  • LOCAL_BASIC: 50
  • Other: 50 ~ 1000 (need whitelist if > 50)

• data_disks (array of data disks) - Add one or more data disks to the instance before creating the image. Note that if the source image has data disk snapshots, this argument will be ignored, and the running instance will use source image data disk settings, in such case, disk_type argument will be used as disk type for all data disks, and each data disk size will use the origin value in source image. The data disks allow for the following argument:

  • disk_type - Type of the data disk. Valid choices: CLOUD_BASIC, CLOUD_PREMIUM and CLOUD_SSD.

Communicator Configuration

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

Optional:

• communicator (string) - Packer currently supports three kinds of communicators:

  • none - No communicator will be used. If this is set, most provisioners also can't be used.

  • ssh - An SSH connection will be established to the machine. This is usually the default.

  • winrm - A WinRM connection will be established.

  In addition to the above, some builders have custom communicators they can use. For example, the Docker builder has a "docker" communicator that uses docker exec and docker cp to execute scripts and copy files.

• pause_before_connecting (duration string | ex: "1h5m2s") - We recommend that you enable SSH or WinRM as the very last step in your guest's bootstrap script, but sometimes you may have a race condition where you need Packer to wait before attempting to connect to your guest.

  If you end up in this situation, you can use the template option pause_before_connecting. By default, there is no pause. For example if you set pause_before_connecting to 10m Packer will check whether it can connect, as normal. But once a connection attempt is successful, it will disconnect and then wait 10 minutes before connecting to the guest and beginning provisioning.

• ssh_host (string) - The address to SSH to. This usually is automatically configured by the builder.

• ssh_port (int) - The port to connect to SSH. This defaults to 22.

• ssh_username (string) - The username to connect to SSH with. Required if using SSH.

• ssh_password (string) - A plaintext password to use to authenticate with SSH.

• ssh_ciphers ([]string) - This overrides the value of ciphers supported by default by Golang. The default value is [ "aes128-gcm@openssh.com", "chacha20-poly1305@openssh.com", "aes128-ctr", "aes192-ctr", "aes256-ctr", ]

  Valid options for ciphers include: "aes128-ctr", "aes192-ctr", "aes256-ctr", "aes128-gcm@openssh.com", "chacha20-poly1305@openssh.com", "arcfour256", "arcfour128", "arcfour", "aes128-cbc", "3des-cbc",

• ssh_clear_authorized_keys (bool) - If true, Packer will attempt to remove its temporary key from ~/.ssh/authorized_keys and /root/.ssh/authorized_keys. This is a mostly cosmetic option, since Packer will delete the temporary private key from the host system regardless of whether this is set to true (unless the user has set the -debug flag). Defaults to "false"; currently only works on guests with sed installed.

• ssh_key_exchange_algorithms ([]string) - If set, Packer will override the value of key exchange (kex) algorithms supported by default by Golang. Acceptable values include: "curve25519-sha256@libssh.org", "ecdh-sha2-nistp256", "ecdh-sha2-nistp384", "ecdh-sha2-nistp521", "diffie-hellman-group14-sha1", and "diffie-hellman-group1-sha1".

• ssh_certificate_file (string) - Path to user certificate used to authenticate with SSH. The ~ can be used in path and will be expanded to the home directory of current user.

• ssh_pty (bool) - If true, a PTY will be requested for the SSH connection. This defaults to false.

• ssh_timeout (duration string | ex: "1h5m2s") - The time to wait for SSH to become available. Packer uses this to determine when the machine has booted so this is usually quite long. Example value: 10m. This defaults to 5m, unless ssh_handshake_attempts is set.

• ssh_disable_agent_forwarding (bool) - If true, SSH agent forwarding will be disabled. Defaults to false.

• ssh_handshake_attempts (int) - The number of handshakes to attempt with SSH once it can connect. This defaults to 10, unless a ssh_timeout is set.

• ssh_bastion_host (string) - A bastion host to use for the actual SSH connection.

• ssh_bastion_port (int) - The port of the bastion host. Defaults to 22.

• ssh_bastion_agent_auth (bool) - If true, the local SSH agent will be used to authenticate with the bastion host. Defaults to false.

• ssh_bastion_username (string) - The username to connect to the bastion host.

• ssh_bastion_password (string) - The password to use to authenticate with the bastion host.

• ssh_bastion_interactive (bool) - If true, the keyboard-interactive used to authenticate with bastion host.

• ssh_bastion_private_key_file (string) - Path to a PEM encoded private key file to use to authenticate with the bastion host. The ~ can be used in path and will be expanded to the home directory of current user.

• ssh_bastion_certificate_file (string) - Path to user certificate used to authenticate with bastion host. The ~ can be used in path and will be expanded to the home directory of current user.

• ssh_file_transfer_method (string) - scp or sftp - How to transfer files, Secure copy (default) or SSH File Transfer Protocol.

  NOTE: Guests using Windows with Win32-OpenSSH v9.1.0.0p1-Beta, scp (the default protocol for copying data) returns a a non-zero error code since the MOTW cannot be set, which cause any file transfer to fail. As a workaround you can override the transfer protocol with SFTP instead ssh_file_transfer_protocol = "sftp".

• ssh_proxy_host (string) - A SOCKS proxy host to use for SSH connection

• ssh_proxy_port (int) - A port of the SOCKS proxy. Defaults to 1080.

• ssh_proxy_username (string) - The optional username to authenticate with the proxy server.

• ssh_proxy_password (string) - The optional password to use to authenticate with the proxy server.

• ssh_keep_alive_interval (duration string | ex: "1h5m2s") - How often to send "keep alive" messages to the server. Set to a negative value (-1s) to disable. Example value: 10s. Defaults to 5s.

• ssh_read_write_timeout (duration string | ex: "1h5m2s") - The amount of time to wait for a remote command to end. This might be useful if, for example, packer hangs on a connection after a reboot. Example: 5m. Disabled by default.

• ssh_remote_tunnels ([]string) -

• ssh_local_tunnels ([]string) -

• temporary_key_pair_type (string) - dsa | ecdsa | ed25519 | rsa ( the default )

  Specifies the type of key to create. The possible values are 'dsa', 'ecdsa', 'ed25519', or 'rsa'.

  NOTE: DSA is deprecated and no longer recognized as secure, please consider other alternatives like RSA or ED25519.

• temporary_key_pair_bits (int) - Specifies the number of bits in the key to create. For RSA keys, the minimum size is 1024 bits and the default is 4096 bits. Generally, 3072 bits is considered sufficient. DSA keys must be exactly 1024 bits as specified by FIPS 186-2. For ECDSA keys, bits determines the key length by selecting from one of three elliptic curve sizes: 256, 384 or 521 bits. Attempting to use bit lengths other than these three values for ECDSA keys will fail. Ed25519 keys have a fixed length and bits will be ignored.

  NOTE: DSA is deprecated and no longer recognized as secure as specified by FIPS 186-5, please consider other alternatives like RSA or ED25519.

• 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 the remote. 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_private_key_file (string) - Path to a PEM encoded private key file to use to authenticate with SSH. The ~ can be used in path and will be expanded to the home directory of current user.

• ssh_agent_auth (bool) - If true, the local SSH agent will be used to authenticate connections to the source instance. No temporary keypair will be created, and the values of ssh_password and ssh_private_key_file will be ignored. The environment variable SSH_AUTH_SOCK must be set for this option to work properly.
