Running one linux command and saving the ouput of the command as list and then reding the list item one by one.
stage('NAMESPACE Availability') {
node ('master'){
withEnv(["KUBECONFIG=${JENKINS_HOME}/.kube/config"]){
NS_list = sh (
script: '''kubectl get ns | awk '{print \$1}' | awk '{\$1=\$1; print "[\\x27" $0 "\\x27]"}' FS='\n' OFS="','" RS='' ''',
returnStdout: true
).trim()
echo "${NS_list}"
NS(NS_list)
}
}
}
def NS(list) {
for (i in list) {
echo "${i}"
if ( i == "${NAME_SPACE}" ) {
sh "kubectl delete all --all -n '${NAME_SPACE}' && kubectl delete '${NAME_SPACE}' "
break;
}
}
}
Rather then reading as Item its reading as character , Lets say if command output is ['NAME','b2','b6','b7','cert-manager','default'] its reading as below output.
[Pipeline] echo
[
[Pipeline] echo

[Pipeline] echo

You haven't declared NS_list, that will store everything as a string. Add def NS_list = [] at the beginning of your pipeline
I solved my problem as per below changes. Rather then using for(loop).. i used ".contains"
stage('NAMESPACE Availability') {
node ('master'){
withEnv(["KUBECONFIG=${JENKINS_HOME}/.kube/config"]){
NS_list = sh (
script: '''kubectl get ns | awk '{print \$1}' ''',
returnStdout: true
).trim()
def lst = "${NS_list}";
NS = (lst.contains( "${NAME_SPACE}" ));
echo "${NS}"
if ( NS == true ) {
sh "kubectl delete all --all -n ${NAME_SPACE} "
}
else {
sh "kubectl create ns ${NAME_SPACE}"
}
}
