keto

Keto is under development and should not be used or treated as working software. Everything will probably change.

Pre-requisites

Install golang

Keto is built against the latest golang which can be installed from https://golang.org/dl/.

Building keto

Get the source code:

$ go get -u github.com/UKHomeOffice/keto/cmd/keto

First install Glide - https://github.com/Masterminds/glide#install.

Get the correct dependency versions:

cd ${GOPATH}/src/github.com/UKHomeOffice/keto
glide install

Build the binary:

go build -v github.com/UKHomeOffice/keto/cmd/keto

Cloud resources

AWS

You will need the following AWS resources created in advance:

  1. An existing VPC
  2. Subnet(s) A minimum of one subnet is required
  3. An AWS defined EC2 "keypair" ssh-key

Usage

Help

keto --help

Create Cluster

You will need to create or obtain suitable CA certs before running keto. Minimal command to create a Kubernetes cluster in AWS:

keto create cluster testcluster --ssh-key my-aws-key-name --networks subnet-awsid --machine-type t2.medium --cloud aws

This will create a cluster and an ELB serving the Kubernetes API.

List Clusters

keto get cluster --cloud aws

Delete a cluster

keto delete cluster --name testcluster --cloud aws

Create Expected CA Files

  1. Retrieve the prerequisite libraries: go get -u github.com/cloudflare/cfssl/cmd/...
  2. Set an environment variable for the keto assets directory KETO_ASSETS_DIR (defaults to ${PWD})
  3. Create the required ca key and crt files (etcd, kube): ./bin/create_ca_files.sh

Run End to End Tests

The e2e tests can be run in CI using the following command:

drone deploy -p E2E=true UKHomeOffice/keto <build-number> e2e

The following environment variables must be set for the e2e tests to execute successfully:
