Updated for bosh-warden-cpi v28+.
This topic describes cloud properties for different resources created by the Warden/Garden CPI.
Currently the CPI does not support any cloud properties for AZs.
azs: - name: z1
Currently the CPI does not support any cloud properties for networks.
Example of a manual network:
networks: - name: default type: manual subnets: - range: 10.244.1.0/24 gateway: 10.244.1.0 static: [10.244.1.34]
bosh-warden-cpi v24+ makes it possible to use subnets bigger than /30 as exemplified above. bosh-lite v9000.48.0 uses that newer bosh-warden-cpi.
Example of a dynamic network:
networks: - name: default type: dynamic
The CPI does not support vip networks.
Resource Pools / VM Types¶
- ports [Array, optional]: Allows to define port mapping between host and associated containers. Available in v30+.
- host [String, required]: Port or range of ports. Example:
- container [String, optional]: Port or range of ports. Defaults to
hostdefined port or range. Example:
- protocol [String, optional]: Connection protocol. Defaults to
We may add simple load balancing via iptables for testing if ports is forwarded to multiple containers.
vm_extensions: - name: external-access cloud_properties: ports: # Forward 80 to 80 tcp - host: 80 # Forward 443 to 8443 tcp - host: 443 container: 8443 # Forward 53 to 53 udp - host: 53 protocol: udp # Forward 1000-2000 to 1000-2000 tcp - host: 1000-2000
Currently the CPI does not support any cloud properties for disks.
Example of 10GB disk:
disk_pools: - name: default disk_size: 10_240
The CPI uses containers to represent VMs and loopback devices to represent disks. Since the CPI can only talk to a single Garden server it can only manage resources on a single machine.
Example of a CPI configuration:
properties: warden_cpi: loopback_range: [100, 130] warden: connect_network: tcp connect_address: 127.0.0.1:7777 actions: stemcells_dir: "/var/vcap/data/cpi/stemcells" disks_dir: "/var/vcap/store/cpi/disks" host_ephemeral_bind_mounts_dir: "/var/vcap/data/cpi/ephemeral_bind_mounts_dir" host_persistent_bind_mounts_dir: "/var/vcap/data/cpi/persistent_bind_mounts_dir" agent: mbus: nats://nats:((nats_password))@10.244.8.2:4222 blobstore: provider: dav options: endpoint: http://10.244.8.2:25251 user: agent password: ((blobstore_agent_password))
Example Cloud Config¶
- Garden server does not have a UI; however, you can use gaol CLI to interact with it directly.
