/*
Package nodegroups provides methods for interacting with the Magnum node group API.
All node group actions must be performed on a specific cluster,
so the cluster UUID/name is required as a parameter in each method.
Create a client to use:
opts, err := openstack.AuthOptionsFromEnv()
if err != nil {
panic(err)
}
provider, err := openstack.AuthenticatedClient(opts)
if err != nil {
panic(err)
}
client, err := openstack.NewContainerInfraV1(provider, gophercloud.EndpointOpts{Region: os.Getenv("OS_REGION_NAME")})
if err != nil {
panic(err)
}
client.Microversion = "1.9"
Example of Getting a node group:
ng, err := nodegroups.Get(client, clusterUUID, nodeGroupUUID).Extract()
if err != nil {
panic(err)
}
fmt.Printf("%#v\n", ng)
Example of Listing node groups:
listOpts := nodegroup.ListOpts{
Role: "worker",
}
allPages, err := nodegroups.List(client, clusterUUID, listOpts).AllPages()
if err != nil {
panic(err)
}
ngs, err := nodegroups.ExtractNodeGroups(allPages)
if err != nil {
panic(err)
}
for _, ng := range ngs {
fmt.Printf("%#v\n", ng)
}
Example of Creating a node group:
// Labels, node image and node flavor will be inherited from the cluster value if not set.
// Role will default to "worker" if not set.
// To add a label to the new node group, need to know the cluster labels
cluster, err := clusters.Get(client, clusterUUID).Extract()
if err != nil {
panic(err)
}
// Add the new label
labels := cluster.Labels
labels["availability_zone"] = "A"
maxNodes := 5
createOpts := nodegroups.CreateOpts{
Name: "new-nodegroup",
MinNodeCount: 2,
MaxNodeCount: &maxNodes,
Labels: labels,
}
ng, err := nodegroups.Create(client, clusterUUID, createOpts).Extract()
if err != nil {
panic(err)
}
fmt.Printf("%#v\n", ng)
Example of Updating a node group:
// Valid paths are "/min_node_count" and "/max_node_count".
// Max node count can be unset with the "remove" op to have
// no enforced maximum node count.
updateOpts := []nodegroups.UpdateOptsBuilder{
nodegroups.UpdateOpts{
Op: nodegroups.ReplaceOp,
Path: "/max_node_count",
Value: 10,
},
}
ng, err = nodegroups.Update(client, clusterUUID, nodeGroupUUID, updateOpts).Extract()
if err != nil {
panic(err)
}
fmt.Printf("%#v\n", ng)
Example of Deleting a node group:
err = nodegroups.Delete(client, clusterUUID, nodeGroupUUID).ExtractErr()
if err != nil {
panic(err)
}
