Jenkins Microservice

This microservice is used to execute jenkins job on the specified jenkins server. It require jenkins user credentials such as login id and jenkins api-token with job details to fire the job.

Installation

Checkout Repository

git clone https://github.com/swiftops/jenkins-service.git

1. Deploy inside Docker

Pre-Requisite

  • Docker should be installed on your machine. Refer Install Docker documentation.
  • Jenkins server installed and running. Refer Install Jenkins documentation. Also make sure that atleast one job is created.
  • Specify Jenkins credentials in config.ini

Steps to start microservice

Once you are done with pre-requisite execute below command in the checkout directory to start Jenkins microservice.

docker build -t <image-name> .
docker run -p 8098:8098 --name <container_name> -d <image-name>

2. On Commit Auto-deploy on specific server

To autodeploy your docker container based service on server used below steps You need to configure Gitlab Runner to execute Gitlab CI/CD Pipeline. See Gitlab Config Change ip address in deploy.sh file with your IP on which autodeploy needs to be done. As soon as you configure runner auto deployment will start as you commited the code in repository. refer .gitlab-ci.yml file.

3. Deploy on local environment

Create Virtual Environment

Virtualenv is the easiest and recommended way to configure a custom Python environment for your services. To install virtualenv execute below command:

pip3 install virtualenv

You can check version for virtual environment version by typing below command:

virtualenv --version

Create a virtual environment for a project:

cd my_project_folder
virtualenv virtenv

virtualenv virtenv will create a folder in the current directory which will contain the Python executable files, and a copy of the pip library which you can use to install other packages. The name of the virtual environment (in this case, it was virtenv) can be anything; omitting the name will place the files in the current directory instead.

This creates a copy of Python in whichever directory you ran the command in, placing it in a folder named virtenv.

You can also use the Python interpreter of your choice (like python3.6).

virtualenv -p /usr/bin/python3.6 virtenv

To begin using the virtual environment, it needs to be activated:

source virtenv/bin/activate

The name of the current virtual environment will now appear on the left of the prompt (e.g. (virtenv)Your-Computer:your_project UserName$) to let you know that it’s active. From now on, any package that you install using pip will be placed in the virtenv folder, isolated from the global Python installation. You can add python packages needed in your microservice development within virtualenv.

Install python module dependencies

pip install -r requirements.txt

To start microservice

python services.py

4. How to use this service

Fire the below post request with jsonified data.Also, make sure that the specified job with the passed parameter exist on jenkins server. Refer the below example for data format.
