修改节点分片数

# 临时增加分片数（重启es会设置时效）
PUT /_cluster/settings
{
  "transient": {
    "cluster": {
      "max_shards_per_node":900000
    }
  }
}

# 永久增加分片数（推荐）
PUT /_cluster/settings
{
  "persistent": {
    "cluster": {
      "max_shards_per_node":900000
    }
  }
}

删除镜像

docker rmi $(docker images | grep -E 'harbor.xxx.com/(qa|dev|prod)/' | awk -v OFS=":" '{print $1,$2}')

删除k8s中Evicted状态的pod

kubectl get po -A | grep 'Evicted' | awk 'NR>0 {print "kubectl delete po -n " $1,$2}' | bash

查看docker space

# overlay2无thin pool，devicemapper有thin pool。
docker info | grep Space

查看镜像和容器的空间

docker system df -v 或 docker system df -v | grep GB

方法一

test.py内容
mm="%s,%s,%s"%("aabbcc1",333,"cccc")
print(mm)

def retobj2 = "/usr/bin/python /data/script/test.py".execute().text.readLines()
retobj2.each{println it}

def retobj2 = "/usr/bin/python /tmp/11.py".execute().text.readLines()
return retobj2

方法二

test.py内容
jj = json.dumps({"name":"fulei.sssyang","age":"18"})
print(jj)

def respText = "/usr/local/python3/bin/python3 /data/script/py/test.py".execute().text
def slurper = new groovy.json.JsonSlurper() 
def branchs = slurper.parseText(respText) //parseText将json字符串转换为Map对象；JsonOutput类用于将Groovy对象转换为JSON字符串

方法三

python返回\n换行的字符串

"".execute().text.readLines()

方法4）
def html = "http://xxxxxx".toURL().text
def list = html.readLines()
