# Bootstrapping Deployment Manager
|
||||
|
||||
Welcome to the bootstrap example. The instructions below will step you through
|
||||
the process of building and running a local instance of Deployment Manager on
|
||||
your local machine, and then using it to deploy another instance in your cluster.
|
||||
|
||||
This example provides insights into how Deployment Manager works, and is
|
||||
recommended for anyone interested in contributing to the project.
|
||||
|
||||
The instructions below assume that you have a Kubernetes cluster up and running,
|
||||
and that you can run `kubectl` commands against it. They also assume that that
|
||||
you're working with a clone of the repository installed in the src folder of your
|
||||
GOPATH and that your PATH contains `$GOPATH/bin`, per convention.
|
||||
|
||||
## Installing required python packages
|
||||
|
||||
Since Deployment Manager uses Python and will be running locally on your
|
||||
machine, you will first need to make sure the necessary Python packages are
|
||||
installed. This assumes that you have already installed the pip package
|
||||
management system on your machine.
|
||||
|
||||
```
|
||||
sudo pip install -r expandybird/requirements.txt
|
||||
```
|
||||
|
||||
## Building and installing the binaries
|
||||
|
||||
Next, you're going to build and install the Deployment Manager binaries. You can
|
||||
do this by running make in the repository root.
|
||||
|
||||
```
|
||||
make
|
||||
```
|
||||
|
||||
## Bootstrapping Deployment Manager
|
||||
|
||||
Now, you're ready to bootstrap Deployment Manager into the cluster.
|
||||
|
||||
### Start Deployment Manager on localhost
|
||||
|
||||
First, start the three Deployment Manager binaries on localhost using the supplied
|
||||
bootstrap script.
|
||||
|
||||
```
|
||||
./examples/bootstrap/bootstrap.sh
|
||||
```
|
||||
|
||||
The script starts the following binaries:
|
||||
* manager (frontend service) running on port 8080
|
||||
* expandybird (expands templates) running on port 8081
|
||||
* resourcifier (reifies primitive Kubernetes resources) running on port 8082
|
||||
|
||||
It also starts kubectl proxy on port 8001.
|
||||
|
||||
### Deploy Deployment Manager into your cluster
|
||||
|
||||
Next, use the Deployment Manager running on localhost to deploy itself onto the
|
||||
cluster using the supplied command line tool and template.
|
||||
|
||||
```
|
||||
client --name test --service=http://localhost:8080 examples/bootstrap/bootstrap.yaml
|
||||
```
|
||||
|
||||
You should now have Deployment Manager running on your cluster, and it should be
|
||||
visible using kubectl (kubectl get pod,rc,service).
