Containership Agent

Development Locally

Prerequisite

• Running Kubernetes (minikube, GKE, etc) and have access to the config
• Golang installed
  • https://golang.org/doc/install
• glide installed
  • brew install glide - or - curl https://glide.sh/get | sh

Up and Running

glide install -v

kubectl apply -f deploy/common

#Runs coordinator
go install cmd/cloud_coordinator/coordinator.go && CONTAINERSHIP_CLOUD_CLUSTER_API_KEY=$CONTAINERSHIP_CLOUD_CLUSTER_API_KEY \
CONTAINERSHIP_CLOUD_ORGANIZATION_ID=$CONTAINERSHIP_CLOUD_ORGANIZATION_ID CONTAINERSHIP_CLOUD_CLUSTER_ID=$CONTAINERSHIP_CLOUD_CLUSTER_ID \
KUBECONFIG=$HOME/.kube/config CONTAINERSHIP_CLOUD_SERVER_PORT=$PORT $GOBIN/coordinator```

#Runs agent
go install cmd/cloud_agent/agent.go && CONTAINERSHIP_CLOUD_CLUSTER_API_KEY=$CONTAINERSHIP_CLOUD_CLUSTER_API_KEY \
CONTAINERSHIP_CLOUD_ORGANIZATION_ID=$CONTAINERSHIP_CLOUD_ORGANIZATION_ID CONTAINERSHIP_CLOUD_CLUSTER_ID=$CONTAINERSHIP_CLOUD_CLUSTER_ID \
KUBECONFIG=$HOME/.kube/config $GOBIN/agent

Running images

Set up

• Running Kubernetes (minikube, GKE, etc) and have access to the config
  • kubectl config use-context minikube #can be any cluster you wish
• Fill in containership-env-configmap.yaml values
• If you are using a GKE cluster, or a cluster with RBAC you will need to give the service account launching manifests access to talk to the kubernetes api
  • kubectl apply -f deploy/rbac

Up and Running

make coordinator

make agent

Releases

Rough process is as follows (TODO make this more clear):

1. Create release-* branch if it doesn't exist, e.g. release-2.x
2. Cherry-pick commits from master to release-* branch as necessary (or PR, but ensure no merge commits)
3. Tag, e.g. git tag -a v2.0.0 -m "Release v2.0.0" - please don't forget -a as it's important we annotate our tags
4. Push release branch and tag to upstream
5. git checkout v2.0.0
6. git clean -fdx - optional and be careful obviously, but good for sanity
7. make release - will fail if you're not on a tag or tree is dirty
8. Push tagged agent and coordinator docker images to DockerHub
9. Bump version to ship in cloud.api
