This is a prototype of kubernetes deployment on vCenter.

• 1 vCenter.
• 1 ESX.
• 1 datastore with at least 40GB of space.

Currently the prototype has been tested by running the service in eclipse only.

• Install ISO generation utility genisoimage or mkisofs.
• Download and install JDK 8 (latest patch).
• Download and install latest version of gradle from https://gradle.org/gradle-download/.
• Install latest version of Eclipse IDE.
• Install gradle eclipse plugin (buildship) in eclipse.

• Clone this repo and go to java directory> cd [project-dir]/vcs-proto1/java
• Build the project by executing command> gradle build
• Once the project has built successfully import [project-dir]/vcs-proto1/java as gradle project in eclipse. The parent gradle project (build.gradle file) is in vcs-proto1/java directory.

• Edit java/common/src/main/resources/vcs.properties file as per your dev environment setup.
• Edit java/vsphere-client/src/main/resources/vsphere-client.properties to point to your vCenter setup.
  • One of the working kubernetes image is available here http://pa-dbc1131.eng.vmware.com/prashimas/misc/images/kubernetes/, currently accessible from within VMware network (will fix this soon!).

• The main class for this service is com.vmware.vcs.core.Main. Run this as Java application with the following program and VM arguments.
  • Under program arguments specify “java/common/src/main/resources/vcs.properties” file as an argument.
  • Under VM arguments specify “-Dvsphere-client-properties=vsphere-client.properties –Dssl.trustAll.enabled=true”

Users will need REST API client to interacte with this service.

• GET http://127.0.0.1:19000/

  • Lists various services running within this service. Most of which are not of any use at this point. Except for the ones listed below.

• GET http://127.0.0.1:19000/vcs/cloudstore/clusters

  • Lists all clusters created with this service.

• DELETE http://127.0.0.1:19000/vcs/cloudstore/clusters/

  • Deletes the cluster.

• POST http://127.0.0.1:19000/vcs/clustermanager/vcs-cluster-create

  • Creates a kubernestes cluster as per the passed arguments passed and set in the properties files.
  • Sample Body

 { "clusterState" : "CREATING",
   "clusterName" : "cluster1", 
   "clusterType" : "KUBERNETES", 
   "imageId" : "Kubernetes-image.vmdk", 
   "projectId" : "k8s-project", 
   "vmNetworkId" : "VM Network", 
   "diskFlavorName" : "Disk flavor", 
   "masterVmFlavorName" : "Master flavor", 
   "otherVmFlavorName" : "Slave Flavor", 
   "slaveCount" : "1", 
   "extendedProperties" : { 
      "etcd_ips" : "10.20.104.90", 
      "dns" : "10.20.145.1", 
      "gateway" : "10.20.107.253", 
      "netmask" : "255.255.252.0", 
      "master_ip" : "10.20.104.92", 
      "container_network" : "10.20.0.1/20" 
     } 
  }

• Modify clusterName, etcd_ips, dns, gateway, netmask, master_ip to appropriate values as per your setup.

• There will be a parent image VM and snapshot created in vCenter. Do not delete the VM and snapshot.
• First cluster creation might take some time due to image upload.
