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.
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

Kubernetes architecture
Step by step
• 1 - Start a gocd pipeline (manually or automatically) based a git tagor 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
Trigger pipeline Dev EnvironmentDeploying new version an analyst just need to inform a git tag version and a
kube namespace/nomad job name on dev environment.
