# Cats and Dogs Labs
Refer to the following headings when working through the content and getting stuck.
## Auto Scaling > Service Auto Scale > Service Load Test
The load test example looks like this;
`siege -c 200 -i [Your ALB DNS name] + '/'`
this should be interpreted with your DNS ELB name like the following;
`siege -c 200 -i http://demogo-alb-1631020000.us-west-2.elb.amazonaws.com/`
**NOTE**: Make sure that '/' is at the end of the ALB DNS name, because the web service is bound to the default path (/). Without it, the traffic burst will not hit our web application
## Auto Scaling > Cluster Auto Scale > Cluster Load Test
The load test example looks like this;
`siege -c 500 -i [Your ALB DNS name] + /`
You will get warning message from siege saying it can only do 255 concurrent sessions without changing a configuration file. This will be enough to force a scaling event in the cluster. Continue with the test.
## CI/CD > AWS CodeCommit
If you don't see any files give the UI 1-2 minutes to catch up on the first push.
## CI/CD > CodePipeline Setting
### Get Account Information
If you do not know how to get your `<YOUR REGION>` and `<YOUR ACCOUNT ID>`, then perform the following in the Cloud9 terminal;
```bash=
echo ${AWS_REGION} && echo ${AWS_ACCOUNT_ID}
```
Update your build spec lines `7` & `8`, then save the file.
### Build Step Failure
Check 1 - Review the build logs
If your build step fails, make sure you have updated the IAM role to include the required permissions and then retry the step.
Check 2 - Review the build logs
Check if your buildspec.yml has been pushed to your repository using cloud9.
> [Container] 2023/06/06 02:55:00 Phase context status code: YAML_FILE_ERROR Message: YAML file does not exist
If it hasn't perform the following in Cloud9 terminal:
```bash=
cd ~/environment/dogs
git add buildspec.yml
git commit -m "add buildspec.yml"
git push
```
Navigate back to the *dogs-cicd* Pipeline you will see the Build is 'in progress', this is because it has been triggered by the source repository event from the *git push* in the previous step.

## CI/CD Deploy Test
You may notice that index.html has changed since the last revision of the workshop. The column 17 doesn't match where the H1 tag is. Instead update the H1 tag on column 23

**This is the end of the workshop material** the rest of this page is dedicated to useful links and best practices for Amazon ECS that I find useful for sharing with customers. It gets updated over time.
