In our June Rancher meetup, GitLab joined us to discuss how to use GitLab tools and the Rancher container management platform for an automated, scalable CI pipeline. We were also joined by the devops team at Kloeckner.i who demonstrated their real-world example of the two together.

19. Gitlab and Rancher
• Gitlab handles:
• Source code control
• Building containers
• Storing containers in the registry
• Testing and artifact storage
• Deployment through external integrations
• Rancher handles:
• Host management and container scheduling
• The complete lifecycle of resources
• Making containers available for consumers

21. Gitlab CI and Docker
• Don’t compile the toolchain into the container
• Bring the code up inside of a container that acts on the code
• Move the code to the next build stage
• Deploy the result

22. Objectives
• Save money
• Automate deployments
• Provide an environment for testing
• Make it easy

23. CI/CD Pipeline Demo (Basic)
• Prerequisites
• Create Rancher environment
• Add a host
• Add Gitlab Registry
• Deploy a stack named after group
• Deploy a service named after project
• Automation
• Upgrade service

24. CI/CD Pipeline Demo (Advanced)
• Prerequisites
• None
• Automation
• Create Rancher environment
• Launch EC2 host
• Add Gitlab Registry
• Deploy stack
• Return public endpoint
• Pause
• When ready, tear down environment

25. Resources
• Rancher Gitlab Deploy

28. CI/CD Actors
Gitlab
● Code repository
● Docker registry
● CI/CD pipelines
Gitlab docker runner
● Runs stages
● Used for: testing, building docker
images, deploying
Rancher
● API used for deploying
● Bootstraps environments
● Runs docker containers
Ruby app docker container
Shia docker container
● Create environment
● Add hosts via dockermachine
● Manage secrets
● Deploy stacks, services
● Deploy QA environments
Magic Mike
● Polls Rancher API to find hosts
for environments
● Control HAproxy: do SSL
termination, domain mapping

29. Deploy workflow to integration and production environments
git push
origin steel-1337
gitlab git
repo
run lint/tests
build
docker container
and push
gitlab docker registry
build:
image: ${CI_REGISTRY}/build_images/build_image:latest
stage: build
script:
- build_image
1. upsert environment
2. upsert hosts
3. deploy stack
Rancher API
Cattle env from template
with GCE Hosts
Stack runs in cattle env
Our customers
1. check Rancher API
2. create haproxy.cfg
QA + Jenkins
merge

30. WIP deploy QA environment (whole stack) workflow
git push origin
feature/@STEEL-1337
gitlab git
repo
run lint/tests
build
docker container
and push
gitlab docker registry
1. upsert steel-1337
environment (with
hosts)
2. create secrets
3. deploy all stacks from
stack.yml with
master
4. deploy stack that
summoned QA env with
commit
1. check Rancher API
2. create haproxy.cfg that includes
