For example, if you want to create a new project as\npart of a deployment, you need to ensure that the project is created before you\nadd any resources to it.\n\nYou can specify these dependencies using the `dependsOn` option in your configuration\nfiles or templates. When you add the `dependsOn` option for a resource, Deployment\nManager creates or updates the dependencies before creating or updating\nthe resource.\n\nYou can create dependencies between base types that are part of your deployment,\neither in the configuration file, or in the templates that you use for the deployment.\nYou cannot set a dependency on template files or composite types.\n\nFor background information on base and composite types, see the\n[Types Overview](/deployment-manager/docs/fundamentals#types).\n\nBefore you begin\n----------------\n\n- If you want to use the command-line examples in this guide, install the [\\`gcloud\\` command-line tool](/sdk).\n- If you want to use the API examples in this guide, set up [API access](/deployment-manager/docs/reference/latest).\n\nCreating dependencies\n---------------------\n\nTo add a dependency to a resource, add a `metadata` section that contains a\n`dependsOn` section. Then, in the `dependsOn` section, specify one or more\ndependencies.\n\nIn the following example, to make `a-special-vm` dependent on the creation of two\npersistent disks, add the `metadata` and `dependsOn` sections for `a-special-vm`.\nThen, add the dependencies for each persistent disk.\n\nIn the same deployment, you must define the persistent disks that are dependencies.\nIn this example, the disks are `persistent-disk-a` and `persistent-disk-b`: \n\n resources:\n - name: a-special-vm\n type: compute.v1.instances\n properties:\n ...\n\n metadata:\n dependsOn:\n - persistent-disk-a\n - persistent-disk-b\n\n - name: persistent-disk-a\n type: compute.v1.disks\n properties:\n ...\n\n - name: persistent-disk-b\n type: compute.v1.disks\n properties:\n ...\n\nIn this deployment, Deployment Manager creates `persistent-disk-a` and\n`persistent-disk-b` before creating `a-special-vm`.\n| **Warning:** Avoid creating dependency loops. For example, if you specify that resource A depends on resource B, and resource B depends on resource A, a dependency loop is created, and the deployment fails. Additionally, if you use [references](/deployment-manager/docs/configuration/use-references) in your deployment, implicit dependencies are created, which might also cause dependency loops.\n\nWhat's next\n-----------\n\n- [Create a deployment](/deployment-manager/docs/deployments).\n- Learn about [references](/deployment-manager/docs/configuration/use-references).\n- Learn more about [templates](/deployment-manager/docs/configuration/templates/create-basic-template)."]]
