Terraform/Kubernetes Reference Infrastructure for Cloud Posse Production Organization in AWS.

NOTE: Before creating the Production infrastructure, you need to provision the Parent ("Root") Organization in AWS (because it creates resources needed for all other accounts). Follow the steps in README first. You need to do it only once.


This project is part of our comprehensive "SweetOps" approach towards DevOps.

It's 100% Open Source and licensed under the APACHE2.

Introduction

We use geodesic to define and build world-class cloud infrastructures backed by AWS and powered by Kubernetes.

geodesic exposes many tools that can be used to define and provision AWS and Kubernetes resources.

Here is the list of tools we use to provision cloudposse.co infrastructure:

Quick Start

Setup AWS Role

NOTE: You need to do it only once.

Configure AWS profile in ~/.aws/config. Make sure to change username ([email protected]) to your own.

[profile cpco-prod-admin]
region=us-west-2
role_arn=arn:aws:iam::845778104613:role/OrganizationAccountAccessRole
mfa_serial=arn:aws:iam::323330167063:mfa/[email protected]
source_profile=cpco

Install and setup aws-vault

NOTE: You need to do it only once.

We use aws-vault to store IAM credentials in your operating system's secure keystore and then generates temporary credentials from those to expose to your shell and applications.

Install aws-vault on your local computer first.

On MacOS, you may use homebrew cask

brew cask install aws-vault

Then setup your secret credentials for AWS in aws-vault

aws-vault add --backend file cpco

NOTE: You should set AWS_VAULT_BACKEND=file in your shell rc config (e.g. ~/.bashrc) so it persists.

For more info, see aws-vault

Examples

Build Docker Image

# Initialize the project's build-harness
make init

# Build docker image
make docker/build

Install the wrapper shell

make install

Run the shell

prod.cloudposse.co

Login to AWS with your MFA device

assume-role

Populate chamber secrets

NOTE: You need to do it only once for a given set of secrets. Repeat this step if you want to add new secrets.

Populate chamber secrets for kops project (make sure to change the keys and values to reflect your environment; add new secrets as needed)

chamber write kops <key1> <value1>
chamber write kops <key2> <value2>
...

NOTE: Run chamber list -e kops to list the secrets stored for kops project

Populate chamber secrets for backing-services project (make sure to change the values to reflect your environment; add new secrets as needed)

chamber write backing-services TF_VAR_POSTGRES_ADMIN_NAME admin
chamber write backing-services TF_VAR_POSTGRES_ADMIN_PASSWORD supersecret
chamber write backing-services TF_VAR_POSTGRES_DB_NAME app

NOTE: Run chamber list -e backing-services to list the secrets stored for backing-services project

NOTE: Before provisioning AWS resources with Terraform, you need to create tfstate-backend first (S3 bucket to store Terraform state and DynamoDB table for state locking).

Follow the steps in this README. You need to do it only once.

After tfstate-backend has been provisioned, follow the rest of the instructions in the order shown below.

Provision dns with Terraform

Change directory to dns folder

cd /conf/dns

Run Terraform

init-terraform
terraform plan
terraform apply

For more info, see geodesic-with-terraform

Provision cloudtrail with Terraform

cd /conf/cloudtrail
init-terraform
terraform plan
terraform apply

Provision acm with Terraform

cd /conf/acm
init-terraform
terraform plan
terraform apply

Provision chamber with Terraform

cd /conf/chamber
init-terraform
terraform plan
terraform apply

Makefile Targets

Available targets:

  all                                 Initialize build-harness, install deps, build docker container, install wrapper script and run shell
  build                               Build docker image
  deps                                Install dependencies (if any)
  help                                This help screen
  help/all                            Display help for all targets
  install                             Install wrapper script from geodesic container
  push                                Push docker image to registry
  run                                 Start the geodesic shell by calling wrapper script

Provision the Kops cluster

We create a kops cluster from a manifest.

The manifest template is located in /templates/kops/default.yaml and is compiled by running build-kops-manifest in the Dockerfile.

Provisioning a kops cluster takes three steps:

  1. Provision the kops backend (config S3 bucket, cluster DNS zone, and SSH keypair to access the k8s masters and nodes) in Terraform
  2. Update the Dockerfile and rebuild/restart the geodesic shell to generate a kops manifest file
  3. Execute the kops manifest file to create the kops cluster

Change directory to kops folder

cd /conf/kops

Run Terraform to provision the kops backend (S3 bucket, DNS zone, and SSH keypair)

init-terraform
terraform plan
terraform apply

From the Terraform outputs, copy the zone_name and bucket_name into the ENV vars KOPS_CLUSTER_NAME and KOPS_STATE_STORE in the Dockerfile.

The Dockerfile kops config should look like this:

# kops config
ENV KOPS_CLUSTER_NAME="us-west-2.prod.cloudposse.co"
ENV KOPS_DNS_ZONE=${KOPS_CLUSTER_NAME}
ENV KOPS_STATE_STORE="s3://cpco-prod-kops-state"
ENV KOPS_STATE_STORE_REGION="us-west-2"
ENV KOPS_AVAILABILITY_ZONES="us-west-2a,us-west-2b,us-west-2c"
ENV KOPS_BASTION_PUBLIC_NAME="bastion"
ENV BASTION_MACHINE_TYPE="t2.medium"
ENV MASTER_MACHINE_TYPE="t2.large"
ENV NODE_MACHINE_TYPE="t2.large"
ENV NODE_MAX_SIZE="3"
ENV NODE_MIN_SIZE="3"

Type exit (or hit ^D) to leave the shell.

Note, if you've assumed a role, you'll first need to leave that also by typing exit (or hit ^D).

Rebuild the Docker image

Provision vpc from backing-services with Terraform

NOTE: We provision backing-services in two phases because:

  • aurora-postgres and elasticache-redis depend on vpc-peering (they use kops Security Group to allow kops applications to connect)
  • vpc-peering depends on vpc and kops (it creates a peering connection between the two networks)

To break the circular dependencies, we provision kops, then vpc (from backing-services), then vpc-peering, and finally the rest of backing-services (aurora-postgres and elasticache-redis).

NOTE: We use chamber to first populate the environment with the secrets from the specified service (backing-services) and then execute the given commands (terraform plan and terraform apply)

cd /conf/backing-services
init-terraform
chamber exec backing-services -- terraform plan -target=module.identity -target=module.vpc -target=module.subnets
chamber exec backing-services -- terraform apply -target=module.identity -target=module.vpc -target=module.subnets

Provision vpc-peering from kops-aws-platform with Terraform

cd /conf/kops-aws-platform
init-terraform
terraform plan -target=module.identity -target=data.aws_vpc.backing_services_vpc -target=module.kops_vpc_peering
terraform apply -target=module.identity -target=data.aws_vpc.backing_services_vpc -target=module.kops_vpc_peering

Provision the rest of kops-aws-platform with Terraform

cd /conf/kops-aws-platform
terraform plan
terraform apply

Provision the rest of backing-services with Terraform

NOTE: We use chamber to first populate the environment with the secrets from the specified service (backing-services) and then execute the given commands (terraform plan and terraform apply)

cd /conf/backing-services
chamber exec backing-services -- terraform plan
chamber exec backing-services -- terraform apply

Provision Kubernetes Resources with Helmfile

We use helmfile to deploy Helm charts to provision Kubernetes resources.

helmfile.yaml is located in the /conf/kops directory in geodesic container (see helmfile.yaml).

Change the current directory to kops

cd /conf/kops

Deploy the Helm charts

NOTE: We use chamber to first populate the environment with the secrets from the kops service and then execute the given command (helmfile sync)

kops export kubecfg $KOPS_CLUSTER_NAME
chamber exec kops -- helmfile sync
