Trigger the pipeline¶
Time Estimate: 15 - 20 minutes
To trigger the pipeline, push the master branch to the remote as follows:
git push -u origin master
The pipeline will pull the code, build the docker image, push it to ECR, and deploy it to your ECS cluster. This will take a few minutes. You can monitor the pipeline in the AWS CodePipeline console.
Test the application¶
From the output of the Terraform build, note the Terraform output alb_address.
cd ../terraform
export tf_alb_address=$(terraform output alb_address)
echo $tf_alb_address
Use this in your browser to access the application.
Push a change through the pipeline and re-test¶
The pipeline can now be used to deploy any changes to the application.
You can try this out by changing the welcome message as follows:
cd ../petclinic
vi src/main/resources/messages/messages.properties
Commit the change:
git add .
git commit -m "Changed welcome string"
Push the change to trigger pipeline:
git push origin master
As before, you can use the console to observe the progression of the change through the pipeline. Once done, verify that the application is working with the modified welcome message.
