## Deployment Guide
*Note that Shipyard is still under active development and this guide will evolve along the way*
The current deployment makes use of the [ucp-integration](https://github.com/att-comdev/ucp-integration)
repository to set up the underlaying Kubernetes infrastructure, Ceph and UCP components. This
approach sets up an 'All-In-One' UCP environment that allows developers to bring up Shipyard
and the rest of the UCP components on a single Ubuntu 16.04 Virtual Machine.
*Note that the minimum recommended size of the VM is 4 vCPUs, 16GB of RAM with 64GB disk space*
### Pre-Deployment Preparations
1) Set up `etc/hosts` on a freshly installed Ubuntu 16.04 Virtual Machine
```
HOST_IFACE=$(ip route | grep "^default" | head -1 | awk '{ print $5 }')
LOCAL_IP=$(ip addr | awk "/inet/ && /${HOST_IFACE}/{sub(/\/.*$/,\"\",\$2); print \$2}")
cat << EOF | sudo tee -a /etc/hosts
${LOCAL_IP} $(hostname)
EOF
```
2) Clone the [ucp-integration](https://github.com/att-comdev/ucp-integration) repository. Update
the hostname in the `deploy_ucp.sh` script
```
git clone https://github.com/att-comdev/ucp-integration.git
sed -i -e s/node1/$(hostname)/g /home/ubuntu/ucp-integration/manifests/basic_ucp/deploy_ucp.sh
```
### Production Deployment
We will use this approach if we are not making any changes to Shipyard and would like to bring up
the UCP environment as it is
1) Switch to root user after performing the steps in the *Pre-Deployment Preparations* section.
```
sudo -i
cd /home/ubuntu/ucp-integration/manifests/basic_ucp/
```
2) Export the variables that are unique to the environment. For instance, we can do the following
to update the environment variables for a VM that is assigned an IP of *30.30.30.4* on interface
*ens3* (network *30.30.30.0/24*):
```
export CEPH_CLUSTER_NET=30.30.30.0/24
export CEPH_PUBLIC_NET=30.30.30.0/24
export GENESIS_NODE_IP=30.30.30.4
export NODE_NET_IFACE=ens3
```
3) Start the UCP deployment
```
./deploy_ucp.sh
```
### Dev Environment Deployment
We will use this approach if we want to bring up a dev environment that allows us to test our own
dags and operators in Airflow. Changes to Shipyard API/CLI will require a rebuild of the Shipyard
images with the updates. We will need to reference to the custom image in our environment variables
so that it does not point to the image in the Master branch.
1) Create the following directories on the target host machine:
```
mkdir -p /home/ubuntu/workbench/dags
mkdir -p /home/ubuntu/workbench/plugins
mkdir -p /home/ubuntu/workbench/logs
```
2) Copy the [rest_api_plugin](https://github.com/att-comdev/shipyard/blob/master/shipyard_airflow/plugins/rest_api_plugin.py)
into the newly created plugins directory, i.e. `/home/ubuntu/workbench/plugins` so that it can
be loaded by Airflow during startup. Note that other custom operators can also be added to the
directory as required.
Note: Custom dags should be added into the newly created dags directory, i.e. `/home/ubuntu/workbench/dags`
3) Update `armada.yaml.sub` to override the settings for Shipyard
```
sed -i -e 's/prod_environment: true/prod_environment: false/g' /home/ubuntu/ucp-integration/manifests/basic_ucp/armada.yaml.sub
```
4) Switch to root user after performing Step 1 to 3
```
sudo -i
cd /home/ubuntu/ucp-integration/manifests/basic_ucp/
```
5) Export the variables that are unique to the environment. For instance, we can do the below
to update the environment variables for a VM that is assigned an IP of *30.30.30.4* on interface
*ens3* (network *30.30.30.0/24*).
Update image references in the environment variables if we want to test a new Shipyard and/or Airflow
image, e.g. image v0.1.0 as a result of code changes.
```
export CEPH_CLUSTER_NET=30.30.30.0/24
export CEPH_PUBLIC_NET=30.30.30.0/24
export GENESIS_NODE_IP=30.30.30.4
export NODE_NET_IFACE=ens3
export SHIPYARD_IMAGE="attcomdev/shipyard:v0.1.0"
export AIRFLOW_IMAGE="attcomdev/airflow:v0.1.0"
```
6) Start the UCP deployment
```
./deploy_ucp.sh
```
### Post Deployment
1) The deployment is fully automated and can take a while to complete (it can take 30 minutes to an
hour for a full deployment to complete)
2) The environment should resemble the following after executing the required steps:
```
# sudo kubectl get pods -n ucp
