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

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
