## Getting started locally
|
|
|
|
### Requirements
|
|
|
|
#### Linux
|
|
|
|
Not running Linux? Consider running Linux in a local virtual machine with [Vagrant](vagrant.md), or on a cloud provider like [Google Compute Engine](gce.md)
|
|
|
|
#### Docker
|
|
|
|
At least [Docker](https://docs.docker.com/installation/#installation) 1.0.0+. Ensure the Docker daemon is running and can be contacted by the user you plan to run as (try `docker ps`).
|
|
|
|
#### etcd
|
|
|
|
You need an [etcd](https://github.com/coreos/etcd) somewhere in your path. Get the [latest release](https://github.com/coreos/etcd/releases/) and place it in `/usr/bin`.
|
|
|
|
|
|
### Starting the cluster
|
|
|
|
In a separate tab of your terminal, run:
|
|
|
|
```
|
|
cd kubernetes
|
|
hack/local-up-cluster.sh
|
|
```
|
|
|
|
This will build and start a lightweight local cluster, consisting of a master and a single minion. Type Control-C to shut it down.
|
|
|
|
You can use the cluster/kubecfg.sh script to interact with the local cluster.
|
|
|
|
```
|
|
cd kubernetes
|
|
modify cluster/kube-env.sh:
|
|
KUBERNETES_PROVIDER="local"
|
|
|
|
cluster/kubecfg.sh => interact with the local cluster
|
|
```
|
|
|
|
### Running a container
|
|
|
|
Your cluster is running, and you want to start running containers!
|
|
|
|
You can now use any of the cluster/kubecfg.sh commands to interact with your local setup.
|
|
```
|
|
cluster/kubecfg.sh list /pods
|
|
cluster/kubecfg.sh list /services
|
|
cluster/kubecfg.sh list /replicationControllers
|
|
cluster/kubecfg.sh -p 8080:80 run dockerfile/nginx 1 myNginx
|
|
|
|
|
|
## begin wait for provision to complete, you can monitor the docker pull by opening a new terminal
|
|
sudo docker images
|
|
## you should see it pulling the dockerfile/nginx image, once the above command returns it
|
|
sudo docker ps
|
|
## you should see your container running!
|
|
exit
|
|
## end wait
|
|
|
|
## introspect kubernetes!
|
|
cluster/kubecfg.sh list /pods
|
|
cluster/kubecfg.sh list /services
|
|
cluster/kubecfg.sh list /replicationControllers
|
|
```
|
|
|
|
Congratulations!
|
|
|
|
### Troubleshooting
|
|
|
|
#### I cannot create a replication controller with replica size greater than 1! What gives?
|
|
|
|
You are running a single minion setup. This has the limitation of only supporting a single replica of a given pod. If you are interested in running with larger replica sizes, we encourage you to try the local vagrant setup or one of the cloud providers.
|
|
|
|
#### I changed Kubernetes code, how do I run it?
|
|
|
|
```
|
|
cd kubernetes
|
|
hack/build-go.sh
|
|
hack/local-up-cluster.sh
|
|
```
