Manual Approval and Telegram Notifications in Jenkins

Why use a manual approval step in the deploy code?

Manual approval in Jenkins provides a mechanism to ensure quality, security and compliance in software development and deployment processes.

Manual approval

Add this stage to the pipeline

 stage('Approval') { steps { timeout(time: 15, unit: "MINUTES") { input message: 'Do you want to approve the deployment?', ok: 'Yes' } echo "Initiating deployment" } }

Telegram Notifications

To send notifications we need two things
First: HTTP_API of bot
Second: CHAT_ID

HTTP_API of bot

Create telegram bot
1. BotFather in Telegram (@botfather)
2. Send /newbot command
3. Enter bot name and bot username
token-http-api

CHAT_ID
1. Go to @myidbot
2. Enter: /start -> /getid
3. Save your chat_ID

Creating Jenkins Global Credentials

Manage Jenkins -> Credentials -> System -> Global credentials (unrestricted)
Add Crediantials(CHAT_ID & TELEGRAM_API)

Configurig pipeline

_At the top of the pipeline

environment { // Telegram configuration TOKEN = credentials('telegram-api') CHAT_ID = credentials('telegram_chatid') }

Declare two variables which contain the tokens

 post { success { script { sh "curl -X POST -H 'Content-Type: application/json' -d '{\"chat_id\": \"${CHAT_ID}\", \"text\": \"${JOB_NAME}: #${BUILD_NUMBER}\n✅ Deploy succeeded! \", \"disable_notification\": false}' \"https://api.telegram.org/bot${TOKEN}/sendMessage\"" } } failure { script { sh "curl -X POST -H 'Content-Type: application/json' -d '{\"chat_id\": \"${CHAT_ID}\", \"text\": \"${JOB_NAME}: #${BUILD_NUMBER}\n❌Deploy failure!\", \"disable_notification\": false}' \"https://api.telegram.org/bot${TOKEN}/sendMessage\"" } } aborted { script { sh "curl -X POST -H 'Content-Type: application/json' -d '{\"chat_id\": \"${CHAT_ID}\", \"text\": \"${JOB_NAME}: #${BUILD_NUMBER}\n❌Deploy aborted!\", \"disable_notification\": false}' \"https://api.telegram.org/bot${TOKEN}/sendMessage\"" } } }
