Python Script to create new JIRA tickets using JIRA API


Python Script with below JIRA operations

  • Fetch JIRA ticket details using JIRA API.
  • Create JIRA ticket using JIRA API

Information to collect before using script.
  • Get your organization JIRA URL handy with you.
    • Can be retrieved from any JIRA ticket URL, respective URL has FQDN that's the JIRA URL dedicated for your organization.
  • Know your JIRA project/space name.
    • Login to any of your JIRA tickets.
    • From top navigation panel, select projects and check the name associated with the project, project name will be single word without any space.
  • Know JIRA field/mandatory fields within your ticket, before you create a ticket via API.
    • Will know how to fetch details about it from our python script, get_jita_details method can be used to get details for field

Script has one class and two methods, will know how and when to use one by one.
  • JiraHandler ( Class )
  • get_jira_details ( Method ) - Can be used to fetch JIRA ticket details.
  • create_jira_cr_ticket( Method ) - Can be used to create new JIRA ticket. 
Note : 
  • For simplicity, i have used basic authentication method to authenticate to JIRA servers, although for some sort of security instead of using plain text password, have encoded it using base64 authentication.
  • You need to ready with the Payload data json file, before you go ahead and create a new JIRA ticket, this file can be of any name but please content is in JSON format.


import requests
import json
import base64
from requests.auth import HTTPBasicAuth

# Inorder to encrypt/decrypt your credentials using base64 module as below.
# To encode --> base64.b64encode(bytes("random", "utf-8"))
# To decode --> base64.b64decode("cmFuZG9t").decode("utf-8")

class JiraHandler:
    def __init__(self, username):
        print('Loading Instnace variables...')
        self.username = username
        self.securestring = base64.b64decode("replaceItwithYourCredential").decode("utf-8")
        self.url = ""

    def get_jira_details(self,jira_ticket):

        try :
            auth = HTTPBasicAuth(self.username, self.securestring)
            get_details_url = self.url + jira_ticket

            headers = {
               "Accept": "application/json"
            print("retrieveing", jira_ticket, "details...")
            response = requests.request(
            print(json.dumps(json.loads(response.text), sort_keys=True, indent=4, separators=(",", ": ")))
        except Exception as e:
            return e

    def create_jira_cr_ticket(self, filename):
        get_details_url = self.url

        auth = HTTPBasicAuth(self.username, self.securestring)

        headers = {
           "Accept": "application/json",
           "Content-Type": "application/json"
            with open(filename, "r") as re_read_file:
                payload =
                print("Creating new JIRA...")
                response = requests.request(
                print(json.dumps(json.loads(response.text), sort_keys=True, indent=4, separators=(",", ": ")))
        except Exception as filenotfound:
            print("Can't load file..", filenotfound)


How to use it, 
  • Load Instance variable by calling class and provide your JIRA username as an input.
# Initiate Class and load instance variable.
d = JiraHandler("your_JIRA_Username")
  • Call method get_jira_details and add JIRA ticket as method input, for example if we want to get details about a specific JIRA ticket CKPROJ-6162, we must call the method as described below.
# Call below method to get JIRA ticket details.
  • Before calling method create_jira_cr_ticket, dump json content within a json file, for instance i have created a file named payload_data.json and it looks somehow like below.
    • Thinking how to find it, use method get_jira_details, it will give you an idea for the field used within your project's jira ticket.
        "fields": {
              "key": "CKPROJ"
           "summary": "My Dummy Ticket created by REST API",
           "description": "Dummy CR for REST API Test",
           "confluence": "Dummy Confluence Page Link",
           "verification_steps": "Verification Plan",
           "issuetype": {
              "name": "Change Request"
Once you are ready with the payload data, save it within a JSON file and call method providing payload_data.json file as an input to it, as an output script will return the JIRA ticket details.
# Call below method to create new JIRA ticket

Hope this script can have help in any sort, for any help comment please.

How to export and import Jenkins job.

If you have multiple jenkins instances, there might be a requirement to export an existing jenkins job, that could be further imported into the newer jenkins instance.

We will learn how to do the export/import of jenkins job using jenkins cli.

How to Export existing Jenkins job.

  • Jenkins Home Page 
  • Manage Jenkins
  • Jenkins CLI.
  • Download  jenkins-cli.jar

  • Click on Jenkins CLI.

Once file "jenkins-cli.jar" file has been downloaded, we are ready to export our Jenkins job, lets do it.
Open your terminal and run the below commands.

Authenticate and List down your jobs to identify the one, which one you want to export, replace "your-jenkins-server-url:your_server_port" from your source jenkins server's url and port.

cyberkeeda@jenkins-master:~$ java -jar jenkins-cli.jar -s "http://your-jenkins-server-url:your_server_port" -auth UserName:Password  list-jobs

docker ps

Now, from above enlisted jobs i want to export the one named as "djpass-docker-app".
Run the below command and replace the highlighted one by yours.

cyberkeeda@jenkins-master:~$  java -jar jenkins-cli.jar -s "http://your-jenkins-server-url:your_server_port" -auth UserName:Password get-job djpass-docker-app > djpass-docker-app.xml

We have successfully exported our jenkins job named as "djpass-docker-app" as an xml file named as "djpass-docker-app.xml"

How to import Jenkins job to different Jenkins server.

  • Go to your new jenkins server dashboard, where you want to import.
  • Follow the same above steps to download the jenkins-cli.jar file.
  • Ensure you are ready with "jenkins-cli.jar" and your exported jenkins job XML file with you.
Now run the below command to import your jenkins job xml file to new jenkins server.
Note : Replace the highlighted one by yours.

cyberkeeda@jenkins-slave:~$  java -jar jenkins-cli.jar -s "http://your-Newjenkins-server-url:your_server_port" -auth UserName:Password create-job new-djpass-docker-app < djpass-docker-app.xml

Hoah !!! Thats it, check your dashboard to verify the same.

AWK equivalent in Windows CMD

Missing AWK on Windows ?  for /f  may help you.
Lets see how can we implement the same.


C:\Users\Cyberkeeda>netsh interface show interface

Admin State    State          Type             Interface Name
Enabled        Connected      Dedicated        Wi-Fi
Enabled        Connected      Dedicated        VMware Network Adapter VMnet1
Enabled        Connected      Dedicated        VMware Network Adapter VMnet8
Enabled        Disconnected   Dedicated        Ethernet

Lets assume we have saved the same within a file in linux names as file.txt

Within Linux, to gather the State of interfaces, we use the below command.

cat file.txt| awk '{print $2}'


In Windows, it can be accomplished with FOR /F

C:\Users\cyberkeeda>for /f "tokens=2" %a in ('netsh interface show interface') do @echo %a


Now, if wish to add two values .

cat file.txt| awk '{print $1 " " $2}'

Admin State
Enabled Connected
Enabled Connected
Enabled Connected
Enabled Disconnected

Same can be accomplished within Windows as

C:\Users\cyberkeeda>for /f "tokens=1,2" %a in ('netsh interface show interface') do @echo %a %b
Admin State
Enabled Connected
Enabled Connected
Enabled Connected
Enabled Disconnected

In case, if you want to additional string along with the variable.

C:\Users\cyberkeeda>for /f "tokens=1,2" %a in ('netsh interface show interface') do @echo Boot Stats= %a Ethernet stat= %b

Now in case, if you want to use further filter within it, below one liner can help you.

C:\Users\cyberkeeda>netsh interface show interface | for /f "tokens=2" %a in ('findstr Wi-Fi') do @echo %a
