The provisioner is designed to communicate with machines running WinRM. 16 17 ## Basic Example 18 19 The example below is fully functional. 20 21 <Tabs> 22 <Tab heading="HCL2"> 23 24 ```hcl 25 provisioner "windows-shell" { 26 inline = ["dir c:\\"] 27 } 28 ``` 29 30 </Tab> 31 <Tab heading="JSON"> 32 33 ```json 34 { 35 "type": "windows-shell", 36 "inline": ["dir c:\\"] 37 } 38 ``` 39 40 </Tab> 41 </Tabs> 42 43 ## Configuration Reference 44 45 @include 'provisioners/shell-config.mdx' 46 47 - `env` (map of strings) - A map of key/value pairs to inject prior to the 48 execute_command. Packer injects some environmental variables by default into 49 the environment, as well, which are covered in the section below. Duplicate 50 `env` settings override `environment_vars` settings. 51 52 - `environment_vars` (array of strings) - An array of key/value pairs to 53 inject prior to the execute_command. The format should be `key=value`. 54 Packer injects some environmental variables by default into the 55 environment, as well, which are covered in the section below. 56 57 - `execute_command` (string) - The command to use to execute the script. By 58 default this is `{{ .Vars }}"{{ .Path }}"`. The value of this is treated as 59 [template engine](/packer/docs/templates/legacy_json_templates/engine). This is a 60 [template engine](/packer/docs/templates/legacy_json_templates/engine). Therefore, you may 61 use user variables and template functions in this field. In addition, there 62 are two available extra variables: 63 64 - `Path` is the path to the script to run 65 - `Vars` is the list of `environment_vars`, if configured. 66 67 - `remote_path` (string) - The path where the script will be uploaded to in 68 the machine. This defaults to "c:/Windows/Temp/script.bat". This value must 69 be a writable location and any parent directories must already exist. 70 71 - `start_retry_timeout` (string) - The amount of time to attempt to _start_ 72 the remote process. By default this is "5m" or 5 minutes. This setting 73 exists in order to deal with times when SSH may restart, such as a system 74 reboot. Set this to a higher value if reboots take a longer amount of time. 75 76 @include 'provisioners/common-config.mdx' 77 78 ## Default Environmental Variables 79 80 In addition to being able to specify custom environmental variables using the 81 `environment_vars` configuration, the provisioner automatically defines certain 82 commonly useful environmental variables: 83 84 - `PACKER_BUILD_NAME` is set to the [name of the 85 build](/packer/docs/templates/legacy_json_templates/builders#named-builds) that Packer is running. 86 This is most useful when Packer is making multiple builds and you want to 87 distinguish them slightly from a common provisioning script. 88 89 - `PACKER_BUILDER_TYPE` is the type of the builder that was used to create 90 the machine that the script is running on. This is useful if you want to 91 run only certain parts of the script on systems built with certain 92 builders. 93 94 - `PACKER_HTTP_ADDR` If using a builder that provides an HTTP server for file 95 transfer (such as `hyperv`, `parallels`, `qemu`, `virtualbox`, and `vmware`), this 96 will be set to the address. You can use this address in your provisioner to 97 download large files over HTTP. This may be useful if you're experiencing 98 slower speeds using the default file provisioner. A file provisioner using 99 the `winrm` communicator may experience these types of difficulties.
