Guide to Start and Stop Sunbird Ed environments
- Santhosh Gandham
We have created jenkins jobs to start and stop the env which includes Kubernetes (AKS) cluster and Virtual machines in Azure
To start the environment, first start the virtual machines and then start AKS as databases need to be available for the application to start running otherwise it will end up with too many pod restarts
To stop the environment, stop the AKS cluster first and then stop the virtual machines where non-containerised workloads are runnning.
How it works:
We have created the service principle in azure which has access to start and stop the resources. Created Jenkins pipelines which leverages az cli commands to stop and start the resources using the service principle
You need to create job under OpsAdminstration Folder inside Jenkins(also you can create anywhere according to your usecase)
Jenkins pipeline to stop azure VM’s :
pipeline {
agent any
environment {
SP_CRED = credentials('stag_az_sp') // Azure SP credentials
TENANT_ID = "" // Azure Tenant ID to login
RG = "" // Azure Resource Group
AZURE_CONFIG_DIR = "/var/lib/jenkins/Azure/Staging" // Azure config dir to store session
}
stages {
stage('Stop Azure VMs') {
steps {
script {
sh 'az login --service-principal -u ${SP_CRED_USR} -p ${SP_CRED_PSW} --tenant ${TENANT_ID}'
//sh "/usr/bin/az vm list -g $RG --query '[].id' -o tsv"
sh 'az vm deallocate --ids $(az vm list -g $RG --query "[].id" -o tsv)'
}
echo "All VMs in $RG have been stopped."
echo "logging out"
sh 'az logout'
}
}
}
}
Jenkins pipeline to stop AKS cluster:
pipeline {
agent any
environment {
SP_CRED = credentials('dev_az_sp') // Azure SP credentials
TENANT_ID = "" // Azure Tenant ID to login
RG = "" // Azure Resource Group
AZURE_CONFIG_DIR = "/var/lib/jenkins/Azure/Dev" // Azure config dir to store session
}
stages {
stage('Start Azure AKS') {
steps {
script {
def AKS_CLUSTER = [ 'dev-k8s']
sh 'az login --service-principal -u ${SP_CRED_USR} -p ${SP_CRED_PSW} --tenant ${TENANT_ID}'
for (def aksName in AKS_CLUSTER) {
sh "az aks stop --name ${aksName} --resource-group ${RG}"
echo "$aksName is being stopped"
}
echo "logging out"
sh 'az logout'
}
}
}
}
}
Jenkins pipeline to start AKS cluster:
pipeline {
agent any
environment {
SP_CRED = credentials('dev_az_sp') // Azure SP credentials
TENANT_ID = "4836227a-1ace-434f-b54c-8a7a14a0b449" // Azure Tenant ID to login
RG = "sunbird-devnew-env" // Azure Resource Group
AZURE_CONFIG_DIR = "/var/lib/jenkins/Azure/Dev" // Azure config dir to store session
}
stages {
stage('Start Azure AKS') {
steps {
script {
def AKS_CLUSTER = ['dev-k8s'] // k8s Cluster Name which needs to start
sh 'az login --service-principal -u ${SP_CRED_USR} -p ${SP_CRED_PSW} --tenant ${TENANT_ID}'
for (def aksName in AKS_CLUSTER) {
sh "az aks start --name $aksName --resource-group ${RG}"
echo "$aksName is being started"
}
echo "logging out"
sh 'az logout'
}
}
}
}
}
Jenkins pipeline to start VM’s in a resource group:
pipeline {
agent any
environment {
SP_CRED = credentials('dev_az_sp') // Azure SP credentials
TENANT_ID = "4836227a-1ace-434f-b54c-8a7a14a0b449" // Azure Tenant ID to login
RG = "sunbird-devnew-env" // Azure Resource Group
AZURE_CONFIG_DIR = "/var/lib/jenkins/Azure/Dev" // Azure config dir to store session
}
stages {
stage('Start Azure VMs') {
steps {
script {
sh 'az login --service-principal -u ${SP_CRED_USR} -p ${SP_CRED_PSW} --tenant ${TENANT_ID}'
sh 'az vm start --ids $(az vm list -g $RG --query "[].id" -o tsv)'
}
echo "All VMs in $RG have been started."
echo "logging out"
sh 'az logout'
echo "sleep for 10 minutes for the VMs to start"
sh 'sleep 10m'
}
}
}
}You can schedule these jobs as a cron from jenkins job configuration
Path for these Jenkins Jobs are under OpsAdministration/dev(your env name)/Core/
