Azure DevOps Service Connections

• Lets create a service connection to docker hub
• Navigate to Project Settings => Service Connections
  
  
  
• Effective Pipeline

          Dockerfile: '**/Dockerfile'
          tags: "$(Build.BuildId)"

• After every build we should see a docker image tag being published
  

using variables and parameters in Azure DevOps Pipelines

• Refer Here for parameters and Refer Here for parameter yaml schema
• Paramter types: Refer Here
• We have added a parameter for container registry

* We use paramters to give flexibility to the user to change values

• User Defined Variables Refer Here
• Refer Here for yaml schema
• We have added a simple variable for docker file location

• To use variables we have 3 syntaxes Refer Here
  

Multi Stage pipeline

• The basic pipeline
  
• Manual steps

# Remove all contianer
docker container rm -f $(docker container ls -a -q)
# remove all images
docker image rm -f $(docker image ls -q)
docker container run -d --name nop -P shaikkhajaibrahim/nopfromado
