Ops Manager Automation - One pipeline to rule them all

What is this?

The following steps use Control Tower to build a Concourse instance on Google Cloud Platform, then uses a combination of GCS buckets, Credhub, a suite of Platform Automation tools and a single Concourse pipeline to deploy (and upgrade) the entire OpsMan and PCF product stack directly from the Pivotal Network.

This fork was adapted to use a terraform script that paves both Pivotal Application Service and Pivotal Container Service, and an updated pipeline that runs both products on the same Ops Manager.

Recycling GCP projects

If you wish to re-use an existing GCP project for this exercise, it is often useful to clean up any existing resources beforehand. For guidance, follow these instructions.

Create your jumpbox from your local machine or Google Cloud Shell

GCP_PROJECT_ID=<TARGET_GCP_PROJECT_ID>
GCP_REGION=<TARGET_REGION>
gcloud auth login --project ${GCP_PROJECT_ID} --quiet # ... if necessary

gcloud services enable compute.googleapis.com \
  --project "${GCP_PROJECT_ID}"

gcloud compute instances create "jbox-cc" \
  --image-project "ubuntu-os-cloud" \
  --image-family "ubuntu-1804-lts" \
  --boot-disk-size "200" \
  --machine-type=g1-small \
  --project "${GCP_PROJECT_ID}" \
  --zone "${GCP_REGION}"-a

Move to the jumpbox and log in to GCP

gcloud compute ssh ubuntu@jbox-cc \
  --project "${GCP_PROJECT_ID}" \
  --zone "${GCP_REGION}"-a

gcloud auth login --quiet

All following commands should be executed from the jumpbox unless otherwsie instructed.

Prepare your environment file

cat > ~/.env << EOF
# *** your environment-specific variables will go here ***
PIVNET_UAA_REFRESH_TOKEN=CHANGE_ME_PIVNET_UAA_REFRESH_TOKEN  # e.g. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-r
PCF_DOMAIN_NAME=CHANGE_ME_DOMAIN_NAME                        # e.g. "mydomain.com", "pal.pivotal.io", "pivotaledu.io", etc.
PCF_SUBDOMAIN_NAME=CHANGE_ME_SUBDOMAIN_NAME                  # e.g. "mypks", "mypas", "cls66env99", "maroon", etc.
GITHUB_PUBLIC_REPO=CHANGE_ME_GITHUB_PUBLIC_REPO              # e.g. https://github.com/amcginlay/ops-manager-automation-cc.git
GCP_REGION=CHANGE_ME_GCP_REGION                              # e.g. europe-west2, us-central1 etc.
GCP_AZ1=CHANGE_ME_GCP_AZ1                              # e.g. europe-west2-a, us-central1-a etc.
GCP_AZ2=CHANGE_ME_GCP_AZ2                              # e.g. europe-west2-b, us-central1-b etc.
GCP_AZ3=CHANGE_ME_GCP_AZ3                              # e.g. europe-west2-c, us-central1-c etc.
PRODUCT_SLUG=pivotal-cloud-foundry

export OM_TARGET=https://opsman.\${PCF_SUBDOMAIN_NAME}.\${PCF_DOMAIN_NAME}
export OM_USERNAME=admin
export OM_PASSWORD=$(uuidgen)
export RABBITMQ_MULTITENANT_ADMIN_PASSWORD=$(uuidgen)
export OM_DECRYPTION_PASSPHRASE=\${OM_PASSWORD}
export OM_SKIP_SSL_VALIDATION=true
EOF

Before continuing, open the .env file and update the CHANGE_ME values accordingly.

Ensure these variables get set into the shell every time the ubuntu user connects to the jumpbox:

echo "source ~/.env" >> ~/.bashrc

Load the variables into your shell with the source command so we can use them immediately:

source ~/.env

Prepare jumpbox and generate service account

Clone this repo

The scripts, pipelines and config you need to complete the following steps are inside this repo, so clone it to your jumpbox:

git clone ${GITHUB_PUBLIC_REPO} ~/ops-manager-automation-cc

Create a self-signed certificate

Run the following script to create a certificate and key for the installation:

DOMAIN=${PCF_SUBDOMAIN_NAME}.${PCF_DOMAIN_NAME} ~/ops-manager-automation-cc/bin/mk-ssl-cert-key.sh

Configure Terraform

cat > ~/terraform.tfvars <<-EOF
dns_suffix             = "${PCF_DOMAIN_NAME}"
env_name               = "${PCF_SUBDOMAIN_NAME}"
region                 = "${GCP_REGION}"
zones                  = ["${GCP_AZ1}", "${GCP_AZ2}", "${GCP_AZ3}"]
project                = "$(gcloud config get-value core/project)"
opsman_image_url       = ""
opsman_vm              = 0
create_gcs_buckets     = "false"
external_database      = 0
isolation_segment      = 0
ssl_cert            = <<SSL_CERT
$(sudo cat /etc/letsencrypt/live/${PCF_SUBDOMAIN_NAME}.${PCF_DOMAIN_NAME}/fullchain.pem)
SSL_CERT
ssl_private_key     = <<SSL_KEY
$(sudo cat /etc/letsencrypt/live/${PCF_SUBDOMAIN_NAME}.${PCF_DOMAIN_NAME}/privkey.pem)
SSL_KEY
service_account_key = <<SERVICE_ACCOUNT_KEY
$(cat ~/gcp_credentials.json)
SERVICE_ACCOUNT_KEY
EOF

Note the opsman_image_url == "" setting which prohibits Terraform from downloading and deploying the Ops Manager VM. The Concourse pipelines will take responsibility for this.

Terraform the infrastructure

The PKS and PAS platforms have different baseline infrastructure requirements which are configured from separate dedicated directories. Terraform is directory-sensitive and needs local access to your customized terraform.tfvars files so symlink it in from the home directory.

cd ~/terraforming/terraforming-pcf
ln -s ~/terraform.tfvars .

Launch Terraform

Confirm you're in the correct directory for your chosen platform and terraform.tfvars is present, then execute the following:

terraform init
terraform apply --auto-approve

This will take about 2 mins to complete.

Install Concourse

We use Control Tower to install Concourse, as follows:

GOOGLE_APPLICATION_CREDENTIALS=~/gcp_credentials.json \
  control-tower deploy \
    --region ${GCP_REGION} \
    --iaas gcp \
    --workers 2 \
    --domain concourse.${PCF_SUBDOMAIN_NAME}.${PCF_DOMAIN_NAME} \
    ${PCF_SUBDOMAIN_NAME}

This will take about 20 mins to complete.

Persist a few credentials

INFO=$(GOOGLE_APPLICATION_CREDENTIALS=~/gcp_credentials.json \
  control-tower info \
    --region ${GCP_REGION} \
    --iaas gcp \
    --json \
    ${PCF_SUBDOMAIN_NAME}
)

echo "CC_ADMIN_PASSWD=$(echo ${INFO} | jq --raw-output .config.concourse_password)" >> ~/.env
echo "CREDHUB_CA_CERT='$(echo ${INFO} | jq --raw-output .config.credhub_ca_cert)'" >> ~/.env
echo "CREDHUB_CLIENT=credhub_admin" >> ~/.env
echo "CREDHUB_SECRET=$(echo ${INFO} | jq --raw-output .config.credhub_admin_client_secret)" >> ~/.env
echo "CREDHUB_SERVER=$(echo ${INFO} | jq --raw-output .config.credhub_url)" >> ~/.env
echo 'eval "$(GOOGLE_APPLICATION_CREDENTIALS=~/gcp_credentials.json \
  control-tower info \
    --region ${GCP_REGION} \
    --iaas gcp \
    --env ${PCF_SUBDOMAIN_NAME})"' >> ~/.env

source ~/.env

Verify BOSH and Credhub connectivity

bosh env
credhub --version

Check Concourse targets and check the pre-configured pipeline:

fly targets
fly -t control-tower-${PCF_SUBDOMAIN_NAME} pipelines

Navigate to the url shown for fly targets.

Use admin user and the value of CC_ADMIN_PASSWD to login and see the pre-configured pipeline.

Note control-tower will log you in but valid access tokens will expire every 24 hours. The command to log back in is:

fly -t control-tower-${PCF_SUBDOMAIN_NAME} login --insecure --username admin --password ${CC_ADMIN_PASSWD}

Set up dedicated GCS bucket for downloads

gsutil mb -c regional -l ${GCP_REGION} gs://${PCF_SUBDOMAIN_NAME}-concourse-resources
gsutil versioning set on gs://${PCF_SUBDOMAIN_NAME}-concourse-resources

Add a dummy state file

The state.yml file is produced by the create-vm platform automation task and serves as a flag to indicate that an Ops Manager exists. We currently store the state.yml file in GCS. The install-opsman job also consumes this file so it can short-circuit the create-vm task if an Ops Manager does exist. This is a mandatory input and does not exist by default so we create a dummy state.yml file to kick off proceedings. Storing the state.yml file in git may work around this edge case but, arguably, GCS/S3 is a more appropriate home.

echo "---" > ~/state.yml
gsutil cp ~/state.yml gs://${PCF_SUBDOMAIN_NAME}-concourse-resources/

If required, be aware that versioned buckets require you to use gsutil rm -a to take files fully out of view.

Store secrets in Credhub

credhub set -n pivnet-api-token -t value -v "${PIVNET_UAA_REFRESH_TOKEN}"
credhub set -n domain-name -t value -v "${PCF_DOMAIN_NAME}"
credhub set -n subdomain-name -t value -v "${PCF_SUBDOMAIN_NAME}"
credhub set -n gcp-project-id -t value -v "$(gcloud config get-value core/project)"
credhub set -n opsman-public-ip -t value -v "$(dig +short opsman.${PCF_SUBDOMAIN_NAME}.${PCF_DOMAIN_NAME})"
credhub set -n gcp-credentials -t value -v "$(cat ~/gcp_credentials.json)"
credhub set -n om-target -t value -v "${OM_TARGET}"
credhub set -n om-skip-ssl-validation -t value -v "${OM_SKIP_SSL_VALIDATION}"
credhub set -n om-username -t value -v "${OM_USERNAME}"
credhub set -n om-password -t value -v "${OM_PASSWORD}"
credhub set -n om-decryption-passphrase -t value -v "${OM_DECRYPTION_PASSPHRASE}"
#credhub set -n domain-crt-ca -t value -v "$(cat ~/certs/${PCF_SUBDOMAIN_NAME}.${PCF_DOMAIN_NAME}.ca.crt)"
credhub set -n domain-crt -t value -v "$(sudo cat /etc/letsencrypt/live/${PCF_SUBDOMAIN_NAME}.${PCF_DOMAIN_NAME}/fullchain.pem)"
credhub set -n domain-key -t value -v "$(sudo cat /etc/letsencrypt/live/${PCF_SUBDOMAIN_NAME}.${PCF_DOMAIN_NAME}/privkey.pem)"
credhub set -n region -t value -v "${GCP_REGION}"
credhub set -n az1 -t value -v "${GCP_AZ1}"
credhub set -n az2 -t value -v "${GCP_AZ2}"
credhub set -n az3 -t value -v "${GCP_AZ3}"
credhub set -n rabbitmq-multitenant-password -t value -v "${RABBITMQ_MULTITENANT_ADMIN_PASSWORD}"

Take a moment to review these settings with credhub get -n <NAME>.

Build the pipeline

Create a private.yml to contain the secrets required by pipeline.yml:

cat > ~/private.yml << EOF
---
product-slug: ${PRODUCT_SLUG}
config-uri: ${GITHUB_PUBLIC_REPO}
gcp-credentials: |
$(cat ~/gcp_credentials.json | sed 's/^/  /')
gcs-bucket: ${PCF_SUBDOMAIN_NAME}-concourse-resources
pivnet-token: ${PIVNET_UAA_REFRESH_TOKEN}
credhub-ca-cert: |
$(echo $CREDHUB_CA_CERT | sed 's/- /-\n/g; s/ -/\n-/g' | sed '/CERTIFICATE/! s/ /\n/g' | sed 's/^/  /')
credhub-client: ${CREDHUB_CLIENT}
credhub-secret: ${CREDHUB_SECRET}
credhub-server: ${CREDHUB_SERVER}
EOF

Set and unpause the pipelines:

Create the "fetch artifacts" pipeline. You want this pipeline separate from your main pipeline because you are less likely to destroy it and it can work in parallel to the master pipeline

fly -t control-tower-${PCF_SUBDOMAIN_NAME} set-pipeline -p fetch-artifacts -n   -c ~/ops-manager-automation-cc/ci/fetch-artifacts/pipeline.yml -l ~/private.yml 

fly -t control-tower-${PCF_SUBDOMAIN_NAME}  unpause-pipeline -p fetch-artifacts

Run the master pipeline with the commands below:

fly -t control-tower-${PCF_SUBDOMAIN_NAME} set-pipeline -p ${PRODUCT_SLUG} -n \
  -c ~/ops-manager-automation-cc/ci/${PRODUCT_SLUG}/pipeline.yml \
  -l ~/private.yml

fly -t control-tower-${PCF_SUBDOMAIN_NAME} unpause-pipeline -p ${PRODUCT_SLUG}

This should begin to execute in ~60 seconds.

Be aware that you may be required to manually accept the PivNet EULAs before a product can be downloaded so watch for pipeline failures which contain the necessary URLs to follow.

You may also observe that on the first run, the export-installation job will fail because the Ops Manager is missing. Run this job manually once the install-opsman job has run successfully.

Teardown

The following steps will help you when you're ready to dispose of everything.

Use the om tool to delete the installation (be careful, you will not be asked to confirm this operation):

om delete-installation

Delete the Ops Manager VM:

gcloud compute instances delete "ops-manager-vm" --zone "${GCP_AZ1}" --quiet

Unwind the remaining PCF infrastructure:

cd ~/terraforming/terraforming-pcf
terraform destroy --auto-approve

Uninstall Concourse with control-tower:

GOOGLE_APPLICATION_CREDENTIALS=~/gcp_credentials.json \
  control-tower destroy \
    --region ${GCP_REGION} \
    --iaas gcp \
    ${PCF_SUBDOMAIN_NAME}

If you just want to destroy the current installation and "start clean" you can run this command that would teardown the entire PCF environment and reset the pipeline:

om delete-installation && gcloud compute instances delete ops-manager-vm --delete-disks all --zone ${GCP_REGION}-a --quiet && echo "---" > ~/state.yml && gsutil cp ~/state.yml gs://${PCF_SUBDOMAIN_NAME}-concourse-resources/ && fly -t control-tower-${PCF_SUBDOMAIN_NAME} destroy-pipeline -n -p pivotal-cloud-foundry && fly -t control-tower-${PCF_SUBDOMAIN_NAME} set-pipeline -p ${PRODUCT_SLUG} -n   -c ~/ops-manager-automation-cc/ci/${PRODUCT_SLUG}/pipeline.yml   -l ~/private.yml && fly -t control-tower-${PCF_SUBDOMAIN_NAME}  unpause-pipeline -p ${PRODUCT_SLUG}
