- 3. What´s Gocd GoCD is an open source tool which is used in software development to achieve continuous delivery (CD) of software. It supports automating the entire build-test-release process from code check-in to deployment. It helps to keep producing valuable software in short cycles and ensure that the software can be reliably released at any time.
- 4. Gocd - Benefits • Pipeline Based • Agent based • Parallel and Sequential execution • End-to-end workflow • GoCD's agent grid provides parallel and cross-platform execution • Numerous plug-ins • Simple Exceptions and Error Handling • Flexible to setup any deploy • Excellent API Reference
- 5. Gocd Concepts I • Environments • Pipelines • Stages • Job • Tasks • Agents
- 10. Gocd Concepts VI
- 11. Tasks conditions
- 12. Timeout and scheduling job
- 13. Stage Settings
- 16. Step by step • 1 - Start a gocd pipeline (manually or automatically) based a git tag or branch, kubernetes namespace or nomad job • 2 - Gocd agent is going to git clone • 3 - Gocd Agent is going to build through build process you set up • 4 – Docker build in your git dockerfile • 5 – Docker push to registry servers • 6 – Run Docker images (kubectl rollout/API) • 7 - Applications auto-registration etcd/consul • 8 – Consul/etc-templates update load balancer config file
- 17. Trigger pipeline Dev Environment Deploying new version an analyst just need to inform a git tag version and a kube namespace/nomad job name on dev environment.
- 18. Full process through pipeline/stages
- 19. Promoting applications across Environments Git Build Docker images Upload to register Rollout Testing Rollout Testing Rollout Testing Dev Environment Hmg Environment Prod Environment
- 20. HMG/PROD Deployment Deploying appplication o dev enviromment we just setup another environment just informing docker image name, its tag and kube namespace/nomad job name.
