|
||||
In general, the dev-build-and-up.sh workflow for Rackspace is the similar to GCE. The specific implementation is different due to the use of CoreOS, Rackspace Cloud Files and network design.
|
||||
|
||||
These scripts should be used to deploy development environments for Kubernetes. If your account leverages RackConnect or non-standard networking, these scripts will most likely not work without modification.
|
||||
|
||||
NOTE: The rackspace scripts do NOT rely on `saltstack`.
|
||||
|
||||
The current cluster design is inspired by:
|
||||
- [corekube](https://github.com/metral/corekube/)
|
||||
- [Angus Lees](https://github.com/anguslees/kube-openstack/)
|
||||
|
||||
## Prerequisites
|
||||
1. You need to have both `nova` and `swiftly` installed. It's recommended to use a python virtualenv to install these packages into.
|
||||
2. Make sure you have the appropriate environment variables set to interact with the OpenStack APIs. See [Rackspace Documentation](http://docs.rackspace.com/servers/api/v2/cs-gettingstarted/content/section_gs_install_nova.html) for more details.
|
||||
3. You can test this by running `nova list` to make sure you're authenticated successfully.
|
||||
|
||||
## Provider: Rackspace
|
||||
- To use Rackspace as the provider, set the KUBERNETES_PROVIDER ENV variable:
|
||||
`export KUBERNETES_PROVIDER=rackspace` and run the `hack/rackspace/dev-build-and-up.sh` script.
|
||||
`export KUBERNETES_PROVIDER=rackspace` and run the `bash hack/dev-build-and-up.sh` script.
|
||||
|
||||
## Release
|
||||
1. The kubernetes binaries will be built via the common build scripts in `release/`. There is a specific `release/rackspace` directory with scripts for the following steps:
|
||||
## Build
|
||||
1. The kubernetes binaries will be built via the common build scripts in `build/`.
|
||||
2. If you've set the ENV `KUBERNETES_PROVIDER=rackspace`, the scripts will upload `kubernetes-server-linux-amd64.tar.gz` to Cloud Files.
|
||||
2. A cloud files container will be created via the `swiftly` CLI and a temp URL will be enabled on the object.
|
||||
3. The built `master-release.tar.gz` will be uploaded to this container and the URL will be passed to master/minions nodes when booted.
|
||||
- NOTE: RELEASE tagging and launch scripts are not used currently.
|
||||
3. The built `kubernetes-server-linux-amd64.tar.gz` will be uploaded to this container and the URL will be passed to master/minions nodes when booted.
|
||||
|
||||
## Cluster
|
||||
1. There is a specific `cluster/rackspace` directory with the scripts for the following steps:
|
||||
2. A cloud network will be created and all instances will be attached to this network. We will connect the master API and minion kubelet service via this network.
|
||||
3. A SSH key will be created and uploaded if needed. This key must be used to ssh into the machines since we won't capture the password.
|
||||
4. A master will be created via the `nova` CLI. A `cloud-config.yaml` is generated and provided as user-data. A basic `masterStart.sh` will be injected as a file and cloud-init will run it.
|
||||
5. We sleep for 25 seconds since we need to make sure we can get the IP address of the master on the cloud network we've created to provide the minions as their salt master.
|
||||
6. We then boot as many minions as defined via `$RAX_NUM_MINIONS`. We pass both a `cloud-config.yaml` as well as a `minionStart.sh`. The latter is executed via cloud-init just like on the master.
|
||||
4. A master and minions will be created via the `nova` CLI. A `cloud-config.yaml` is generated and provided as user-data with the entire configuration for the systems.
|
||||
5. We then boot as many minions as defined via `$RAX_NUM_MINIONS`.
|
||||
|
||||
## Some notes:
|
||||
- The scripts expect `eth2` to be the cloud network that the containers will communicate across.
|
||||
- `vxlan` is required on the cloud network interface since cloud networks will filter based on MAC address. This is the workaround for the time being.
|
||||
- A linux image with a recent kernel `> 13.07` is required for `vxlan`. Ubuntu 14.04 works.
|
||||
- A number of the items in `config-default.sh` are overridable via environment variables.
|
||||
- routes must be configured on each minion so that containers and kube-proxy are able to locate containers on another system. This is due to the network design in kubernetes and the MAC address limits on Cloud Networks. Static Routes are currently leveraged until we implement a more advanced solution.
|
||||
- For older versions please either:
|
||||
* Sync back to `v0.3` with `git checkout v0.3`
|
||||
* Download a [snapshot of `v0.3`](https://github.com/GoogleCloudPlatform/kubernetes/archive/v0.3.tar.gz)
|
||||
|
||||
## Network Design
|
||||
- eth0 - Public Interface used for servers/containers to reach the internet
|
||||
- eth1 - ServiceNet - Intra-cluster communication (k8s, etcd, etc) communicate via this interface. The `cloud-config` files use the special CoreOS identifier `$private_ipv4` to configure the services.
|
||||
- eth2 - Cloud Network - Used for k8s pods to communicate with one another. The proxy service will pass traffic via this interface.
