JIRA API not able to run on gunicron for flask app-CodePudding

I am trying to deploy my JiraAPI flask app on gunicorn in centos VM. i have used JIRA module for it. Here is my class

class Jira:
    #initilizing the class
    def __init__(self):
        # private variables
        self.logger = logging.getLogger('jiraUtil')
        self.__email = environ.get('email')
        self.__secret = environ.get('secret')
        self.logger.debug("Connecting to Jira API")
        jira_options = {
            'server':  environ.get('baseUrl'),
        }
        self.jira_con = JIRA(jira_options, basic_auth=(self.__email, self.__secret),max_retries=0)
        if not self.jira_con:
            self.logger.error("Error connecting to Jira")
            raise ValueError("Error connecting to Jia")

    def createIssue(self,issue_dict) -> dict:
        self.logger.info("inside jira ticket creation")
        new_issue_body = {}
        try:
            new_issue = self.jira_con.create_issue(fields=issue_dict)
            print('new_issue')
            new_issue_body['id'] = new_issue.id
            new_issue_body['key'] = new_issue.key
            new_issue_body['self'] = new_issue.self
            return new_issue_body
        except Exception as e:
            self.logger.error("Error creating SSD ticket: ",e)
            return new_issue_body

In my app.py

@app.route('/api/createTicket/', methods=['POST'])
def createTicket():
    app.logger.info('Creating Issue Ticket')
    request_data = request.get_json()
    fields_dict = request_data.get('fields',None)
    if fields_dict == None :
        return jsonify({"result":"failure","status":"400", "message":"Bad Request"}),400 
    jiraObj = JiraUtil.Jira()
    newIssueKey = jiraObj.createIssue(fields_dict)
    if newIssueKey == None:
        return jsonify({"result":"failure","status":"503", "message":"service Unavailable"}),500
    return newIssueKey,200
if __name__ == '__main__':
   app.run()

When i am running the app using flask run -h 0.0.0.0 -p 5000it is working fine and I am able to connect with my local postman the logs got generated :

Please help

CodePudding user response：

The problem is that gunicorn is not able to read the environment variables that you have declared in the .env file.

So, just configure a service file app.service in /etc/systemd/system and add EnvironmentFile=/path_to_env_file under [service] and start the service.

For more info on configuring the env file in gunicorn service, you can see here.
