var AppMoveCommand = &cobra.Command{
Use: "move <domain> <server> [flags]",
Aliases: []string{"d"},
Short: "Moves an app to a different server",
Long: `Deploy an app.
This command supports chaos operations. Use "--chaos/-C" to deploy your recipe
checkout as-is. Recipe commit hashes are also supported as values for
"[version]". Please note, "upgrade"/"rollback" do not support chaos operations.`,
Example: ` # standard deployment
abra app deploy 1312.net
# chaos deployment
abra app deploy 1312.net --chaos
# deploy specific version
abra app deploy 1312.net 2.0.0+1.2.3
# deploy a specific git hash
abra app deploy 1312.net 886db76d`,
