Managing Release on GITHUB

I was working around a few days back, managing the release of the project with versioning and proper tags associated with it which results in writing the python code.

I have written a simple python function that will call the API of GitHub and will Create/Fetch /Delete the release on GitHub.

Note** You can manage the same with CURL command too but I was facing some authentication issue, so haven’t done, I haven’t tried with explicitly passing the auth token in header by -H tag, you can give a try.

Have a look at the below snippet of code which can be easily integrated with Jenkins pipeline

import requests
import json

user = ""             #username of github account
repo = ""             #repository_name
auth = ""             #authentication token
url = ""
header = {"Authorization": "token %s" %(auth), 'Accept': 'application/vnd.github.v3.raw'}
tag_name = ""         #tag_name of release
releaseId = ""        #releaseID
Enter fullscreen mode Exit fullscreen mode

Here, tag_name and releaseId variables are only required if you want to delete a particular release, which you will rarely come across.

# Fetch latest release from github
def latestRelease():
        releases = requests.get('%s/repos/%s/%s/releases/latest' %(url,user,repo), headers=header).json()
        print(releases['tag_name'], releases['id'])
        print('Release Not Found')
Enter fullscreen mode Exit fullscreen mode

The above code will be used to fetch the latest release present on GitHub.

# Create latest release on github
def postNewrelease():
        with open('release.json') as newRelease:
            _release = json.load(newRelease)
            release_new ='%s/repos/%s/%s/releases' %(url,user,repo), json=_release, headers=header).json()
        print("error while creating new release")
Enter fullscreen mode Exit fullscreen mode

This snippet of code is used to create the release on GitHub, which contains payload in JSON format.

release.json will look something like below,

        "tag_name": "v1.6.0",
        "target_commitish": "master",
        "name": "v1.6.0",
        "body": "nikhil python api call release",
        "draft": false,
        "prerelease": false

Enter fullscreen mode Exit fullscreen mode

Even with this payload, you can easily create prerelease of the master branch, which can be tested in the Staging environment.

# Delete release from github by passing tag_name & releaseId
def deleterelease():
        releaseDeleteTag = requests.delete('%s/repos/%s/%s/git/refs/tags/%s' %(url,user,repo,tag_name), headers=header)
        releaseDeleteId = requests.delete('%s/repos/%s/%s/releases/%s' %(url,user,repo,releaseId), headers=header)
        print("error wile deleting release")
Enter fullscreen mode Exit fullscreen mode

The above deletion method is not often required.

The full script is available in the below repository.

Feel free to comment below, if you will found any mistakes or required any type of modifications/enhancement. The code is fully tested so hopefully, you will not find any issues.
