > ${object}.1
  object=${object}.1
  /usr/local/bin/yq eval 'del(.metadata.generation)' $object > ${object}.1
  object=${object}.1
  /usr/local/bin/yq eval 'del(.metadata.resourceVersion)' $object > ${object}.1
  object=${object}.1
  /usr/local/bin/yq eval 'del(.metadata.selfLink)' $object > ${object}.1
  object=${object}.1
  /usr/local/bin/yq eval 'del(.metadata.uid)' $object > ${object}.1
  object=${object}.1
  /usr/local/bin/yq eval 'del(.status)' $object > $objectName
  #sed -i '' 's/namespace: zisefeizhu/namespace: stage-zisefizhu/g' $objectName
  rm -rf *.1
