»BSU Volume Builder

Type: osc-bsuvolume Artifact BuilderId: oapi.outscale.bsuvolume

The osc-bsuvolume Packer builder is able to create Ouscale Block Stogate Unit volumes which are prepopulated with filesystems or data.

This builder builds BSU volumes by launching an Outscale VM from a source OMI, provisioning that running machine, and then destroying the source machine, keeping the volumes intact.

This is all done in your own Outscale account. The builder will create temporary key pairs, security group rules, etc. that provide it temporary access to the instance while the image is being created.

The builder does not manage BSU Volumes. Once it creates volumes and stores it in your account, it is up to you to use, delete, etc. the volumes.

»Configuration Reference

There are many configuration options available for the builder. They are segmented below into two categories: required and optional parameters. Within each category, the available configuration keys are alphabetized.

In addition to the options listed here, a communicator can be configured for this builder.


  • access_key (string) - The access key used to communicate with OUTSCALE. Learn how to set this

  • vm_type (string) - The Outscale VM type to use while building the OMI, such as t2.small.

  • region (string) - The name of the region, such as us-east-1, in which to launch the Outscale VM to create the OMI.

  • secret_key (string) - The secret key used to communicate with Outscale. Learn how to set this

  • source_omi (string) - The initial OMI used as a base for the newly created machine. source_omi_filter may be used instead to populate this automatically.


  • ebs_volumes (array of block device mappings) - Add the block device mappings to the OMI. The block device mappings allow for keys:

    • device_name (string) - The device name exposed to the VM (for example, /dev/sdh or xvdh). Required for every device in the block device mapping.

    • delete_on_vm_deletion (boolean) - Indicates whether the BSU volume is deleted on instance termination.

    • iops (number) - The number of I/O operations per second (IOPS) that the volume supports. See the documentation on IOPs for more information.

    • no_device (boolean) - Suppresses the specified device included in the block device mapping of the OMI.

    • snapshot_id (string) - The ID of the snapshot

    • virtual_name (string) - The virtual device name. See the documentation on Block Device Mapping for more information

    • volume_size (number) - The size of the volume, in GiB. Required if not specifying a snapshot_id

    • volume_type (string) - The volume type. gp2 for General Purpose (SSD) volumes, io1 for Provisioned IOPS (SSD) volumes, and standard for Magnetic volumes

    • tags (map) - Tags to apply to the volume. These are retained after the builder completes. This is a template engine, see Build template data for more information.

  • associate_public_ip_address (boolean) - If using a non-default Net, public IP addresses are not provided by default. If this is toggled, your new VM will get a Public IP.

  • subregion_name (string) - Destination subregion to launch VM in. Leave this empty to allow Outscale to auto-assign.

  • custom_endpoint_oapi (string) - This option is useful if you use a cloud provider whose API is compatible with Outscale OAPI. Specify another endpoint like this

  • disable_stop_vm (boolean) - Packer normally stops the build VM after all provisioners have run. For Windows VMs, it is sometimes desirable to run Sysprep which will stop the VM for you. If this is set to true, Packer will not stop the VM but will assume that you will send the stop signal yourself through your final provisioner. You can do this with a windows-shell provisioner.

    Note that Packer will still wait for the VM to be stopped, and failing to send the stop signal yourself, when you have set this flag to true, will cause a timeout.

  • bsu_optimized (boolean) - If true, the VM is created with optimized BSU I/O.

  • insecure_skip_tls_verify (boolean) - This allows skipping TLS verification of the OAPI endpoint. The default is false.

  • run_tags (object of key/value strings) - Tags to apply to the instance that is launched to create the OMI. These tags are not applied to the resulting OMI unless they're duplicated in tags. This is a template engine, see Build template data for more information.

  • security_group_id (string) - The ID (not the name) of the security group to assign to the VM. By default this is not set and Packer will automatically create a new temporary security group to allow SSH access. Note that if this is specified, you must be sure the security group allows access to the ssh_port given below.

  • security_group_ids (array of strings) - A list of security groups as described above. Note that if this is specified, you must omit the security_group_id.

  • shutdown_behavior (string) - Automatically terminate instances on shutdown in case Packer exits ungracefully. Possible values are stop and terminate. Defaults to stop.

  • shutdown_behavior (string) - Automatically terminate VMs on shutdown in case Packer exits ungracefully. Possible values are "stop" and "terminate", default is stop.

  • snapshot_groups (array of strings) - A list of groups that have access to create volumes from the snapshot(s). By default no groups have permission to create volumes from the snapshot(s). all will make the snapshot publicly accessible.

  • snapshot_users (array of strings) - A list of account IDs that have access to create volumes from the snapshot(s). By default no additional users other than the user creating the OMIS has permissions to create volumes from the backing snapshot(s).

  • source_omi_filter (object) - Filters used to populate the source_omi field.

    • filters (map of strings) - filters used to select a source_omi.

    • owners (array of strings) - Filters the images by their owner. You may specify one or more Outscale account IDs, "self" (which will use the account whose credentials you are using to run Packer), or an Outscale owner alias. This option is required for security reasons.


        "source_omi_filter": {
          "filters": {
            "virtualization-type": "hvm",
            "image-name": "ubuntu/images/*ubuntu-xenial-16.04-amd64-server-*",
            "root-device-type": "ebs"
          "owners": ["099720109477"]
      {  "source_omi_filter": {    "filters": {      "virtualization-type": "hvm",      "image-name": "ubuntu/images/*ubuntu-xenial-16.04-amd64-server-*",      "root-device-type": "ebs"    },    "owners": ["099720109477"]  }}

      This selects an Ubuntu 16.04 HVM BSU OMIS from Canonical. NOTE: This will fail unless exactly one OMIS is returned. In the above example, most_recent will cause this to succeed by selecting the newest image.

  • ssh_keypair_name (string) - If specified, this is the key that will be used for SSH with the machine. The key must match a key pair name loaded up into Outscale. By default, this is blank, and Packer will generate a temporary keypair unless ssh_password is used. ssh_private_key_file or ssh_agent_auth must be specified when ssh_keypair_name is utilized.

  • ssh_interface (string) - One of public_ip, private_ip, public_dns, or private_dns. If set, either the public IP address, private IP address, public DNS name or private DNS name will used as the host for SSH. The default behaviour if inside a Net is to use the public IP address if available, otherwise the private IP address will be used. If not in a Net the public DNS name will be used. Also works for WinRM.

    Where Packer is configured for an outbound proxy but WinRM traffic should be direct, ssh_interface must be set to private_dns and <region>.compute.internal included in the NO_PROXY environment variable.

  • subnet_id (string) - If using Net, the ID of the subnet, such as subnet-12345def, where Packer will launch the VM. This field is required if you are using an non-default Net.

  • temporary_key_pair_name (string) - The name of the temporary key pair to generate. By default, Packer generates a name that looks like packer_<UUID>, where <UUID> is a 36 character unique identifier.

  • temporary_security_group_source_cidr (string) - An IPv4 CIDR block to be authorized access to the VM, when packer is creating a temporary security group. The default is (i.e., allow any IPv4 source). This is only used when security_group_id or security_group_ids is not specified.

  • user_data (string) - User data to apply when launching the VM. Note that you need to be careful about escaping characters due to the templates being JSON. It is often more convenient to use user_data_file, instead. Packer will not automatically wait for a user script to finish before shutting down the VM this must be handled in a provisioner.

  • user_data_file (string) - Path to a file that will be used for the user data when launching the VM.

  • net_id (string) - If launching into a Net subnet, Packer needs the Net ID in order to create a temporary security group within the Net. Requires subnet_id to be set. If this field is left blank, Packer will try to get the Net ID from the subnet_id.

  • net_filter (object) - Filters used to populate the net_id field. Example:

      "net_filter": {
        "filters": {
          "is-default": "false",
          "ip-range": "/24"
    {  "net_filter": {    "filters": {      "is-default": "false",      "ip-range": "/24"    }  }}

    This selects the Net with a IPv4 CIDR block of /24. NOTE: This will fail unless exactly one Net is returned.

    • filters (map of strings) - filters used to select a vpc_id. NOTE: This will fail unless exactly one Net is returned.

      net_id take precedence over this.

  • windows_password_timeout (string) - The timeout for waiting for a Windows password for Windows VMs. Defaults to 20 minutes. Example value: 10m

Further information on locating OMI's IDs and their relationship to VM types and regions can be found in the Outscale Documentation reference.

»Accessing the Instance to Debug

If you need to access the instance to debug for some reason, run the builder with the -debug flag. In debug mode, the Amazon builder will save the private key in the current directory and will output the DNS or IP information as well. You can use this information to access the instance as it is running.

»Build template data

In configuration directives marked as a template engine above, the following variables are available:

  • BuildRegion - The region (for example eu-west-2) where Packer is building the OMI.
  • SourceOMI - The source OMI ID (for example ami-a2412fcd) used to build the OMI.
  • SourceOMIName - The source OMI Name (for example ubuntu/images/ebs-ssd/ubuntu-xenial-16.04-amd64-server-20180306) used to build the OMI.
  • SourceOMITags - The source OMI Tags, as a map[string]string object.
