Question

有没有办法用cli删除以前的部署？

当我成功运行oc import-image $APPLICATION时，会出现一个带有RC的新部署，经过几次运行后，我点击了RC max，并且必须手动删除以前的部署。

是否有类似oc delete rc $APPLICATION-$(($DEPLOYMENT_NUMBER - 1))的脚本？

Answer 1

我最终使用以下代码创建（匆忙）解决方案。

# DEPLOYMENT_COUNT will be the number of deployments
DEPLOYMENT_COUNT=`oc get rc | wc -l` 
DEPLOYMENT_COUNT=$((DEPLOYMENT_COUNT - 1))
for ((i=1; i<$DEPLOYMENT_COUNT + 1; i++))
 do
    #CURR_POD_LINE=`oc get rc | tail -$i | head -n1`
    DEPLOYMENT_ID=`oc get rc | tail -$i | head -n1 | awk '{print $1}'`
    DESIRED_PODS_COUNT=`oc get rc | tail -$i | head -n1 | awk '{print $5}'`

    # IF number of desired pods is 0, then delete the deployment
    if [ $DESIRED_PODS_COUNT -eq 0 ]
      then
        #DELETE
        oc delete rc $DEPLOYMENT_ID
    fi
    echo $DEPLOYMENT_ID
    echo $DESIRED_PODS_COUNT
 done

随着时间的推移，您最终可能会遇到很多复制控制器，因此您需要清除它们。您可以使用oc delete rc <rc-num>甚至更好oc adm prune来执行此操作。结帐oc adm options和oc adm prune --help了解选项。

$ oc adm prune deployments --keep-complete=5 --namespace=myproject --confirm
