I am trying to create a terraform provider. And In resource Create method I want to convert the types.Object and []types.Object (from terraform-plugin-framework/types package) to usual Golang struct so I can make a post request to my api.
This is my struct and schema
type ClusterDetails struct {
ID types.String `tfsdk:"id"`
Name types.String `tfsdk:"name"`
CloudAccountID types.String `tfsdk:"cloud_account_id"`
CreatedAt types.String `tfsdk:"created_at"`
Status types.String `tfsdk:"status"`
Firewall []types.Object `tfsdk:"firewall"`
NodeGroups types.Object `tfsdk:"node_groups"`
}
func (r *clusterResource) Schema(_ context.Context, _ resource.SchemaRequest, resp *resource.SchemaResponse) {

This is what the responce for node_groups and firewall look like:
var (
NodesNodeGroupType = map[string]attr.Type{
"display_name": types.StringType,
"ip_address": types.StringType,
"is_active": types.BoolType,
}
NodeGroupTypes = map[string]attr.Type{
"region": types.StringType,
"cidr": types.StringType,
"availability_zones": types.ListType{
ElemType: types.StringType,
},
"public_subnets": types.ListType{
ElemType: types.StringType,
},
"private_subnets": types.ListType{
ElemType: types.StringType,
},
"nodes": types.ListType{
ElemType: types.ObjectType{
AttrTypes: NodesNodeGroupType,
},
},
"node_location": types.StringType,
"volume_size": types.Int64Type,
"volume_iops": types.Int64Type,
"volume_type": types.StringType,
"instance_type": types.StringType,
}
NodeGroupsTypes = map[string]attr.Type{
"aws": types.ListType{
ElemType: types.ObjectType{
AttrTypes: NodeGroupTypes,
},
},
"azure": types.ListType{
ElemType: types.ObjectType{
AttrTypes: NodeGroupTypes,
},
},
"google": types.ListType{
ElemType: types.ObjectType{
AttrTypes: NodeGroupTypes,
},
},
}
firewallElementsType := map[string]attr.Type{
"type": types.StringType,
"port": types.Float64Type,
"sources": types.ListType{
ElemType: types.StringType,
},
}
)
Now I need to use this node_groups and firewall in my api request in resources but I cant find a way to decrypt the values to Go's struct type. Heres what my structs and create method looks like:
type ClusterCreationRequestNodeGroups struct {
// aws
Aws []*NodeGroup `json:"aws"`
// azure
Azure []*NodeGroup `json:"azure"`
// google
Google []*NodeGroup `json:"google"`
}
type NodeGroup struct {
// availability zones
AvailabilityZones []string `json:"availability_zones"`
// cidr
Cidr string `json:"cidr,omitempty"`
// instance type
InstanceType string `json:"instance_type,omitempty"`
// node location
NodeLocation string `json:"node_location,omitempty"`
// nodes
Nodes []*NodeGroupNodesItems0 `json:"nodes"`
// private subnets
PrivateSubnets []string `json:"private_subnets"`
// public subnets
PublicSubnets []string `json:"public_subnets"`
// region
Region string `json:"region,omitempty"`
// volume iops
VolumeIops int64 `json:"volume_iops,omitempty"`
// volume size
VolumeSize int64 `json:"volume_size,omitempty"`
// volume type
VolumeType string `json:"volume_type,omitempty"`
}
type NodeGroupNodesItems0 struct {
// display name
DisplayName string `json:"display_name,omitempty"`
// ip address
IPAddress string `json:"ip_address,omitempty"`
// is active
IsActive bool `json:"is_active,omitempty"`
}
type ClusterCreationRequestFirewallRulesItems0 struct {
// port
Port int64 `json:"port,omitempty"`
// sources
Sources []string `json:"sources"`
// type
Type string `json:"type,omitempty"`
}
type ClusterCreationRequestFirewallRulesItems struct {
// port
Port int64 `json:"port,omitempty"`
// sources
Sources []string `json:"sources"`
// type
Type string `json:"type,omitempty"`
}
func (r *clusterResource) Create(ctx context.Context, req resource.CreateRequest, resp *resource.CreateResponse) {
