Creating AppContext
The following example shows how to create an AppContext for a CompositeApp with one App.

| ||||
func createAppContextWithOneApp(appName string)
{
context := appcontext.AppContext{}
ctxVal, err := context.InitAppContext()
if err != nil {
return nil
}
handle, err := context.CreateCompositeApp()
if err != nil {
return nil
}
appHandle, err := context.AddApp(handle, appName)
if err != nil {
return nil
}
// Iterate through cluster list and add all the clusters
for _, cluster := range clusterList {
clusterName := strings.Join([]string{cluster.ClusterProvider, "+", cluster.ClusterName}, "")
clusterHandle, err := context.AddCluster(appHandle, clusterName)
if err != nil {
return nil
}
// Add resource
_, err = context.AddResource(clusterHandle, nameofRes1, resYaml1)
if err != nil {
return nil
}
// Add resource
_, err = context.AddResource(clusterHandle, nameofRes2, resYaml2)
if err != nil {
return nil
}
// Add Resource Order
resOrder, err := json.Marshal(map[string][]string{"resorder": []string{nameofRes1, nameofRes2}})
if err != nil {
return nil
}
_, err = context.AddInstruction(clusterHandle, "resource", "order", string(resOrder))
if err != nil {
return nil
}
}
