An introduction to CI/CD

1. End-to-end CI/CD deployments of a containerized app

3. I built a demo/test app (Yelb)
https://github.com/mreferre/yelb

4. Occasionally I’d run a …
Docker build -t mreferre/yelb-ui:whatevertag .

5. Who cares if…
• The master branch is several releases ahead of the artifact (i.e. docker image)?
• I don’t document how to build artifacts (hint: it’s just a docker build command).

6. Then a couple of things happened
……….

7. From Docker Hub

8. How to deploy on diff abstractions?
AWS
Lambda
Amazon
EC2
Metal
Amazon
EKS
physicalseverVMcontainerfunction
Levelofabstraction
Provider space
(managed by AWS)
Consumer space
(managed by the customer)
Amazon
ECS

9. How about the serverless deployment model?

10. The Lambda artifact(s)
git clone http://github.com/mreferre/devnull
cd ./devnull/yelb-appserver
docker run -v "$PWD":/var/task -it lambci/lambda:build-ruby2.5 /bin/bash -c "yum -y
install postgresql-devel postgresql-libs ; bundle config --delete frozen ; bundle install ;
bundle install --deployment; mkdir lib; cp /usr/lib64/libpq.so.5 ./lib/libpq.so.5"
zip -r yelb-appserver-lambda-200v2.zip getvotes_adapter.rb getstats_adapter.rb
pageviews_adapter.rb hostname_adapter.rb restaurant_adapter.rb vendor modules lib
aws s3 cp yelb-appserver-lambda.zip s3://bucketname

11. How can you make all this better?

12. Perhaps I should use CI/CD for my hobby project?

14. The output of a stage is the input for the next

15. Before we start
• I am showing you the process in pieces (and then we will tie everything together)
• This is going to be a basic commit -> build -> deploy setup
• You can consider it the basis for more complex pipelines/workflows
• I am not including a test phase (you should)
• I am not firing up any pre-deploy / post-deploy check scripts (you could)
• AWS tool can be replaced w/ third party tools in each area
• e.g. GitHub Vs CodeCommit

16. “Fun” facts
• No EC2 instances have been harmed used in this setup (Code* + ECS + Fargate)
• The AWS documentation is fairly good but these are good resources as well
• Autocorrect (Yelb -> Yell) is your friend if you want to waste 6 hours debugging
